通过分析捕鱼船队的空间行为估计生物量迁移参数
Estimating biomass migration parameters by analyzing the spatial behavior of the fishing fleet
摘要：
在这项研究中，一种方法将开发和应用于估计生物量的渔业资源的生物迁移参数的船队的空间行为的决策分析。首先，估计了离散选择模型和斑块捕获函数。这将允许估计每个斑块的生物量可用性。在第二次回归中，生物量的值被用来估计斑块之间的生物迁移模型。这种方法在智利的竹荚鱼渔业中得到证明。这将有助于估计具有统计意义的移徙参数，确定移徙模式。
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.
