PRESENT STATUS OF COSTAL AQUACULTURE IN BRASIL

Resumo

Coastal aquaculture in Brasil is concentrated on the rearing of finfishes (mullets, snooks and mojarras), crustaceans and molluscs.

Most of the papers reviewed brings only preliminary results. However, good results are being achieved with the polyculture of the mullet Mugil curema, associated with the snook Centropomus undecimalis, and mojarras Diapterus olisthostomus, D. brasilianus and D. rhombeus, yielding about 1,300 kg/ha/year with artificial feeding. Similar type of culture with the mullet M. liza and the snook C. undecimalis yielded about 1,500 kg/ha/year.

The stockings of the fishponds are made with young fishes. The hypophysation method, which was started in Brasil, is not yet being used in coastal aquaculture.

Culture of shrimps Penaeus brasiliensis, P. paulensis and P. monodon is in progress.

Good concentrations of mussels Perna perna and Mytella falcata, and oysters. Crassostrea brasiliana and C. rhizophorae are found in some areas, but there is no commercial culture. The Pacific oyster Crassostrea gigas was recently introduced In southern Brazil.
