The sciaenid fishery and some biological aspects of Johnius carutta from Madras.

E. Vivekanandan
Abstract

The annual fluctuations in the sciaenid fish landings from mechanised trawlers in Madras during 1980-1984 are related to the effort. The maximum landings is during January. The dominant species Johnius carutta, matures at 140 mm total length and the major spawning season is June - July. The length-weight relationship can be described by the equation log W = — 4.4063 + 2.7990 log L. The von Bertalanffy parameters of growth are estimated as K = 0.726; to = 0.281 and Loo = 259 mm.
