ABSTRACT
Aquaculture - raising marine or freshwater animals and plants in controlled environments - has been suggested as one partial solution to world food problems. The introduction of aquaculture could take labor and capital away from traditional activities which have made productive contributions to communities. Aquaculture would supplement, not replace traditional food, and a smaller part of the population would be involved in production. Aquaculture has the potential to provide more protein, provide acceptable food calories, and to change the availability of protein for some segments of the population. Regardless of the physical setting, aquaculture production requires nutrients, good water quality, and a means for eliminating or controlling predators and disease. Aquaculture may compete with other production systems on several levels. Aquaculture may compete with agriculture and capture fisheries. Aquaculture is constrained by local, regional, and national laws and customs. Aquaculture projects may be designed to provide direct profits for either a private owner or for the community.
