THE INFLUENCE OF OXYGEN CONCENTRATION VARIATION IN WATER ON ITS CONSUMPTION BY RAINBOW TROUT FINGERLINGS (Salmo gairdneri Richardson)

Božidar Kulišić ; PZ "Orlić Markovac" Pastrvsko ribogojilište Knin

Sažetak

A mode of defining free dissolved oxygen concentration in in-flow water which supplies the basins with fish fingerlings, is described. The calculation of oxygen consumption by the fish is also defined. The benefit of regular oxygen contents laboratory tests of in-flow water and oxygen consumption is revealed in actual possibility to burden culture units with fish and consequently, to enable high utilization level of the cultured area.
