This month a 7 foot long nearly 1.2 meters long fish known as the monster’s sturgeon have been caught by the Alpena Fish and Wildlife Conservation Office which was released later.
It is believed to be more than 100 years old. The previous month, it took 3 biologists to pull out a 240-pound fish from the Detroit River, Michigan.
People doubted whether it could be the largest freshwater fish ever in the U.S. but there are other bigger fishes around the world.
As per the geological survey, the largest freshwater fish known is Beluga Sturgeon which is found in Europe and Asia in the Black, Azov, and Caspian seas.
According to the action plan known as Pan-European Action Plan for Sturgeons, made by the World Sturgeon Conservation Society and World Wildlife Fund, The Beluga Sturgeon is as large as about 26 feet and can weigh up to 2.2 tons or 2000 kgs.
The International Union for Conservation of Nature (IUCN) says that this Sturgeon beluga stays at the top of the food chain. They mostly eat the fishes around them but they also can catch birds and also they are capable of killing seals for their food.
An analyst from National Oceanic and Atmospheric Administration (NOAA) said that if one thing keeps growing it would need energy. So the sturgeon Belarus keeps growing. It can live for more than 100 years. And it needs a continuous supply of energy.
Out of 27 species of Sturgeon, Beluga is the largest one. It exists for more than 250 million years. It also existed during the dinosaur era.
The reason behind the bigger growth of Beluga is yet not clear. The reproductive cycles are higher in these species since females produce many eggs as compared to that of smaller fishes. Moreover, their bigger size helps to catch the prey easily.
But these species are listed under the endangered ones. Their eggs are prized for high rates. Hence taking care of these species is important to prevent them from getting extinct.
