Fishing is only the setup. The real game is dragging hostile sea creatures onto land, killing them before they escape, and selling the remains to fund better weapons.

The most reliable progression loop is simple: collect free food, farm the strongest boss you can beat safely, and upgrade firearm damage before entering the next island. Follow that rule and the campaign becomes far less punishing.

Use this route from the crash island to the final boat.
| Step | Action | Main Goal |
|---|---|---|
| 1 | Collect clams | Secure free food |
| 2 | Catch and sell crabs | Build starting cash |
| 3 | Buy brass knuckles | Kill small creatures faster |
| 4 | Save for the knife | Prepare for the first boss |

| 6 | Defeat the crab boss | Get boat keys |
| 7 | Travel to Swamp Island | Unlock firearms |
| 8 | Collect leeches | Get special boss bait |
| 9 | Buy the shotgun | Beat the giant piranha |
| 10 | Farm fish and piranhas | Build mid-game cash |
| 11 | Travel to Beach Island | Unlock grilling and the SMG |
| 12 | Farm sharks | Buy and upgrade the SMG |
| 13 | Defeat the pufferfish | Get new coordinates |
| 14 | Travel to Casino Village | Buy the sniper |
| 15 | Defeat the tuna and giant bird | Unlock Volcano Island |
| 16 | Travel to Volcano Island | Buy the assault rifle |
| 17 | Upgrade the assault rifle | Prepare for the final bosses |
| 18 | Defeat the whale | Start the volcano sequence |
| 19 | Defeat the mutated whale | Get the final keys |
| 20 | Board the final boat | Finish the game |
Do not rush islands just because you unlocked new coordinates. Each island expects a major damage upgrade.
↖ Starter Island: Food, Fishing, and Boat Keys
Your first objective is to turn free resources into enough cash for the knife.
↖ Starter Island Priorities
1. Collect every clam you see.
2. Catch and sell crabs, shrimp, and other basic creatures.
3. Buy brass knuckles if your fists are slowing you down.
4. Save for the knife.
5. Get the empty beer can bait.
6. Defeat the crab boss.
7. Collect the boat keys and use the radar.
Clams are your free healing and hunger supply. Spending early How to Fish Gold on food delays the knife and makes the first boss harder than necessary.
| Item | When to Get It | Purpose |
|---|---|---|
| Clams | Immediately | Free food and recovery |
| Basic Fishing Rod | Early | Required for normal catches |
| Brass Knuckles | Early | Better than fists |
| Knife | Before the crab boss | Strong early melee damage |
| Radar | Before leaving | Locates the next island |
| Boat Keys | After the boss | Unlocks island progression |
↖ How Fishing Works
Use the same process for most catches:
1. Face open water.
2. Cast as far as possible.
3. Wait for a bite.
4. Reel until the creature is hooked.
5. Complete the required input.
6. Pull the creature onto land.
7. Kill it before it reaches the water.
8. Sell it or save it for a quest.
Fish from a position that forces the catch to land farther inland. Those extra seconds often decide whether you get paid or watch your catch flop back into the ocean.
↖ Best Bait and Lure Progression
Better lures increase catch value and unlock bosses. Once your economy is stable, fishing without bait is usually wasted time.
| Fishing Setup | Best Use | Value |
|---|---|---|
| No bait/basic bait | Starter grinding | Low |
| Hot dog bait | Early catch variety | Low to medium |
| Beginner lure | Early fish and mini-bosses | Medium |
| Boss lure | Repeatable Gold farming | High |
| Professional lure | Late-game bosses | Very high |
| Scientific lure | Volcano Island catches | High |
Use basic catches to fund your first weapon. Use boss lures to fund everything after it.
↖ Beer Can Crab Boss Strategy
Speak with the relevant starter-island NPC to get an empty beer can, then use it as bait to summon the first boss.
↖ Recommended Loadout
| Gear | Minimum | Recommended |
|---|---|---|
| Weapon | Brass knuckles | Knife |
| Food | 2–3 clams | 5 or more clams |
| Position | Open beach | Center of the island |
| Combat style | Trade hits | Hit, retreat, recover |
The brass knuckles can win, but the knife makes the fight shorter and safer.
