Principal Investigator: Douglas G. Drennan, II
Award Amount: $69,791.00
Abstract:
Commercial-scale marine aquaculture has the potential to close the gap between an increasing demand for high quality seafood products and a marine fisheries near maximum sustainable yields. Intensive recirculation systems are regarded as one critical component of a commercially viable marine… More

Development of Production and Nutrition Characteristics of HISTAR: Beta II Evaluation

Award Year / Program / Phase: 2001 / SBIR / Phase I
Agency: USDA
Principal Investigator: Douglas G. Drennan, II
Award Amount: $0.00
Abstract:
Commercial microalgal production still relies heavily on batch culture methods. Recent investigations have been successful in the development of enclosed photobioreactors, though mostly still at the research level. Due to several factors, production costs of continuous culture methods remain high… More
