Abstract
Fish is one of the most
important healthiest and cheapest sources of protein in third World Countries.
Many waterbodies (known as bheri) situated in North 24 parganas, West Bengal,
India suffer from severe environmental pollution. The source of pollution in
that area comes from different sources of industrial, sewage, agricultural
activities and petroleum companies which present in that area. Therefore,
studying fishes for heavy metals contamination would benefit individuals living
in a country surrounded by water body. The aim of this study is to determine
and compare the concentration of heavy metals (Lead, Cadmium and Copper) in
different water bodies and fish tissues collected from different aquaculture
ponds of North 24 parganas. The present study is tried to investigate the
effects of physicochemical parameters and heavy metals toxicity on reproduction
of tilapia collected from different sampling sites of North 24 parganas. There
were two groups, one group of samples obtained from seriously polluted
waterbodies and other group of samples collected from those waterbodies that
are not exposed to pollution. The former one treated as a intoxicated group and
later one treated as a control group of our experiment. The results showed that
there was a significant difference between the intoxicated group and the
control group. The histological study of fish organs (Ovary, testes and brain)
was recorded. The testis of the intoxicated group of fish showed some
degenerative changes and decreased number of seminiferous tubules; the ovaries
showed deformation from their normal shapes and severe lymphocytic infiltration
and the brain also showed degeneration of neurons, severe loss of granular
cells. So that our present study will create an awareness in societies on
environmental pollution on edible aquatic animals. We recommended improving the
water quality of these waterbodies and enforcement of law and legislations by
the Government regarding the protection of these waterbodies.
