  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.
