Fisheries is a critical sector for food security and economic growth in the Pacific region. Maintaining up-to-date information about the impact of fisheries is critical for Pacific Island countries and territories (PICTs) and their communities to make informed decisions about management of the sector, and for a range of development organisations, institutions and donors to plan and implement effective development assistance in collaboration with PICTs. However, finding accurate and up-to-date data on the value of fisheries, and its numerous components, to the economies of Pacific Island countries and territories is very difficult, and this makes the assessment of development and change very difficult to measure over time. This book contains a fisheries-oriented discussion of macroeconomics, country information on specific topics (fisheries production, contribution to GDP, etc.), a discussion of important topics across all countries (e.g. the regional significance of fisheries access fees and exports of fishery products), some important features of the benefits from fisheries that have emerged from this study, and recommendations on improving the measurement of fisheries benefits and assuring the continuity of those benefits. It provides a new baseline for assessing the value of fisheries to Pacific Island countries and territories (PICTs), both for measuring achievements and for assessing future improvements in sustainable fishery management. It documents changes in the management of the Pacific tuna fishery, food security concerns for coastal fisheries in the face of growing populations, and the effects these have on the economies of PICTs.
