[0021] The fish collection process is completed by utilizing a circulating water pump, a water pipe, and a fish outlet located at the same height as the aquaculture platform, and gravity is used to transport the fish to the live water boat. During this process, the fish are always in the water, reducing damage to the fish due to dehydration, lack of oxygen, physical squeezing or other reasons, thereby ensuring the quality of the fish and reducing the economic losses of the aquaculture owners.
