[Problems and outlook for animal production in the aquatic environment].
The major source of aquatic animal production is based on fisheries. Currently, a significant portion of the fishery resources is used for non-food purposes. One of the first steps towards rational exploitation of the natural fishery resources should be to limit such abuse and address the needs of an increasing global population. The challenge for the fishery industry is to develop methods for early and reliable prediction of stock availability and fluctuations in order to maintain a sustainable supply. With the continuing decline in fishery resources, aquaculture is slowly becoming an interesting alternative for the supply of animal protein of high nutritional value. Aquaculture, like any other human activity can have adverse effects on the environment. In this context, the semi-intensive farming systems prevailing in the tropical areas should be encouraged, substantiating them with scientific knowledge on the nutrient flow in such confined ecosystems. In some instances of intensive culture systems, progress has been made in aquaculture waste management by applying adequate nutritional strategies. Such an approach should be extended to other cultured species. Be it production for profit or production for food, sustainable aquatic animal production is intimately connected with all human activities, in as much as all these activities invariably have an effect on water quality. Hence, greater consideration is needed towards a general strategy of protecting the aquatic ecosystem at all levels.
