Island Fish Tycoon

Turn a quiet tropical island into a thriving fish farm in Island Fish Tycoon — a cozy, laid-back tycoon game you can play completely offline. No internet, no login, no timers nagging you. Just you, your ponds, and the sea.

🎣 CATCH & DISCOVER
Cast a line at the lake and the sea to discover 37 unique species — from tiny guppies and neon tetras to mighty tuna, swordfish, and legendary living fossils like the coelacanth and sturgeon. Each fish is sized to life, so a goldfish really is a tidy little thing next to a giant gar.

🐟 BREED & GROW
Find a rare fish carrying roe and you can start farming it in your own ponds. Freshwater or saltwater, keep the water clean, feed your stock, and watch your ponds fill up ready for harvest.

🚢 SELL & EXPAND
Harvest into your warehouse, and let the boat carry your catch to market. Reinvest your coins to unlock new buildings one at a time — the Tackle Shop for better gear, the Notice Board for quests, the Hatchery, cozy Lodging for passive income, and the Lab for permanent upgrades.

🏝️ BUILD YOUR ISLAND
Grow from a single pond into a booming fishery empire. Hand-painted isometric art, a warm tropical soundtrack, and a gentle sense of progress make it the perfect game to relax with.
