Relação peso-comprimento da corvina Micropogonias furnieri (Desmarest) (Pisces, Sciaenidae) na Baía de Sepetiba, Rio de Janeiro

Length-weight relationship of white croaker Micropogonias furnieri (Desmarest) in the Sepetiba Bay, Rio de Janeiro

Resumo

The length-weight relationship of populations of white croaker Micropogonias furnieri (Desmarest, 1823) in the Sepetiba Bay (22º54'-23º04'S; 43º34'-44º10'W), were assessed. It aims to contribute to the knowledge of the biometrics and to estimate the biomass of this very abundant fishery resource in the Bay. Fishes sampled, in both trawling beach seine, sampling programme, from October 1998 to May 1999 were analyzed. The equation found was W = 0.00000942 L2.99 fom the natural logaritmized transformation of the raw data, through ordinary least square equation = In W = -11.57 + 2.996 In L (r=0.99). The condition factor was relatively high compared with coastal population from Southeast Brazil, probably due to in this study both males and females from juvenile and adult were considered, while in coastal areas, only adult female were analyzed. The alometry coefficient (θ), on the other hand, is very similar to the coastal Southeast Brazil population, but differed from Northeast and South Brazil populations.

ABSTRACT

The length-weight relationship of populations of white croaker Micropogonias furnieri (Desmarest, 1823) in the Sepetiba Bay (22º54'-23º04'S; 43º34'-44º10'W), were assessed. It aims to contribute to the knowledge of the biometrics and to estimate the biomass of this very abundant fishery resource in the Bay. Fishes sampled, in both trawling beach seine, sampling programme, from October 1998 to May 1999 were analyzed. The equation found was W = 0.00000942 L2.99 fom the natural logaritmized transformation of the raw data, through ordinary least square equation = In W = -11.57 + 2.996 In L (r=0.99). The condition factor was relatively high compared with coastal population from Southeast Brazil, probably due to in this study both males and females from juvenile and adult were considered, while in coastal areas, only adult female were analyzed. The alometry coefficient (θ), on the other hand, is very similar to the coastal Southeast Brazil population, but differed from Northeast and South Brazil populations.
