在粮食不安全的地方，野生鱼类提供了不可替代的基本营养来源。渔民捕获成千上万的物种，但水产食品的多样性往往被统一归类为“鱼”，模糊了对哪些物种提供负担得起的，营养丰富的食物的理解。在这里，我们使用2，348种鱼类的渔获量、经济和营养数据，以确定39个低收入和中等收入国家中最实惠和最有营养的鱼类。我们发现，100克鱼的价格占最便宜的日常饮食的10%至30%，在72%的国家中，小型中上层鱼类（鲱鱼，沙丁鱼，鲱鱼）是最便宜的营养鱼类。在撒哈拉以南非洲，营养缺乏症日益严重，小于20%的小型中上层渔获量将满足生活在水体附近的所有儿童（6个月至4岁）的建议饮食鱼类摄入量。确保当地供应和促进野生鱼类消费的对营养敏感的政策有助于解决弱势群体的营养缺乏问题。
Wild-caught fish provide an irreplaceable source of essential nutrients in food-insecure places. Fishers catch thousands of species, yet the diversity of aquatic foods is often categorized homogeneously as ‘fish’, obscuring an understanding of which species supply affordable, nutritious and abundant food. Here, we use catch, economic and nutrient data on 2,348 species to identify the most affordable and nutritious fish in 39 low- and middle-income countries. We find that a 100 g portion of fish cost between 10 and 30% of the cheapest daily diet, with small pelagic fish (herring, sardine, anchovy) being the cheapest nutritious fish in 72% of countries. In sub-Saharan Africa, where nutrient deficiencies are rising, <20% of small pelagic catch would meet recommended dietary fish intakes for all children (6 months to 4 years old) living near to water bodies. Nutrition-sensitive policies that ensure local supplies and promote consumption of wild-caught fish could help address nutrient deficiencies in vulnerable populations.
