Please See!
I am very sorry to inform people that this guide is currently not up to date and currently does have substantial areas of information now missing.
For all things relating to before the Halloween update 2019 this guide should still be relevant.
Many thanks for viewing the guide and sorry for the inconvenience.

This guide assumes the player is playing Realism Mode however this guide is still relevant to those playing Classic Mode.

Recent News:
Cat Goes Fishing received an update on 30/10/19
I will attempt to update this guide as quickly as possible

This guide tries to encompass most of the content in Cat goes Fishing in order to help the player.
For other sources of information there are several youtube creators who have provided many walkthrough videos of content for Cat Goes Fishing. There are also other guides available on Steam.

This guide includes information on:

• Game Modes
  
  
• World Maps
  
  
• Weather / Time (I only briefly touch upon this topic)
  
  
• Bait
  
  
• Rods & attachments
  
  
• Shops & Extras (E.g. Rockets, Sonar etc...)
  
  
• Boats
  
  
• Hats
  
  
• Fish
  
  • 100% of fish for each category are shown in their respective overviews however only some fish have "Guides" on how to catch them. This is because the large majority of fish will just be found by progressing through the game naturally and don't have any particular unique methods or locations when it comes to finding and catching them other than occasionally you're required to be persistent.
    
  • The new fish added to the game on 21/04/18 have been added to the guide
    
  • Fish prices in game may change over time
  
  
• Effective methods of making money
  
  
• Achievements
  
  • Including the most recent "Escape The Map" achievement!

If you wish to find any information about a certain specific topic e.g. Cave Shark, I recommend you to use CTRL F. Alternatively just go to their respective category and browse through it. Thank you.

Before going through this guide please keep in mind that it may contain what you'll consider to be spoilers.
This is especially true if exploration and discovering the ins and outs to this game is something you wish to accomplish by yourself.

I just feel this is an obligatory notification to give to you, the player.

Please enjoy the guide and if you have any questions or requests about a specific aspect then please write a message in the comments section at the bottom of this guide and I'll do my best to respond as soon as possible.

Thank you.

The first time you begin Cat Goes Fishing you will be presented with the choice of two game modes.


Ultimately the game modes break down simply into these differences

Realism

• Fish pull on the line / can snap the line
  
• Can unlock all achievements in Realism Mode

Classic

• Fish won't fight back
  
• Not all achievements are available to unlock in Classic Mode

I would recommend the player choosing Realism mode. I perceive realism as more fun due to the fish being difficult in some circumstances as well as the player being able to unlock all achievements.

If you wish to change to the other game mode you will have to press 'ESC' and start a new game in which you will be presented with the choice of game mode again

This section shows an image of the entire world map from the surface and images of the ocean bed and cave systems.

• The maps shown may be inaccurate by a few of pixels in certain areas

Ocean Map

Ocean Floor & Caves

• The Ocean Floor Map only goes up to the far reef.
  
• The map features appear larger due to an increase in the zoom of the map when you reach the Ocean Floor and Caves.

Max Distances of Boats on the World Map

Max Depth of Rods on the World Map (With the Sinker Attachment)

Useful Areas to Note in Caves

There are 3 types of weather to experience in Cat Goes Fishing

• Day
  
• Night
  
• Stormy

Day

• Most common condition
  
• Largest variety of fish

Night - Unlocked at level 16

• Much fewer small fish
  
  • The player will mostly have to fish deeper in order to catch small fish
    
  • The Bait Hat works well at night
• Decreased overall variety of fish
  
• Cave fish will venture out from caves
  
• Noctis will appear
  
• Wearing the Nightfall hat = "The sun never rises, and storms are more frequent."

Without the Nightfall hat the game follows this cycle for day and night:

Storms

• Essentially Night with lightning effects
  
• Similar fish as Night
  
• The Stormy fish will surface

There is most likely much more to both Storms and Night than what this guide provides information on in their regards.

All hats apart from the Explorer hat will spawn randomly along the sea floor or in cave entrances. To find all hats you will be required to scour the sea floor. Hats are also found sinking to the bottom when they first spawn.

