| 摘 要： | 本文以１９９０－１９９３年烟台芝罘湾自然生长的长竹蛏为材料，对其肥满度进行了研究。研究结果表明：长竹蛏一年有一个肥满期，一个消瘦期。５月至１１月较肥，肥满指数（１）为５７．３－９３．７。１２月至翌年４月较瘦，肥满指数（１）为４７．２－５６．６。二龄蛏肥满度最高。由肥满指数推断，长竹蛏一年有一个繁殖期，为６月中旬至８月中旬。

| Abstract: | A study was made in 1990-1993 of the meat condition of the natural Solen strictus in Zhifu Bay. The study showed that there is one peak period of meat condition every year. The peak period is in May to Noyember, with the value of the index of condition (1) (IC(1)) ranging from 57.3 to 93.7. The period of lower level meat condition is in December to April, with the IC(1) from 42.7 to 56.6. The IC(1) of the two-year-old solen is the greatest. From the seasonal change of the degree of fatness it can be seen that there is one spawning period in a year.The spawning period is in the second ten days of June to the second ten days of August, peaking in the third ten days of June and in the first ten days of August. |
