Flour Bluff Mariculture Lab
To develop super-intensive culture techniques for commercial production of shrimp in Texas and elswhere in the U.S., for human consumption and for live-bait shrimp. Emphasizing environmental stewardship, the Mariculture Laboratory works to minimize environmental impact through use of zero-exchange, closed recirculating aquaculture systems (RAS), while testing feed formulations substituting plant-based ingredients in place of fish meal and fish oil. The Lab focuses on research to promote development of new industries in Texas and the U.S., including production of algae biomass for biofuel, and cultivation and management of native halophyte plants to reduce the impact of aquaculture effluents and for production of biofuel.
- Develop sustainable and cost-effective super-intensive system for the production of food shrimp with no water exchange.
- Develop sustainable and cost-effective technologies for production of live-bait shrimp in Texas and in the U.S.
- Identify algal species for cost-effective production of oil-rich biomass for biofuel and other byproducts, using waste power plant flue gas as the carbon source.
- Develop technology and knowledge to use the halophyte Salicornia as remediation tool of shrimp farm effluent waters, production of biofuel, protein and raw material for the fiberboard industry.
- Produced a record 9.53 kg/m3 with > 94% survival in all four replicates of a small-scale, super-intensive RAS trial with the Pacific White Shrimp, Litopenaeus vannamei, revitalizing interest in shrimp culture in Texas and the U.S.
Conducted research resulting in 1development of sustainable fish meal and fish oil-free shrimp diets.
- Produced F4 generation of viral-pathogen-free (VPF) L. setiferus for grow-out trials and distribution to interested local farmers.
- Obtained funding to design and construct small-scale outdoor raceway system for algae biomass production as part of multi-faceted research program. Work is in progress to identify promising local species while testing CO2 from different sources.
- Set up Salicornia constructed wetland for proof of concept of aquaculture effluent remediation.
