Abstract

Length-weight relationship of the white-spotted rabbitfish Siganus canaliculatus(Park, 1797)were taken in fresh condition separately for male, female and indeterminants from the Gulf of Mannar region. Analysis of covariance revealed highly significant difference (P<0.05) in the length and weight relationship between both the sexes and indeterminants. Hence,three different logarithmic equations were derived viz., i) Males: log W = -5.0218 + 3.0304 log L; ii) Females: log W = -5.8008 + 3.3990 log L and iii)determinants: log W = -4.1916 +2.6410 log L. The value of regression coefficient 3.03 and 3.39 was obtained for males and females respectively and 2.64 for indeterminants that departed from the cubic value, 3 at 5%level.
