Influence of pituitary extract injection on some metabolic parameters in catfish clarias lazera

ABSTRACT

In fish, pituitary hormones have been implicated in the regulation of metabolism beside their effects on gonadal activities. Male and female catfish Clarias lazera were injected with catfish pituitary extract. Samples were taken after two, four and six days of treatment. Serum alkaline phosphatase increased as a result of treatment, while serum glutamic oxaloacetic transaminase [SGOT] and serum glutamic pyruvic transaminase [SGPT] decreased than control fish. The results of total protein and urea revealed a significant decline; while albumin, albumin globulin ratio and creatinine were not affected by treatment
