No Thumbnail AvailableProjectThe nutrition and feeding of farmed fish and shrimp; a training manual. 1: The essential nutrients
AQUILA - Support to Regional Aquaculture Activities in Latin America and the CaribbeanAQUILA - Apoyo a las Actividades Regionales de Acuicultura para America Latina y el Caribe
1987Also available in:
No results found.The classification, structure and biological function of the essential nutrients are described; including proteins and amino acids, lipids, carbohydrates, vitamins, minerals, and energy. The quantitative dietary nutrient requirements of fish and shrimp are critically reviewed, and suggestions made for dietary nutrient levels within practical complete diets for carnivorous and omnivorous fish and shrimp species. -

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 report gives an account of shrimp farm development investigations, including small-scale larval culture experiments in which five species were grown to post-larval size from eggs spawned in the laboratory. The results of two experiments to test the efficiency of fertilizer to increase pond production are reported. Production was greater with ammonium sulphate and superphosphate than with superphosphate alone. Application of tea-seed cake at rates of 25 parts per million (ppm) and 10 ppm was effective in eliminating fish from shrimp ponds without damaging the shrimp. Research to produce shrimp in hatcheries should be conducted, but it is important that pond management skills be developed before additional shrimp from hatcheries are provided to traditional type farmers. Suggestions which might assist in improving shrimp farming have been indicated. Supplemental feeding is not considered necessary at this stage of development in the traditional practice of shrimp farming in Thailand. Sufficient food can be supplied by fertilization of pond waters. The most immediate need is to determine what types of fertilizer are appropriate for Thai waters, and their proper rates of application.
