Researchers have found that transforming ‘Alaskan pollock’ into fish sticks, imitation crab and fish fillets generates nearly twice the greenhouse gas emissions produced by fishing itself.

Post-catch processing generates nearly twice the emissions produced by fishing itself, which is typically where the analysis of the climate impact of seafood ends, according to the findings, published in the journal Elementa: Science of the Anthropocene.


“The food system is a significant source of global greenhouse gas emissions, and Alaskan pollock is one of the biggest fisheries in the world,” said study researcher Brandi McKuin from Unviersity of California in the US.

“These findings highlight the need to take a comprehensive approach to analysing the climate impacts of the food sector,” McKuin added. “Alaskan pollock is sold as fillets and trim pieces that are used to make products like fish sticks and imitation crab, it’s a huge market,” she said.

Unlike previous studies that have largely overlooked the downstream processing activities associated with Alaskan pollock, this study examined all the components of the supply chain, from fishing through the retail display case.

The results identify “hot spots” where the seafood industry could concentrate its efforts to reduce its climate impacts, said the researchers. For the findings, the research team analysed the climate impacts of transoceanic shipping of exported seafood products.

After the catch, Alaskan pollock are shipped for processing, and in some cases, transported on large container ships that burn copious amounts of fuel, including cheaper, poor-quality bunker fuel that produces high levels of sulfur particles. The researchers noted that sulfur oxides from ship fuels have a climate-cooling effect.

“Seafood products that are exported have a lower climate impact than domestic seafood products,” she said, adding that the climate impacts of shipping will change this year as new regulations for cleaner marine fuels take effect.

“Shipping has a massive influence on climate and a shift to cleaner fuels will diminish the cooling effect from sulfur oxides and increase the climate impact of products that undergo transoceanic shipping, including seafood,” said McKuin. (IANS)

Rihanna was summoned from her seat to accept the honour, with the Prime Minister.

Singer Rihanna was honoured by Prime Minister Mia Mottley at an event which marked Barbados's new status as a republic, which was attended by Prince Charles.

Glaucoma is the second most common causes of blindness worldwide, according to a report by World Health Organisation (WHO). Typically, it occurs in people with over the age of 60 however it can occur at any age. It is also estimated that globally 79.6 million people are affected with glaucoma, half of them being Asian population. While in India, around 11.9 million people suffer vision impairment and out of which 1.2 million cases are due to Glaucoma. It is a growing concern for the population in India. Even after these high numbers, the enormous majority remains undiagnosed, and untreated. More than 90 percent of cases of Glaucoma remain undiagnosed.
