While the American lobster supports Maine's most valuable commercial fishery, the lack of industry support for current stock assessments creates friction between scientists, industry, and managers. To provide a more realistic approach to assessing the lobster fishery, this study will develop a Bayesian stock assessment framework, develop length-based stock assessment models to capture the population dynamics of the lobster, and conduct a simulation study to evaluate the performance of the models and statistical approaches.