Each hat offers its own perk.
There are 26 hats in total to acquire. Each hat is assigned a category. These categories are:

• Common
  
• Uncommon
  
• Rare
  
• Legendary
  
• Discovered
  
• Mythic

At level 20 the player unlocks the Hatalog. This is a catalog of the hats you have found enabling you to purchase them and allows the player to see the % of hats they've found.
All hats apart from Mythic are available for purchase when obtained for the first time through fishing.
All hats apart from Discovered can be found sinking to the bottom or resting on the sea bed.

List of all Hats in Cat Goes Fishing

A guide titled 'Cat Goes Fishing 100% Attainable Hats' by Dr VonSpoot is also available which provides information on the perk each hat offers.

• There is only one hat in the game which falls under the Discovered category

The Explorer

Minimum requirements to get:

• Good Boat
  
• Quick Rod
  
• Sinker
  
• Light bulb

Directions

• For a better view / understanding of the Explorer Hat location, please go to World Maps section of the guide.

• There are a total of 33 small fish to catch in Cat Goes Fishing.
  
• All small fish apart from the Bombat will take any size bait unless a Bait Guard rod upgrade is equipped
  
• The Bait Guard upgrade will prevent small fishing from taking large bait.
  
• Small fish can be cast back into the ocean to make a medium bait.
  
• Monetary values of fish may change over time

List of All Small Fish in Cat Goes Fishing

Upon completion of the small fish's catalogue, it will say "Completion: 101%" unlike the other sections which will only be 100%. As of the April 2018 Update the catalog will now be 100% complete instead of 101%
Small Fish - Part 1 Contains:

• Bombat
  
• Sassy - Added to Cat Goes Fishing on 21/04/18
  
• Skrimp

For Information on the Yin & Yang please go to "Small Fish - Yin & Yang"

Only selected fish are written about due to the majority of fish being widespread and easy to catch / very likely for you to catch just through casual play and progressing naturally.
Small Fish - Part 1 Contains information of where to find / how to catch the following:

• Bombat
  
• Sassy - Added to Cat Goes Fishing on 21/04/18
  
• Skrimp

For information on how to catch both Yin & Yang please go to the section "Small Fish - Yin & Yang".

Bombat
Note!: In the image available from the catalog, the Bombat appears to be bugged in that it shows its normal image overlaying its "Biting" image.

The Bombat is incredibly easy to catch though can be a pain in your rear end to get it to the surface without other fish eating it. To help avoid this use Bomb Stack & Detonate rod attachments to clear fish on your way down.
You will want:

• Quick Rod
  
• Sinker

With these two attachments you have everything you need to easily access areas where Bombats are.
Simply sink to the sea floor and pick up a stone, then carry the stone and allow it to sink into the cave systems. A Bombat will be eager to bite it.
Bombats will also bite Bombs however this will not catch them due to the bomb eventually exploding.


Sassy

• The Sassy was added to Cat Goes Fishing in an update on 21/04/18
  
• The Sassy is the only Small Fish added on 21/04/18 not found beyond the far reef

What you need:

• Dark Boat
  
• Quick Rod + Sinker Rod Upgrade
  
• Will likely want to bomb a clearance of larger fish to prevent the Sassy from being eaten while reeling

Location

• The Sassy congregate as a group in close proximity to the sea bed tree

Skrimp

Skrimp are very easy to catch but are only in one location (View world maps section to see exact location).
You will want:

• Power Rod
  
• Dark Boat
  
• Sinker
  
  • Crank Bait is ideal

Simply sink your line to their location and drag the line through their shoal.

Yin & Yang Difficulty: 3

The Yin & Yang fish have their own section due to the unique requirements for catching them.

• The Yin & the Yang require being with each other before they will bite the bait.
  
