In an intensive culture system, such as trout or catfish production, growth rate could be more of a concern than efficiency in the use of water space and nutrients. Polyculture increases the total aquatic production in a volume of water by using species that occupy different dimensions of the water and feed on different feedstuffs. Aquaculture crowds species that are not used to crowding. Crowding increases the productivity of a space while increasing management for the space. Aquatic species selected for culture exhibit adaptability to withstand crowding.

Excretory System Life processes produce waste products. The excretory system eliminates wastes from the body. Typically, it consists of the kidneys, urinary ducts, urinary bladder, and urinary opening. Kidneys filter wastes from the blood. The urinary bladder holds these wastes until they are excreted through the urinary opening. Respiratory System The respiratory system takes in oxygen from the environment, delivers it to the tissues and cells of the body, and picks up carbon dioxide from the tissues and cells, delivering it to the environment.
