摘要

Economic Aspects of Rearing Larval ASP, Aspius Aspius (L.), and IDE, Leuciscus Idus (L.), In Closed Recirculating SystemsThe profitability of rearing the rheophilic cyprinid fish species asp, Aspius aspius (L.), and ide, Leuciscus idus (L.), in two independent closed recirculating systems was evaluated. The fish were fed live Artemia nauplii exclusively. The rearing of both species was profitable and the financial risk was relatively low. From the point of view of profitability, the purchase price of stocking material was the most significant factor. The price of juvenile asp was 2.5 times higher than that of ide. Rearing larval asp was the most profitable venture.