• The Yin & Yang are opposite sides of the map (Look at the World Maps section of the guide to see the locations of the Yin & the Yang)

Equipment: (In bold is equipment which is definitely required)

• Battery Pack Hat (Only Briefly required)
  
• Explorer Hat
  
• Starting Bait
  
• Advanced Sonar
  
• Master Rod, Attachments:
  
  • Detonate
    
  • Bomb Stack
    
  • Sinker
    
  • Crank Bait - Allows for easy descent
• Luxury Boat

Step 1 - Prep

• Buy the Battery Pack Hat
  
• Buy a light and equip 5 bombs (The light will now last for 30 minutes)
  
• Sell the Battery Pack Hat
  
• Find or buy the Explorer Hat
  
  Step 2 - Clearing
  
• Using the bombs you purchased in Step 1 clear the area below:

Step 3 - Get the Yangs attention

• Go to the Yang with your lure

• The Yang will form 1 fish and follow your bait

Step 4 - Route

• Ensure to go at a slow enough pace that the Yang doesn't lose sight of the bait
  
• Go the route as drawn on this map:

• I would recommend to Not go out of the cave system if you are able to go through it. Leaving the caves can cause the Yang to begin swimming frantically.
  
• If this happens you will not be able to get the Yangs attention again.
  
• The Yang will continue swimming in a motion like this (See image below) until eventually leaving the map which will require you to close the game and reopen it in order to respawn the Yang.

Step 5 - Combine Yin & Yang

• Lead the Yang exactly to the Yin
  
• The Yang will leave your bait to begin swimming in a circle with the Yin
  
  • The single Yang should return to 3 fish (If you haven't lost any along the way)
    
  • You will need a minimum of 2 but don't be alarmed if the Yang stays as 1

Step 6 - Catching

• Come to the surface
  
• Buy bombs and ensure a clear path between the fish and your boat
  
• Buy a light if yours has run out in order to keep the Moga away
  
• The Yin & Yang require only starting bait
  
• Catch like you would any other fish but don't catch all 3 of 1 kind first otherwise you will need to repeat the process.

Note
Watch out for the Yang getting stuck in the rocks. While gathering the pictures for this guide by repeating this process I lost 2 of my Yang by them becoming lodged and stuck in the ceiling of a cave. This is why I only have a picture of a caught Yin.

• There's a total of 28 medium fish in Cat Goes Fishing.
  
• Medium fish require a small bait or higher.
  
• Medium fish can be cast back into the ocean to make a large bait.
  
• Monetary values of fish may change over time.

List of All Medium Fish in Cat Goes Fishing

Medium Fish - Part 1 Contains:

• Bleaper
  
• Cavin - Added to Cat Goes Fishing on 21/04/18
  
• Cray Fin
  
• Lion Fish
  
• Snoutfish
  
• Stormy

All medium fish require a small bait or higher.

Part 1 Contains:

• Bleaper
  
• Cavin - Added to Cat Goes Fishing on 21/04/18
  
• Crayfin
  
• Lion Fish
  
• Snoutfish
  
• Stormy

Bleaper

• The Bleaper is easily found at night swimming around your boat. A medium bait is required.
  
• Simply hang the bait in the water nearest the boat and the bleaper will eventually bite. Reel in.
  
• The description idicates the Bleaper may jump and take the bait when you haven't cast. This may be true however I had no success when waiting 2 minutes.

Cavin

• The Cavin was added on 21/04/18
  
• The Cavin is the only Medium Fish added on 21/04/18 which isn't located beyond the far reef
  
• Despite the information provided by the Catalog the Cavin can be found just outside the cave lingering above the sea floor as shown below during the day

You will want:

• Basic Boat
  Sinker Attachment with a rod which can reach the sea bed

Location:

• The Cavin is located on the sea bed close to shore
  
• There is a high risk of the Cavin being eaten while reeling in - Recommend using bombs to clear a path to the surface before hand

Crayfin

In truth the Crayfin just needs a little bit of persistence and a slight touch of luck.

• The Crayfin can be found at the Chompers side.
  
• The Chomper will regularly steal the bait
  
• Having the Chomper steal the bait the first time can cause the Crayfin to become slightly distanced from the Chomper - Making it easier to catch
  
• Alternatively catch the chomper first, throw it back in and then quickly attempt to catch the Crayfin while it's close to the boat. (There are chances you can still catch the Crayfin if you put the Chomper in the boat)
  
• If the Chomper is still present it will snap the line for the Crayfin.

