南沙群岛海域岛礁鱼类资源的开发现状和开发潜力

EXPLOITIVE STATUS QUO AND POTENTIAL OF CORAL REEF FISHERY RESOURCES IN NANSHA ISLANDS WATERS

南沙群岛海域蕴藏着丰富的礁栖性鱼类资源,是我国珊瑚礁渔业的主要作业渔场。根据近年来的渔业生产数据对开发现状进行了评价,判断南沙群岛岛礁鱼类资源尚处于轻度开发状态。通过采用初级生产力方法估算,南沙群岛岛礁水域鱼类的年生产量不低于2.1t·km-2,以年生产量的50%估算,潜在渔获量不少于5.5万t。

Nansha Islands waters is the main fishing ground of coral reef fishery industry of China, where there are abundant reef fishery resources. Taking advantage of fishing data of late years, the status quo of exploitation is evaluated, and the reef fishery resources of Nansha Islands waters is considered on a status of light exploitation. Stock assessment by means of primary productivity shows that the yearly capacity of fishes in the reef waters of Nansha Islands is not less than 2.1t·km^(-2). And calculating by 50% of the yearly capacity, the potential catch would be up to 55 thousand tons.
