福建近海五种主要捕捞作业适宜捕捞力量的研究

Optimum fishing effort of five fishing methods off Fujian

本文根据福建省定置、拖、围、刺、钓五种捕捞作业在本省近海的捕捞力量（功率）和渔获量，并以1994年单住功率的渔捞效率为基准进行逐年捕捞力量的标准化，应用Schaefer和Fox两种模式，采用微电脑分别估算它们的fMSY和MSY。结果两种模式估算的fMSY和MSY的平均值是：定置网为8． 90万kW，37．41万t；拖网为55．88万kw，35．51万t；灯光图网为7．12万kw，10．06万t；刺网为15．19万kW，9．50万t；钓业为3．77万kW，1．58万t。1994年实际的捕捞力量和渔获量，除灯光围网不及估算的MSY和fMSY。值外，其余四种作业不同程度地超过了估算的MSY和fMSY。文中还讨论了捕捞力量的调整等问题。

Based in the data fishing staistics of Fujian Province from 1971 to 1994,the fishing efficiency of per tonnage or kilowatt of fishing boats power in 1994 are selected for standardizing fishing,effort.The Schaefer and Fox Petterns are used to estimate the MSY and the fMST of the fishery of set net,trawling,light seining,gill net and hook,respectively,The value of the two patterns are as follows the MSY and the FMSY of the set net is 374 kt and 89 thousand kW respectively,the trawling is 355 kt and 588thousand kW the light seiming is 100 kt and 71 thousand kW the gill net is 95 kt and 151.9 thousand kW and the hook is 15.8kt and 37.7 thousand kW .Adjustment of the fishing effort are discussed
