Aquaculture is still the fastest-growing food-producing sector and plays an important role in enhancing global food security and alleviating poverty. Tens of millions of people are engaged in aquaculture production, the majority of whom are small-scale farmers who have limited resources and are faced with difficulties due to increasing globalization and the resultant trade liberalization of aquaculture products. Despite these challenges, small-scale farmers remain innovative and continue to contribute to global aquaculture production.
India is endowed with a continental shelf of 0.5 million km2 and an exclusive economic zone (EEZ) of about 2 million km2. Almost half (39%) of the Indian population utilizes the marine fisheries resources. India ranked sixth worldwide in total fish production (4.95 million t) and second in inland fish production (2.24 million t) during 1995 - 96. Fish production expanded from 0.75 million t in 1950 - 51 to 4.95 million t in 1995 - 96, giving a significant increase at a cumulative growth rate of 4.2% per annum.
A brief account is given of the results of a grow-out trial conducted regarding the freshwater prawn (Macrobrachium rosenbergii ) in a farm pond in Ghana with water at temperatures of 30-33 C. Results showed that 70% of the prawns achieved lengths of over 13 cm and wet weight of > 35 g, figures which compare favourably with growth rates achieved in other parts of the world. Although M. rosenbergii culture is viable in Ghana, problems exist which prevent further development, the major one being lack of foreign exchange to purchase juveniles.
Small fish are a common food and an integral part of the everyday carbohydraterich diets of many population groups in poor countries. These populations also suffer from undernutrition, including micronutrient deficiencies – the hidden hunger. Small fish species, as well as the little oil, vegetables and spices with which they are cooked enhance diet diversity. Small fish are a rich source of animal protein, essential fatty acids, vitamins and minerals.
The rural populations of southern Bangladesh are some of the most vulnerable communities in the world to the future impacts of climate change. They are particularly at risk from floods, waterlogged soils, and increasing salinity of both land and water. The objective of this project was to analyze the vulnerability of people in four villages that are experiencing different levels of soil salinity.
This chapter examines pangasius catfish aquaculture in Vietnam in the context of changing social relations of production, European consumer trends and regulation. In particular we are interested in how the rise of 'sociotechnical' environmental regulatory networks in the form of quality standards and third-party certififcation have altered power relations between consumers and producers across global space.
Egyptian aquaculture is booming, yet greater fish quality and effective industry support are still needed. A value chain approach is helping research and development partners overcome barriers to sustainable growth.
As part of the Philippines' plan to accelerate the country's rate of aquaculture development, a study team was sent to neighboring Southeast Asian countries to observe advances for improving and developing aquaculture in the Philippines. The 3-man team, of which the author was a member, toured Malaysia, Thailand, Japan, and Taiwan. This article is a brief account of observations from the trip and interviews with authorities from selected fisheries agencies, with emphasis on freshwater aquaculture.
An examination is made of the applications of microcomputers to aquaculture research, considering in particular data storage and processing and also statistical analysis programmes. Reference is made to development projects with the aim of making use of modern, applied research methods to develop aquaculture technologies applicable for developing countries.
People who are food and nutrition insecure largely reside in Asia and Sub-Saharan Africa and for many, fish represents a rich source of protein, micronutrients and essential fatty acids. The contribution of fish to household food and nutrition security depends upon availability, access and cultural and personal preferences. Access is largely determined by location, seasonality and price but at the individual level it also depends upon a person's physiological and health status and how fish is prepared, cooked and shared among household members.
