根据2003～2004年福建海区春季和夏季2个季度月浮游动物调查资料,分析和研究该调查海区浮游动物种类组成和数量分布特点。结果表明:浮游动物经鉴定共有226种,其中桡足类114种,占总种数的50.4%,以广盐高盐亚热带和热带种为主。浮游动物总生物量分布夏季比春季高,春季平均值为90.3mg·m-3,夏季为150.8mg·m-3,春季总生物量呈现由北向南递减,以闽东渔场最高,闽中渔期次之,闽南台湾浅滩渔场最低,密集区不明显,夏季则相反,随着暖流势力的增强,闽中、闽南台湾浅滩总生物量明显增加,以闽南台湾浅滩最高,且密集区明显;在调查海区总生物量起主导作用的优势种为普通波水蚤、锥形宽水蚤、微陀隆哲水蚤、亚强真哲水蚤,其密集区基本上是各种作业的主要渔场,与历史资料和邻近海域相比较,一直保持优势种地位有普通波水蚤、亚强真哲水蚤等,生物密集区基本相同。
According to the survey data of lunar zooplankton in spring and summer from 2003 to 2004 in Fujian sea area, the species composition and quantity distribution characteristics of zooplankton in the survey area were analyzed and studied. The results showed that there were 226 species of zooplanktons identified, of which 114 species were copepods, accounting for 50.4% of the total species, with the most salt and salt subtropical and tropical species. The total biomass of zooplankton in summer was higher than that in spring, the average value in spring was 90.3 mg · m-3 and in summer was 150.8 mg · m-3. The total biomass in spring decreased from north to south, and the highest in Mindong, In the second stage, the Taiwanese shallow shoals had the lowest fishery area in Taiwan and the less densely populated areas. In summer, on the contrary, with the increase of warm flow forces, the total biomass of Minjiang River and Minnan Taiwan shoal increased obviously, The dominant species that dominates the survey of total biomass in the sea area are common water flea, Daphnia magna, Phragmites australis and Acremonium, and its dense area is basically the main fishing ground for all kinds of operations. Compared with the historical data and the adjacent sea areas, the dominant species are the common water fleas, the sub-true philosophical daphnia, etc., and the bio-intensive areas are basically the same.
