‘Adopt controlled nursery environment for best yields in shrimp farming’

Mangaluru, May 15: Disease and market prices are the two main problems in shrimp farming, and as India stands poised as the second largest shrimp producer next to China, it is a good time to learn from the mistakes the other southeast Asian countries made when they were on top of the game about five years back, experts said at a high-profile marine sector conference here today.

Speakers at the ‘Advances & Innovations’ in shrimp farming at the fourth edition of Aqua Aquaria India (AAI), hosted by the Marine Products Export Development Authority (MPEDA), suggested that at a time when ‘disease happens in combination’, the way forward in aquaculture is through indoor, totally controlled environments.

“Apart from viruses, we now have to deal with an increase in bacterial infections caused by the warming of oceans. They are harder to control because they do not need animal carriers and can pass through the ocean currents,” said Mr Robins McIntosh, a Thailand-based researcher in the field for three decades. “Aquaculture is about clean water. New technologies must be backed by quality control and surveillance.”

He pointed out that when production was hit in Thailand in 2011, it was technology that brought it up again.

While India is expected to produce 5 lakh MT of shrimp in 2017, the average rate of farm produce survival is only 50 per cent. Productivity is reducing year on year, with the produce being hit by white spot syndrome, which is the single largest pathogen affecting shrimp farming in India.

“This is going to be an era of responsible aquaculture,” said Shri S Chandrasekhar, Area Manager, India & South Asia, INVE Aquaculture, Thailand. “Nursery rearing reduces pathogens. Shrimps are more toxin-resistant and give rise to larger harvests. Thailand and Mexico have reaped the benefits of nursery farming; India could do the same.”

Mangaluru, Dec 7: A rare bamboo shrimp has been rediscovered on mainland India more than 70 years after it was last reported, confirming for the first time the presence of Atyopsis spinipes in the country. The find was made by researchers from the Centre for Climate Change Studies at Sathyabama Institute of Science and Technology, Chennai, during surveys in Karnataka and Odisha.

The team — shrimp expert Dr S Prakash, PhD scholar K Kunjulakshmi, and Mangaluru-based researcher Maclean Antony Santos — combined field surveys, ecological assessments and DNA analysis to identify the elusive species. Their findings, published in Zootaxa, resolve decades of taxonomic confusion stemming from a 1951 report that misidentified the species as Atyopsis moluccensis without strong evidence.

The shrimp has now been confirmed at two locations: the Mulki–Pavanje estuary near Mangaluru and the Kuakhai River in Bhubaneswar. Historical specimens from the Andaman Islands, previously labelled as A. moluccensis, were also found to be misidentified and actually belong to A. spinipes.

The rediscovery began after an aquarium hobbyist in Odisha spotted a shrimp in 2022, prompting systematic surveys across Udupi, Karwar and Mangaluru. Four female specimens were collected in Mulki and one in Odisha, all genetically matching.

Researchers warn the species may exist in very small, vulnerable populations as freshwater habitats face increasing pressure from pollution, sand mining and infrastructure development. All verified specimens have been deposited with the Zoological Survey of India for future reference.

Mangaluru, Dec 7: A 34-year-old fruit and vegetable trader in Mangaluru has reportedly lost ₹33.1 lakh after falling victim to an online investment scam run through a fake mobile app.

Police said the scam began in September, when the victim received a link on Facebook. Clicking it connected him to a WhatsApp number, where an unidentified person introduced a high-return investment scheme and instructed him to download an app.

To build trust, the fraudster asked him to invest ₹30,000 on September 24. The trader soon received ₹34,000 as “profit,” convincing him the scheme was genuine. Over the next two months, he transferred money in multiple instalments via Google Pay and IMPS to different scanner codes and bank accounts shared by the scammers. Between September 24 and December 3, he ended up sending a total of ₹33.1 lakh.

When he later requested a refund of his investment and promised returns, the scammers demanded additional payments, claiming he needed to pay a “service tax” first. Even after he paid a small amount, no money was returned, and the scammers continued pressuring him for more.

A case has been registered at the CEN Crime Police Station.

Mangaluru: In a decisive move to tackle the city’s deteriorating sanitation infrastructure, the Mangaluru City Corporation (MCC) has announced a massive ₹1,200 crore action plan to overhaul its underground drainage (UGD) network.

The initiative, spearheaded by Deputy Commissioner and MCC Administrator Darshan HV, aims to bridge "missing links" in the current system that have left residents grappling with overflowing sewage and environmental hazards.

The Breaking Point

The announcement follows a high-intensity phone-in session on Thursday, where the DC was flooded with grievances from frustrated citizens. Residents, including Savithri from Yekkur, described a harrowing reality: raw sewage from apartments leaking into stormwater drains, creating a "permanent stink" and turning residential zones into mosquito breeding grounds.

"We are facing immense difficulties due to the stench and the health risks. Local officials have remained silent until now," one resident reported during the session.

The Strategy: A Six-Year Vision

DC Darshan HV confirmed that the proposed plan is not a temporary patch but a comprehensive six-year roadmap designed to accommodate Mangaluru’s projected population growth. Key highlights of the plan include:

•    Infrastructure Expansion: Laying additional pipelines to connect older neighborhoods to the main grid.

•    STP Crackdown: Stricter enforcement of Sewage Treatment Plant (STP) regulations. While new apartments are required to have functional STPs, many older buildings lack them entirely, and several newer units are reportedly non-functional.

•    Budgetary Push: The plan has already been discussed with the district in-charge minister and the Secretary of the Urban Development Department. It is slated for formal presentation in the upcoming state budget.
