ABSTRACT

Rohu exhibits a relatively slow growth compared to the other Indian major carps such as mrigal and catla, probably due to inbreeding (Reddy et al., 2001). In order to accelerate the growth rate, a selective breeding program was undertaken in India at the Central Institute of Freshwater Aquaculture (CIFA), Bhubaneswar, in collaboration with the Institute of Aquaculture Research (AKVAFORSK), Norway. Five wild stocks were collected from different Indian river systems, namely Ganga, Gomathi, Yamuna, Sutlej and Brahmaputra, along with the CIFA farmed wild stock. All these five stocks were crossed with each other and the better-growing hybrids were selected by following the family selection method, and the offsprings were studied for their growth performance.
