ICAR-CIBA Scientists Sequence Goldlined Seabream Genome to Boost Aquaculture Potential in India
ICAR-CIBA director Kuldeep K Lal says the genome sequencing would help researchers provide insights into the fish's growth, reproduction and metabolism Scientists at the Central Institute of Brackishwater Aquaculture (CIBA) have sequenced the genome of the goldlined seabream (Rhabdosargus sarba) — 'matti vaayan' in Tamil — in a step aimed at boosting its commercial aquaculture potential. This marine fish, known for its premium white meat priced between `500 per kg and `600 per kg, is in high demand in domestic markets but is not yet commercially farmed.

But we have now standardised the breeding protocols in hatchery conditions. The next step is to use this genomic data for selective breeding programmes, broodstock management, and in enhancing growth, reproduction, and metabolic efficiency,' says lead researcher M Shashi Shekhar, head of CIBA's aquatic animal health and environment division. Though it takes nearly three years for the fish to mature in the wild, it can reach a marketable size of 500g within six to eight months in aquaculture systems. ICAR-CIBA director Kuldeep K Lal says the genome sequencing would help researchers provide insights into the fish's growth, reproduction and metabolism. The goldlined seabream, native to Indian coastal waters, is widely distributed across the Indo-Pacific, from the Indian Ocean and South China Sea to Japan and Australia. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Swelling and internal bleeding in the brain, help this baby Donate For Health Donate Now Undo It is also a euryhaline species, which means it can adapt to varying salinities, making it ideal for brackishwater aquaculture. 'While the fish species has not yet entered the export market and is mainly consumed domestically, it has great aquaculture potential. The genome information helps us move closer to farming it commercially,' says Lal. At present, the fish is harvested from the wild during its breeding season in Nov and Dec. 'We simulate the same salinity and environmental conditions in our hatchery. Once we get the larva, we design specific feeds that can be supplied to farmers,' says Shekhar. The sequencing revealed about 26,900 protein-coding genes. 'Understanding the fish at the molecular level helps us improve traits like growth and disease resistance,' he says. The sequencing was done by isolating the DNA from a fish specimen and sequencing it using standard platforms. CIBA has earlier sequenced the genomes of Penaeus indicus (Indian white shrimp), grey mullet, red snapper, and Karimeen (pearl spot).

Njarakkal Aqua Tourism Centre in state of neglect, footfall slumps
Kochi: The Njarakkal Aqua Tourism Centre, once a vibrant destination that drew domestic and international visitors in large numbers with its engaging farm tourism activities and a scenic appeal, is now in a state of neglect. Abandoned huts, a ruined children's park, deteriorating tin-roofed structures and a defunct Vanchi Island reflect the overall decline, dealing a telling blow to tourism sector in the district. Climatic conditions and govt apathy are pointed out as the main reasons. Located around 14km from the city centre, Njarakkal Aqua Tourism Centre — set up by Matsyafed in 2010 — was a popular hangout spot for Kochi residents, who enjoyed speedboat rides through fish farms, often witnessing leap of fish close to the boats. The daily footfall has dipped from 500 to around 50. At present, the tourism centre mainly offers limited boating facilities — two pedal boats, three rowboats and a solar-powered engine boat. The entry fee is Rs 150, which covers two boat rides and the use of recreational fishing hooks. Visitors used to enjoy the unique fish-leap experience, which too has lost its charm due to a sharp decline in fish population. Damaged bunds around the farm area have also made it difficult to operate speedboats safely. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Learn How To Write Faster for Work (Find Out Now) Grammarly Learn More Undo The centre once featured small huts built in the middle of water, where visitors could enjoy food and relax. Today, all four huts are in a dilapidated state and the service has been discontinued. Although a floating hut was introduced a year ago, it too is damaged now. The children's park is overrun by vegetation. The wooden log bridge connecting the main entrance to the eco-tourism centre is also in a ruined state. The walkway surrounding the farmhouse is no longer usable and visitors are greeted by piles of debris and construction waste left behind following the demolition of small buildings within the centre. "We used to visit this place often. Today we came with family expecting the same charm, but it turned out to be a huge disappointment — there's nothing left to enjoy. No wonder visitors have stopped coming," said Edavanakkad native Raziya. A staff member admitted that footfall halved during Covid and has continued to decline. "There is no attraction left for families, especially those with children. Meanwhile, a nearby private facility offering free boat rides and a toddy shop is drawing away visitors," he said. The food outlet run by Souparnika Swayam Sahaya Sangham is also struggling. "Earlier, over 300 people dined here daily. Now, it's barely 25," said a staff member. Theft of fish by locals is another concern. The authorities recently lodged a police complaint and a probe is under way. The farm primarily cultivates Poomeen (milkfish), Thirutha (grey mullet) and Karimeen (green chromide). It earned Rs 21 lakh in fish sales last financial year. Farm authorities attribute the structures' condition to the area's harsh climatic conditions and lack of govt funding. "The huts were damaged due to flooding from high tide. They need to be rebuilt at a higher elevation. Vanchi Island was also destroyed by high tides. The bunds surrounding the farm are collapsing gradually due to weak soil, which also prevents us from operating speedboats at full speed, as it could further damage them. Reconstructing the bunds alone will require crores," said an official source. A senior Matsyafed official said a Rs 30-crore project is planned across three aqua tourism centres in the state, including Njarakkal. "With this fund, we expect to fully revamp the facilities there," the official added.
