英文摘要:
In this study, a method will be developed and applied for estimating biological migration parameters of the biomass of a fishery resource by means of a decision analysis of the spatial behavior of the fleet. First, a model of discrete selection is estimated, together with patch capture function. This will allow estimating the biomass availability on each patch. In the second regression, values of biomass are used in order to estimate a model of biological migration between patches. This method is proven in the Chilean jack mackerel fishery. This will allow estimating statistically significant migration parameters, identifying migration patterns.

中文摘要:
在本研究中,将开发并应用一种方法,通过对船队空间行为的决策分析,估算渔业资源生物量的生物迁移参数。首先,估计离散选择模型和斑块捕捉函数。这将允许估计每个斑块上的生物量可用性。在第二次回归中,使用生物量值来估计斑块间生物迁移的模型。这种方法已在智利竹荚鱼渔业中得到验证。这将允许估计统计上重要的迁移参数,确定迁移模式。
