UNB, Dhaka :
The production of ‘Rui’, a popular carp fish, could be increased by 30 percent through improving its genome within the next six years, according to scientists.
Some fish species that are cultured on an intensive scale like ‘Tilapia’ have seen a significant improvement in growth due to genetic selection, but the natural river population particularly for
carps is used as the only source of ‘good quality’ brood stock for seed production in Bangladesh till now.
WorldFish fish genetic specialist Dr M Gulam Hussain said farmers often allege that Rui fry have not seen the expected growth in their fish farming due to inbreeding of fishes, but this problem will go with the improvement of its genome.
To take advantage of modern genetic selection technology and become independent of reduced natural stocks, WorldFish Bangladesh and South Asia has launched the Rohu (Rui) Genetic Improvement Program (RGIP) under the USAID funded Aquaculture for Income and Nutrition (AIN) Project.
The RGIP has been initiated in two private fish farms in Jessore in July, 2014. But, eggs of three wild Rui stocks have been collected from Halda, Jamuna and Padma rivers during carp breeding season in 2012 and reared in farmer’s ponds, and subsequently juveniles of these stocks were reared until their sexual maturity in two ponds at Mukteshwari Carp Hatchery and Niribili Palli Carp Hatchery in Jessore.
To keep the stocks separate, each fish was marked with a digital passive integrated transponder (PIT) tag. In mid-July, 2014, a total of 210 full sib families were produced through single pair matching from these stocks using complete diallel crossing design.
Later, Gulam Hussain said, trial continues to improve genetic of Rui by selecting crossbreeding like one male rui fish from Halda and female from Jamuna or Padma.
