Alaskan fishermen catch rare fish
Joe Chmeleck of Alaska, USA, is a veteran fisherman who goes out to sea every day on his own boat, but with the increase in fishing restrictions, he has recently been able to fish to relieve his boredom, but Joe Chmeleck is not just fishing to survive, so he is not too frustrated.
At the end of last month, while fishing in Alaskan waters, he accidentally caught a fish of almost 30 centimeters, this fish is very brightly colored, basically a dark orange base with bright orange, red and green spots. Joe Chmeleck knows this fish, it's a long-threaded six-threaded fish, but he hasn't caught this marine fish himself, and it doesn't look unusual, right? But when he cut the fish open, he was also stunned: how is the meat of this fish completely bright blue? It's like someone dyed it on purpose.
I haven't heard that long-line six-threaded fish can't be eaten, although I haven't heard that you can eat it. But Joe Chmeleck fried the fish, and he was surprised to find that the blue fish turned white after being fried! And it tastes very much like regular trout. Afterwards, he posted the record of the whole process on his Facebook, and netizens expressed their surprise.
After the Alaska Fish and Game Department noticed the incident, it said that it could not provide recommendations on whether long-line six-threaded fish could be eaten for the time being, because the agency had not succeeded in collecting enough samples to determine its mercury content.
In other words, this fish is too rare.
Today, let's talk about this species.
Long-lined six-threaded fish
Long-line six-threaded fish, also known as fringed greenfish, sea trout, kelp trout, and rock greenfish, are found along the Pacific coast of the Bering Sea in Alaska and stretch into southern California. There are also reports that long-line six-threaded fish can also be found in the northern regions of the Sea of Japan, Hokkaido and the Sea of Okhotsk.
They can live up to 11 years, and the largest individuals can reach a length of 60 cm and weigh around 83 kg. It has orange near-red spots on both sides of its body, dark stripes and spots on its fins, and a blue mouth. Does such mottled color make them easy for predators to spot? In fact, these colors can change color with the surrounding environment, just like octopuses. It only changes to regular color after being captured.
As for why there is a blue-green pigment in the tissues of this fish, scientists are still unclear, but they know that the body of this fish produces biliverphyll, that is, a green bile, maybe the strange color of the fish meat has something to do with this?
According to research by the Oregon Ocean Fund, a marine research foundation, long-line six-threaded fish eat a wide range of diets and eat almost everything they find, including but not limited to invertebrates (such as crabs and isopods) to fish eggs and algae.
Elusive
Long-lined six-lined fish are rare, but not because they are endangered, in fact, scientists don't know how large their populations really are. The reason they are rare is because of their superb camouflage skills and cautious living habits.
The habitat of long-threaded strains tends to be seaweed beds and offshore reefs, and these areas have complex terrain and many crevices, making it difficult to spot hiding long-lined six-threaded fish. Moreover, long-lined six-lined fish will change color according to the natural environment, and they will not stick to an area, but will move their residence according to the situation. For example, when they see such a large movement as humans, they will quickly escape.
They are not social fish, but solitary, which greatly makes it difficult to find them. So for researchers, divers and fishermen, they are very mysterious and elusive.
