Enzymes activities in juveniles and adults of Clarias gariepinus reared in earthen ponds and concrete tanks


Author(s): Achilike NM and Anyanwu PE

Abstract: Clarias gariepinus is the most commonly cultivated fish species in Nigeria, making the country the largest producer in Africa and third in the world, after Thailand and Indonesia. Level of enzyme activities in the plasma of Clarias gariepinus were used to detect tissue damage caused by stress as a result of poor management practices. Sixty-four blood samples were collected from juveniles and adults of catfish reared in six randomly selected fish farms in Lagos State and analyzed with Randox test kits. Results obtained indicated that alkaline phosphatase (ALP), alanine transaminase (ALT), and aspartate transaminase (AST) were significantly elevated (p<0.05) in experimental fish farms when compared to control farms. The study established that amino transaminase and aspartate amino transaminase were higher in fish reared in earthen ponds than concrete tanks as a result of stress, thus indicating renal-hepatic malfunctions.
