    Risk management practices of small intensive shrimp farmers in the Mekong Delta of Viet Nam 2019
    Also available in:
    No results found.

    Viet Nam is one of the top producers and exporters of farmed shrimp. More than 80 percent of the total production comes from small intensive farms, which occupy less than 10 percent of the land area devoted to shrimp farming. It is the main source of income for many rural households in the Mekong Delta provinces. This study examines the characteristics of small intensive shrimp farms and socio-economic status of the farm households, and farming practices and performance that are associated with the strategies and preferences for managing production risks. The analysis was based on primary data from a survey of farms raising the whiteleg shrimp (Penaeus vannamei) conducted in Bac Lieu, Ben Tre and Ca Mau provinces from September 2017 to February 2018.

    Aquaculture development and coordination programme. Fish feed technology. Lectures presented at the FAO/UNDP Training Course in Fish Feed Technology, Seattle, Washington, 9 October - 15 December 1978 1980

    The need for developing suitable feeds based on locally available inexpensive ingredients has been widely recognized. Since lack of trained personnel is the main constraint in the development of fish feed technology in developing countries, the FAO/UNDP Aquaculture Development and Coordination Programme (ADCP) organized a special training course in fish feed technology at the College of Fisheries, University of Washington, Seattle, with a view to forming a small corps of fish feed specialists wh o could then be the focal points for future feed development programmes in their respective countries. The first report of the training course was presented in the report ADCP /REP/79/8. This present volume represents the edited texts of lectures presented by different specialists. Some additional material has been included for more complete coverage of the subject. Together, these texts may be considered to constitute a manual on fish feed technology, even though they were not prepared for that purpose. Twenty-six papers are included, under the general headings: (1) Digestion, physiology and anatomy; (2) nutritional bioenergetics; (3) nutritional biochemistry; (4) feedstuffs; (5) feed formulation; (6) feed manufacturing technology; (7) practical diets; and (8) quality control. Appendices include conversion tables, electrical data, and details on pelletability of selective feedstuffs, pellet die specifications, and equipment requirements for an 8 ton an hour feed mill.

    Promotion of Small-scale Shrimp and Prawn Hatcheries in India and Bangladesh - BOBP/REP/66 1994
    Also available in:
    No results found.

    The shrimp and prawn culture industries in India and Bangladesh still depend on wild fry. However, expanding production and the trend towards intensification, especially in India, will require the development of hatchery industries in these countries. Since the private sector is likely to be the engine for this development, BOBP undertook activities to transfer smallscale hatchery technology as directly as possible to this sector. In India, this took the form of training small-scale entrepr eneurs in tiger shrimp hatchery technology and providing financial support to the Government of West Bengal for the construction of a demonstration hatchery. Of eight trainees in India, one has set up a shrimp hatchery. The shrimp/prawn hatchery in West Bengal was completed, but not put into production. In Bangladesh, a small-scale demonstration freshwater prawn hatchery was set up in Chittagong District. A new hatchery technology, using brine and a simple recirculating biofilter, was found to be feasible. Both government and private sector participants were trained in the hatchery. Direct assistance in the form of training and equipment was given to four private groups. Three of them completed prawn hatchery construction by the end of 1993 and one of them went into production.
