    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) 2024. The abstracts are subdivided according to the following topics: 1) reducing and preventing aquatic food losses by implementing multidimensional solutions, including better utilization of low-value fish, bycatch, and discards and valorization of by-products (Food loss and waste reduction); 2) enhancing aquatic food product safety and promoting the sustainable consumption of healthy and high-quality aquatic food (Food safety and nutrition); 3) strengthening national, subregional marketing channels and international trade of aquatic food products (Economic sustainability); 4) addressing social and gender issues for inclusive aquatic food value chains (Social sustainability) and 5) understanding and reacting to climate change and environmental impacts affecting the post-harvest fisheries subsector (Environmental sustainability).Cette publication inclut les résumés des articles sélectionnés et qui seront présentés par des experts lors de la réunion du Réseau africain sur la technologie et la sécurité des poissons (ANFTS) 2024. Les résumés sont subdivisés selon les thèmes suivants: 1) réduire et prévenir les pertes alimentaires aquatiques en mettant en oeuvre des solutions multidimensionnelles, avec une meilleure utilisation des poissons de faible valeur, des prises accessoires et des rejets, ainsi que la valorisation des sous-produits (Pertes alimentaires et réduction des déchets); 2) renforcer la sécurité des produits alimentaires aquatiques et promouvoir la consommation durable d’aliments aquatiques sains et de qualité (Sécurité sanitaire et nutrition);3) renforcer les circuits de commercialisation nationaux et sous-régionaux et le commerce international des produits alimentaires aquatiques (Durabilité économique); 4) aborder les questions sociales et de genre pour des chaînes de valeur alimentaires aquatiques inclusives (Durabilité sociale) et 5) Comprendre et réagir au changement climatique et aux impacts environnementaux affectant le sous-secteur de la pêche après capture (Durabilité de l’environnement).

    Food loss and waste (FLW) in aquatic food value chains in the United Republic of Tanzania 2023

    The United Republic of Tanzania fisheries and aquaculture production is dominated by small scale fishers, processors and traders. The fisheries and aquaculture sector provides direct employment to about 202,053 and indirectly more than 4 million people depends on the fisheries related activities such as fish processors and traders, fishing vessel manufacturers and suppliers, fishing gear menders, fish mongers and employees. However, the small scale fisheries (SSF) is challenged with huge Post-Harvest Fish Loss (PHFL) along the supply chain from harvest to the consumption. Although, the United Republic of Tanzania is blessed with many different fish specifies which are characterized by different post-harvest handling and processes, and mixed fish and fish products loss and waste scenarios. This work found limitation of robust impact assessment and interventions to reduce food fish loss and waste for all value chains actors from harvest to consumption. This concludes that there is little information to inform policy makers, and recommend that more robust and harmonized evidences on FLW are needed.

    Food loss and waste (FLW) in aquatic food value chains in Sri Lanka 2023
    Also available in:

    This study aimed to review the overall status of food loss and waste (FLW) along the fisheries value chains in Sri Lanka, enabling the FLW to be well understood and the focus of further FLW assessments and solutions. The value chains of marine and inland and aquaculture sectors were found to be pillars of fisheries production in the country. Yellowfin tuna and skipjack tuna contribute significantly to deep-sea fishing and are crucial for fisheries export earnings. Coastal fisheries made up 58 percent of marine catch and brought a variety of fish, mainly targeting local consumption. The study recommends yellowfin tuna, skipjack tuna, Shortfin Scad or Mackerel fish (Decapterus macrosoma), of marine fisheries and tilapia from inland fisheries and smoked fish industry from processing were recommended for further FLW assessments along with recommendations for FLW reduction solutions in Sri Lanka.
