Abstract

The length weight relationship and relative condition factor in Slaroides leptolepis is were studied for a period of one year (1987-'88) along Tuticorin coast. The calculated slope value for males, females and indeterminants, was found to be 2.6682, 2.5518 and 2.7026 respectively. The difference between the regression equation of males, females and indeterminantr, was found to be insignificant, and hence, a combined regression equation was calculated. The 'by value of the pooled fit was found to be significantly different from the cube law. Relative condition of the species was high during spawning season and was found correlated positively with Gonadosomatic Index and negatively with Gastrosomatic index.
