【摘要】 根据2007年8月、11月桁杆拖网、三重刺网和倒须笼壶三种作业类型的海区大面探捕调查,以及2007年10～12月在湄洲湾电厂冷却水过滤池内采集样品的鉴定分析,结果表明:湄洲湾游泳生物种类繁多,共有157种,隶属18目66科117属。其中,鱼类97种、蟹类32种、虾类20种、口足类6种、头足类2种。鱼类区系组成较为复杂,以适温性看,暖水性种类居优势,有71种,占73.20%;暖温性种类较少,有26种,占26.80%,鱼类区系具有明显的热带和亚热带特征。从鱼类生态类型的分布看,底层鱼类种类数占大多数,有55种,占56.70%;其次为近底层鱼类,有25种,占25.77%;中上层鱼类位居第三,有9种,占9.28%;岩礁性鱼类最少,仅有8种,占8.25%。从甲壳类生态类型的分布看,分布于浅海的种类数最多,有26种,占44.83%;其次为分布于潮间带和浅海的种类,有23种,占39.66%;分布于潮间带的种类最少,仅有9种,占15.52%;资源结构以中小型鱼类、蟹类和虾类为主,且幼鱼幼体比例高、个体普遍较小。更多还原

【Abstract】 According to the sample identification of the large region test fishing by beam trawl,trammel net and pot on August and November in 2007 and by collecting in cooling water of filtering pool at the electric power station of Meizhou Bay during October to December in 2007,the results showed that species of nekton are more,a total of 157 species belongs to 18 orders,66 families and 117 genuses,and there are 97 species of fish,32 species of crab,20 species of shrimp,6 species of squilla and 2 species of cephalopod. The faunal of fish is complicated which has obviously character of tropical and subtropical region,the warm water species is dominant with 71 species occupying 73.20%,and the warm-temperate species has 26 species occupying 26.80%.Based on the ecological group of fish,the bottom fishes are most with 55 species occupying 56.70%,the near-bottom fishes are second with 25 species occupying 25.77%,the pelagic fishes and the rocky habitat fishes have 9 species and 8 species occupying 9.28%and 8.25%resrespectively.The species in shallow sea of crustaceans are most with 26 species occupying 44.83%,the second is in inter-tidal region and shallow sea with 23 species occupying 39.66%,and the species in inter-tidal region are few with 9 species occupying 15.52%.The resources structure is compose of the small and medium-sized fishes,crabs and shrimps,the juvenile are most and individual size are generally small.更多还原
