摘要
本文根据2007年3月至2008年2月期间在泉州地区3个海湾的调查资料,对其浮性鱼卵和仔稚鱼的种类组成与数量分布特点进行初步研究和探讨.结果表明,本调查海域共出现鱼卵和仔稚鱼51种(含未定种),隶属于21科,主要是近岸底层鱼类、近海中上层鱼类和港湾河口型鱼类三个生态类型.各站鱼卵总平均丰度是81.2粒/网,仔稚鱼总平均丰度31.0个/网.数量平面分布呈现优势种明显,占总量比例大,不同季节不同海湾差别较大,规律性不强等特点.整体数量上与往年比有下降趋势.
Based on the survey data in Quanzhou Bay, Weitou Bay and Maizhou Bay in March 2007, August 2007 and February 2008, we discussed the distribution of species and abundance of pelagic fish eggs, larvae and juveniles. The results showed that a total of 51 species belonging to 21 Family were recorded. They can be classify 3 eco-type：coastal benthic fishes, epipelagic and mesopelagie fishes, estuarine fishes. The mean abundance of fish eggs is 81.2 ind/net, and that of larvae and juvenile is 31.0 ind/net. Abundance distribution shows that dominant species are obviously different among bays with no seasonal trend. The abundance of fish eggs, larvae and juveniles decreased in bays in recent years.
