  fish
Results showed that the relative growth ratio and survival ratio of the fish fed on medium lipid diets (8%) or high ether extract diets (12%) were significantly lower than those of the fish fed on low ether extract diets (4%) (p >amp;lt; 0.05).
      
There was a positive correlation between the ether extract contents in hepatopancreas of fish and the ether extract contents of diets.
      
The main pathological change in ill fish was fatty liver disease.
      
The pathological severity and serious level of fatty liver disease in the tested fish positively correlated with the contents of the ether extract, but not with those of protein, in test diets.
      
Foamy viruses (FVs) have broad cellular tropism infecting vertebrates from fish to human being, which indicates that Env protein has a high capability for membrane fusion.

The composition of the faunas of economic marine fish and non-verbebrate animals commonly harvested in our off-sea fisheries is omplex.Generally speaking,it mainly consists of the species of tropical,sub-tropical and temperature zones.Among them the predominent ones are originated from Indo-Western Pacific tropical and sub-tropical species.They are widely distributed in the range of the south Sea,the East Sea and the eastern sea area of the Taiwan Island.On the contrary,in the areas near to the northern...

The composition of the faunas of economic marine fish and non-verbebrate animals commonly harvested in our off-sea fisheries is omplex.Generally speaking,it mainly consists of the species of tropical,sub-tropical and temperature zones.Among them the predominent ones are originated from Indo-Western Pacific tropical and sub-tropical species.They are widely distributed in the range of the south Sea,the East Sea and the eastern sea area of the Taiwan Island.On the contrary,in the areas near to the northern part of the Yellow Sea and Po Hai(Po Sea),especially the central and northern parts of the Yellow Sea,which covers not too wide an area,the predominent fish are originated from the cold water and warm water species of northern pacific temperature zone. Though their harvest occupies a considerable ratio of the catch yield,from a taxonomic view point the temperature species possess only a small propotion.

我国近海渔业生产上习见的经济鱼类和无脊椎动物的区系组成较复杂。总的说来,以热带、亚热带和温带系成分为主,其中占突出重要地位的是来源于印度一西太平洋的热带和亚热带种,它们广泛分布于南海、东海和台湾以东广大海区,而偏在北部的黄、渤海,特别是黄海北、中部这一范围不大的局部海区,则以起源于北太平洋温带区的冷水种和温水种占优势,在整个中国海区的经济种类中,尽管温带种的产量不少,但其种数所占的比例极少。

This article aimsto give the dependance of main satellite information on the delimitation of fish fauna in tables,to explore the time-space relevance of the distri- bution of water-system in Yellow and East China seas and its regular change represented by the information of satellite image to the forming of fish ground with high production,by means of the analysis of years information from Yellow and East China seas by satellite image and the investigation of the difference of fish habitat...

This article aimsto give the dependance of main satellite information on the delimitation of fish fauna in tables,to explore the time-space relevance of the distri- bution of water-system in Yellow and East China seas and its regular change represented by the information of satellite image to the forming of fish ground with high production,by means of the analysis of years information from Yellow and East China seas by satellite image and the investigation of the difference of fish habitat in the seas with fish catch in geographic position and fishing seasons shown by the information extracted from satellite CCT data and image.Some examples indicated the oceanic environment of Yellow and East China seas is of such speoific characteristics that the oceanic information transfered by satellite image is clear in such a case. Obviously it will be of great help to fully utilizing the information of remote sensing in fishery forecasting and new fishing ground oxploitation.

本文旨在通过对黄、东海多年的卫星影象信息分析,参证了海区鱼类生态环境与捕捞渔获量,在地理上、季节上的差异性,应用卫星 CCT 数据与图象提取信息标志,列出了主要卫星信息与鱼类区系划分的相关表;并寻求卫星影象信息所表征的黄、东海水系配置及其变动规律与形成中心渔场在时空上的相关性。若干实例表明,黄、东海所具有的海洋环境特殊性,对此卫星影象所传递的信息清晰性,显然,大大有利于我们今后充分借助遥感信息进行渔情预报、协同海上侦察与开辟新的渔场。

The northern part waters of Zhejiang Province is not only the main spawning and feeding ground for important valued fishe,also an ideal habitat for small fishing fishes.The decrease of main valued fish resource in recent years has resulted in the opportunity for full growth and reproduction of small fishes.So the relative and absolute amount of the latter has obviously increased.This paper,based on the investigation data,submits an analysis of the distributive delimitation,their charact- eristics...

The northern part waters of Zhejiang Province is not only the main spawning and feeding ground for important valued fishe,also an ideal habitat for small fishing fishes.The decrease of main valued fish resource in recent years has resulted in the opportunity for full growth and reproduction of small fishes.So the relative and absolute amount of the latter has obviously increased.This paper,based on the investigation data,submits an analysis of the distributive delimitation,their charact- eristics and regular fluctuation of the small valued fishes such as Harpodon nehereus, Myctophum pterotum,Collichthys lucidus etc.Finally an evaluation of present resource amount and a suggestion for their exploitation are put forward.

浙江北部沿岸海域不仅是主要经济鱼类的产卵场及其幼鱼的索饵、育肥场,而且是众多的小型经济鱼类的栖息、生长、聚集的优越场所。近年来,随着传统的主要经济鱼类资源的衰减,导致小型经济鱼类获得充分繁殖与生长的机会,其相对与绝对数量明显增加。本文根据调查所得资料,对可供利用的小型经济鱼类,如龙头鱼,风鲚、棘头梅童鱼、鳀鱼、黄鲫等的分布范围、特点及变动等情况进行分析,该项鱼类的资源现存量进行了估算。最后提出一些开发利用的意见。