You will want:

• Power Rod
  
• Dark Boat or Luxury Boat
  
• Sinker
  
• Crankbait

Lion Fish

Found at the furthest reef. The Lion Fish won't take bait and will require a live fish.
You will want:

• Luxury Boat
  
• Small bait
  
• Huge Hook
  
• Sinker
  
• Crank Bait

Method

• Huge Hook on a small / starting bait
  
• Catch a small fish found on the reef
  
• Drag it to a Lion Fish
  
• Lion Fish will bite and then reel in Lion Fish

Snoutfish

The Snoutfish can be caught by accident as it will occasionally be on the side of large fish. However if you're impatient you can find the Snoutfish in a certain area in the cave systems (As Shown on a World Map in the World Maps Section).
What you will need:

• Dark Boat
  
• Luxury Rod
  
• Sinker

Method

• There is no unique method for catching the Snoutfish.

Stormy

• The Stormy comes out during storms
  
• It will sit in front of a cave entrance continuously "Flicking" between facing towards the surface and facing towards the sea floor
  
• The Stormy is relatively easy to catch

You will want:

• Quick Rod
  
• Speed Boat
  
• Sinker

• There are 31 large fish in Cat Goes Fishing
  
• All large fish require a large bait
  
• Monetary values of fish may change over time

Complete list of large fish in the game


Large Fish - Part 1 Contains:

• Bagu
  
• Bonefish
  
• Brimble

• All large fish require a large bait.

Large Fish - Part 1 includes:

• Bagu
  
• Bonefish
  
• Brimble
  
• Lemonback

Bagu

• Typically only 2 Bagu on the map at any 1 time
  
• The Bagu will put up a strong fight before eventually tiring
  
• Can be found swimming as a pair between Mid distance and far distance from shore (Usually far / will likely want to have the luxury Boat).

Bonefish

• Bonefish are found sleeping on the cave floor just outside of the Cave Shark's cave.
  
• Bone fish will wake if a bomb detonates in close proximity to them.
  
• Bone fish swim incredibly fast.

Location

View World Maps section for the full picture of World Map

What you'll want:

• Speed Boat
  
• Master Rod
  
• Sinker
  
• Detonator
  
• Light

Method

• Equip a bomb
  
• Go to cave floor where the Bonefish are present
  
• Detonate bomb next to Bonefish to wake it
  
• Once woken, with a large bait wait here:

• Bonefish swimming around frantically should come across your bait and bite it
  
• Reel the Bonefish in

Brimble

• The Brimble can be found next to the shore at middle depth.
  
• Brimble sit in a vertical orientation facing either downwards or upwards.
  
• The Brimble will apply constant pulling force on the fishing line.
  
• Brimble take a considerable amount of time to catch compared to the majority of fish.
  
  • I usually voluntarily snap the line due to it being a slight pain to get them up to the boat.
    
  • You can see in the Sonar picture the path usually taken to bring up the Brimble.

I moved side to side in a boat to better display how brimble edge up in a slow, gradual manner.
The key to catching a brimble is getting the right rythem. Focus on the colour of the line and only release momentarily when it's becoming bright red / just about to snap but quickly reel again.

Lemonback

• The Lemonback resides in a deep cave underneath the far reef.
  
• If you are lucky you may find them outside of the cave and in the same location as the Yin but this is unusual and not to be expected.
  
• Lemonbacks will swim in a pair or as a three.

Location

View World Maps section for the full picture of World Map

Minimum Requirements

• Luxury Boat
  
• Master Rod
  
• Sinker

Method
You need to lure the Lemonback outside of the caves before allowing them to bite otherwise the line will snag. I recommend you practice quickly getting the line out of their small cave entrance before luring them.

• Navigate your hook with a large bait into their cave and get their attention
  
• Lure them out of the cave to at least the location of the Yin
  
• Allow them to bite the large bait
  
• Reel in

• Fish are in alphabetical order
  
• All large fish require a large bait.

