| 内容記述 | To determine the effective use of a new standard body length (Le) of Apostichopus japonicus, intertidal line-transect survey and subtidal diving survey were carried out. The Le is the estimated value of La (anesthetized body length) and can be calculated from body length and body breadth according to the regression formula without anesthesia. Here we simultaneously used Le and the conventional body length (L) to clarify the structure of the natural population, and compared the results by using Le and L. L were measured while animals freely extended and contracted. It was found that there is a trend that the body size was underestimated using L for middle - large sized animals (over 100 mm at Le), which generally showed strong body contractions. The analysis of polymodal frequency distribution into normal distributions shows that, all of the means of the Gaussian distributions adapted for L were smaller than that of Le. Further, L of large sized animals tended to be markedly lower than Le. Thus the growth curve calculated from L underestimated the rate of growth. | |||||
