Last week Paul Nooijen helped with the installation of a RAS African catfish pre ongrowing system from a German customer. This new system, designed and constructed in our workshop, replaces the current pre ongrowing tanks of the RAS grow out modules that we have previously built. As a result, the current pre ongrowing tanks have become available and can be used to increase production. This 1-pump RAS system consists, among other things, of a trickling tower, drum filter, fibre glass fish tanks with harvesting gates and submerged UV.
