Acute Toxicity of Triazophos To Common Carp (Cyprinus Carpio) Fry and Their Behavioural Changes
Journal Title: PARIPEX-Indian Journal of Research - Year 2016, Vol 5, Issue 6
Abstract
The study was made to assess the acute toxic effects of Triazophos to common carp (Cyprinus carpio) fry along with the changes in their behaviour during the test. The 24, 48, 72 and 96 h LC50 values of Triazophos to Cyprinus carpio are 3.26, 2.79, 2.59 and 2.04 mg/l respectively. The mortality rate of Cyprinus carpio varied significantly (p<0.05) with the increasing concentrations irrespective of exposure time. On the other hand mortality rate of the fish also varied significantly (p<0.05) irrespective of exposure times (24, 48 and 72 and 96h) at all the doses. The treated Cyprinus carpio showed different irregular behaviours like excess mucous secretion, erratic movement, gulping of air followed by sudden death syndrome (flaring of operculae, convulsion, loss of equilibrium and death) with the increasing concentrations of toxicant and progress of time of exposure. The opercular movement increased significantly (p<0.05) at the lower doses but decreased significantly (p<0.05) at the higher doses at all the exposure times. At a particular concentration the opercular movements increased significantly (p<0.05) at 48 and 72h but with the passage of exposure time, the opercular movement decreased significantly (p<0.05) at 96h.
