The Grav Trap can be placed in an environment with an abundance of fish to act as a fish farm, although an Alien Containment tank is much more reliable.
The Grav Trap takes up 2×2 item slots in the player's Inventory. Although it requires a Battery to be built, it does not use energy. The Grav Trap attracts fish and any small item that can be picked up manually within reach. Plant material, such as Creepvine Seed Clusters, are the exception. It is best to place it on the ocean floor.
It is suggested to remove the objects caught by the Grav Trap before picking up the sphere. If the player is in the open ocean, currents may send the objects 30 meters or more away if the player picks up the Grav Trap with objects still attached it.
Spoiler alert: The following section contains story related material.
If placed beside an Alien Vent, the Grav Trap can provide near infinite food.
