The Fish Basket can be placed anywhere on the ground, both on the surface and at the bottom of the sea.
To capture aquatic creatures, the Fish Basket has to be placed near them on the bottom of the ocean. The trap will be initializing the capture for a few seconds. When it's ready, you can capture the desired creature by quickly pressing E while looking at the Fish Basket.
Doing so will capture the creature and you will obtain a Filled Fish Basket, which spoils after 5 minutes which can be replenished by standing inside the water source. Placing the Filled Fish Basket down will release the captured creature. Some of the creatures that can be caught in the trap will be tamed upon release. Unlike most tameable creatures, their level is fixed from their spawn level, and as such, they can not obtain any experience.
Fish Baskets can also capture already tamed creatures, which will allow them to gain experience and it is also useful for carrying them to a different body of water.
