Technical and economic feasibility of food strategies in the hatchery of Cyprinus carpio (Cypriniformes, Cyprinidae) in a recirculating aquaculture system
ABSTRACT In order to optimize the performance and reduce costs in the larviculture of ornamental carp (Cyprinus carpio) in a recirculating aquaculture system, different feeding strategies were tested. For this, two experiments were carried out both under controlled conditions in a greenhouse, in a r...
