摘要
根据统计资料，利用剩余产量模型专家系统对东海鲐Ｓｈｅｎ鱼类最大持续产量作了谰估分析。结果表明；东海鲐Ｓｈｅｎ鱼类化整为零分析时的ＭＳＹ在３４．５－４４．２万吨之间，按种类分别评估时，鲐鱼的ＭＳＹ为１６．１万吨、蓝圆Ｓｈｅｎ万吨，按区域分析时，鲐Ｓｈｅｎ鱼类东海北部群的ＭＳＹ为１２．５－１３．２万吨，福建沿海群为２０．１万吨。
Based on the statistical data, the Maximum Sustainable Yield(MSY) for the different stocks of chub mackerel and round scad in the East China Sea were estimated by the surplus production models fitting expert system (CLIMPROD). The result showed that the MSY for stock of combining the two speies for East China Sea was between 345 ~ 442 000 an tones. It was 125 ~ 132 000 tones for the northern area and 201 000 tones for the southerm. when estimated for stock of different species, the MSY was 161 000 tones for chub mackerel and 222 000 tones for round scad.
