Given the heterogeneous nature of the fishing fleet and the complex behavior of vessels, the traditional marginalist supply models are not well suited for modelling vessel mobility. A discrete choice model is utilized in this analysis to predict the probability that a vessel will enter, exit, or remain in the Gulf of Mexico shrimp fishery based on a myopic profit maximization criteria. The multinomial legit model indicates that fisherman behavior in the Gulf of Mexico shrimp fishery is not influenced by stock variability. The crowding externality as represented by the size of the fishing fleet exhibited a strong negative impact on the probability of entry by fishing vessels independent of changes in abundance, exvessel prices, or harvesting costs. Lastly, the Gulf of Mexico shrimp fishery was not an autonomous system of fishing vessels as was initially believed.
