Static renewal bioassay tests were carried out to determine the acute toxicity (LC50) of metal cyanides to the Indian major carp Labeo rohita. The 96 hour LC50 value for the sodium cyanide, zinc cyanide and copper cyanide to the fish L. rohita were 0.32 mg/L 0.35 mg/L, and 1.1 mg/L respectively. Among the metal cyanide tested, sodium cyanide is found to be more toxic than the other cyanide complexes. In general behavioral responses of the fishes exposed to cyanide included uncontrolled swimming, erratic movements, loss of balance, moving spiral fashion with sudden jerky movements, vertical movements lying on the sides of the test chamber and rapid flapping of the opercular movements with opened mouth finally settles to the bottom.

Sodium cyanide, is highly contaminating aquatic ecosystems as a toxic pollutant, was investigated in the present study for acute toxicity on freshwater fish Labeo rohita. The toxicity tests were conducted by static renewal bioassay method on the juveniles of fish was evaluated. The LC50 value of sodium cyanide to Labeo rohita was found out to be 320 ?g l-1. One third (106 ?g l-1) and one fifth (64 ?g l-1) of the LC50 value was selected for sublethal studies. Behavioural patterns and oxygen consumption were observed in both (1/3rd and 1/5th) sublethal concentrations (1, 5, 10 and 15 days). Sodium cyanide is highly toxic to the animal tested. Fish behaved irregular, erratic, and dartic movements, by followed hyperexcitability, loss of balance, finally settles to the bottom of the test chamber. A decrease in oxygen consumption was observed in 1/3rd (11.62% and -4.52%) and 1/5th (9.11% and -2.82%) sublethal concentrations. Fish under sublethal concentration were found to be under stress but not fatal.

Post Monsoon Season

In present study attempts has been made to document the fishing crafts and gears which operated in Thirumoorthy reservoir, Tamil Nadu. This investigation revealed, the post monsoon season had higher catch per unit effort of 11kg/boat/day by gillnet fishing and about 20 to 30kg/day in cast net. Catla catla has the dominant fish species and accounted about 58% followed by Cirrhinus mrigala (29%), Labeo rohita (12%) and Cyprinus carpio (2%) against the total landings. However, three species including the Tilapia, Rohu and Mrigala were found to constitute fishery in the cast net with mean CPUE of 20 to 30 kg per day.
