为探讨南海北部渔业资源的可持续利用情况 ,根据 1997年 12月～ 1999年 6月“北斗”号调查船SimradEK5 0 0回声探测 积分系统在南海北部海域获取的渔业资源调查资料 ,对该海域天竺鲷科、科、灯笼鱼科、鳄齿鱼科以及犀鳕科等 5类 5 8种小型非经济鱼类进行了资源量评估。结果表明 ,这些种类在南海北部海域具有比较丰富的资源储量 ,它们春、夏、秋、冬 4个季节的平均资源量分别为 18.5× 10 4t,2 6.1× 10 4t,2 2 .3× 10 4t,17.6× 10 4t和 4.5× 10 4t ;分析了其资源量的区域分布和季节变化。
In order to explore the sustainable utilization of fishery resources in the northern South China Sea, according to the survey data of the fishery resources acquired by the Simrad EK5 0 0 echo sounding system of the Beidou survey ship in the northern South China Sea from December 1997 to June 1999, Five species of 58 small non-economic fish such as the family Breamidae, Tarsidae, Lifescience, Crocodileidae, and Rhinoceros were evaluated for their resources. The results showed that these species had rich reserves in the northern South China Sea. The average resource of these species in spring, summer, autumn and winter were 18.5 × 10 4 t, 2 6.1 × 10 4 t and 22.3 × 10 4, respectively 4t, 17.6 × 10 4 t and 4.5 × 10 4 t respectively. The regional distribution and seasonal variation of its resources were analyzed.
