Length-weight relationship and other dimensional relationships of Metapenaeus monoceros (Fabricius) from the Kakinada coast

Abstract

Metapenaeus monoceros are significantly different in both males and females. The equations are: Males : Log total weight =-5.0895+ 2.9521 log total length Females : Log total weight = -5.4649 4 3.1509 log total length Males : Log tail weight = -5.4132 4- 3.0214 log total length Females : Log tail weight — -5.8117 4- 3.2294 log total length The relationship between total length and carapace length vary between juveniles and adults in both the sexes. The equations are: Males (juveniles) : CL = - 0.2157 I 0.2166 TL Females (juveniles) : CL = - 1.9900 + 0.2407 TL Males (adults) : CL = -10.1696 4- 0.3109 TL Females (adults) : CL = -13.4473 4- 0.3411 TL The relationship between total weight and tail weight is not significantly different in males and females. The common equation for both the sexes is: Tail weight = 0.3260 + 0.7036 total weight A conversion table for total weight to tail weight and vice versa is presented.
