摘要
以海洋生态系营养动力学为基础 ,采用Steele模式估算闽南 台湾浅滩渔场中上层鱼类资源年生产量为 86 4.6 3kt,进而以鲐鱼参鱼类群聚资源在中上层鱼类资源的比例 ,估算鲐鱼参鱼类群聚资源的年生产量为 5 1 9.5 6kt。Gulland和MSY简单模式估算鲐鱼参鱼类群聚资源的最大持续产量分别为 2 5 0 .5 7kt和 2 5 9.78kt。Schae fer和Fox剩余产量模式估算鲐鱼参鱼类群聚资源的最大持续产量分别 2 36 .0kt和2 34.1kt,最大持续捕捞力量分别为 1 1 40 4.1和 1 2 6 6 6 .6MW·d ,折算为福建灯光围网渔船分别为 42 4和 471组 ,并从开发现状和种群生态学及捕捞死亡等参数分析鲐鱼参鱼类群聚资源的开发前景。
In this paper, based on the trophic dynamic in marine ecological system, the biomass of pelagic fish resources is estimated to be 864.63kt using Steele(1974) model in Minnan Taiwan Shoal Fishing Ground. According to the share of the chub mackerel and round scad in biomass of pelagic fish,the biomass of chub mackerel and round scad is estimated to be 519.56kt. The MSY are estimated to be 250.57kt and 259.78kt using the Gulland and simple models, and to be 236.0kt and 234.1kt using the Schaefer and Fox models respectively. The f MSY are estimated to be 11 404.1 MW·d and 12 666.6MW·d.The amount of f MSY are equal to 424 groups or 471 groups light seining boat of Fujian province. The ecology of population and the parameters of fishing mortality, the present situation offishery and the exploitive potentiality are disussed.
