Title: DETERMINATION OF LC50 OF CADMIUM CHLORIDE IN MARINE CATFISH ARIUS ARIUS
Abstract: Cadmium (Cd) is serious pollutants in the aquatic environment. The present study was to determine the toxicity (LC50) of cadmium chloride in a marine Catfish Arius arius. Experimental fishes were collected from Chennai along the Coromandel Coast of Tamil Nadu, India. The fish’s average weights were measured (45g ± 5 g). The fishes were acclimatized in a water tank. Eight groups of experimental fish (containing 10 fishes in each group) were exposed to different concentrations of cadmium chloride i.e. 0, 30, 40, 50, 60, 70, 80 and 90 mg/L respectively and for a period of 96 hrs. The test water Cd concentrations were analyzed before treatments using an Atomic Absorption Spectrophotometer. The physic-chemical parameter were analyzed in these test water like dissolved oxygen, pH, temperature, total hardness and alkalinity. As well as mortality rate of the fishes, were monitored daily. The 96 hrs LC50 value of cadmium cloride for A.arius was found to be 56.4 mg/L.
