Abstract
The allometric studies were made for standard length-brain length (SL-BL), standard length-brain weight (SL-BRW) and brain length-brain weight (BRL-BRW) relationships in Etroplus suratensis, a teleost, Regression coefficients for SL-BL relationship in males is 0.1197 and 0.0675 in females. While SL-BRW relationship in E. suratensis, the regression coefficient for males and females the same and a combined regression line is formed. In BRL-BRW relationship regression coefficient is 0.0276 in males and 0.0502 in females. Thus in the twO relationship the males having higher growth rate than females.
