This work reports on the implications of an extreme climatic event among owners of fishing grounds in the spiny lobster (Panulirus argus) fishery of Punta Allen, Mexico. This MSC certified small-scale fishery is co-managed through Territorial User Rights. Members of the fishing cooperative, have exclusive access to individual fishing grounds within Ascension Bay. The fishery is based on the use of artificial shelters. These bottom devices provide refuges for lobsters, reduce predation mortality, and facilitate harvesting by free diving and the use of hand nets. This allows under -sized individuals and berried females to be returned to their natural environment. The rainiest season in the region within 40 years occurred in 2013 and affected the spatial distribution of lobsters within the fishing grounds. The lobsters moved away from areas exposed to higher freshwater inflow to areas less exposed to this inflow. In order to determine and contrast the distributional effects in the fishery with and without this extreme climatic event, cooperative log books were used to calculate revenues and quasi-profits for fishing cooperative members (by Gini Index) in eight consecutive fishing seasons (including the fishing season affected by the extreme rainfall). Additionally, fisher interviews were performed to determine how cooperative members dealt with this climatic challenge. Results indicate that the extreme rainfall event had a spatial effect on the distribution of revenues and quasi-profits throughout the fishing grounds. Nevertheless, cooperative internal agreements successfully dealt with the climate challenge by keeping the quasi-profits for fishing trips positive.
