Research OverviewRecirculating Aquaculture Global marine fisheries have exhibited continuous declines in recent years. Although this can be addressed by raising fish in open net pens, one of the major obstacles to the development of marine aquaculture is its interaction with the environment, including the outflow of wastes and pathogens into the marine environment, potential escapes of non-native species, and the potential contamination of fishes by pathogens, toxins or other pollutants in the water. Recirculating aquaculture represents a self-contained, environmentally-friendly solution to all of these problems, because it is...

Research Specialties: Microbial nutrient cycles in marine recirculating aquaculture systems with an emphasis on nitrogen and carbon transformation processes such as nitrification, denitrification, anammox and methanogenesis, and their combined utilization for water recovery and solids treatment. Globally, marine fisheries have exhibited a significant decline in catches during recent years. Over-fishing, pollution and global warming are some of the causes for the looming collapse of fisheries worldwide. Marine aquaculture or fish farming is one of the ways to reduce pressure on these fisheries and allow their recovery, while simultaneously supplying the increasing demand for marine fish and other seafood products. In order to reduce the environmental impact of aquaculture, one approach that is currently promoted is to shift some of the industry operations to inland closed-loop recirculating systems. Such recirculating systems... Complete Information... |