Large Fish - Part 2 includes:

Minimum Requirements

• Master Rod
  
• Gauge x3
  
• Improved Crank

Recommended Method
Lure these fish as close to the boat as you can before allowing them to bite the hook.


Nightfish Sire - The Money Maker

• The Nightfish Sire is the best method of earning money.
  
• Contrary to the name they are still present during the day.

Location
Minimum Requirements:

• The Good Boat
  
• A large bait

• Luxury Boat
  
• Rocket
  
• Large Bait

• Catch both Torby to unlock the achievement "Oops".

• Both Torby are usually together however one may be swimming off in the distance but will remain fairly close in proximity.
  
• One Torby will always be stationary in deep sea.

• The player will want the Luxury Boat.
  
• You only require a large bait to catch the Torby.
  
• When the first Torby is caught the second Torby will begin to swim around it.

Dragon Fish

The Dragon Fish was added to Cat Goes Fishing on the 21st of April 2018

• Reel the Shark in - The Shark will both reel up and dive vertically, you will repeat this process with each period of reeling resulting in the Shark getting slightly nearer to the surface.

Tiger Shark Difficulty: 2

• The Tiger Shark will put up a quick bout of resistence but will easily tire and reel in.
  
• Expect the first three attempts to get the Tiger Shark into the boat to be met with a sudden dive.
  
• The tiger shark is approximately 15 - 20 seconds from shore when travelling in the luxury boat and found at mid depth.

Recommended Equipment
-Extra: Huge hook
-Bait: Large
-Rod: Any but higher = better, Attachments:

• Gauge
  
• Improved Crank

Method

• Use a large bait and a Huge hook
  
• Have it in the approximate vacinity
  
• Wait for tiger shark to bite

Location



Maw

• The Maw can be found close to the shore slightly right to the area you'd find the Shark
  
  • Alternatively the Maw may be swimming around the map swallowing up Bulb Fish.
• The Maw will be in deep sea
  
• The Maw seemingly surfaces easy but will dive hard in an attempt to snag the line and give a good fight when you first get the Maw close to your boat. (Sometimes you can get lucky and it does just surface easy the entire way)
  
• The Maw may have a Bulb Fish in its mouth or will be swimming around swallowing Bulb Fish.

Recommended Equipment
-Boat: Good Boat
-Extra: Huge Hook and light
-Rod: Master Rod (A Power Rod is capable of catching the Maw). Recommened attachments:

• Gauge x3
  
• Improved Crank x3
  
• Crank Bait
  
• Sinker

Method

• Drop in line with no bait and a Huge hook
  
• Wait for the sinker to reach the mouth of the Maw
  
• Reel the line to catch the Bulb Fish located in the Maws mouth (Or the Bulb Fish closest to the Maw)
  
• The Maw will almost instantly bite the Bulb Fish
  
• Reel in the Maw
  
• At times the Maw will dive and snag your line on the sea bed and not much can be done to stop it

Location



Sword Fish Difficulty: 2

The Sword Fish can often be found swimming near the surface. A Puff is needed to catch the Sword Fish.

Recommended Equipment
-Boat: Speed Boat. The Sword Fish may be within reach with the good boat when it frantically swims along the surface.
-Extra:

• Huge Hook - A Huge hook is not necessary, no need to purchase.
  
• A light if you're going to catch it from the deep.

-Rod: Quick Rod or better. Recommened attachments:

• Gauge x2
  
• Improved Crank x1

Method

• Purchase a Huge hook. - Not necessary.
  
• Catch a Puff. The Puff will inflate meaning no other fish will eat the fish.
  
• Using Sonar, identify the pathways of the sword fish.
  
• Keep the puff dangling around these pathways.
  
• Swordfish will get its nose stuck to the Puff.
  
• Reel in accordingly. The Sword Fish will provide about a minutes fight then sort of concede. Once it has conceded it will still require you to reel in gradually to avoid snapping the line.

Alternatively

• Locate Sword Fish's location near the sea bed (Advanced Sonar recommended).
  
• Have the Sinker attachment.
  
• Buy Huge hook and catch Puff.
  
• Allow Puff to sink to the depth where the Sword Fish is.
  
