More people are interested in fishing than nature can support. The lakes or rivers where fish are stocked either do not have the individual species, or the systems cannot support adequate reproduction to meet the demand of sportfishermen. Through aquaculture, the angler could be provided with a recreational outlet that may not have been available otherwise. Aquaculture efforts can also be used to save or restore an endangered or threatened species. These are special situations where, for various reasons, fish cannot reproduce in sufficient numbers, or the progeny do not survive well enough to maintain themselves as a population.
Results indicate that conservation efforts are having a positive impact.
Pond culture, for example, will require more water than tank culture, in which the water is recycled. Location Location of your operation is crucial from the perspective of the availability of water, terrain, temperature, soils, protection from the environment, such as storms in coastal areas, and other factors. If public waters are being leased, you need access to both the bottom and the water column, that region between the surface and bottom. This is especially important with open water culture such as shellfish or netpen fish culture. Ideally, location should also be close to processors and markets.
