This study focuses on the development of a new value chain in aquaculture, whereby nutrients from fish tank effluents are first encapsulated in algal biomass. Algal biomass will be fed to copepods, which are a good feed for fish larvae. The study offers a cost-effective algal biomass utilization compared to traditional approaches which require resource intensive processes for harvesting.
