摘要
本文根据1990年2～11月在三沙湾海域分别进行4个季节调查的资料,对三沙湾鱼卵和仔、稚鱼的种类组成、丰度和主要种类的分布进行研究和探讨.结果表明,本海区共出现鱼卵和仔、稚鱼26种,分别隶属于17科22属.在数量上,鱼卵最高值出现在春季（5月）,其中鱼卵丰度较高的种类是真鲷、带鱼、鲾和康氏小公鱼等种类.仔稚鱼以夏季丰度最高,并以鰕虎鱼丰度（71.8%）最高.在分布上,鱼卵的丰度以三都岛东北部和东吾洋海域最高,仔稚鱼以三都岛东部最为密集.这表明本海区的鱼类的主要产卵季节是春季和夏季.其数量、分布与水温及桡足类的分布关系密切.
Based on the data acquired in seasonal investigation in Sansha Bay,the species composition , abundance and important species of fish eggs, larva and juveniles in of February , May, August and November of 1990 was studied and discussed. The resuhs show that totally 26 species of fish eggs,larva and juveniles belonging to 17 family, 22 genus, were recorded in Sansha bay. Fish eggs was the most catch in spring and summer, The main species of the eggs are Pagrosomus major, Trichiurius haumela,Leiognathus sp, , Stoliphorus commersonii, Fish larvae and juveniles was the most catch in summer. Gobiidae is the most abundance. The distribution area of the high abundance region for fish eggs in spring and summer appeared in the east northern part of Sandu Island and Dongwu Yang, and fish larva and juveniles appeared in the eastern and the eastnorthern part of Sandu Island in spring and summer. It shows that the main spawning season is in spring and summer. Close relation was found between the abundant distribution of egg ,fish larva and juveniles and water temperature and Copepods distribution.
