Large economies have been achieved in the production of food
fish with the use of larger systems and enhanced production
management strategies. These trends have also included use of
larger circular culture tanks because of their many advantages
for food fish production. Circular tanks make good culture
vessels because they can provide a uniform culture environment,
can be operated under a wide range of rotational velocities to
optimize fish health and condition, and can be used to rapidly
concentrate and remove settleable solids. However, the flow
inlet and outlet structures and fish grading and/or removal
mechanisms must be properly engineered to reduce the labor
requirement to handle fish and to obtain effective tank
rotational characteristics, mixing, and solids flushing. This
