Status of Fishery Resources along the Coastal Waters of Xiangshan Port

2010年4月对象山港附近海域渔业资源现状进行了调查研究。4个站位采集到鱼卵,分别为斑鰶、白姑鱼、带鱼,平均密度为4.58个/m2。10个站位采集到仔稚鱼,分别为脂眼鲱、青麟鱼、斑鰶、油魣、鮻鱼、少鳞鱚、白姑鱼、日本金线鱼、蝦虎鱼科,平均密度为30.83尾/m2;在港顶部区域的拖网几乎没有渔获物,港中部和港口外岛礁附近海域渔获物重量组成最高的分别为鱼类和虾类,各占81.11%和46.77%,尾数组成均是虾类最高,分别占75.43%和92.77%。港中部和港口外岛礁附近海域渔获物相对重量密度分别为1.04 t/km2和127.2 t/km2、相对尾数密度分别为18.5万尾/km2和3 487万尾/km2。

Based on the survey on fishery resources along Xiangshan Port in April 2010. The results showed that fish egg which were Clupanodon punctatus, A rgyrosomus argentatus and Trichiurus haumela was found in four sampling stations, and the average density was 4.58 ind/m2. larvae which were Etrumeus, Haren- gulu sp., Liza, Sillago japonicas, Clupanodon punctatus, Sphyraena pinguis, Sillago japonicas, A rgyrosomus ar- gentatus, Scatophagus japonicus and Gobiidae were found at ten sampling stations, and the average density was 30.83 ind/m2. There was scarcely any fishing gains at the top of ttle port.

The catch relative weight density were 1.04 t/kin2 and 127.2 t/km2, and the relative number densities were 185 000/kin2 and 3 4 870 000/kin2 tail in the central and port area near the island.
