Length-weight relationship of fishes from an estuary of Abrolhos Bank, Brazil

Abstract: Aim We investigate the length-weight relationship estimates of seventeen species caught using an artisanal purse seine in Abrolhos Bank, a tropical estuarine complex eastern Brazil. Methods From February 2012 to November 2013, fish were collected monthly small with total 84 landings. The captured mangrove margins during high tide and retrieved after six hours at depths ranging from 1.2 3 meters. Results A 4433 specimens 17 nine families sampled. coefficient determination ranged 0.904 for Centropomus parallelus 0.987 Lutjanus cyanopterus. Species presented allometric growing, Caranx latus, cyanopterus M. curema exhibing negative while all other positive growing. present first data Brazil L. literature alexandrei. Conclusions Our results provide novel biological attributes species. By understanding relationships growth patterns these species, stock level may subside proper management initiatives such as fishing restrictions sites or seasons mesh size limits.
