Build a Zoo is a tycoon-style experience that lets you manage a sanctuary for both land and sea creatures. While eggs for hatching animals are readily available on the conveyor belt, those for acquiring fish need to be reeled in from the sea. The process for getting marine life into the zoo is straightforward, but it demands a hefty sum of money from beginners.
Here's how you can unlock fishing to begin collecting rare sea creatures in Roblox Build a Zoo.
Unlocking fishing in Build a Zoo

To unlock fishing, you'll need to access the zone beyond the conveyor belt. The entry to this area will be blocked by iron chains, which will disappear once you spend 5000 Coins to unlock it.
Coins for making in-game purchases and unlocks are naturally given by creatures in your zoo. You simply need to approach an animal or fish to collect its earnings, which also generate the currency while you're offline. Rarer creatures give more money per second in the game.
Once you unlock the zone, a fishing rod will be added to your hotbar. You can then approach the waters, cast the rod, and reel in fish eggs. Note that such an egg will also have a hatch time, which appears on top of it once you place the item in one of your slots in the zoo.
Here are the names of a few eggs that can be acquired by fishing:
- Seaweed Egg: Contains Anglefish, Bighead, Butterflyfish, and Needlefish
- Clownfish Egg: Contains Butterflyfish, Needlefish, Hairtail, and more
- Lionfish Egg: Contains Needlefish, Hairtail, and more
- Shark Egg: Contains Catfish, Flounder, and more
Unlike the animal eggs, which need to be purchased with Coins, there is no cost associated with the fish eggs. This makes fishing a useful mechanic for new players who quickly want to get more creatures and earn money.
Redemption codes offer a shortcut for getting Coins. Use our guide on the latest Build a Zoo codes to amass the currency, and then buy eggs or upgrade the conveyor belt.
