摘要
利用长袋网(fykenet)采集了长江口新生盐沼湿地潮沟内的游泳动物,分析了该类盐沼湿地的鱼类栖息地利用。结果表明,3次调查共记录到游泳动物20种,其中鱼类15种,虾蟹类5种。生态类群主要以淡水性种类(10种)和河口性种类(6种)为主,洄游性种类(3种)和海洋性种类(1种)较少。从数量组成来看,游泳动物群落主要由安氏白虾(35.4%)、棕刺虾虎鱼(17.7%)、贝氏餐(17.7%)、长蛇鮈(9.2%)和日本沼虾(4.6%)等少数几个物种占优势。这些游泳动物大多为稚幼个体,表明长江口新生盐沼湿地是许多鱼类和甲壳动物的重要育幼场所。
The nektons in an intertidal creek of a newly formed salt marsh at Yangtze River estuary were sampled by Fyke net to assess its habitat utilization of the salt marsh. A total of 20 nekton species were recorded in three investigations, including 15 fishes and 5 crustaceans. Among the nektons, freshwater species （10 species） were the most abundant ecological groups, followed by estuarine （6 species）, migratory （3 species）, and coastal species （ 1 species）. In term of numeric abundance, the nektons were highly dominated by Exopalaemon annandalei （35.4%）, Acanthogobius luridus （ 17.7% ） , Herniculter leucisculus （ 17.7% ） , Saurogobio dumerili （9.2%） , and Marobrachium nipponensis （4.6%）. Most of the nektons sampled in this study were juveniles, suggesting that the newly formed salt marsh was the important nursery habitat for many fishes and crustaceans.
