    Project
    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.

    Ethiopia | Availability and utilization of agroindustrial by-products as animal feed | 2018 2019
    Also available in:
    No results found.

    One of the major constraints for the very low production and productivity of livestock in Ethiopia is the poor quality and inadequate quantity of available feed. Agro-industrial by-products (AIBPs) can play an important role in meeting the widely prevalent feed shortage in the country. The AIBPs are usually less fibrous, rich in energy and/or protein contents. They have high digestibility and energy values compared with other classes of feed resources. The major AIBPs produced in Ethiopia include by-products from flour millings, sugar factories, edible oil processing factories, breweries, and abattoirs. These by-products play a vital role in the feeding of livestock mainly in urban and peri-urban livestock systems. The spatial and temporal availability of AIBPs in different parts of Ethiopia has not been quantified. Information on the utilization of such resources is also scanty. Data on availability of these resources is important for developing and using appropriate feeding strategies, improving livestock production and productivity, enhancing the efficiency of AIBPs utilization, decreasing burden on the environment and promoting technologies that further circular economy. This study was aimed at assessing the spatial and temporal availability of major AIBPs and their use as livestock feed. Information on storage and transport of these by-products has also been recorded with the aim to identify ‘hotspots’ at which the wastage takes place, and to suggest ways to reduce it.

    Book (stand-alone)
    African Network on Fish Technology and Safety 2021 - Book of abstracts, 6–9 December 2021 / Réseau africain sur la technologie et la sécurité sanitaire du poisson 2021 - Recueil de résumés, 6-9 Décembre 2021 2022
    Also available in:

    This publication includes the abstracts of the selected papers presented by experts on the occasion of the African Network on Fish Technology and Safety (ANFTS) 2021. The abstracts are subdivided according to the following themes: (a) Reduction and prevention of post-harvest losses by: (i) Improving methods, means and the political and institutional environment conducive to good practices for handling, preservation, processing and packaging of fishery products; (ii) Better utilizing low value fish, bycatch and discards; (iii) Developing by-products; (b) Improving fishery products safety by strengthening inspection and quality control services and systems, certification, eco-labelling, etc.; (c) Improving national, sub-regional marketing channels and international trade of fish and fishery products; (d) Socio-economics, gender and environmental issues related to post-harvest activities; and (e) Addressing the implications of COVID-19 on small-scale fishery value chains. Cette publication inclue les résumés des articles sélectionnés présentés par les experts à l’occasion de la réunion du Réseau africain sur la technologie et la sécurité sanitaire du poisson (ANFTS) en 2021. Les résumés sont sous-divisés selon les thèmes suivants: (a) réduction et la prévention des pertes après capture par: (i) l'amélioration des méthodes, des moyens et de l'environnement politique et institutionnel propice aux bonnes pratiques de manipulation, conservation, transformation et conditionnement des produits de la pêche; (ii) une meilleure utilisation des poissons de faible valeur, des prises accessoires et des rejets; (iii) la création de sous-produits; (b) l’amélioration de la sécurité sanitaire des produits de la pêche en renforçant les services et les systèmes d'inspection et de contrôle de la qualité, la certification, l'éco-étiquetage; (c) l’amélioration des circuits de commercialisation nationaux, sous-régionaux et du commerce international du poisson et des produits de la pêche; (d) les questions socioéconomiques relatives à la parité hommes-femmes et à l’environnement, liées aux activités après capture; (e) la prise en compte des implications de la covid-19 sur les chaînes de valeur de la pêche artisanale.
