Marine fisheries are in a state of crisis One of the few successfully managed fisheries is the Maine lobster industry where catches are at an all time high. An important factor in this success is the effectiveness of regulations which were developed during three periods over the course of the past 125 years. In all cases, the regulations are the result of heavy lobbying activity by various factions in the industry. Both strong commercial rivalry and genuine concern for the well-being of the lobster resource played a role in generating these regulations However history did not repeat itself In each period the players, circumstances, and goals were very different The result, however is a set of effective regulations which are largely self-enforcing.
