Abstract
Nowadays, larviculture is one of the main obstacle in aquaculture. Live food availability, particularly zooplankton, is essential to development of young fishes and crustaceans. Nevertheless, there are serious difficult to obtain zooplanktonic biomass enough to attend the growing world demand. The neotropical freshwater Anostraca Dendrocephalus brasiliensis has a great potential for utilization in Brazilian aquaculture due to its size (25mm), easy culturing and great attractiveness for fishes. So, the present project aims to investigate ecological and physiological aspects of this species, at natural and experimental environments, in order to subside the development of technologies to produce resistance eggs and biomass for utilization in aquaculture. Its productive potential will be evaluated through studies of secondary production (ecological and physiological approach), growth rates, energetic balance, trophic efficiencies, life history characteristics, fecundity, egg viability, number of generations, longevity under different environmental and food conditions, body length and biomass. It will be performed studies on fish´s food preference and nutritional values of D. brasiliensis compared to other zooplanktonic species, as well as the impact of each one in the production of cultivated neotropical fishes. To optimize D. brasiliensis culturing, it will be investigated the influence of microalgae nutritional quality on the animal biochemical composition (proteins, lipids and carbohydrates). Competition, predation and grazing interactions will be also investigated in order to found the real impact of this species on the other freshwater planktonic populations, mainly in São Paulo State.
