These Proceedings include the report and papers presented at the Methodological Workshop on the Management of Tuna Fishing Capacity: Stock Status, Data Envelopment Analysis, Industry Surveys and Management Options. The Workshop was hosted by the Inter-American Tropical Tuna Commission (IATTC) in La Jolla, California, United States of America, from 8 to12 May 2006 as an activity of FAO’s Japan-funded Project on the “Management of tuna fishing capacity: conservation and socio-economics”. The Workshop was organized by the Project in collaboration with and with financial and in-kind support of: (i) most tuna agencies and programmes; (ii) other international and national fisheries institutions involved in tuna fishing, fisheries research and management (including those of tuna fishing industry); and (iii) some universities.
The objectives of the Workshop were:
1) to develop a method for the estimation of tuna fishing capacity from stock assessment-related information;
2) to determine the feasibility of: (i) routinely collecting input data for the so-called data envelopment analysis (DEA); and (ii) performing industry surveys of tuna fishing capacity utilization;
3) to relate DEA estimates of fishing capacity utilization to traditional estimates of fishing capacity;
4) to review the factors affecting fishing capacity (like the number of vessels and their physical characteristics) that could be regulated by fisheries authorities;
5) to review the existing measures for managing tuna fishing capacity and possibly, to identify additional options for such measures in the context of the outcome of addressing the above-mentioned objectives;
6) to prepare a satement of participants of the Workshop; and
7) to formulate recommendations of the Workshop to the FAO Project on the Management of Tuna Fishing Capacity, FAO and the other institutions participating in the Workshop.
The papers presented in these Proceedings include those associated with objectives 1 to 5. The report documents presentations made at and the discussions carried out during the Workshop, their conclusions and the recommendations. The Statement prepared by the Workshop (see Objective 6) is enclosed in the report. That Statement was presented at the Meeting of Tuna Regional Fisheries Management Organizations, which was held in Kobe, Japan from 22 to 26 January 2007.