• Maneuver the Puff and Huge Hook over the Sword Fish's nose.
  
• The Sword Fish should be relatively easy to reel to the surface. Once the Sword fish gets close to the surface it will begin to pull.

Special thanks to Cett for highlighting mistakes involving the Sword Fish and Maw in the comments below.

Huge Fish - Part 2 covers:

• Moga
  
• Noctis
  
• Cave Shark
  
• Hamahed - Added to Cat Goes Fishing on 21/04/18

Moga Difficulty: 3

• A good location to attempt to catch the Moga is towards the end of the map just before the reef with the Lion Fish.
  
• The Moga needs a large bait
  
• The Moga needs a Huge hook
  
• The Moga requires darkness - Do not have a light
  
• The Moga will obscure the view of the fishing line

Recommended Equipment
-Boat: Good Boat or better. Not the Dark Boat if using a light to navigate down deep.
-Extra: Huge Hook
-Rod: Great Rod or Master Rod. Recommened attachments:

• Gauge x3
  
• Improved Crank x3

Method

• The Moga will have a slow but fairly easy initial ascent when using a rythmic reeling method.
  
• The difficulty comes to getting the Moga into the boat.
  
• The fishing line will be obscured however you will be able to see the fishing line in the Mogas mouth.
  
• The key to reeling the Moga in is patience and reeling to a slow but steady rythem.
  
• The rythem you employ to first ascend the Moga may need more finese for the final short stretch.

Location

• The Moga follows beneath your boat in deep sea.

Noctis Difficulty 1 - 3

• The Noctis can only be found at night or during storms.
  
• The Noctis will swim at every depth in a fast, frantic manner.
  
• The Noctis will grab any fish you catch and drag it around momentarily. Sometimes this results in the hook becoming snagged on the sea bed.

Recommended Equipment
-Boat: Any Boat, better = can move more appropriately towards the Noctis.
-Bait: Large
-Extra: Huge Hook & Sonar
-Rod: Any if method is done right. Recommened attachments:

• Gauge x2
  
• Improved Crank x1

Method

• The Noctis takes a large bait with a Huge hook.
  
  • It doesn't take live bait even though its habit of running off with your live fish might deceive you.
• Have your line just beneath the surface of the water and wait patiently for the Noctis to bite.
  
  • You can use Sonar to move yourself better towards the Noctis.
• As soon as it bites reel in as soon as possible.
  
• Should easily be caught due to how near the surface the hook is.
  
• If you fail to quickly catch the Noctis it can put up a large fight and can snag your line on the sea floor.

Location

• Everywhere / No single location

Cave Shark Difficulty: 3

Arguably the most difficult fish in the game to catch. The cave shark aggressively swims towards the sea bed to snag the line causing the player to start again. The cave shark will apply a lot of pull on the line which will regularly cause breaking of the line. Expect to need to take multiple attempts.

I have caught the Cave Shark twice using the same methods. I have however seen videos on youtube where people use bombs to stun the Cave Shark before it snags the fishing line so would also recommend looking into that if my method does not help you.

Recommended Equipment
-Hat: Battery Pack - Surgeon may seem the best option but it really doesn't make any difference.
-Boat: Speed Boat
-Extra: Bulb
-Rod: Master Rod, Attachments:

• Scouting (Must have)
  
• Sinker (Must have)
  
• Gauge x3
  
• Improved Crank x3

Method

• DO NOT buy the Huge hook
  
• Buy light bulb
  
• Cast next to boat. Allow bait to sink to the bottom. (May need to clear the path in advance)
  
• Pick up a rock from the sea floor
  
• Continue towards shark
  
• Bombat should attach to rock on the way
  
• Shark will bite the bombat
  
• The shark will direct itself out of the cave. Player must prevent it from touching the bottom.
  
