|
In order to investigate the appropriate processing season of ark shell(Scapharca subcrenata) cultured at the south coast of Korea, the edible portions were determined for coefficient of fatness and yield of edible portion using specimens collected bimonthly from December 1994 to December 1995. The relationship between shell length(X) and total weight(Y) of S. subcrenata is shown as follows; Y=0.001608X^(2.5199). The relationship between total weight(X) and meat weight(Y) of S. subcrenata is shown as follows; Y=0.3594X-0.5566(r=0.99). The relationship between total weight(X) and meat weight(Y) of S. subcrenata is shown as follows; Y=67.1647X+20.6370(r=0.99). The coefficient of fatness and yield of edible portion showed a marked bimonthly variation with a maximum in December and a minimum in August. The appropriate processing season of S. subcrenata would be in winter and spring, and not in summer and autumn season, the spawning season of the S. subcrenata.
