Length-weight relationship of 73 fish species caught in the southeastern inner continental shelf region of Brazil

The a and b parameters of the length-weight relationship (LWR) of the form W = aLb were estimated for 71 species of Actinopterygii and 2 Elasmobranchii, caught in the coastal region and inner shelf of southeastern Brazil. Estimates of b varied from 2.151 to 3.882. For the first time LWR for eight fi...
