| 根据2011年4月、5月与6月对浙江南部沿岸产卵场进行的共3个航次的调查资料, 对该海域的鱼卵、仔稚鱼的种类组成和数量分布进行了分析, 结果表明, 共发现鱼卵、仔稚鱼72个种类, 分别隶属11目38科48属。其中鱼卵29种, 分别隶属6目18科24属; 仔稚鱼55种, 分别隶属10目29科40属。4—6月仔稚鱼数量呈逐月递减的趋势, 而鱼卵数量6月最多, 5月最少。鱼卵优势种4月以斑 、棱 、小黄鱼与蓝点马鲛为主, 5月以斑 、鳀、龙头鱼、银鲳、蓝点马鲛与石首鱼科为主, 6月以鳀、龙头鱼、多鳞 与鲱科鱼类为主; 仔稚鱼优势种4月以虾虎鱼类、褐菖鲉与平鲉科为主, 5月以鳀、虾虎鱼类、棱 、斑 与长鳍篮子鱼为主, 6月以鳀与虾虎鱼类为主。斑 、鲳鱼、小黄鱼、棱 、蓝点马鲛与褐菖鲉的产卵盛期为4月, 而鳀与龙头鱼的产卵盛期为6月。 |

| Abstract: |
| Based on the data of three surveys in the spawning ground along the south coast of Zhejiang province from April to June 2011, the species composition and spatial distribution of fish eggs, larvae and juveniles were analyzed. The results showed that 72 fish species were identified, belonging to 48 genera of 38 families in 11 orders. Among them, eggs of 29 species were in 24 genera of 18 families in 6 orders, together with larvae and juveniles of 55 specie in 40 genera of 29 families in 10 orders. The quantity of fish larvae and juveniles showed a tendency of decrease by month from April to June, while the largest number of fish eggs was in June, followed by April and then May. As for the dominant species of fish eggs, April mainly saw Clupanodon punctatus, Liza carinatus, Pseudosciaena polyactis, Scombermorus niphonius; May mainly saw C. punctatus, Engraulis japonicus, Harpodon nehereus, Pampus argenteus, S. niphonius, Sciaenidae sp. and June mainly saw E. japonicus, H. nehereus, Sillago maculate and Clupeidae sp.. As for the dominant species of fish larvae and juveniles, April mainly saw Gobiidae sp., Sebastiscus marmoratus and Sebastidae sp.; May mainly saw C. punctatus, E. japonicus, Gobiidae sp., L. carinata, C. punctatus and Siganus canaliculatus; June mainly saw E. japonicus and Gobiidae sp. The main species with peak period of spawning in April include C. punctatus, P. argenteus, P. polyactis, L. carinatus, S. niphonius and S. marmoratus, and those in June include E. japonicas and H. nehereus. |
