ABSTRACT

The catch of skipjack, yellowfin, bigeye, albacore and bluefin tuna accounts for about five percent of the world production of marine fish, but it represents a much higher proportion of the total value of the catch. With the exception of skipjack, most stocks of tuna are nearly fully exploited or overexploited. As the number and efficiency of vessels that harvest tuna increases, there is a growing concern on the part of nations and international tuna bodies that it will become increasingly difficult to implement and sustain effective conservation measures for tunas. As a consequence, most of the tuna bodies have initiated steps to evaluate the needs and means of limiting the capacity of the vessels in the fisheries with which they are concerned. Because of severe economic problems associated with excess fishing capacity, the fishing industry has initiated its own programmes to limit the capacity for purse-seine and longline fleets. Reasonably good catch statistics for tuna are available for most fisheries, but corresponding information on the numbers and characteristics of tuna vessels is frequently not. For one of the areas where information is available (the eastern Pacific) results of Data Envelopment Analysis suggest that the fleet of purse-seine vessels in the area could be reduced significantly without a corresponding reduction in the catch. So far, there has been very limited action taken by the fishery bodies to control the fishing capacity. The tuna fishery bodies must work together, and with FAO to resolve the problem of tuna fishing capacity. They also need to address the issues related to common property resources and property-rights based management, the allocation of catches and fleet capacities among participants, the rights of access on the high seas, the authority for regional tuna organizations to deal with some of these matters.
