It is known to grow and farm marine animals on land in aquaculture tanks. A typical aquaculture system may include a plurality of stand-alone tanks which may be coupled to a water filtration system. Generally, marine animals of different size are held in different tanks and as the animals grow they are moved from tank to tank until they reach a size where they are ready for the market. The limit on the number of marine animals that can be held in any particular tank is largely dependent on the ability to maintain the water quality by removal of debris (such as feces and uneaten food) from the tank as well as the removal of algae or other growths from the wall of the tank. Currently the only effective method to fully and properly clean the tank is to completely drain it of water and get inside the tank to scrub down its walls and clear away any debris. While the tanks are sometimes connected with water filtration systems, these systems are generally unable to prevent the build up of foreign matter on the bottom of the tank.
When a tank is being cleaned, the marine animals previously held that tank need to be transfered to a holding tank. The current method of doing this is to simply use nets or scoops to catch the fish and physically transfer them to a holding tank.
