The impact of deltamethrin on the freshwater fish
Heteropneustes fossilis exposed to two sub lethal
concentrations (0.09 mg/L and 0.18 mg/L) for 30 days on the
activities of endocrine glands viz. prolactin gland, corpuscles
of stannous and ultimobranchial gland. Changes in the
structure of endocrine gland lead significant variation in
inorganic ions concentration Na+, K+, Ca2+ and Mg2+ in brain,
kidney, gills and intestine of H. fossilis. Ca2+/ Mg2+ ATPase
activities significantly decreased in all vital tissues viz.,
brain, gills, intestine and kidney at both the exposure for 30
days in H. fossilis. The ultimobranchial gland exhibited mild
histological changes at lower concentration of deltamethrin.
At higher concentration decrease in staining response of the
cytoplasm, decrease in nuclear volume and degeneration
in the cells were noticed. In corpuscle of stannous sever
changes observed with increase in granulation, vacuolation
and degeneration of cell membrane noticed at higher
concentration of deltamethrin. In prolactin cells sever
changes observed at both the concentration for 30 days
exposure. Significant changes observed in ionic balance
in vital tissues brain > gill> intestine > kidney of the fish
exposed to higher concentration of deltamethrin. Significant
changes noticed in the vital organs viz. Ionic levels in brain,
gills, kidney and intestine. During exposure of deltamethrin
endocrine glands, brain and intestine found to be most
affected tissues of the fish.
