中国海洋鱼类种类多样性的研究

中国海洋迄今已记录有３０４８种鱼类，分属２８８个科，约占全球海洋鱼类总数的２３％，是世界鱼类种类最丰富的国家之一。种类多样性程度由南向北逐渐递减，南海高达２０５０种，但单种资源量小，黄渤海只有３２７种，但一些单种资源量较多，中国海洋针种以暖水种居多样性的高达８７．８％，也有大量暖温种和少数冷温种，但无真正冰水各，中国海缺乏世界级的高产渔获种类。

On Varieties of Marine Fishes in Chinese Sea

There are 3048 species of fishes belonging separately to 288 families recorded in the scientific literature till now in the Chinese Sea. These fishes accounts for 23% of the total ma- rine fishes in the world, thus China is one of countries which have most species of fishes in the world. The varieties of fishes are gradually decreasing from south to north. In the Southern Sea the varieties of fishes are more than 2050 species, but the resource amount of the mono-species is small. In the Yellow Sea and Bohai Sea there are only 327 species of fishes, but the resource amount of mono-species is much bigger. In Chinese Sea the warm water species of fishes are more, about 87. 8%, but there is a few of cold water species as well, as for a real cold water species there is none. The Chinese Sea is short of species of fishes which high yield of catch can meet the world level.
