Abstract

A detailed investigation was undertaken to study the growth and mortality characteristics of Nibea maculata off Thoothukudi
coast from July 2006 to June 2007. The growth parameters L∞, K and t0 were estimated as 26.78 cm, 0.810 and -0.204
respectively. The K value of N. maculata was relatively higher inferring faster growth rate of this tropical demersal fish
species. The estimated total instantaneous mortality co-efficient (Z) of N. maculata was 2.73 and the fishing mortality
co-efficient (F) was 1.06. The species is under-exploited in this region
