Bhubaneswar, August 31 (LocalWire): In a bid to bring the culinary delicacy back on diners’ menu, the freshwater aquaculture scientists have developed a methodology of breeding the fast-disappearing Hilsa in ponds.
The number of Hilsa, which mostly breeds at the confluence of river and oceanic water, has been going down in recent years, with water pollution taking toll of these species that are delicate in nature.
“It’s much sought after in states like Odisha and Bengal. Keeping in view the declining trend of these species, the Central Institute of Freshwater Aquaculture’s regional research centre in West Bengal has undertaken a project to explore captive breeding of these species,” the director of Bhubaneswar-based Central Institute of Freshwater Aquaculture Bindu Pillai said.
“As natural breeding of these species is coming down leading to drop in the catch, the captive breeding is the way out to enhance the yield. The research centre has chalked out a seed production protocol from larvae to fry and from fry to fingerling. The producing seed in the captive pond will be shortly taken up by the regional research centre,” she said while talking to LocalWire.
Pillai further informed that there are multiple factors for the decline in the fish catch. “Besides pollution, over-exploitation of fish concentration zones has led to the disappearance of Hilsa.
Erratic monsoon and lack of uniformity in rainfall might have also led these itinerant Hilsa species to other congenial areas for breeding.
Besides, it has also been found that Hilsa is captured before attainment of the first maturity and do not get a chance to breed even once in the lifetime.
Hence conservation and management of the stock need immediate attention. The captive breeding and seed production will definitely increase the yield of these delicate fish,” she said.
