A method is described for saving 30% of the world fish catch by producing fishmeal and fish oil replacement products from marine microalgae, the natural source of proteins and oils in the marine food web. To examine the commercial aspects of such a method, we adapt a model based on results of microalgae production in Hawaii and apply it to Thailand, the world's fourth largest producer of fishmeal. A model facility of 111 ha would produce 2,750 tonnes yr^-1 of protein and 2,330 tonnes yr^-1 of algal oil, at a capital cost of $29.3 M. Such a facility would generate $5.5 M in average annual net income over its 30-year lifetime. Deployment of 100 such facilities in Thailand would replace all domestic production of fishmeal, 10% of world production, on ~1.5% of the land now used to cultivate oil palm. Such a global industry would generate ~$6.5 billion in annual net income.

海洋微藻的商业化生产提高了全球渔业和水产养殖的可持续性。

描述了一种通过从海洋微藻中生产鱼粉和鱼油替代产品来节省世界30％的鱼获量的方法，海洋微藻是海洋食物网中蛋白质和油的天然来源。为了研究这种方法的商业方面，我们根据夏威夷微藻生产的结果改编了一个模型，并将其应用于世界第四大鱼粉生产国泰国。模型工厂的面积为111公顷，将产生2750吨yr ^-1的蛋白质和2,330吨yr ^-1的蛋白质藻类油，资本成本为2930万美元。这样的设施在其30年的使用期限内，平均每年可产生550万美元的净收入。在泰国部署100个此类设施将取代目前用于种植油棕的约1.5％土地上的所有国内鱼粉产量，占世界产量的10％。这样的全球产业每年将产生约65亿美元的净收入。
