ABSTRACT

A framework
was developed for a dynamic multispecies nonlinear optimization
model of five aggregate Bering Sea groundfish fisheries.
The model couples a state space time series model of multispecies
population dynamics with a nonlinear multi-product specification
of twelve harvesting and processing operation categories.
Data developed from the 1991 inshore-offshore cost survey
were used to estimate the parameters of the production
functions. The model structure facilitates statistical
tests of the significance of observed differences among
the operation categories. The estimated econometric model
was not significantly better than a simple model based
solely on the categorical means in the data.
