Resumo em Inglês:

Although mullets from the Brazilian coast have been commercially ex-ploited for a long time and used in fish culture experiments more recently, data for accurate identification of species are not available in the Brazilian literature. This guide was planned to provide Information for the identification of ali the species found along the Brazilian coast, based on inspection of easily recognizable morphological features. A key to species and data on their distribution, fishery, biology and fish culture in Brazil are presented.

Resumo em Inglês:

To provide better cond’tions for fish culture, a study was undertaken to assess the best way of adapting mullet fingerlings (Mugil curema) to jreshwater. Mullets have been submitted to direct shock and gradual decrease of salinities of 12‰, 7‰, 3‰ and 2‰ (freshwater), with a survival varying from 65% to 100%. It was observed that weight varies in function of time, at salinities of 0,2‰, 3‰ and 7‰, and that of the fish médium with values of 14‰ and 30‰ (winter and summer) at Tamandaré, and 18‰ and 31‰ (winter and summer) at Itamarac‡, located res-pectively at the south and north of the state of Pernambuco coast.
