Document Summary

Aquaculture is concerned with the eiciency of conversion of fee/food inputs into biomass. Semi-intensive- natural food producion simulated and/or complemented by inputs, such as, inorganic and organic ferilizers and supplemental feeds. Intensive aquaculture- no (or only very minor) contribuion of natural food. Convering exogenous feed resources into products (for a proit with min negaive impacts). The current switch from semi-intensive to intensive aquaculture means large increase in producion. The drive for personal proit big driver of intensiicaion. Species, life stage, rearing environment/producion system, socio-economical condiions, legislaions, restricions, customs, taboos. Results in the need for: -diferent feeds/foods ( type, composiions, quality) Algae and live natural prey" (can be diicult to produce in ariicial system) to feed infant stages (natural prey roifers, capepods, artemias) Graduated, uniformly sized, syntheic larval diets from 30-450 microns. Food: self-selected, natural, high degree of sanitaion (food grade) Feed: imposed, ariicial, lower degree of sanitaion (feed grade)
