【摘要】 本文采用Jones(1981)体长股分析法和剩余产量模型对北纬28°30′—31°30′,东经124°30′以西海域7—10月的秋季上层鱼资源状况进行了评析。本海域上层鱼资源以鲐鱼数量居首位,其次为蓝圆鲹。上层鱼资源约144万担,可提供持续产量70—80万担,最佳捕捞力量为211组左右。更多还原

【Abstract】 The pelagical fish resources to the west of 124@@30’E, 28?0’-31@@30’N in autumn (from July to Oct.) are estimated with Jonse (1981) Length Cohort Analysis and Surplus Yield Model. The amout of Mackerel ranks the first in this area’s pelagical fish resources, and the next is Round Scad. The total pelagical fish resources are estimated to be about 72500 tons. The catchable sustain-able yield is 35000-40000 tons.更多还原
