Abstract
Carassius auratus were exposed to gradual salinity concentrations ( tap water 0.1, 4, 8 and 12 gm / l. ) to study the oxygen consumption rate , consumed energy and glucose of plasma . The first concentration was control . Results showed that the oxygen consumption ratewas increased while the salt concentrations were raised . It was 107.19 , 156.91 and 171.12 mg O2 / kg / h. in 4 , 8 and 12 gm / l. of salt concentrations respectively, in comparsion with control ( 85.87 mg O2 / kg / h ) . The consumed energy in same salinities was significantly increased to 0.36 , 0.52 and 0.57 k.cal./ kg / h. respectively, while being 0.29 kcal. / kg /h .in control .The level of blood glucose in plasma was significantly increased in above mentioned salinities to 74.78, 88.92 and 81.67 mg / 100 ml respectively , while in control was 65.12 mg/100 ml.
