ABSTRACT
Water pollution affects biodiversity harshly. An attempt was made to find out the effect of aquatic pollution on the tissues of the fish, taking two different types of carps from two different areas of West Bengal (Barrackpore in North 24 Parganas and Raiganj in North Dinajpur). The carps used were Labeo rohita (major carp) and Labeo bata (minor carp) and were sampled from two different ponds within 1 km of each locality. The physicochemical parameters of the respective ponds were estimated from which the fishes were collected and comparisons were made. Liver tissues were taken from the fishes for histological and molecular analysis. From histological studies, it was found that there were some irregularities in the liver tissue structures which might be due to water pollution. DNA isolation from fish liver followed by gel electrophoresis was done to check whether water pollution affect the integrity of the extracted genomic DNA of the fish samples.
