Survival of 5.8 ±1-cm long (l.t.) juvenile perch was studied as influenced by the DBS concentration of 5 mg/l SA in tanks of equal capacities and various surface areas as well as in tanks of the same capacities and surface areas with nettings placed at various depths. Survival time was found to be dependent on the free surface area of a tank, on depth, and on water movement. The results obtained indicate the necessity of taking into account, when determining toxic effects of detergent on aquatic organisms, surface area of a water body, its depth and aeration in addition to the detergent concentration.
