| 摘 要： | 本文是浙江北部海区口虾站Ｏｒａｔｏｓｑｕｉｌｌａｏｒａｔｏｒｉａ（ＤｅＨｕａｎ）繁殖与摄食习性的研究结果。根据卵巢成熟系数、食物种类组成、摄食强度等的周年变化规律，结果认为：每年的３－５月是口虾蛄的成熟期；６－７月为产卵期。一年性成熟一次，卵巢成熟系数４月份最高；最小性成熟个体８０ｍｍ左右。口虾蛄为肉食性捕食动物，食性组成较杂，以鱼虾类为主。６月和１２月摄食强度最大，８月份摄食强度最小。

| Abstract: | The propagation and feeding habits of O .oratorla in Northern Zhejiang Sea Areas were studied in this paper,The results showed that O,oratoria matures in gonadS once a year,Its spawning itage is from june to july, the maximum ovary matur ing coefficient in Apr i l and minimum maturing size about 80 mm according to the yearly changes of ovary m aturing coefficients,food composit io ns and feeding quant it ies, etc. O. oratoria is a carnivorous predator with complicated food compositions,and feedS maindls on small fih and shrimp,The feeding quantity is maximum in June an Dyecember,resp-Ectioely,and minimum in Angust. |