• Once out of the caves the shark will continuously attempt to snag the line

- It will repeatedly go for this spot

• Reel in aggressively only letting up slightly before the line snaps
  
• Use the boat (This is extremely important) to help with pulling the shark away from the spot it attempts to snag the line (Must be reeling for the boat to move the shark)
  
• Shark will eventually tire after multiple (Many) attempts to beach the hook

Route the cave shark takes out:
Areas in red is where the shark will attempt to snag the line
Purple line represents the movement of the Cave Shark


Directions

• For better understanding of the Cave Sharks location please view the World Maps section.

Hamahed Difficulty: 1 - 2

The Hamahed was added to Cat Goes Fishing on the 21st April 2018

• The Hamahed is located beyond the far reef swimming at a mid depth.

Recommended Equipment - The Equipment I used:
-Hat: N/A
-Boat: Luxury Boat
-Extra: Huge Hook & Rocket
-Rod: Master Rod, Attachments:

• Gauge x3
  
• Improved Crank x3

Method
Having a large bait, Huge hook and rocket, cast out as far as you can and bring your hook to the Hamahed. The Hamahed will take the bait and begin spiralling applying medium force to the line. Tap reel to prevent breaking of the line and beware potential periods of being incapable of seeing the line. Sail your boat left bringing the Hamahed into the deeper water before the reef to be safe incase it would dive to the sea bed. Persist until eventually the Hamahed concedes and no longer applies force. The Hamahed will ocassionally appear to be surfacing but will suddenly apply pressure before getting into the boat.



Nessy Difficulty: 4
Nessy has yet to be found in Cat Goes Fishing. Some believe it only exists in a loched file. Others believe it not to exist in the games files at all.

Fish Profile



Sodafish

• The Sodafish currently is out of reach unless you swim to it
  
• The Sodafish doesn't contribute any known % to the Catalog or make an appearance in the Catalog for now
  
• You can grab hold of the Sodafish while swimming indicating it is a Medium Fish

Comment about the Soda Fish from the Cat Goes Fishing Dev:

Under Construction

This section isn't going to be greatly in depth. The reason for this is eventually you'll be earning far more than you can possibly spend while at the beginning not much is available to you.

There are 2 ways to make money in this game:

• Quests
  
• Fishing

Fishing is by far the most effective when compared to quests.

If you're in this section I imagine you're asking "What is the number 1 fastest way to earn dosh?". Unfortunately there are no real short cuts but there certainly is a spot or two ripe with those expensive fish.

Nightfish Sire
The Nightfish Sire is worth an incredible $380,000 making it the second most valuable fish in the game and unlike the Cave Shark (The #1 most valuable fish at $400,000) it is extremely easy to catch, given that you have at minimum:

• The Good Boat
  
• A large bait
  
• Quick Rod + (Quick Rod requires patience for the fish to bite)
  
• Sinker (Unlocked at level 25)

At their spawn you will find 3 each time you restart the game. Just catch all 3. Save game. Turn off the game. Open up game and repeat the process to your hearts content.
The most difficult part of catching a Nightfish Sire is simply getting the large bait down to it.
View 'Large Fish - Part 3' for more information on catching the Nightfish Sire.

"What if I'm not level 25 and have just started the game?".
You will want to perform quests, sell most of what you catch in the beginning, start going for Large fish etc... One of the most recommended methods however available to early players is the "Kingfish" method:

Kingfish Method

• Catch a Queenfish

• This will cause a swarm of Kingfish to come next to shore or your boat as they follow the Queenfish.
  
• Simply throw your line in and pick them out with ease to earn several thousand with very little effort or time spent.

In the grand scheme of expenses this method really doesn't provide much. With that said though, for new players this can provide a quick bulk to be able to afford what your heart desires. Within a few hours you'll be hitting your first million so don't despair!

• Achievements - Part 1 focuses on "Collective" achievements. Achievements which are mostly self explanatory and standard such as "Catch _______ on Realism".
  
• There are 53 achievements available to obtain in game.
  
• Achievements - Part 1 covers 42 achievements.
  
• The game has undergone several major updates since the final listing of achievements were published.

Quest Achievements Total: 4

• There are 4 achievements to acquire through quest completion.
  
• Master Quester is likely to be the last achievement you'll need.
  
• It will be very long and tedious to acquire the Master Quester.
  
