No results found.This is one of a series of field documents prepared during the course of the UNDP project identified on the title page. The conclusions and recommendations given in the report are those considered appropriate at the time of its preparation. They may be modified in the light of further knowledge gained at subsequent stages of the project. The designations employed and the presentation of the material in this document do not imply the expression of any opinion whatsoever on the part of the Unite d Nations or the Food and Agriculture Organization of the United Nations concerning the legal or constitutional status of any country, territory or sea area, or concerning the delimitation of frontiers. -

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.This report gives an account of penaeid shrimp culture development work including postlarval production, nursery rearing and pond culture. The postlarval culture method was established for Penaeus monodon and P. merguiensis using different types of culture vessels. The total number of postlarvae produced in 1975 was 580 300 and production has increased to over 4 million in 1977; this figure will be rapidly increased in 1978 from induced gonad maturation and spawning. The highest P. monodon postl arvae per brood in a 10 m3 tank was achieved by producing 375 000 with 73 percent survival, and 320 000 with 52 percent survival for P. merguiensis. Mass-culture systems of phytoplankton and rotifers were established for larval food organisms. The particulated soybean curd and rotifers were used for the larval diet to substitute for Artemia nauplii. Artemia will still be needed for a better survival rate. Various types of nursery methods were experimented on formulated diet and on natural food in ponds; the optimal nursery stocking densities were determined. A series of pond culture results indicated that interim fish extermination by using 7 ppm derris root extract was effective. The annual shrimp production in pond projected from preliminary results indicated that 600 kg per ha per year is possible, utilizing natural productivity with the fertilization but no feeding. This phase of the work needs to be repeated. Based on the experiments, recommendations are outlined for f urther work to increase production.
