【摘要】 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。更多还原

【Abstract】 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.更多还原
