Work is underway in Israel to ensure even better RAS-farmed fish

As projections continue for the expansion of global seafood demand and concerns rise over the effects of offshore farming, recirculating aquaculture systems (RAS) and the potential of seafood production on land are more in focus than ever. But although their advantages have been documented extensively, some limiting factors restrict their wider application, such as the inefficient removal of nitrogen and phosphorus compounds, the possible increase in pathogens within biofilters and the generation of off-flavour in fish. These can result in increased production costs and fish health issues that affect growth and survival.