↖ How to Beat the Crab Boss
- Pull it away from the ocean.
- Attack after it moves or misses.
- Step back instead of trading every hit.
- Eat before your health becomes critical.
- Keep attacking often enough to beat the timer.
The timer punishes passive play. The winning approach is controlled aggression: attack, create space, heal, then re-engage.
Defeating the crab boss awards the boat keys.
↖ Island Progression and Best Weapons
Each island introduces a stronger boss, a better income source, and a new weapon tier.
| Island | Main Objective | Free Food | Key Weapon | Main Threat |
|---|---|---|---|---|
| Starter Island | Unlock the boat | Clams | Knife | Crab boss |
| Swamp Island | Unlock guns | Leeches and piranhas | Shotgun | Giant piranha |
| Beach Island | Unlock grilling | Clams and fish | SMG | Shark and pufferfish |
| Casino Village | Unlock Volcano Island | Clams and fish | Sniper/SMG | Tuna and giant bird |
| Volcano Island | Finish the game | Snails and birds | Assault rifle | Whale and mutated whale |
The practical weapon path is:
Knife → Shotgun → SMG → Sniper → Assault Rifle
You do not need to replace every weapon immediately. The SMG remains useful against fast ground targets, while the sniper is mainly for flying enemies.
↖ Swamp Island: Leeches, Shotgun, and Giant Piranha
Swamp Island introduces guns and swarm-based combat.
↖ What to Do First
1. Speak with the NPC who needs help with a fish.
2. Search the ground for leeches.
3. Trade the required leeches for special bait.
4. Buy or prepare a firearm.
5. Farm normal fish for cash.
6. Get the shotgun before summoning the boss.
Leeches are easy to miss, so scan the ground carefully. Keep extras as free food.
↖ Is the Shotgun Worth Buying?
Yes. The shotgun offers high burst damage, knockback, and unlimited ammunition. It is especially strong against clustered piranhas.
| Weapon | Best Trait | Main Weakness |
|---|---|---|
| Knife | Cheap, strong melee damage | Dangerous against swarms |
| Shotgun | Burst damage and knockback | Can push targets awkwardly |
| Pistol | Usable starter firearm | Weak boss damage |
↖ Giant Piranha Boss Strategy
The giant piranha spawns smaller piranhas. Kill those smaller enemies and eat them when you need health.
- Fight near cover or elevated ground.
- Shoot the boss when it jumps or exposes itself.
- Use shotgun knockback against the swarm.
- Kill small piranhas before they surround you.
- Eat piranhas for emergency recovery.
- Stay away from the shoreline.
The smaller piranhas are not just threats. They are mobile healing supplies. Use them instead of wasting purchased food.
↖ How to Make Gold After Swamp Island
Normal fishing is safe, but boss farming scales much faster.
| Method | Risk | Profit | Best Use |
|---|---|---|---|
| Normal fishing | Low | Low to medium | Safe starter income |
| Beginner boss lure | Medium | High | First major Gold spike |
| Selling piranha spawns | Medium | Medium | Extra income after the boss |
| Bird hunting | Low to medium | Medium | Easier with shotgun or sniper |
| Gambling fish | High | Unstable | Entertainment, not progression |
The best rule is to farm the strongest boss you can kill consistently. A weaker boss with a near-perfect success rate pays better than a stronger boss that kills you every second run.
Save your money for:
1. Weapon purchases.
2. Bullet-damage upgrades.
3. Recoil control.
4. Magazine upgrades.
5. Better bait.
Cosmetics come last. A stylish gun still loses if it hits like wet bread.
↖ Beach Island: Grill, Sharks, SMG, and Pufferfish
Beach Island is the main mid-game preparation zone. It unlocks cooking, shark farming, the SMG, and stronger boss encounters.
↖ Beach Island Priorities
1. Complete the grill NPC's task.
2. Catch and kill sharks.
3. Unlock the lighter.
4. Grill valuable catches.
5. Farm enough cash for the SMG.
6. Upgrade the SMG's damage.
7. Defeat the pufferfish boss.
↖ When Should You Grill Fish?
