Abstract

Sub-Saharan Africa has a high prevalence of food insecurity. Small pelagic fish such as Silver cyprinid (Rastrineobola argentea) which is indigenous to Lake Victoria, can be a nutritious animal sourced food that contributes to a more nutrient dense diet. Potential sustainable catch of Silver cyprinid is estimated at 2 million tonnes yearly, which is four times the amount of the current catch. Whole sun-dried Silver cyprinid was purchased from several markets in Kenya and analysed for nutrient composition, microbial counts and metal content. The results show that utilizing the whole potential catch of Silver cyprinid would provide a significant daily source of vitamin B12, calcium, zinc and iron to the roughly 33 million people living in the Lake Victoria basin. Heavy metal concentration appears to be low, but other food safety aspects like microbial counts call for value chain improvements. We conclude that the underutilized potential of sun-dried Silver cyprinid could substantially contribute to fight malnutrition and food insecurity by providing an affordable nutrient dense animal sourced food to a large number of people. It also highlights the need to improve the value chains to increase the safety of these products.

将小鱼摆上餐桌:未充分利用本地小鱼改善东非粮食和营养安全的潜力

撒哈拉以南非洲的粮食不安全状况非常普遍。小型远洋鱼类，如原产于维多利亚湖的银鲤(Rastrineobola argentea)，可以是一种营养丰富的动物来源食物，有助于营养更丰富的饮食。银鲤的潜在可持续捕获量估计为每年200万吨，是目前捕获量的四倍。从肯尼亚的几个市场购买了整个晒干的银鲤，并对其营养成分、微生物数量和金属含量进行了分析。结果表明，利用所有潜在的银鲤捕获量将为生活在维多利亚湖盆地的大约3300万人提供重要的维生素B12、钙、锌和铁的日常来源。重金属浓度似乎很低，但其他食品安全方面，如微生物数量，需要改进价值链。我们的结论是，晒干的银鲤未充分利用的潜力可以通过为大量人口提供负担得起的营养密集的动物源食品，大大有助于对抗营养不良和粮食不安全。它还强调了改善价值链以提高这些产品安全性的必要性。

期刊介绍： Food Security is a wide audience, interdisciplinary, international journal dedicated to the procurement, access (economic and physical), and quality of food, in all its dimensions. Scales range from the individual to communities, and to the world food system. We strive to publish high-quality scientific articles, where quality includes, but is not limited to, the quality and clarity of text, and the validity of methods and approaches. Food Security is the initiative of a distinguished international group of scientists from different disciplines who hold a deep concern for the challenge of global food security, together with a vision of the power of shared knowledge as a means of meeting that challenge. To address the challenge of global food security, the journal seeks to address the constraints - physical, biological and socio-economic - which not only limit food production but also the ability of people to access a healthy diet. From this perspective, the journal covers the following areas: Global food needs: the mismatch between population and the ability to provide adequate nutrition Global food potential and global food production Natural constraints to satisfying global food needs: § Climate, climate variability, and climate change § Desertification and flooding § Natural disasters § Soils, soil quality and threats to soils, edaphic and other abiotic constraints to production § Biotic constraints to production, pathogens, pests, and weeds in their effects on sustainable production The sociological contexts of food production, access, quality, and consumption. Nutrition, food quality and food safety. Socio-political factors that impinge on the ability to satisfy global food needs: § Land, agricultural and food policy § International relations and trade § Access to food § Financial policy § Wars and ethnic unrest Research policies and priorities to ensure food security in its various dimensions.
