目前，微藻饲料在水产养殖中的使用量相对较少，主要用于生产贝类和有鳍鱼类的幼体和幼鱼，以及饲养幼鱼所需的浮游动物。蓝绿色螺旋藻被大量用作鱼虾饲料（超过100吨/年），如果生产成本能够降低，甚至可以预测更大的市场。微藻的另一个潜在的大规模应用是培养红球藻以生产类胡萝卜素虾青素，这使鲑鱼肉呈红色。在长期的微藻生物量高的脂质（ω-3脂肪酸）可能会发展。作为鱼油基水产养殖饲料的替代品。在虾池中，本地藻类水华提供了动物的部分饮食需求，但很难最大限度地提高藻类生产力。一个单独的藻类生产系统可以喂养虾，并最大限度地减少对额外饲料的需求。双壳类在其整个生命周期中基本上只以海洋微藻为食。开发这种微藻的养殖技术将使这些动物的陆上生产得以实现，并大大提高产品质量和安全性。
Microalgae feeds are currently used in relatively small amounts in aquaculture, mainly for the production of larvae and juvenile shell- and finfish, as well as for raising the zooplankton required for feeding of juvenile animals. The blue-green alga Spirulina is used in substantial amounts (over 100 t y-1) as a fish and shrimp feed, and even larger markets can be projected if production costs could be reduced. Another potential large-scale application of microalgae is the cultivation of Haematococcus for the production of the carotenoid astaxanthin, which gives salmon flesh its reddish color. In the long-term microalgae biomass high in lipids (omega-3 fatty acids) may be developed. as substitutes for fish oil-based aquaculture feeds. In shrimp ponds the indigenous algal blooms supply a part of the dietary requirements of the animals, but it is difficult to maximize algal productivities. A separate algal production system could feed the shrimps and minimize the need for added feed. Bivalves feed essentially exclusively on marine microalgae throughout their life cycle. The development of cultivation technologies for such microalgae would allow the onshore production of these animals, with greatly improved product quality and safety.