Cooking can increase sale value, but grilling every cheap fish wastes time.
| Catch | Grill It? | Reason |
|---|---|---|
| Cheap fish | Usually no | Low return for the time spent |
| Boss fish | Sometimes | Better value, unless needed for a quest |
| Rare or endangered fish | Yes, if sellable | Higher return |
| Quest items | No | Turn them in directly |
Before selling a rare catch, check nearby NPC requirements. Selling a quest item can stall progression and force another fishing cycle.
↖ Shark Boss Strategy
The shark is fast and punishes players who fight in open terrain. Use the island's objects as cover.
↖ Recommended Shark Loadout
| Gear | Recommendation |
|---|---|
| Weapon | Shotgun or SMG |
| Food | Clams or fish |
| Utility | Discs/frisbees |
| Cover | Grill table, trees, or structures |
Placed discs can add damage or disrupt the shark's movement. Put them near routes the shark repeatedly uses.
↖ How to Beat and Farm Sharks
- Stand near the grill, a tree, or another solid object.
- Let the shark approach you.
- Fire while moving backward.
- Break line of sight when it lunges.
- Never chase it into the water.
- Recover before starting another lure.
Once the fight becomes consistent, shark farming provides enough money to buy and improve the SMG.
↖ Best SMG Upgrades
The base SMG has heavy recoil and mediocre efficiency. Damage and control upgrades transform it into a reliable boss weapon.
| Upgrade | Priority | Reason |
|---|---|---|
| Bullet Damage | Very high | Directly improves boss DPS |
| Red Dot/Laser | High | Makes tracking easier |
| Compensator | High | Controls recoil |
| Magazine Upgrade | Medium | Reduces reload pressure |
| Cosmetic Skin | Low | No combat benefit |
Buy bullet damage first. Shorter fights require less food and create fewer opportunities for mistakes.
↖ Pufferfish Boss Strategy
The pufferfish becomes more dangerous as it grows. Its poison zones turn the fight into a positioning test.
↖ Main Threats
- Large health pool.
- Rapid movement.
- Poison puddles.
- Expanding body and hitbox.
- Restricted safe space.
↖ How to Beat the Pufferfish
- Use an upgraded SMG or another strong firearm.
- Maintain distance.
- Leave poison zones immediately.
- Move into open terrain before it expands.
- Avoid getting trapped against the grill.
- Heal before reaching critical health.
- Use full bursts only when your path is safe.
When the pufferfish starts expanding, stop chasing damage and reposition. Poison avoidance matters more than squeezing in one extra magazine.
Turn in the required boss item to unlock the next coordinates.
↖ Casino Village: Sniper, Tuna, Giant Bird, and Gambling
Casino Village offers high-value fish, stronger bait, the sniper rifle, and two progression bosses.
↖ Casino Village Priorities
1. Buy stronger bait.
2. Farm valuable fish.
3. Purchase the sniper rifle.
4. Hunt birds for cash and bonus kills.
5. Defeat the tuna boss.
6. Defeat the giant bird.
7. Turn in the required trophy for new coordinates.
↖ Is Gambling Worth It?
Gambling is not a reliable progression method. Stable boss farming is better.
| Approach | Recommendation | Reason |
|---|---|---|
| Bet cheap fish | Acceptable | Low-value risk |
| Bet rare fish | Avoid | Can erase valuable income |
| Bet boss trophies | Very risky | Only safe when bosses are easy to farm |
| Ignore gambling | Most efficient | Guarantees upgrade progress |
Sell valuable catches directly when saving for the sniper or assault rifle.
↖ Sniper Rifle Strategy
The sniper deals excellent single-shot damage and performs best against distant or flying targets.
| Strengths | Weaknesses |
|---|---|
| High single-shot damage | Weak at close range |
| Excellent against flying enemies | Slow fire rate |
| Can generate trickshot bonuses | Requires accurate aim |
| Strong for bird hunting | Poor panic weapon |
Use the sniper for birds and safe opening shots. Switch to the SMG when a fast enemy closes the distance.
Do not chase trickshot bonuses during dangerous boss phases. A small bonus is not worth losing the entire catch.
↖ Tuna Boss Strategy
The tuna is fast, aggressive, and awkward to fight in open ground. Buildings can restrict its movement.
