摘要: 本文根据2008年5月(春季)和8月(夏季)在东山湾(23o43′41"~23o52′05"N,117o28′27"~117o34′05"E)开展鱼卵、仔稚鱼的调查资料,分析和讨论东山湾鱼卵和仔稚鱼的种类组成、丰度的时空分布状况。结果表明:本调查海区已分析鉴定的鱼卵仔稚鱼24种,其中16种鉴定到种,4种鉴定到属,4种鉴定到科,还有2种未能鉴定;在春、夏两季期间东山湾鱼类生殖活动频繁,海区出现大量的鱼卵、仔稚鱼;鱼卵、仔稚鱼数量以脂眼鲱(Etrumeus teres)、金色小沙丁鱼(Sardinella aurita)、青鳞小沙丁鱼(Sardinella zunasi)、少鳞鱚(Sillago japonica)和白姑鱼(Argyrosomus argentatus)等经济鱼类为多;春季鱼卵密集区主要分布于东山湾中西部近岸水域,夏季鱼卵密集区分布在东山湾口塔屿附近水域;与福建其他海湾相比较,东山湾是洄游性经济鱼类重要的卵场所之一。

Abstract: Abstract: Based on the surveys data of fish eggs, larvae and juveniles in Dongshan Bay of Fujian in Spring(May, 2008) and Summer(August, 2008) and historical related data, the composition and abundance of temporal-spatial distribution of fish eggs, larvae and juveniles in Dongshan Bay were studied. The results showed that: there were 24 species of fish eggs, larvae and juveniles in survey stations, of which 16 were identified to species, 4 to genus, 4 to family and 2 unidentified. The fish is active in reproductive during spring and summer, while there are plenty eggs and larvae in the bay. The number of fish eggs, larvae and juveniles were mainly consist of migratory economic species, such as Etrumeus teres, Sardinella aurita, Sardinella zunasi, Sillago japonica and Argyrosomus argentatus. Intensive areas of fish eggs in spring is in coastal water of west of Dashuang Island and coastal water of nearest of Ciziwei Nuclear Power Plant, while in Tayu near the bay estuary in summer. In compare with other gulfs in Fujian, Dongshan Bay is an important spawning ground for migratory economic fish on account of its long spawning period. So, its economic value is more important than Quanzhou Bay and Sansha Bay.
