This publication written for resource managers aqua culturists and scientists reviews the genetic resources of Indian major carps catla (Catla catla) rohu (Labeo rohita) mrigal (Cirrhinus mrigala) and kalbasu (Labeo calbasu). The review includes information on spawning behaviour and breeding under natural and culture conditions distribution genetic characterization status of genetic resources conservation efforts and hybridization among Indian major carps and with other cyprinids. Research on genetic improvement through selective breeding chromosome set manipulation and genetic engineering in India is reviewed. The status of Indian major carps in Bangladesh Thailand and Viet Nam as well as work in India on cryopreservation and gene banking are also discussed. 76 pp.
