Deltamethrin induced changes in endocrine glands regulating Calcium & Ionic balance in
Heteropneustes fossilis

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 Mg 2+ 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

intestine. During exposure of deltamethrin endocrine glands,
brain and intestine found to bemost affected tissues of the fish.
