Phosphatase activity and specific methanogenic activity in an anaerobic reactor treating sludge from a brackish recirculation aquaculture system
Anaerobic treatment of high salinity sludge from marine/brackish recirculation aquaculture systems is potentially limited by inhibition of enzymatic activities and cell lysis resulting from high osmotic pressures. To further address these limitations the following investigations were conducted: effect of salinity on phosphatase activity (PA), soluble microbial products (SMP) production, and ...

Salmon aquaculture could incorporate seaweed and sea urchins to reduce nitrogen enrichment
Farming fish together with seaweed and other species could help improve the sustainability of aquaculture and reduce pollution. A new study provides a tool for designing sustainable fish farming systems and calculates their potential to recycle waste. An example of a salmon farming system incorporating seaweed and sea urchins could reduce nitrogen releases to the environment by 45%. Over half of ...

The big shrimp farming debate: clear-water v. biofloc
In recent years, the global market for seafood products, including fresh shrimp, has grown, alongside consumer awareness of and demand for sustainably-sourced produce. This has resulted in a shift from traditional pond culture of shrimp, to closed systems that are closer to market, feature enhanced biosecurity, have a minimal environmental impact, and result in improved shrimp production. A tale ...
