Abstract
    Many fin-and shellfish depend at some stage in their development on algae as nutrients. It is now a widespread practice to grow algae in light dependent systems and to use them, either directly or in algae/rotifer systems, as feed in aquaculture. However, such algal growth systems are expensive and although they work adequately in relatively small-scale systems, cannot be easily developed to meet the demands of large intensive aquaculture units. The recognition that algae which are important nutritionally in aquaculture can be grown using organic compounds as the source of both energy and carbon, so eliminating the need for light, changes the situation. Algae can now be grown more efficiently in high yield and at lower cost in fermenters. This paper discusses the value in aquaculture of growing and subsequently drying algae so that they may be converted to a stable product which can conveniently be used and stored.
