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。

By R type analysis, the results show that there are 4 species, Raja kanojei, Coilia mystus, Muraenesox cinereus and Collichthys niveatus, which are correlated closely in spring;and 5 species, Engraulis japonicas, Pseudosciaena polyatis, Lophius litulon, Chelidonichthys kumu and Saurida elongate, in summer; and 5 species, Trichiurus haumela, Pampus nozawae, Erisphex potti, Pneumatophorus japonicas and Pseudosciaena polyatis, in autumn; and 3 species, Trichiurus haumela, Champsodon capensis and Acropoma japonicum, in winter.

根据2000年春（4月）、夏（6月）、秋（9月）、冬（12月）四季东海、黄海底拖网鱼类资源调查资料，使用因子分析的方法分析了该海域鱼类数量分布的季节变化特征。R型分析发现，春季关系最密切的鱼种有4种：斑鳐、凤鲚、海鳗和黑鳃梅童鱼；夏季有5种：鳀、小黄鱼、黄鮟鱇、绿鳍鱼和长蛇鲻；秋季也有5种：带鱼、灰鲳、虻鲉、日本鲭和小黄鱼；冬季有3种：带鱼、鳄齿鱼和发光鲷。

The major bycatch species of sergestid shrimp mid-trawl and planktonic shrimp mid-trawl was Trichiurus lepturus, while the Harpadon microchir and Gerres filamentosus were the main bycatch species for bottom shrimp trawl and shrimp beam trawl, respectively.

四种渔业混获与目标渔获比为1.93~15.08，以桁杆式虾拖网最高，其余三种渔业皆在3.3以下，正樱虾及中型毛虾中层拖网混获最多的种类为白带鱼，底层虾拖网为小鳍镰齿鱼，桁杆式虾拖网为曳丝钻嘴鱼。

Moreover, fatty acid composition also indicated environment change. For example, cold temperatefishes such as Liparis tanakae and Hexagrammos otakii had more polyunsaturated fatty acids than warm species such as Pseudosciaena polyactis, Trichiurus lepturus and Scomberomorus niphonius.

此外，鱼类的脂肪酸组成还反映了生长环境的差异，冷温性鱼类(如细纹狮子鱼和大拢六线鱼)比暖水性鱼类(小黄鱼、带鱼和蓝点马蛟等)含有更高含量的高度不饱和月旨肪酸。

Based on the bottom trawl surveys conducted in the central and southern Yellow Sea in autumn during 2000-2002, the food consumption by 23 fish predators such as Trichiurus lepturus, Pseudosciaena polyactis, Lophius litulon, Liparis tanakae etc. was estimated by Egger's model. The results suggest that the total food consumption by these predators during autumn was over 3.09 million tons.

研究鱼类与饵料生物之间食物定量关系进而为多鱼种资源评估提供依据，2000~2002年秋季（10~11月）在黄海中南部海域进行了定点底拖网调查，应用Egger、模型，计算了带鱼、小黄鱼、黄鮟鱇、细纹狮子鱼等23种鱼类在秋季对饵料生物的摄食量。

On the basis of taxonomy of genus Trichiurus and length-frequency data collected by trawl survey in the northern South China Sea, growth and mortality parameters for three species of Trichiurus were estimated. For T. haumela, T.

根据我国近海带鱼分种研究结果，利用南海北部底拖网调查收集的带鱼属3鱼种的生物学资料，运用长度频率法估算了3鱼种的生长和死亡参数。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
