摘要翻译:
本研究将发展并应用一种方法,藉由船队空间行为的决策分析,来估计渔业资源生物量的生物迁移参数。首先,对离散选择模型进行了估计,并给出了贴片捕获函数。这将允许估计每个斑块的生物量可用性。在第二个回归中,生物量值被用来估计斑块之间的生物迁移模型。该方法在智利鲭鱼渔业中得到了验证。这将有助于估计具有统计意义的迁移参数,确定迁移模式。

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.
