摘要
本文以1984—1985年在胶州湾养殖的海湾扇贝为材料进行了肥满度的研究。肥满度以干贝指数I.A.与干内脏指数I.V.表示。研究结果表明:I.A.一年有春、秋两个高峰,指数值达5以上的时间主要在中秋—冬季,最高达6以上;一龄贝的I.A.比二龄者大约1/4。I.V.的变动态势与I.A.大致相似,但略迟于后者。I.V.超过5的高峰期为4月末—6月上旬及9—10月。肉柱得率以10月—翌年4月期间较高,达10％以上,其中11月达13％以上。内脏得率一般在20％以上,临界生殖时达30％以上。从I.A.判断,胶州湾海湾扇贝的最佳收获期为养殖当年的11—12月。从I.V.判断,春季生殖期为5月中旬—7月中旬,盛期为6月,秋季者为9—10月,盛期为9月。
This paper presents the results of a study on the meat condition of the bay scallop, Argo-pecten irradians Lamarck, cultivated in Jiaozhou Bay, Shandong Province in 1984-1985. The peak over 5 periods of I. V. index of the dried viscera is in spring from late April to early June and in Fall from September to October, decreasing to 3 or 4 in late June to early August and fluctuating from November to next March. The variation of I. A. is similar to that of I. V. but takes place slightly earlier than the later. The I. A. of one-year-old bay scallops is about 1/4 greater than that of two-year-old scallops. The higher level adductor muscle gain is in October to next April, highest (13%) in November. It is generally lower than 7 from June to August. The viscera gain usually exceeds 20% and even over 30% in the spawning period, which occurs twice a year in Jiaozhou Bay, one in spring, peaking in June, another in Fall, peaking in September
