Synopsis (short abstract) Fish is a unique source of micro-nutrients. However, many parts of larger fish, such as the head and the bones, are discarded during fish processing despite the high levels of nutrients, and particularly micro- nutrients found in these parts. Thus the promotion and use of fish byproducts to create low-cost, high-quality food could help reduce malnutrition. This practice illustrates the nutritional benefits of incorporating fish byproducts in the diet and suggests recipes to guide their preparation.

    Production of high-value products from the by-products of aquatic food processing 2024

    The processing of aquatic food generates substantial by-products, including animal heads, skins, bones, scales, visceral organs and shells, etc., which can constitute between 30 percent and 70 percent of the whole body of aquatic organisms. These by-products retain numerous bioactive molecules suitable for extraction and application in the nutraceutical, functional food, pharmaceutical, biomedical, cosmetic and material industries, and have the potential to yield high-value products. The transition from aquatic food waste to high-value products presents multiple benefits, including: (i) enhanced human nutrition and health through nutrient and bioactive component provision; (ii) mitigation of environmental pollution by reducing waste; and (iii) improved economic returns because aquatic food waste is transformed into high-value products rather than low-value animal feeds or fertilizers. This guide presents strategic and technical insights by outlining key principles for producing high-value items, including collagen, gelatine, bioactive peptides, chitin, chitosan, chondroitin sulphate, fish leather and fish oil, from the by-products of aquatic food processing.

    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.

    Technical reports - product by product development from Nile Perch (summary table) 1988
    Also available in:
    No results found.
    Since dairy meal is becoming increasingly expensive in Kenya and threatens the fish rearing industry, a systematic study was initiated on the possibility of using aquatic plants and Nile perch silage. The water plants, Azolla niloticus, Lemna perpusilla and Pistia striatotis were tested as a fishmeal for Tilapia zillii and riverine fishes. Low growth rates were achieved in the tilapias. The value of the Azolla protein in fish diet is discussed in relation to dietary requirement in cultured fish. This study demonstrates that the water plant Azolla niloticus together with Nile perch silage as a supplement can be used as a complete diet for cultured fish. It is hoped that the project will help provide detailed information on the nutritional value of the water plant Azolla niloticus and its long-term susceptibility to various inclusions as a complete feed, and conduct least cost feed formulations to make recommendations as to the maximum inclusion levels.
