Title: THE USE OF OPTIMAL FORAGING THEORY IN THE UNDERSTANDING OF FISHING STRATEGIES - A CASE FROM SEPETIBA BAY (RIO-DE-JANEIRO STATE, BRAZIL)
Author: BEGOSSI, A
Abstract: The community of Gamboa is located on Itacuruca Island, Sepetiba Bay (State of Rio de Janeiro, Brazil) and includes 26 families, mostly of artisanal fishermen who use paddled or motor canoes, and encircling nets for fishing. In this study, predictions from optimal foraging theory (patch model), in particular of patch residence time, are compared to the observed behavior of fishermen on fishing trips. Fishermen's strategies differ depending on their intended prey. They spend more time in patches and use fewer patches for shrimp than for fish. Gamboa's fishermen tend to leave a patch later than predicted by the model. The difficulty in evaluating stock availability, the comparatively few patches available for shrimp, and the competitive aspects of fishing contribute to the explanation of this behavior.
