A socioeconomic and bioeconomic analysis of coastal fisheries of Bangladesh

Bangladesh has an exclusive economic zone (EEZ) of 164 000 km2 and a continental shelf area of 66 440 km2. Artisanal (small scale) fisheries extend from the coast to 40 m while industrial (commercial scale) fisheries operate beyond 40 m depth. The coastal fisheries of Bangladesh exploit a complex multi-species resource. There are 18 demersal and pelagic species, seven species of larger pelagic and 10 shrimp species that are commercially important among the fishes exploited.

Smallholder farmers in Malawi adopt and improve technologies from collaborative research

Details are given of the various new technologies demonstrated by ICLARM and the Fisheries Department in Malawito smallholder farmers, which include the following: 1) Use of Pennisetum purpureum as an alternative/supplement to maize bran as fish feed; (2) Creation of high quality compost from poor quality plant wastes as fish food or fertilizer; 3) Vegetable-pond integration using pond sediments and water for adjacent vegetable beds; 4) Integration of chicken and fish enterprises; 5) Pond stirring with a bamboo rake for lifting nutrients from the pond bottom into the water column; 6) Use of

Small-scale aquaculture development model for rural Nepal

The majority of rural farmers in Nepal are small holders and their livelihood is based on agriculture. Three projects on small- scale aquaculture, with focus on women’s involvement, were completed in Kathar and Kawasoti Village Development Committees (VDCs) of Chitwan and Nawalparasi districts, respectively during 2000-2007. Based on the experience from these projects, guidelines/ steps for the development of small-scale aquaculture in rural areas were drawn.

Shrimp (Penaeus monodon) farming in the coastal areas of Bangladesh: Challenges and prospects towards sustainable development

This chapter mainly presents the history of shrimp aquaculture in Bangladesh and impacts of shrimp farming on rural livelihoods with particular focus on income and dietary consumption, based on literature reviews and structured field surveys. The chapter also focuses on the complexities of land use patterns and recommends a holistic approach to adopt integrated zoning principles into national policies to sustain shrimp farming in Bangladesh.

Selective breeding in fish and conservation of genetic resources for aquaculture

To satisfy increasing demands for fish as food, progress must occur towards greater aquaculture productivity whilst retaining the wild and farmed genetic resources that underpin global fish production. We review the main selection methods that have been developed for genetic improvement in aquaculture, and discuss their virtues and shortcomings. Examples of the application of mass, cohort, within family, and combined between-family and within-family selection are given.

Review of environmental impact, site selection and carrying capacity estimation for small scale aquaculture in Asia

Asia is the leading aquaculture region in the world, contributing to 85% of total world aquaculture production. Of the top 10 aquaculture producing countries 9 are Asian with China accounting for more than 65% of Asian production. Aquaculture in Asia contribute more than 80% of an estimated 17-20 million aquaculture farmers in Asia providing livelihoods, food security and export earning power but at the same time there are growing problems with environmental impact from large numbers of small-scale producers and the difficulties in planning and management of further development.

Reporting fishpond yields to farmers

The frustrations encountered when trying to compare technical reports in which fishpond yield figures are reported in a variety of units (e.g., kg/ha, kg/pond, lb/acre, etc.) are familiar to most aquaculturists. However, severe problems may develop when trying to com¬municate research results to other audiences if data are transformed to a hectare basis. The authors gives his own experience in conveying research data to the farmers and the problem encountered.

Protecting small-scale farmers: a reality within a globalized economy?

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.
