ABSTRACT
 

Prashanth MS, Sayeswara MA, Dube P, Shwetha A, Prakash G, Hiremath MB., Effect of copper cyanide on behavior and oxygen consumption in Catla catla (Hamilton) carp fish, Onl J Vet Res., 25 (12):902-911, 2021. Mortality % of freshwater fish, Catla catla carp was determined at 96h in groups  of 10 fish exposed to 10 ug/L to 55 ug/L (i.e. 0.010 to 0.05 mg/L) copper cyanide in static water.  Controls were 10 fish kept in freshwater without cyanide. Experiments were duplicated and repeated thrice to confirm results. By static bioassay we found an LC50 at 96 h of 32µg/L. Compared with controls, in fish exposed to cyanide  O2 consumption fell 27% on day 1 and 74 % by day 4 whereas exposed to sub lethal levels declined 22% by day 1, 15% day 7, 7% day 14 and 3.5% by day 21 (P < 0.05). In fish exposed to cyanide we observed increased opercular movement, surface behavior, loss of equilibrium, change in color, mucus secretion, irregular swimming, jerking and aggression Fish occupied ~twice area of controls eventually dying with mouth and opeculars open and light brown gills covered by coagulated mucus. This data suggests that copper cyanide is as toxic to Catla catla as other fish.
