Land based abalone culture in re-circulating systems using a recycled freezer container

To minimize environmental problems associated with aquaculture, we wanted to develop abalone culture approach in small scale re-circulating aquaculture system housed in an air-conditioned recycled freezer container. Protein skimmer (PS) removes organic matter from the water before it breaks down int...
