Farmed production of some fish - and seaweed
The amount of
farmed seafood
we consume -- as opposed to that taken wild from our waters -- is soaring every year, making
aquaculture
an ever-more important source for many diets, and a response to overfishing.
According to the UN's Food and Agriculture Organization, nearly 99 million tonnes of aquatic animals (fish, molluscs like oysters and mussels and crustaceans like prawns) were farmed around the world in 2023, five times more than three decades ago.
Since 2022, the farming of aquatic animals has been steadily overtaking fishing around the world -- but with large disparities from species to species.

The two biggest sellers on the market in 2023, carp and tilapia, mainly came from freshwater farming, while other widely-consumed fish, like herring, came just from deep sea fishing
Thierry Laugier, a researcher at Ifremer, France's national institute for ocean science and technology, told AFP that fish farmers choose species that grow quickly and with simple requirements, to be able to control the life cycle.
Sales of the most widely farmed fish in Europe, Atlantic salmon, came to 1.9 million tonnes in 2023, 99 per cent of which were farmed.
"We know how to control the ageing or how to launch a reproduction cycle, through injecting hormones," Laugier said.
Asia main producer:
Asia is by far the biggest producer of farmed fish, accounting for 92 per cent of the 136 million tonnes -- of both animal and plant species -- produced under manmade conditions in 2023.
"For carp, it comes down to tradition, it has been farmed for thousands of years on the Asian continent," the Ifremer researcher said.
At the other end of the spectrum, sardines and herring are just fished in the oceans, mainly for profitability reasons as some fish grow very slowly.
"It takes around two years to get an adult-sized sardine," Laugier said.
He said farming of some fish has not yet been started as, "for a long time, we thought the ocean was an inexhaustible resource".
Seaweed:
Little known in the West, seaweed nevertheless accounts for almost a third of world aquaculture production.
Almost exclusively from Asia,
seaweed production
increased by nearly 200 percent in two decades, to 38 million tonnes. It is mainly used in industry, in jellies, pharmaceuticals and cosmetics, the expert said.
He said seaweed also has the major advantage of absorbing not just CO2 in the oceans, but also nitrogen and certain pollutants.
"And from an ecological point of view it is better to farm macroalgae than salmon," Laugier said.

IIT-Kharagpur adopts 3-language formula with stress on Bengali
1 2 3 4 Kolkata: IIT Kharagpur has gone tri-lingual under current director Suman Chakraborty, with an emphasis on Bengali, to promote the importance of regional language and to communicate with non-faculty staff, including housekeepers, gardeners, and maintenance crew, "effectively, without any language barrier". Chakraborty himself has English, Bengali and Hindi on his name plates outside his office and bungalow. He is the first director to put up his name in Bengali. Chakraborty said, "I did it symbolically, to initiate a cultural transformation and to reflect a change in our thoughts, following the three-language formula mentioned in the National Education Policy 2020. I also asked the professor-in-charge of the Rajbhasha Vibhag to ensure there is a proper representation of English, Bengali, and Hindi in all the prominent places of the campus, including auditoriums, buildings, departments, and the Hijli Detention Camp, where there are frequent visitors. " He said, "The Hijli Detention Camp is known as the birthplace of IIT Kharagpur. But it looks odd that the immense contribution of our revolutionaries is not written in Bengali."

Therefore, Bengali must be included in our communications and writings displayed for visitors to know about the campus." The director issued an order saying the tri-language policy will be implemented during foundation st-one laying ceremonies of infrastructural projects during the platinum jubilee celebration, which is set to begin from Aug 18, the foundation day of the institute. "The writings on the foundation stones will reflect the tri-language policy. It will promote our regional language as a medium of instruction and communication, and do away with the linguistic barrier," Chakraborty said.

Coimbatore corporation's plan to expand Vellalore ABC centre comes under a cloud
Coimbatore: AIADMK councillors, animal activists, rescuers, veterinarians, and NGOs have raised objections to the city corporation's allotment of 3 crore to improve and expand infrastructure at its animal birth control (ABC) centre at Vellalore. They have demanded that the estimate be scrutinized by experts. In its council meeting on July 31, the corporation passed a resolution allocating 1.99 crore for the construction of four new kennel bays at the ABC at Vellalore. Additionally, an estimate of 96.3 lakh was also allocated for establishing four operation theatres for stray dog sterilisation at the same centre. Another resolution was passed to allocate 71.5 lakh, with 50% contribution from the Operation and Maintenance Deficit Grants Funds 2025-26, for development work at the Vellalore ABC centre. "It is an open scam and it's high time the corporation holds itself accountable for misusing public money," AIADMK councillor (ward 47) R Prabhakaran said. A volunteer of an NGO associated with the corporation said to date, even basic facilities haven't been provided at the ABC centres run by the civic body. He said, "Even providing a fan is considered a luxury for NGOs. If they accommodate 20 dogs per kennel and plan to have four such kennels, the estimate is too high." by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Is it better to shower in the morning or at night? Here's what a microbiologist says CNA Read More Undo A city-based animal rescuer emphasized that the estimate should be revised. "While there are many loopholes in the accountability of the sterilisation process itself, allocating huge funds for one centre is suspicious. They would just install ordinary tiles, build a compound wall with high fencing, and provide water facilities. Moreover, it won't generate any revenue but only expenses. It's doubtful whether the civic body is genuinely ready to spend on the service. " "It would hardly cost more than 20 lakh per kennel for a 5,000 sq ft area with sophisticated infrastructure like air conditioning," said a private animal breeder who owns a kennel on the city outskirts. Prabhakaran said, "The corporation is not setting up a multispecialty hospital but a facility for stray animals that will be released after 3-5 days. It could rather invest such a huge amount in road patch work, which is the need of the hour." Denying these allegations, corporation commissioner M Sivaguru Prabakaran said, "The corporation plans to construct a huge animal birth control centre at Vellalore with a capacity of 750 stray dogs. We are planning to increase the number of sterilizations. The accusations are baseless, "he said.
