摘要
本文以1993~1996年烟台养马岛自然生长的紫彩血蛤(Nuttallia olivacea)为材料.对其肥满度进行了研究。结果表明:养马岛紫彩血蛤一年有1个肥满期,1个消瘦期。1~5月份较肥,肥满指数(1)为17.0~23.3,6~12月份较瘦,肥满指数(1)为13.2~15.3。二龄蛤肥满度最高。此外对三种肥满度的计算方法,判断繁殖期和确定采捕季节等进行了比较和讨论。
The meat condition of the natural Nuttallia olivacea in Yangma Island was studied in 1993 - 1996. The result shows that there is one peak period of meat condition every year. The peak period is in January to May, with the value of the index of meat condition (1) {IC(1)} ranging from 17. 0 to 23. 2. The period of lower level meat condition is in June to December, with the IC (1) from 13. 2 to 15. 3. The index of meat condition of the two-year-old clam is the greatest. Three calculative methods of meat condition judging the spawning period and determining the time of harvest have been compared and discussed.
