Synopsis (short abstract) To meet the present demand of large size (about 10 cm) carp fingerling for massive open water stocking in Bangladesh, a modified technology of large size carp fingerling production was demonstrated at four government farms, utilizing locally available facilities and feed ingredients. In the modified system production was 10602292 kg/ha in 3050 days. This rate of production in one cycle is about 4 times higher than the production under the traditional system of large size fingerling rearing. With increased management skills, raising of 45 crops of large size fingerling was found technically feasible. This means that the improved system has the potential for producing 53005500 kg of large fingerling/ha/season. By further improvement of feeding system production can be increased up to 900010500 kg/ha/season by year round multicycle multispecies culture. Against the traditional stocking rates of 40140 prenursed fry/m2, the modified system used only 819 fry/m2, but produced a much hig her biomass of larger fingerling of substantially higher sale value. Production cost of 1 kg fingerling was Tk. 42. Profit over investment was Tk. 25 (60%) in modified system, which is significantly higher than the traditional (Tk. 19/kg i.e. 18%) technology. But the production cost of fingerlings in modified system will be Tk.27/kg when the farmers will use their own stocking material instead of buying. In that case the profit will be 148%.

    Massive stocking of the open waters with nursery raised fingerlings and large-scale expansion of fish culture are two important strategies currently adopted in Bangladesh for increasing fish production. As a matter of policy, large size fingerling is being used for both open water stocking as well as pond aquaculture. Implementation of Asian Development Bank and World Bank sponsored Second and Third Fisheries Projects which has started stocking of fingerling in flood plains for rearing of mark et size fish has created a new demand for carp seed. These new projects stipulate that the number of 1012 cm size fingerling to be released in open waters every year about 400500 million. To achieve this target, private sector should significantly increase its fingerling production for supply to these projects. Moreover, technology of fingerling rearing as used now, in private sector, should be changed because for stocking in the natural waters, the fingerling should be reared at least up to 101 2 cm size. In some areas of the country (particularly in Jessore) private farmers are using effective methods and getting excellent results in producing of small size fingerling in multicrop system, but multicycle production of large size fingerling is not carried out at any part of the country. Moreover, in general, the present fry/fingerling production technology is characterized by inadequate pond preparation, improper manuring and supply of poor quality feed. (Production data of fish seed producers of the country are given in Table 1.) Further, the presently used management methods are not suitable for full utilization of production capacity of broodfish. With the improvement of broodfish preparation methodology the breeding season may be prolonged, facilitating multicycle production of fish seed.

    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.
