Most of us basically think of goldfish as aquarium fish living in fish tanks, and no one would associate them with a 30-kilogram fish.
But just recently, a 67-pound (about 61-pound) goldfish hit the hot search, and it is by far the largest goldfish in the world.
According to the Daily Mail on November 21, the large goldfish was caught by a British man named Hackett in a fishing farm in France.
According to the staff of the fishing farm, this goldfish is 20 years old and was put into the lake as a fry, and everyone affectionately calls it "carrot".
This time, the goldfish was caught ashore, and the staff found that it is still in good health.
Subsequently, Hackett's actions also made netizens applaud. He did not take the goldfish for himself, but took a photo with the goldfish he caught and released it back into the lake.
Everyone must be curious: "How big can a goldfish grow?" ”
In fact, strictly speaking, this big goldfish is not a goldfish.
It is understood that the goldfish is an Ashkenazi koi, a hybrid of leather carp and koi, and is also a common ornamental fish in ponds. The lake where this large goldfish is located is a bluewater lake in the Champagne region of France, famous for its carp production.
Goldfish is a variant of crucian carp, and koi belongs to the variety of carp. Goldfish generally have a lifespan of about 6-7 years, while koi fish generally have a lifespan of about 60-100 years, or even longer.
Under normal circumstances, an adult koi can grow to 1~1.5 meters and weigh 5-10 pounds.
However, if it is a wild large carp, it is another matter, and there are large carp from a few to hundreds of pounds.
Therefore, this "big goldfish" can live to be 20 years old and weigh 30 kilograms, although relatively rare, but not the only case in the world.
As early as 2019, a man in the United States caught a large goldfish, 14 pounds lighter than the "carrot", which had been the largest in the world before.
Although koi are omnivores and relatively adaptable, they are not resistant to sudden changes in water temperature like goldfish.
If the temperature difference suddenly exceeds 2 °C ~ 3 °C, the koi will be uncomfortable. If the environment is suitable and properly maintained, koi have a longer life; Conversely, if the maintenance is not proper and the growing environment is not suitable, the life expectancy will become short.
Therefore, this big goldfish can live to be 20 years old and is in good physical condition, which shows that the water quality and environment of Fishery Lake are very good.
With such a big fish guarding the fishing ground lake, I believe everyone will have good luck.