↖ How to Beat the Tuna
1. Hook the tuna.
2. Move toward a nearby building.
3. Let it chase you around the structure.
4. Shoot while it is slowed, blocked, or stuck.
5. Use the sniper only at long range.
6. Switch to the SMG when it gets close.
7. Reload and heal whenever the building breaks line of sight.
This is not a clean duel. It is terrain abuse, and it works.
↖ Giant Bird Boss Strategy
The giant bird spends most of the fight airborne and drops dangerous projectiles. The sniper rifle is the best counter.
| Boss Action | Counter |
|---|---|
| Flying high | Track it with the sniper |
| Diving attack | Move sideways |
| Dropped projectiles | Fight near cover |
| Exploding on death | Watch where the loot lands |
| Flying over water | Lure it back over land |
Keep the fight over land. If the bird dies above the ocean, important drops may become difficult or impossible to recover.
Defeat it and turn in the required head or trophy to unlock Volcano Island.
↖ Volcano Island: Scientific Lures and Final Preparation
Volcano Island is the final progression area. Do not start the whale sequence until your assault rifle and food supply are ready.
↖ Volcano Island Checklist
1. Buy scientific lures.
2. Farm volcanic fish for money.
3. Purchase the assault rifle.
4. Upgrade bullet damage.
5. Upgrade magazine size and recoil control.
6. Stockpile snails, birds, and edible drops.
7. Prepare the bait required for the whale.
8. Defeat the normal whale.
9. Throw the whale into the volcano.
10. Defeat the mutated whale.
↖ Volcano Island Food
Use anything you can collect without spending Gold:
- Snails.
- Birds.
- Fish chunks.
- Edible creature drops.
- Boss summons that can be consumed.
Place or carry food before starting the final sequence. Searching for healing while the boss is attacking is how good attempts fall apart.
↖ Best Assault Rifle Upgrades
The assault rifle is the safest endgame weapon. It combines range, sustained damage, and enough accuracy for both whale fights.
| Upgrade | Priority | Reason |
|---|---|---|
| Bullet Damage | Very high | Shortens both whale fights |
| Extended Magazine | High | Reduces dangerous reloads |
| Recoil Control | High | Keeps sustained fire on target |
| Sight/Scope | Medium | Useful, but not essential |
| Cosmetics | Low | Save money for combat upgrades |
The whale's hitbox is enormous, so perfect accuracy is unnecessary. Sustained damage and safe reload timing matter more.
↖ Whale Boss Strategy
The normal whale looks worse than it is. With an upgraded assault rifle, the fight becomes a straightforward positioning check.
↖ How to Beat the Normal Whale
- Maintain medium range.
- Fire continuously during safe attack windows.
- Move away from ground-pound attacks.
- Keep the whale in view when it becomes airborne.
- Reload while it is moving or recovering.
- Heal before your health reaches the danger zone.
- Never attempt to melee it.
The whale's size works in your favor. Most assault-rifle bursts will connect.
For story progression, keep the whale for the volcano sequence instead of selling it. If the normal whale nearly kills you, stop and farm more upgrades before creating the mutated version.
↖ Mutated Whale Final Boss Strategy
The mutated whale is dangerous because burn damage continues draining health after the initial hit. Fire avoidance is more important than perfect DPS uptime.
↖ Final Boss Preparation
| Requirement | Recommended Level |
|---|---|
| Assault Rifle | Purchased |
| Bullet Damage | Maximum or near maximum |
| Magazine Upgrade | At least one level |
| Food | As much as you can carry or stage nearby |
| Snails/Birds | Stockpiled |
| Health and Hunger | Full |
| Escape Route | Planned before the fight |
↖ How to Beat the Mutated Whale
1. Drop the normal whale into the volcano.
2. Retreat immediately toward open ground.
3. Keep the mutated whale on-screen.
4. Avoid every visible fire zone.
5. Shoot during landings and recovery animations.
6. Reload while the boss is moving.
7. Heal immediately after taking burn damage.
8. Do not chase it uphill without a clear reason.
9. Maintain enough damage to beat the timer.
If you catch fire, stop shooting and recover. Continuing to attack while burning often turns a winning run into a death.
