Abstract

Highlights

Este trabalho apresenta a relação peso-comprimento de 25 espécies de peixes
Length-weight relationship studies are used in fishery biology and in fish management because they permit weight estimates from length data and vice versa (Froese, 2006), comparison of spatial and temporal differences between populations or species, and determination of the condition factor (Viana et al, 2004)
The parameters of this relationship vary according to sex, body size, time and space, and variations in the population structure, food availability and fishery pressure may result in different length-weight relationships for the same species (Giacalone et al, 2010)

Summary

Introduction

Este trabalho apresenta a relação peso-comprimento de 25 espécies de peixes. As coletas foram realizadas mensalmente de 2010 a 2011, utilizando redes de arrasto em estuários do rio Cricaré, Espírito Santo, Brasil. Length-weight relationship studies are used in fishery biology and in fish management because they permit weight estimates from length data and vice versa (Froese, 2006), comparison of spatial and temporal differences between populations or species, and determination of the condition factor (Viana et al, 2004). The parameters of this relationship (a and b) vary according to sex, body size, time and space, and variations in the population structure, food availability and fishery pressure may result in different length-weight relationships for the same species (Giacalone et al, 2010). Considering the differences between the two estuaries, the objective of the present study was to identify possible changes in the relationship between length and weight of analyzed fish
