How to Fish links island progression to quests and bosses. The reusable route is to speak with the local task character, supply the required catch or bait, defeat the boss, preserve its trophy, return the item, and check travel for the next unlocked route. A complete official island list is not available in the sources reviewed here.

The direct answer about island progression

The Steam store confirms that quests and boss fights unlock additional islands. Community footage supplies a working example in which a local fish request leads to carrot bait, Pufferfish, a tail trophy, and continued progression. Use that sequence as a model, not as proof that every island requests the same items.

Pending confirmation: the full island count, official name of every location, exact ordering, travel prices, and all local task requirements. The live travel interface is the strongest authority for your current save. Record what it shows rather than forcing an outside numbering scheme.

The official quest-and-boss unlock loop

Begin each area by finding the character or prompt that defines the local task. Preserve the requested item and any reward that looks like bait. Start the boss only after the quest state and team ownership are clear.

After the fight, treat the trophy as a progress item. Return it before selling, collecting, or gambling other unusual results. Then reopen travel and confirm that the next route is genuinely unlocked.

A reusable task-to-trophy island template

Capture six fields for each island: displayed name, local character, requested catch, boss trigger, trophy, and unlocked destination. Add the patch version and whether the run was solo or co-op. This creates a database from visible evidence instead of copied assumptions.

If a field is unknown, leave it pending. Do not use a familiar creature model as proof of an item name. Do not label an island third or final unless the current route or official note supplies that relationship.

Patch 1.0.5 and locked-island travel

Patch 1.0.5 fixed an exploit that allowed travel to a locked island. That official note confirms that normal progression includes enforced route locks. Reaching land through an exploit should not be documented as a legitimate unlock method.

If a route appears unavailable after a trophy hand-in, recheck the task state and patch version. Avoid reproducing an old shortcut from launch footage. A fixed exploit may leave a player stranded or skip necessary progression data.

Patch 1.0.4 and the final-island path

Patch 1.0.4 made the path on the final island easier. This confirms a final-area concept in the official notes, but it does not publish the complete preceding roster. It also shows that route difficulty and geometry can change.

Use current visual landmarks and travel labels instead of undated directions. A screenshot from before the patch may show a harder or different route. Mark any guide path with the version that was actually tested.

What the first-hour transcript adds

The beginner footage shows why local task order matters. It also warns that trophies are not ordinary sale items and that catches can be stolen if left exposed. These operational details connect combat success to actual progression.

In co-op, choose a task-item carrier before fishing and a trophy carrier before the boss ends. Confirm each participant's travel state afterward. Larger lobbies make coordination more important, not less.

Island names and complete roster pending confirmation

Pending confirmation remains necessary because the reviewed official pages do not expose a full map. Community search demand can reveal which routes confuse players, but it cannot certify every name or order. A complete roster should wait for a systematic capture of the live travel interface.

Until then, use the quest-to-trophy template and official news. It provides a safe progression method without invented map labels. When future evidence is added, each island entry should include a reviewed date and direct source.

A complete map audit should capture the travel interface before and after every trophy hand-in. Record locked destinations as locked rather than assigning them guessed positions. This makes route changes visible and prevents an exploit or co-op state from being mistaken for the standard island order.

Keep the captured save state and patch date with the map evidence.