↖ Common Mutated Whale Mistakes
| Mistake | Why It Fails | Fix |
|---|---|---|
| Starting underprepared | Low DPS extends the fight | Upgrade AR damage first |
| Ignoring burn damage | Fire rapidly drains health | Heal immediately |
| Losing sight of the boss | Leads to surprise slams | Keep the camera raised |
| Carrying too little food | Prevents recovery | Stockpile snails and birds |
| Panic reloading | Wastes safe damage windows | Reload during boss movement |
Once the mutated whale dies, collect the final keys and use the last boat to complete the game.
↖ Best Gold-Making Methods by Island
Gold determines how quickly you can buy weapons and damage upgrades.
| Game Stage | Best Money Farm | Why It Works |
|---|---|---|
| Starter Island | Crabs and shrimp | Safe starting income |
| After buying the knife | First boss farming | Better payout |
| Swamp Island | Fish and piranha spawns | Enemies also provide food |
| Beach Island | Shark farming | Strong repeatable profit |
| Casino Village | Tuna and bird farming | High-value rewards |
| Volcano Island | Scientific lure fish | Valuable late-game catches |
| Endgame | Whale-related farming | Highest late-game value |
Prioritize consistency. If a boss kills you in half your attempts, drop down one tier and farm something safer.
↖ Best Weapons for Every Situation
| Situation | Best Weapon |
|---|---|
| Small, fast creatures | Knife or SMG |
| Enemy swarms | Shotgun |
| Flying enemies | Sniper |
| Large bosses | Assault rifle |
| Starter Island | Knife |
| Mid-game farming | SMG |
| Final bosses | Assault rifle |
The sniper is excellent against birds but poor when enemies reach melee range. The shotgun controls swarms but eventually falls behind upgraded automatic weapons. The assault rifle wins the endgame through reliable, sustained damage.
↖ Combat Rules That Prevent Most Deaths
- Fight inland, away from the water.
- Keep food in an easy-to-reach slot.
- Fill health and hunger before summoning a boss.
- Upgrade damage before cosmetics.
- Use trees, grills, and buildings as cover.
- Reload during boss movement or recovery.
- Watch the boss timer.
- Sell catches only after checking quest requirements.
- Stop using trickshots when the fight becomes dangerous.
- After two failed attempts, leave and upgrade.
Most unfair fights are equipment checks. More damage shortens the timer, reduces food consumption, and limits the number of attacks you must survive.
↖ FAQ
↖ What is the fastest way to make Gold in How to Fish?
Catch and sell basic creatures until you can buy the knife. After Swamp Island, switch to boss lures and repeatable boss farming. Sharks are a strong mid-game target, while scientific-lure catches and whale-related farming provide better late-game income.
↖ What weapons should I buy first?
Follow this progression:
Knife → Shotgun → SMG → Sniper → Assault Rifle
Use the knife for the starter boss, shotgun for piranha swarms, SMG for sharks and pufferfish, sniper for the giant bird, and assault rifle for both whale fights.
↖ What should I upgrade first on guns?
Upgrade bullet damage first. Then buy recoil control and magazine capacity. Damage produces the biggest immediate improvement because it shortens every boss fight.
↖ How do I beat the giant bird and tuna bosses?
Use the sniper rifle against the giant bird and fight it over land so its drops remain recoverable. Against the tuna, use buildings to slow or trap it, then attack with the SMG at close range.
↖ How do I beat the mutated whale?
Use a heavily upgraded assault rifle, enter with full health and hunger, and stockpile food. Retreat to open ground after starting the volcano sequence. Avoid fire zones, heal immediately after burn damage, and attack during the whale's landing and recovery windows.
↖ Summary
The fastest How to Fish progression depends on three things: free food, reliable boss farming, and timely weapon upgrades.
Use this weapon route:
- Knife for the beer can crab boss.
- Shotgun for the giant piranha and its swarm.
- SMG for shark farming and the pufferfish.
- Sniper for birds and long-range targets.
- Assault rifle for the whale and mutated whale.
Farm the strongest boss you can defeat consistently. Upgrade damage before moving to the next island. Keep quest items until you know they are safe to sell.
The final lesson is simple: cast the line, drag the monster inland, shoot it with increasingly excessive firepower, and sell what remains. That is fishing—more or less.
