Observations on the Efficacy of Chloramine-T Treatment to Control Mortality in aVariety of Salmonids. Developments in Fish Culture

摘要

Results and observations from 120 chloramine-T treatment trials to controlmortality in a variety of salmonids caused by bacterial gill disease and columnaris are provided to aid fish culturists in determining more effective treatment regimes. When chloramine-T was used at 6, 10 or 15 mg/L, regardless of treatment frequency, efficacy in control of mortality was observed in 56, 65 and 61% of the trials, respectively. When chloramine-T was administered one, two or three times, regardless of treatment concentration, efficacy was observed in 38, 62, and 88% of the trials, respectively.
