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 hematic properties and biochemical indices of Epinephelus coioides were studied

与历史间期资料相比，经济性鱼在种类上和数量上都有所减少，低价值鱼类比例的增加成为调查区仔稚鱼资源结构的变动趋势，表明长江河口水域经济种类仔稚鱼资源已受到严重的威胁。

This parasite moves from fish to fish with a flagellated spore, and it can live off of the fish for at least 24 hours, and probably longer, up to several days.

这寄生虫的举动从鱼的鱼与 flagellated 孢子，它可以活过的鱼在至少24小时，并可能更长的时间，直至数天。

With the increase of feeding frequency, the specific growth rate in wet weight for juvenile gibel carp increased significantly, and the apparent digestibility of protein and energy increased significantly while the apparent digestibility of dry matter showed no obvious variation.

随着投喂频率增加，异育银鲫幼鱼的湿重特定生长率显著增加，饲料蛋白质和能量的表观消化率显著性增加，而干物质的表观消化率没有显著性变化；投喂频率对异育银鲫幼鱼的生长分化、存活率没有显著性影响；异育银鲫幼鱼的最佳投喂频率为24m/d

隆头鱼一种主要生长于热带的隆头鱼科海鱼，颜色经常是亮丽的，有刺状的鳍、厚嘴唇和有力的下腭，常用作珍贵食用鱼

In the acute toxicity experiments, the 96h-LC50 were 1.0×105 cells·mL-1 for the intact algal solution and 8.0×104 cells·mL-1 for the lysate. In a 7 day subacute experiment on the larvae, higher concentrations of algal solution inhibited S. macrocephalus larvae. The toxicity of the algal solution was higher than that of the lysate at the same concentration.

在仔鱼96h的急性毒性实验中，微小亚历山大藻对仔鱼的96h理论半致死浓度分别为1.0×105 cell·mL-1、8.0×104 cell·mL-1，而在7d的亚急性实验中，高浓度藻细胞液对仔鱼的生长发育有一定的抑制作用，且相同浓度下，藻细胞液产生的毒性较藻细胞破碎液大。

In the acute toxicity experiments, the algal solution and breakup solution of the concentration of 96h-LC50 were 1.0×105cells/mL and 8.0×104cells/mL, respectively. In the subacute 7 days experiment of the larvae, higher of the algal solution has the inhibition effect on sparus macrocephalus larvae. The toxicity of algal solution was higher than that of breakup solution at the same concentration.

在仔鱼96h的急性毒性实验中，微小亚历山大藻对仔鱼的96h理论半致死密度分别为1.0105 cell·mL-1、8.0104 cell·mL-1，而在7d的亚急性实验中，高浓度藻细胞液对仔鱼的生长发育有一定的抑制作用，且相同浓度下，藻细胞液产生的毒性较藻细胞破碎液大。
