Closed-loop systems, tank-based systems such as Re-circulating Aquaculture Systems (RAS) or flow-through systems, provide separation from native species and allow for increased production at aquaculture facilities.
Izinhlelo ezivaliwe, amasistimu asuselwa kumathangi njenge-Re-circating Aquaculture Systems (RAS) noma izinhlelo ezigelezayo, ahlinzeka ngokwahlukana nezinhlobo zemvelo futhi avumela ukukhiqizwa okwandisiwe ezikhungweni zezolimo.
