Abstract :

Abstract[1] Present study was done to survey sodium and potassium fluctuations in blood serum of common carp at different levels of salinity (0, 5, 10, 15 and 20 ppt) for 4 days. 250 of common carp fingerlings with weight average 2.1 gr was selected and transferred into trial tank with different levels of salinity. Blood sampling was performed to cut the caudal peduncle once in every 24 hours and serum was separated with centrifuge machine. Sodium and potassium was measured with flame photometer. Result indicated all of the fingerlings were died in salinities 15 and 20 ppt after 24 hours. The value of blood serum potassium indicated significant difference among salinities in (24-48), (24-72), (24-96), (48-96) and (72-96) hours (P<0.05) and with increasing of salinity decreased level of blood serum potassium in during times. But, for blood serum sodium, there were significant difference among salinities in (24-48) and (24-72) hours (P<0.05). With increasing of salinity, increased level of blood serum sodium after 72 hours (third day) but level of blood serum sodium decreased in fourth day. * Corresponding Authors; Email: [e-mail]
