- [2026-08-01] New Breeding Basin for the warehouse: put in two caught fish of the same species plus a byproduct as feed, and the pair breeds hatchlings of that species over time
- [2026-08-01] Hatchlings from the Breeding Basin carry a quality bonus that only counts in the Fish Factory, so they are worth more when processed and exported
- [2026-08-01] Only Common, Uncommon and Rare fish can be bred, and bred fish never count towards records or the leaderboard
- [2026-08-01] Breeding Basin hatchlings now inherit their size from both parents, so breeding your biggest fish gives reliably big offspring
- [2026-08-01] A Tier 3 Breeding Basin drops its hatchlings straight into a free Fish Tank, so Factory Plans can pick them up automatically
