Canada: Angry Mutant Green Crabs Eating Ecosystems Faster

This active rookie currently occupies only 2% to 3% of the number of the main provinces of Aeyangi, and these populations may change as they move south.

According to the survey, Canadian Ao-gani pose a serious threat to the ecosystem by eating clams and destroying local Alfalfa.

Crustaceans originating from Nova Scotia but originally from northern Europe are more aggressive and destructive than their immediate family and are found in the main waters

Markus Frederich, professor at the University of New England, pointed out, "What we see is this crazy aggression."

Professor pointed out that crabs are harder than main relatives and are more likely to adapt to cooler water, but they are genetically different because they belong to the same species.

"This will be a completely different game," Frederick said. "It is a problem when crabs entering and leaving more crabs competing in Maine have added." The only thing we can do is to learn how to live with it. "

This active rookie currently occupies only 2% to 3% of the number of the main provinces of Aeyangi, and these populations may change as they move south.

Researchers who are conducting the next research monitored 200 Canadian green crabs, hoping to determine whether the vitality of certain genes or hybrids is responsible for aggressiveness of crustaceans.

Hybrid vitality can prove that crabs are more aggressive when building themselves, but will become more mellow later

Canadian aogani first entered the United States in the early 19th century and exhausted the number of clams before traveling to Nova Scotia

An angry green crab from Nova Scotia is more angry than their green cousin in Maine and is heading south. According to a study by Professor Marcus Frederick of the University of New England they began to destroy coastal ecosystems in Maine because they ate softer clams and destroyed local weeds. "Green crabs are often confused with local helmet crabs and hairy crabs," the Fish and Wildlife Service writes on its website. "The most notable feature is not color - it can range from red to dark spotted greens - but there are five spines or teeth on each side of the shell - there are three round ear lobes between the eyes, It's a little flat, the width of the shell is much wider than that, rarely exceeding 3.5 - 4 inches. "

Blue crab of North America in the 19th century. They are believed to have arrived at the ballast water of a European ship. However, in recent years, more aggressive and destructive crabs for genetically different European crab ecosystems from the Nova Scotia state of Canada emerged near the coast of Maine. . Maine's fishery is in difficult times in recent years. Although the production of lobsters is booming, there is a real concern that prosperity may collapse the bubble. This is partly due to the pressure of climate change. In addition, the Maine's lobster industry has been heavily hit by current government tariffs and trade wars. Opioid crisis has also affected lobster. Mutant crabs are now invading.

If I had to choose three, I might say Elodea, spotted and zebra mussels and blue crabs. We know that these species can do something about aquatic ecosystems based on the direct experience in 48 states and Canada or their impact. One thing worrying about mussels and crayfish is that despite highly coordinated prevention and outreach activities they are continuing in the western and northern regions. Rob: Intruders can directly affect Alaska's own fishery through predation, competition, disease transmission or habitat change. They do damage to wild native fish and economically important wildlife such as deer susceptible salmon and elk. As invaded plants kill the lake, invading species can also reduce the value of property. Some invading plants and parasites threaten agricultural and forest resources
