    Good news for the Atlantic bluefin but pity the Komodo dragon

    Environment update

    In the deep waters of the North Atlantic, rare sightings are becoming more common: bluefin tuna.

    Fisherman Benking recalls seeing one of the giant fish (which can weigh over 1,000 pounds) off Cornwall.

    “It looked like a giant alien jumping out of the water,” said King, the founder of the seafood company Pesky Fish. “We had to be tuna because we couldn’t catch fish of that size in our ocean.”

    The Atlantic bluefin tuna, previously classified as an endangered species, is now United Nations for Nature Maintenance..

    Four of the seven tuna species on the IUCN list are recovering thanks to better fisheries management and enforcement against illegal fishing.

    IUCN states that catch quotas and protected areas are responsible for the recovery, even though many other marine animals are under threat.

    “Even very commercial species like tuna can turn things around,” said Craig Hilton Taylor, head of the IUCN Red List unit.

    IUCN is a new record of preserved species to commemorate the quarterly rally in Marseille this weekend, one of the largest environmental conferences attended by governments and nonprofits since the pandemic. Announcing the “Green Status” list.

    $ 42 billion

    World Tuna Trade Catch

    Tuna is one of the most valuable types of seafood and is worth about $ 42 billion in annual trade as part of the approximately $ 150 billion annual seafood market. Pew Charitable Trust..

    The number of tuna declined in the second half of the 20th century, and after the measures taken in the 2000s, certain species in certain areas are now beginning to recover.

    “One of the challenges in managing tuna is that it is a highly mobile species,” he said. Mark Jim Ring, Director of The Nature Conservancy’s Large Fisheries Program. “They are also important indicator species as they are heading to the top of the food chain.”

    One of the most successful programs to regulate the tuna fishery took place in the western and central Pacific Ocean, Jim Ring said. The region is sometimes referred to as the “tuna fishery opec” because it produces about half of the world’s canned tuna. Eight countries, including small island states such as Kiribati and the Marshall Islands, have united to limit licenses.

    According to IUCN, the species of Atlantic bluefin tuna, southern bluefin tuna, albacore, and yellowfin tuna have improved since the 2000s. In the case of Atlantic bluefin tuna, the Gulf of Mexico population is declining, but the Mediterranean population has increased by 22% over the last 40 years.

    However, the endangered species of bigeye and bonito have not changed from the previous Red List, and Pacific bluefin tuna are still considered “near-threatened”.

    Among other declining species, more than one-third of shark and ray species are now endangered. “Because marine life is below the surface of the ocean, people tend to think of it as an infinite resource,” said Hilton Taylor. “it’s difficult [for them] To make sure we are losing a lot of marine life. “

    The updated list also includes bad news about Komodo dragons that have moved to endangered species. The world’s largest lizards are under threat of rising sea levels, which invade the islands they live in and reduce their habitat by as much as 30% over the next 45 years.

    One measure being discussed at this year’s IUCN conference is a proposal to protect 30% of the Earth’s land and sea by 2030, but the conference’s recommendations are not binding.
