Abstract

Finfish / Shellfish hatcheries typically use large quantities of single-cell phytoplankton (microalgae) to feed shellfish larvae. Microalgae are enriched with a variety of high-value compounds natural pigments, anti-oxidants, vitamins, minerals, polysaccharide, and so on. Algae production requires hatcheries to commit large square footage and equipment cost to culturing phytoplankton. Additionally, culturing algae requires committing significant labor and other operating costs to maintain algal cultures and equipment. The current microalgal production technologies are not cost-effective and are hindered by various bottlenecks, one of which is the harvesting of microalgal biomass. After cultivation of microalgae on a large scale, there is a need to reduce the volume for concentrating the microalgal cells. The development of microalgae concentrates for feeding larvae provides the opportunity to mitigate significant capital and operational costs.
