Cages and Net-Pens:
Culture cages and net pens are structures placed in a natural environment and stocked
with fish for growout. The only real difference between the two is size. Cages tend to
be relatively small (a typical cage has a volume of 1 or 2 m2), while net-pens are of-
ten several meters on a side and 10 to 20 meters deep. Cage culture has been prac-
ticed to a limited extent by catfish farmers. For example, in Arkansas (where leasing
of state lakes for cage culture operations is possible ), catfish have been commercially
produced in cages. Cages have also been used by researchers. Most cage culture is
conducted in freshwater environment, while net-pens are most commonly used in the
marine environment. Net pen culture has been restricted to protected waters, but re-
cently, net pen engineering has advanced to the stage that open sea pens are now
available that can withstand storms without damage.
