Some Biological Aspects of Scallop Chlamys varia (Linnaeus, 1758) (Bivalvia: Pectinidae) from Aegean Sea coast of Turkey

Abstract

This research has been carried out to investigating of some biological aspects of scallop, Chlamys varia distributing in Gulf of Gerence (Aegean Sea), June 2011 – December 2012. A total of 326 samples were collected, 86 (26%) female, 94 (29%) male and 146 (45%) were immature. Height and weight of the samples varied between 30.98 – 63.12 cm (50.68 ± 6.03) total height and 3.34 – 28.19 g (16.20 ± 4.74), respectively. The size and dry weight frequency distribution and height – dry weight relationships for each sex of the scallop were studied. The relation between height (H) and dry weight (W) was determined as W = 0.0004H 2.701 (r2 = 0.903). This was calculated for females as W = 0.0005H2.660 (r2= 0.937), and for males W = 0.0002H2.848 (r2= 0.954). The regressions of dry weight – height, dry weight – breadth were computed allometric; breadth – height and thickness – hight were found linear relationship.
