Analysis of Length and Weight Characteristics of Green Mussel, Perna viridis, from Thailand

Abstract

The following parameters were measured (females and males separately) in 1,760 individuals of the green mussel, Perna viridis (Mytilidae): size (length, height), weight (total, flesh + shell, shell. Flesh, wet, flesh dry). Size/weight relationships were determined as well as the relationships within various weight units. The analysis suggests that the weight unit "flesh + shell" should be used as a standard unit for total weight. With this unit taken as weight, the exponent "b" of the size/weight relationship varies between 2.55 and 2.87, depending whether "length" or "height" is used as dimension unit. The sex ratio in the sample was 44% male to 56% female. Sexual growth dimorphism was not observed.