• It will feel like you've done 100 quests long before you've unlocked the achievement.

Things that can help:

• Max quests increase to 2 at Level 15.
  
• Max quests increase to 3 at Level 30.
  
• Ball Cap increases max quests by 1.
  
• Quester's Beret increases max quests by 2.
  
  
• At Level 30 with the Quester's Beret you will be able to have 5 quests at once.
  
  • This helps massively with saving time due to not needing to go to shore as soon. This also increases likelihood of completing a quest just through happen chance.

• It is recommended that players focus on quests straight from the beginning when after these achievements.
  
  • Personally I find that quests mainly serve to be irritating and at times punishing. This becomes more apparent the longer you leave quests because doing a quest for an obscure small fish found in the depths with nothing but a minimap is a massive pain.
  Some players have reported a bug in which they no longer receive more quests after a while (Notably 100% of all fish caught) preventing them from getting to 100 quests.
  The 100 Quests have to be achieved on a single save file.
  There is no known fix in game for this bug and the player may be required to start a new save file to even have a chance of acquiring the achievement.
  This issue may be resolved in an upcoming expansion for the game.
  
• As of April 2018 if players are experiencing the bug of being unable to obtain new quests which is preventing them from obtaining the "Master Quester" achievement, they are now able to reset the catalog which allows them to obtain new quests.

Rods Total: 5

• Simply purchase each rod to obtain all of these achievements.

Rod Upgrades / Attachments Achievements Total: 8

• I recommend visting the Rod Attachments / Upgrades section of the guide to see what level you need to reach for each upgrade relevant to the achievement.

Catch [Insert Fish] Total: 16

• Catch each of these fish in Realism Mode to unlock each achievement. View the relevant Fish sections of the guide to find information on how to catch them.
  
• Due to the achievements list being older than a lot of updates, you are only required to catch certain fish (This is because fish have progressively been added to the game).

Unlocks From The Tool Shop Total: 2

• There is no achievement for unlocking the Advanced Sonar
  
• Information on how to get the Minimap and Sonar are available in the Tool Shop section of the guide.

Unlocks From The Lure Shop Total: 2

• Catching a Queenfish to lure in loads of Kingfish can be useful for achieving "Boom!"
  
• For information on unlocking the Lightbulb please see the Lure Shop section of the guide.

Hat Achievements Total: 2

• View the Hats - Overview section of the guide to see the list of hats which will help you to see what you're searching for.

Boat Achievements Total: 3

• The Great Boat no longer exists however the achievement is still unlocked by purchasing the other boats
  
• For information on boats please go to the Boats section of the guide.

Oops

• Catch both Torby in a single save file to unlock this achievement.

Large Fish - Part 2 has information on catching the Torby.

Clever Cat

• Catch the shark using the Basic Rod to unlock this achievement.

Huge Fish - Part 1 has information on catching the Shark.

Attraction

• Buy 3x Attract for any one fish species on a single rod.

Avoidance

• Buy 3x Repel for any one fish species on a rod.

Patience

• Buy 2x Suspending Lure attachments on your rod.

Impatience

• Buy 5x Diving Lure attachments on a single rod (Power rod or above needed)

Fine Tuning

• Have an Increase and Decrease Sink Speed attachment equiped on your rod at the same time.

Brute Force

• Buy Improved Crank for 5 attachment slots of a fishing rod (Power Rod or above needed)

Perpetual Motion

• Have the shark drag your live fish down 3x

The Shark will take live fish without a Huge hook and it will result in turning that fish into bait once let go. Using this bait catch another fish and repeat until it has happened 3 times.

Suntouched

• Throw a large fish back in to the ocean

• The achievement "Escape The Map" was added in April 2018

Thank you very much for reading. Hope you found this guide helpful.
Feed back is always welcomed and if you are aware of any existing mistakes please notify me to make changes.

Also if you wish for me to add any other content to the guide such as going more in depth in a particular area or adding a catching guide for a particular fish not given an extra part in this guide do please just ask as I have done pieces for a lot which I ended up retracting from this guide in an attempt to better compact it.

Thank you very much and all the best.
