水生动物蛋白质对全球动物源蛋白质供应的贡献以及水产养殖对捕捞渔业在供应这种蛋白质方面的相对重要性，在与未来水产食品生产及其安全有关的评估和决策中具有相关性。2018年，陆地动物的肉、奶和蛋产生了76，966千吨粗蛋白，而水生动物产生了13，950千吨或15.3%。虽然水产养殖产生了更大吨位的水生动物，但捕捞渔业产生了7，135千吨粗蛋白，而水产养殖产生了6，815千吨。捕捞渔业产量在过去二十年中没有增加，水产养殖产量必须增加，以确保更多和更富裕的人口对渔业产品的需求不断增长。我们根据消费现状估计，水产养殖产量需要从2018年的82，087 Kt增加到2050年的129，000 Kt，以满足更多人口的需求。大约三分之二的有鳍鱼类和甲壳类水产养殖产品是饲料，这些物种的饲料包括鱼粉和鱼油成分。水产饲料需要全球鱼粉和鱼油供应的主要部分。据估计，71.0%的鱼粉和73.9%的鱼油来自渔获物，其余来自水生动物加工废物。据预测，海洋中小型中上层鱼类的捕获量今后不会增加。水产养殖业应减少鱼粉和鱼油的使用，以减少对小型野生鱼类的依赖，这对海洋食物网的完整性和许多沿海地区穷人的粮食安全至关重要。水产养殖饲料中使用的鱼粉和鱼油短缺，如果不能实现减少其在饲料中使用的目标，将导致未来产量的限制。
The contribution of aquatic animal protein to the global, animal-source protein supply and the relative importance of aquaculture to capture fisheries in supplying this protein is relevant in assessments and decisions related to the future of aquatic food production and its security. Meat of terrestrial animals, milk, and eggs resulted in 76,966 Kt crude protein compared with 13,950 Kt or 15.3% from aquatic animals in 2018.While aquaculture produced a greater tonnage of aquatic animals, capture fisheries resulted in 7,135 Kt crude protein while aquaculture yielded 6,815 Kt. Capture fisheries production has not increased in the past two decades, and aquaculture production must increase to assure the growing demand for fisheries products by a larger and more affluent population. We estimated based on status quo consumption, that aquaculture production would need to increase from 82,087 Kt in 2018 to 129,000 Kt by 2050 to meet the demand of the greater population. About two-thirds of finfish and crustacean production by aquaculture is feed-based, and feeds for these species include fishmeal and fish oil as ingredients. Aquaculture feeds require a major portion of the global supply of fishmeal and fish oil. An estimated 71.0% of fishmeal and 73.9% of fish oil are made from the catch with the rest coming from aquatic animal processing waste. The catch of small, pelagic fish from the ocean is not predicted to increase in the future. Aquaculture should reduce its fishmeal and oil use to lessen its dependency on small wild fish important to the integrity of marine food webs and food security for the poor in many coastal areas. Fishmeal and fish oil shortages for use in aquaculture feed will result in a limit on production in the future if goals to lessen their use in feeds are not met.
