Study shows that microalgae assists the stability of small-scale RAS, and that microalgae can be used to manipulate the bacterial community.
recirculating aquaculture systems
Study illustrates the range of salinity options for shrimp production in commercial-scale biofloc systems and found no significant differences in any shrimp production metric.
In the second of a two-part series, Steven Summerfelt discusses various efforts to improve knowledge of closed-containment systems, innovations in fish feed and presents comprehensive concluding remarks.
The recent 2017 Aquaculture Innovation Workshop in Vancouver brought together numerous stakeholders involved in and interested in fish farming – particularly salmonids – in the growing industry of closed-containment systems.
Arab States have substantial natural resources to increase aquaculture production. Several types of systems are readily adaptable and can be implemented relatively quickly.
Wisconsin State Rep. Mary Felzkowski and others are championing aquaculture to grow food production in the state, with a keen interest in recirculating aquaculture systems (RAS).
Biological filters are essential parts of recirculating aquaculture systems that transform toxic fish compounds such as ammonium and nitrite into less-harmful nitrate. The authors tested the convenience and efficiency of three methods for the initial inoculation of aerobic biofilters.
The higher cost of feeds for RAS can be offset by better management, since it is easier to feed frequently and monitor uneaten or wasted feed.
