Good circulation of pond water through cages helps remove metabolic wastes. There are several disadvantages to holding fish in cages. Locating cages away from shore allows for better water circulation but necessitates the use of a boat or a pier out to the cages. Dipping fish out of a cage from a boat or pier can be difficult, particularly if large or heavy cages are used. Any off-flavor problems in the pond will affect caged fish as well, postponing sales indefinitely.
Caged fish are also more susceptible to disease problems.
Direct sales of live fish is possible only if the fish stay alive. Transferring fish from production ponds to holding facilities or hauling tanks is stressful to the fish. Care must be taken to avoid abrupt changes in water temperature or water quality. If the difference in water temperature is greater than 5 degrees Fahrenheit, water should be changed gradually to allow the fish time to adjust. Holding in Tanks Fish can be held in tanks if they are to be sold over a two to three day period.
