Main fishermen, aiming to reduce the number of invasive green crabs

Before days, amidst reports of large arachnids emerging with cars, driving New York residents mad. Now, another creature is causing fear among fishermen, as they find “shelled” crabs with claws in coastal areas. The state environmental conservation department reported last week that they spotted mitten crabs in the non-native river in the state during the cold season, worrying fishermen. The Department said, “These crabs migrate between saltwater and freshwater, competing with native marine life and disrupting regional habitats.” The post by the department on June 5 on Facebook.

Mitten crabs are a type of invasive species of crab that originated from Eastern Asia. According to the Smithsonian, they first established a population in the 1980s off San Francisco coast, but it took decades for them to reach the East Coast.

According to the New York Department of Environmental Conservation, they first recorded details of these crustaceans in the Chesapeake Bay in the mid-2000s. In May 2007, they found a commercial crab in the Hudson River in New York. The mitten crab is the first recorded in crabs.

In New York, they have not fully understood in what way they will influence their habitat, but they have had their grip on their environment in Europe and San Francisco. Passive, DEC says. Small and aggressive animals, crabbing practices, fishing gears, and fishing equipment are threatened by mitten crabs. To identify them, look for “shelled” claws similar to mature crabs on their pincers. Mitten crabs should not have indistinct claws or a notch between their eyes and the four small bumps in the middle. But if you see one, what should you do? “Do not release it back into the wild!” The Smithsonian says. If you see a mitten crab, remove it from the environment and report it to the state health department. They will encourage anyone to do so and report it to the Bureau of Invasive Species and Ecosystem Health for further action.
