Description :
Clarias gariepinus is an African catfish, commonly found in most of the regions of India. This is a fast
growing and hardy fish as compared to other indigenous catfishes. In the present investigation,
chromosome number and karyotyping of C. gariepinus are performed. By using phytohemagglutinin
(PHA) activated whole blood cell culture, metaphase chromosomes were isolated and studied. Metaphase
shows that it has 2n=54 number of chromosomes. The chromosomes are further classified as 08
metacentric, 22 submetacentric, 14 subtelocentric and10 telocentric. This study is important for knowing
genomic constitution of this fish as well as it is useful for hybridization with other indigenous catfishes.
