A study on the quantitative water requirements of red porgies, Pagrus pagrus L. (Pisces: Sparidae), during early on-growing under self-feeding conditions

, : A study on the quantitative water requirements of red porgies, Pagrus pagrus L. (Pisces: Sparidae), during early on-growing under self-feeding conditions. Aquaculture and Fisheries Management 25(7): 741-752

Red porgies (Pagrus pagrus), 70 g, were reared for 56 days under self-feeding conditions in 6 successive compartments of the same raceway and their biological performance was studied in relation to their positioning in the raceway and the quantity of water needed to produce 1 kg of fish. Daily gain of biomass was similar in the first 4 compartments, and decreased in the 5th and 6th. The critical water quantity, below which biological performance was impaired, was 400 msuperscript 3/kg fish.
