Environment update

In the deep waters of the North Atlantic, a rare sight is becoming more and more common: bluefin tuna.

The fisherman principal recalled that he saw a giant fish weighing more than 1,000 pounds off the coast of Cornwall.

King, the founder of the seafood company Pesky Fish, said: “It looks like a huge alien coming out of the water.” “You can’t find a fish of that size in our waters, so it must be tuna.”

According to the latest “red list” update, Atlantic bluefin tuna was previously listed as an endangered species and is now the “least concern” species. International Union for Conservation of Nature.

Due to better fishing management and enforcement of illegal fishing, four of the seven tuna species on the IUCN list are recovering.

The World Conservation Union stated that fishing quotas and protected areas are the reasons for the restoration, although many other marine animals are still threatened.

“We can turn things around, even for highly commercialized species like tuna,” said Craig Hilton Taylor, head of the Red List Division of the World Conservation Union.

The World Conservation Union is launching a new “green status” list to record species that are being saved to commemorate the quadrennial gathering held in Marseille this weekend, which has involved government and non-profit organizations since the pandemic One of the largest environmental conferences.

$42 billion

The fishing value of the global tuna trade

Tuna is one of the most valuable seafood products, with an annual trade volume of about 42 billion U.S. dollars, which is part of a seafood market worth about 150 billion U.S. dollars each year. Pew Charitable Trust.

The number of tuna began to decline in the second half of the 20th century, and after measures were taken in the 2000s, certain species in certain areas are only now beginning to pick up.

“One of the challenges in managing tuna is that they are highly migratory species,” said Mark Zimlin, Director of the Large-scale Fisheries Project of The Nature Conservancy. “They are also an important indicator species because they are at the top of the food chain.”

Zimring said that one of the most successful programs to manage tuna fishing is in the Western and Central Pacific, which is sometimes referred to as the “OPEC of tuna fishing” because it produces about half of the world’s canned tuna. Eight countries, including small island nations such as Kiribati and the Marshall Islands, have joined forces to restrict permits.

According to the International Union for Conservation of Nature, Atlantic bluefin tuna, southern bluefin tuna, albacore and yellowfin tuna species have all experienced improvements since the 2000s. For Atlantic bluefin tuna, although the Gulf of Mexico population has declined, its population in the Mediterranean has increased by 22% in the past 40 years.

However, the endangered status of bigeye tuna and bonito has not changed from the previous red list, and Pacific bluefin tuna is still considered “near threatened.”

Among other species that have fallen in number, more than one-third of sharks and rays are now threatened with extinction. “For marine species, because they are underwater in the ocean, people tend to think of it as an endless resource,” Hilton-Taylor said. “This is difficult (hard [for them] Seeing that we are losing many sea creatures. “

The updated list also contains bad news about the Komodo dragon, which has been moved to the endangered category. The world’s largest lizard is threatened by rising sea levels, which will encroach on the islands where it lives, reducing its habitat by as much as 30% in 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, although the conference’s recommendations are not binding.
