The present research and experimental study were conducted out in order to know the rate of bioaccumulation of Chromium (Cr (III) in the gills, intestine, and skin and its acute toxicity to goldfish (Carassius auratus) fingerlings by using Chromium Chloride salt solution. During this experiment goldfish fingerlings were exposed for 96 hours to Chromium chloride salt by preparing a stock solution from 4.6g of greenish chromium chloride salt. The dose of chemicals provides to the fingerlings are increasing day by day, i.e. 4ppm, 6ppm, 8ppm and 12ppm chemical is added to the test group aquarium at 24, 48,72, and 96 hours of experiment respectively. The increase in the concentration of chromium chloride salt solution brought about various morphological and behavioral changes, but no mortality occurs in goldfish fingerlings. When the fish regulatory system responds to the toxicants, it regulates the level of chromium in the fish body. The result shows that the rate of accumulation of chromium in Gills > Intestine > Skin of gold fish. The behavioral change occurs in the fish is that all the fingerlings of goldfish come to the corner of the aquarium and their appetite also decrease due to chemical effect. Out of total 10 fingerlings none of the fish died during the experiment. No mortality occurs because they were subjected to the sub lethal concentration during 96 hours exposure respectively. The above observation conclude that the chromium has toxic effects on goldfish fingerlings, and also on other fish and animals.
