Quick answer: Complete the Fish Wing by working set by set, not by catching random shadows. Seasonal pond, river, and ocean sets are the best starting point; mine biomes, Deep Woods, multi-season, and legendary sets need separate routes.

Completion route
- Finish the current season’s pond, river, and ocean sets before the month ends.
- Catch multi-season fish while moving between seasonal targets rather than farming them separately.
- Revisit each unlocked mine biome with the elevator so biome fish do not compete with overworld time.
- Save Deep Woods and legendary targets for days when their access and weather conditions match.
- Donate immediately, then verify the set popup before selling duplicates.
Missed-fish diagnosis
If a target refuses to appear, check water type, season, weather, size, and whether the location has its own pool. The fish reference is optimized for that lookup; the fishing guide covers casting and route efficiency.
