Abstract

Fisheries biologists use statistical models to transform disparate data, such as catch, research surveys estimates, and the catch rates of fishermen into estimates of abundance, management regulations, and risk analysis. The result is an integrated assessment of a fish stock – a model of population dynamics that can be used to evaluate management decision. The core statistical problem in fisheries is the estimation of parameters of such a model. Such a statistical model combines data from many sources, using a variety of likelihoods, each representing a different piece of the data.
