Overfishing in the Gulf of Thailand: policy challenges and bioeconomic analysis
This paper estimates maximum sustainable yield and maximum economic yield from Schaefer and Fox surplus production bioeconomic models to find evidence of biological and economic overfishing, and their consequences in Gulf of Thailand demersal fisheries. The paper examines alternative policy instruments to reduce overfishing. The discussion emphasizes strengthening fishery management for implementing limited access, and a combination of co-management, and decentralization of fisheries management. The use of license fees that serves as a double dividend tax to reduce fishing effort and fund monitoring and enforcement has been proposed as one of the possible economic instruments.

Aquatic resources: collective management patterns and governance for the world's fish wealth
This chapter discusses the social research programme developed and carried out at the WorldFish Centre since 1996, which focuses on community approaches to managing aquatic resources. Two examples are presented, one from Bangladesh and the other from the Philippines, which show how users' participation in resource (fishery) management can promote resource sustainability and reduce poverty. However, the processes to realize the benefits of community participation are not simple and involve substantial investment in innovative institution building. The World Fish Center's social research programme is studying these processes to link theory with field evidence to design effective social interventions.

Outlook for Fish to 2020: A Win-Win-Win for Oceans, Fisheries and the Poor?
The world has observed an unprecedented rise in production, consumption and trade of fish during last three decades. Developing countries as a whole supply nearly 75% of the fish, and represent 50% of the value of global fish trade. At a time when receipts from traditional agricultural exports have been declining, export earnings from fish seem to be paying the food imports bills in many low-income food-deficient countries. While these trends are likely to continue to 2020, questions are being raised about the integrity of world's oceans and fisheries, and the true role of fisheries in eliminating poverty and improving nutritional security of the poor. This paper reviews the changing structure of fish supply, demand and trade, and investigates the impact of fisheries practices on the natural environment, the crucial role of technology, and the role of policy at both national and international levels. The impact of changes can be most profound on the natural environment, and least beneficial to the poorest people in our world community due to the exclusion of the poor from property rights, technologies and markets; the rising price of lowvalue food fish to the poor, and the alarming rate of degradation of fisheries and the environment in developing countries. The complexities of food safety, and public health concerns in the importing countries, can dramatically affect market access by poor citizens in developing countries. Poverty reduction, inclusive development and environmental protection must become more central themes in the dialogue between advocates for the poor and for the environment, representatives of the fish industry, and political leaders and international policy- makers.

Fish as food
\"This paper reports results of incorporating fish into IMPACT, a global model of food supply and demand that estimates market-clearing prices to 2020 for 32 commodities in 36 regions. It summarizes results for production, consumption, net exports and real price changes for 10 economic categories of fisheries items, disaggregated into 15 geographic regions of the world. Under the medium-variant scenario for the uncertain capture fisheries sectors, global production of food fish is projected to rise by 1.5% annually through 2020, with two-thirds of this from aquaculture, whose share in total food fish production rises to 41%. Global per capita fish consumption is projected to be 17.1 kg in 2020, with sensitivity analysis indicating a margin of 2 kg/capita either way based on extreme scenarios for capture and aquaculture. Most growth will occur in developing countries, which will account for 79% of food fish production in 2020. China's share of world production will continue to expand, while that of Japan, the EU, and former USSR will continue to contract. Real fish prices will rise 4 to 16% by 2020, while meat prices will fall 3%. Fishmeal and oil prices will rise 18%; use of these commodities will increasingly be concentrated in carnivorous aquaculture. Growing domestic demand will dampen fish exports from developing countries. Sensitivity analysis incorporating a very pessimistic view of capture fisheries leads to escalating food fish prices (+69% for high-value finfish) and soaring fishmeal prices (+134%), whereas an optimistic view of increased investment in aquaculture lowers real prices of low value food fish (-12%), and raises fishmeal prices (+42%).\" Authors' Abstract
