Abstract
This study attempted to describe the length and weight frequency, and length-weight relationship in the black sea urchin, Stomopneustes variolaris, in Sri Lanka. The sampling sites Mount-Lavinia (n=43), Beruwala (n=99) and Tangalle (n=55) were selected from South-west coast in Sri Lanka. The shell length and body weight were measured separately for three sampling sites. The mean length and weight of S. variolaris were 5.55±1.04 cm, 101.40±57.76 g; 6.54±0.86 cm, 147.90±50.40 g, and 6.41±1.05 cm, 150.50±59.45 for Mount-Lavinia, Beruwala and Tangalle, respectively. In addition, the length-weight relationship of S. variolaris were W=0.9953*L2.6472, W=0.9651*L2.6536 and W=1.4665*L2.4637 for Mount-Lavinia, Beruwala and Tangalle, respectively.
