Keynote: Aquaculture and Sustainable Nutrition Security in a Warming Planet

Fisheries and aquaculture contribute significantly to food and nutrition security. About 20 percent per capita intake of animal protein for more than 2.8 billion people is from fish and for over 400 million people fish meets 50% of the requirement for animal protein and minerals. Malnutrition is still the number one killer compared to other diseases. Climate change is likely to increase the frequency and intensity of climate processes.

Providing high quality feeds for aquaculture and getting out of the fish meal trap: opportunities and challenges

If the aquaculture sector is to maintain its current average growth rate of 8 to 10 percent per year to 2025, the supply of nutrient and feed inputs will have to grow at a similar rate. Feed-fed aquaculture production is largely dependent upon capture fisheries for dietary protein and lipid. Sustainability of the aquaculture sector is likely to be linked with the supply of animal and plant proteins, oils and carbohydrate sources for aquafeeds.

The potential of aquaculture to improve human nutrition and health

Fish makes a vital contribution to the survival and health of a significant portion of the world’s population. In some of Asia’s poorest countries, people derive as much as 75 percent of their daily protein from fish. Aquaculture can assist communities in developing countries to address the potential of fish as a ready provider of essential nutrients, a tradable commodity and as such, a contributor to development and social stability.

Enhancing the contribution of aquaculture to poverty alleviation, food security and rural development

We are passing through an era of increasing population, food shortages and unsustainable farming practices. We cannot think of food security unless issues connected with poverty and livelihoods are addressed. Since 75 percent of global aquaculture production comes from small-scale farms in developing countries we have to address a number of issues to ensure that the livelihoods and food security of all those involved in the sector are not threatened.

Expert Workshop on Inland Fisheries Resource Enhancement and Conservation in Asia

Over the past few decades inland fisheries resources have come under increasing pressure from water engineering projects, pollution and overfishing. FAO and NACA convened an expert workshop to review inland fisheries resource enhancement and conservation practices in Pattaya, Thailand, 8-11 February. Experts from 10 Asian countries attended the meeting to share experiences and lessons learned. Regional collaborative efforts are required to facilitate assessment of current inland fisheries resource enhancement and conservation practices.

Economics of aquaculture feeding practices in selected Asian countries

This technical paper provides an analysis of the economic implications of, and the reasons for, adopting various feeding practices for different fish species and aquaculture systems in Asia. The systems studied include extensive/traditional, semi-intensive and intensive farms for a number of different species including sutchi and pangasiid catfishes (Bangladesh and Viet Nam), hybrid catfish (Thailand), carp polyculture (India and China), prawn and milkfish polyculture (the Philippines).
