FAQ

How much does cooking increase fish value?
Current independent guides agree that cooking can raise a catch to a maximum 1.5x sale value. Remove it at the cap. Leaving it over the heat longer moves it toward a burnt state instead of creating a larger multiplier.
How do you unlock the grill in How to Fish?
The grill opens on the Desert, the third island, through the Blue Shark-related quest chain. Sources differ on the exact NPC sequencing, so follow the live quest text and preserve the shark or required drop until the grill activates.
Can you cook boss fish?
A physical catch may fit on the grill, but unique bosses and setup catches often have a quest role. Never cook a trophy, Tuna, or unusual body until its hand-in is finished. The 1.5x sale bonus is safest on replaceable ordinary catches.

How do you cook fish for more money?

Place one ordinary sale catch over the active grill and watch its value rise. Remove it immediately when the meter reaches 1.5x, the maximum supported multiplier. Cooking past the cap does not create a better sale; it moves the catch toward burnt, where the value bonus is lost and an achievement-related food state begins.

The grill is a predictable part of the published money-making loop: catch, finish with a controlled Killscore bonus, cook to 1.5x, then sell. It is not a reason to risk a unique story object.

How do you unlock the grill?

Reach the Desert / Island 3 and complete the Blue Shark-related local quest. Multiple current guides agree on the island and creature, and the official Grillmaster achievement confirms that the grill has an activation state. The exact order of NPC dialogue and hand-ins differs between guides, so that fine detail remains Pending verification (待核实).

Use this safe sequence:

  1. Speak to the Desert NPCs before catching optional minibosses.
  2. Obtain the Standard Boss Lure used for the Blue Shark route.
  3. Catch and defeat the Blue Shark.
  4. Keep the body or distinctive drop until the relevant NPC accepts it.
  5. Confirm the grill starts and Grillmaster unlocks.

If the live quest requests a different named object, follow the game rather than forcing an outdated guide step. The beginner walkthrough places this side route beside the required Pufferfish chain.

Why is 1.5x the stopping point?

Current All Things How and Mobalytics guides independently report the same 1.5x cooking cap. The value increase is therefore useful but bounded: a $100 raw catch can become $150, not an unlimited multiplier. Once the display reaches the cap, every extra moment adds risk without adding verified value.

Raw valueValue at 1.5xExtra value from cooking
$20$30$10
$100$150$50
$500$750$250
$1,000$1,500$500

These examples apply the multiplier mathematically; they are not claims that a particular fish has that base price. Exact creature prices can change by patch and Killscore state.

How do you avoid burning a valuable catch?

Cook one valuable item at a time, stand close enough to read its state, and remove it at 1.5x before doing inventory or co-op work. Assign one player to the grill during group runs. If a distraction matters more than the catch, remove the fish early and accept a smaller bonus instead of risking the burnt state.

The safest routine is:

  • Clear loose bodies away from the heat before starting.
  • Put only a replaceable sale catch on the grill.
  • Watch the catch rather than the next fishing cast.
  • Lift it at the 1.5x cap.
  • Move the cooked catch to a separate sale pile.
  • Sell before beginning a dangerous boss setup.

The rare-fish locations guide identifies targets that should be checked against Fishipedia or quest needs before they become dinner.

Which catches should never go on the grill yet?

Keep every distinctive trophy, custom-bait result, or encounter setup fish raw until the associated NPC chain is complete. The most important example is Tuna, which current boss guides use to summon the Albatross. Boss remains also commonly serve as the proof that unlocks a boat or coordinates.

Catch or itemWhy to protect it
Spider Crab remainsBoat Keys hand-in
Giant Piranha skeleton/trophyForest progression hand-in
TunaAlbatross encounter setup
Albatross or whale quest dropLate-story progression
Unidentified rare variantFishipedia/collection confirmation

If an item has a unique name or model, separate it from the cooking pile until the quest log no longer refers to it. The boss guide explains the encounter dependencies.

How do you unlock the cooking achievements?

Three official achievements are directly related to cooking. Grillmaster requires starting the grill, Dinnertime requires bringing dinner to the woman in the Forest, and Yummy in my tummy requires eating a burnt creature. Complete the burnt-food experiment on a cheap, replaceable catch rather than a valuable rare fish.

AchievementOfficial requirementEfficient route
GrillmasterStart the grillComplete the Desert grill quest
DinnertimeCatch dinner for the lady in the ForestRevisit after cooking is available and follow her request
Yummy in my tummyEat a burnt creatureDeliberately burn one low-value ordinary catch and consume it

The official wording for Dinnertime does not specify every preparation detail on the public achievement page. Follow the Forest NPC request in the live version rather than assuming any cooked fish will work.

What if a weapon or tool gets cooked?

Multiple current secondary guides report that cooked or dirty weapons and tools can be cleaned by dipping them in water. A stable direct developer note for the claimed Patch 1.0.10 attribution was not available in the accessible Steam index, so the exact patch attribution remains Pending verification (待核实). Test the behavior with a low-value tool before relying on it.

This reported cleanup is not a way to restore a burnt fish’s sale value. Move equipment away from the grill before placing bodies so an accident does not interrupt a timed cooking cycle.

Is cooking always worth the time?

Cooking is most valuable on high-base-value catches when the grill is already on the route. It is less useful if transport, boss danger, or co-op confusion makes burning likely. A 50% gain is strong, but a lost quest item or destroyed high-value catch costs more than selling safely at base value.

Use the grill when:

  • the catch is ordinary and replaceable;
  • the sale point is nearby;
  • someone can watch the meter;
  • the added value exceeds the time and risk;
  • the team has already secured required quest drops.

Skip or delay it when a boss is active, inventory ownership is unclear, or the live quest may need the body.

Where was the cooking system verified?

Official achievements confirm the grill, Forest dinner, and burnt-food interactions. Three independent guides agree on the Desert route and cooking behavior, while two separately state the 1.5x cap. Conflicting NPC-order and cleanup-patch details remain marked instead of being combined into a false sequence.
