Abstract

In the present study was to assessing the Aluminium sulphate toxicity in freshwater fish as Catla catla. Fish samples were exposed to toxicants as aluminium for 72h and their cumulative mortality was calculated in 12 hours intervals. Results were were analyzed by SPSS 20 to obtain number of cumulative mortality and lethal concentrations. LC50 of Catla catla at 72hr was 50mg/L for Aluminium. The mortality at any fixed time increased with the increase in concentration and for a particular concentration mortality increased with the increase in exposure time due to accumulation of toxicants to a dangerous level leading to death. Overall it can be concluded that aluminium sulphate has significant toxicity to Catla catla. This study provides new evidence, using biochemical, oxidative stress markers, hematological, liver markers and histological parameters that exposure to levels of aluminium may be an important factor on fish in the acidified soft waters. It is concluded that the fishes can effectively used as monitors of water quality with respect to metals. Also, it can conclude that biochemical and histological parameters could be ranked as possible biomarkers of pollution.
