No results found.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. -

Also available in:
No results found.The eel culture consultancy for FAO Project HUN/79/001 was carried out from 2 June to 1 August 1980 at the Fish Culture Research Institute (Szarvas). Major objectives of the consultancy were: to review on-going research work on eel culture; to assist the research team involved in developing efficient production technology for the experimental intensive eel-pond system designed in 1976; to develop improved eel diets and to assess the feasibility of developing intensive eel culture in Hungary usin g geothermal energy or warm-water effluents. It has been stated that since 1976 staff of the Institute made considerable progress in raising eel in plastic tanks in the recycling fish rearing plant. However, intensive rearing of elvers was endangered by the lack of additional aeration of the fish tanks. Two new experimental outdoor eel-ponds each 150 m2 were stocked with pigmented eels on 29 May 1980 with a density of 0.2 kg/m2 (about 600 pieces/m2). Through the joint efforts of the consulta nt and the research team involved, the traditional Japanese stagnant water eel culture method was successfully adapted to these ponds in spite of several obstacles caused by delays in construction of the water supply and aeration system. Modified eel diets have been developed using slaughterhouse wastes and an experimental programme was agreed upon to continue testing of these diets. The consultant visited Hortobágy State Farm where an existing concrete pond system and two artesian wells are offering year-round fish culturing possibilities. It has been stated that, with some remodelling of the pond system and installation of an appropriate aeration system, the facility could be used efficiently for eel culture, especially for elver raising. -
No Thumbnail AvailableBook (series)Farm-made aquafeeds 1995
Also available in:
No results found.This book is the proceedings of a meeting held in Bangkok in December 1992 on the use of farm-made feeds in Asia. It contains eleven country reviews of the topic, for Bangladesh, Cambodia, China, India, Indonesia, Malaysia, Nepal, the Philippines, Singapore, Thailand and Vietnam. Nine technical papers are also included. Three are on-farm feed preparation and feeding strategies - for carps and tilapias, for catfish and snakehead, and for marine shrimp and prawns. Five other working papers are on economics, the selection of equipment, feed ingredients, formulation and on-farm management, and supplementary feeding in semi-intensive aquaculture, all directed at farm-made, rather than commercial feeds. The ninth working paper is a regional overview of aquafeeds in Asia. An analysis of the material in the eleven country papers is also presented.
