The Western and Central Pacific Ocean (WCPO) is home to the largest tuna fishery stock in the world. However, Pacific Island members of the Western and Central Pacific Tuna Commission (WCPTC) argue that their share of the economic rent from the tuna catches taken out of the Pacific region is very small, being on average only about 6% of the total net benefit, when compared to the share earned by Distant Water Fishing Nations (DWFNs). Kiribati is one of the Pacific Island Countries (PICs), which relies heavily on its fishery for its economic development and sustainability. Kiribati earns 40% - 50 % of its government revenue from fisheries access fees paid by DWFNs for tuna caught in the the Kiribati EEZ. The Government of Kiribati (GoK) believes that Kiribati could get greater benefit if they develop their own domestic tuna fishery.

This study uses Cost-Benefit Analysis (CBA) and SWOT Analysis to investigate whether domestication of the tuna fishery is the right move for Kiribati or not. The CBA reported in this thesis adapted a model developed by Campbell (2004) to investigate and evaluate fisheries policy in Papua New Guinea (PNG). However the model in this thesis is reflective of the situation and case of Kiribati. In analyzing the different options identified in this study, the CBA indicated negative (-) NPV(s) for the medium-sized vessel option and positive (+) NPV(s) for the large-sized vessel option. The SWOT analysis however, complemented the CBA by further investigating the tuna domestication options in the economic, social and business and business environment of Kiribati. The SWOT analysis indicated that the existing situation and business conditions in Kiribati appears to favor the small to medium sized vessel options which are less risky than the large purse seine vessel option.
