Around all survey areas there were totally 8 dominant species in 4 seasons,which were Trichiurus japonicus,Pseudosciaena polyactis,Setipinna taty,Acropoma japonicum,Apogon lineatus,Engraulis japonicus,Champsodon capensis,Psenopsis anomala.

生物多样性指数中丰富度指数和Shannon-Wiener多样度指数变化趋势一致，在春、夏两季3个区域相差不大，而在秋、冬两季黄海南部与东海北部和中部有明显分异；种类均匀度指数在四季节3个区域之间相差不大。

There were lesser and fewer in commercial species and its numbers in the cover net, and the sum of Nemipterus virgatus , Saurida tumbil , Upeneus bensasi , Trachinocephalus myops comprised 95.4% in number and 86.0% in weight of sample catch in the cover net,respectively. The high percentage of juvenile commercial species that were undersized in the codend showed 30.3 mm square mesh codend had more serious damage to most juvenile commercial species, approaching or exceeding 50% in percentage of juvenile species which body length is smaller than fishable size- Trichiurus haumela, Priacanthus tayenus , Navodon tessellatus, Argyrosomus argentatus, Nemipterus bathybius and so on, even exceeding 90% in percentage of juvenile Sepia spp, Loligo spp and Parastromateus niger. In particular, 50% selection lengths ( L 0.5) caught Saurida tumbil and Nemipterus virgatus were smaller than their minimum fishable size.

结果表明，这种规格的方目网囊平均尾数逃逸率为29.76%，平均重量逃逸率为8.46%；出现在套网中的经济种类少、数量少，条尾绯鲤、金线鱼、多齿蛇鲻、大头狗母鱼4种鱼的尾数和重量分别占套网抽样渔获的95.4%和86.0%；网囊中带鱼、长尾大眼鲷、黄鳍马面鲀、白姑鱼、深水金线鱼等鱼种的体长小于可捕标准的个体尾数比例均超过或接近50%，枪乌贼、乌贼、乌鲳等幼鱼尾数比例达90%以上，多齿蛇鲻和金线鱼50%选择体长均未达到最低可捕标准，表明该种规格网囊对多数经济种类幼体的损害比较严重。

So consequencetly difference in age structure of Engraulis japonicus populations would lead to change its element compositions. Since Engraulis japonicus was one of the most important diet to high trophic fishes such as Scomberomorus niphonius and Trichiurus lepturus, Unbalance of supplying elements of potential diets would directly lead to the facts that some fish species would grow slower and smaller.

因此，鳀鱼种群年龄结构的变化导致了种群元素组成的变化，同时由于鳀鱼是上层鱼类的重要饵料，因此潜在饵料的元素供给失衡，直接导致带鱼等鱼类因鳀鱼资源衰退而生长缓慢，个体瘦小。
