Angry mutant green crab on path of destruction, scientists warn

Scientists warned that green crabs are always known for their bad attitudes, but this kind of new species is crazy and destroys everything.

Surprisingly, the angry crustaceans came from famous and friendly Canada. And it is suitable for ice skating rink from the main quiet coast of the east coast of the United States where a big collection was found.

Green crabs from Nova Scotia are the same species as their main state cousin, but it is possible to accelerate coastal ecosystems by infinite cold and eating soft shells and destroying local catfish.

Quiet crabs are shrinking, and newcomers tend to shake their pliers and boots.

Professor Markus Frederich of the University of New England says,

The crab breed is northern European, more durable than the original cousin of southern Europe and suitable for cold water.

Green crabs are thought to be a scourge of swallowing soft shells and turnips, even if they are quiet. You can destroy seaweed hiding young marine animals.

Lewis Logan, a student at the University of New England, has a troublesome job of identifying crabs captured in the waters of Nova Scotia.

At a distance of 5 meters, breeders (width 10 - 12 cm) are in battle. Those who capture him are not in a hurry to let go.

In the laboratory, researchers released two types of crabs in a haybed of a saltwater pool. Professor Frederick said Canadian invaders cut weeds like Edwards and they said they used scissors to stop marine life in search of evacuation centers.

The first round of research focused on 200 cancers from Canada, and will be announced within the next few months.

Professor Frederick said further research will focus on whether specific genes play an aggressive role or whether it contains factors called mixed survival.

Hybrid theory thinks that cancer can be more aggressive if cancer is established, but we plan to complete later.

Mr. Frederick said that the new contemporary immigrants currently occupy only 2-3% of crabs currently crawling in Maine state, but these figures are certainly increasing.

"This will be another kind of game," he predicted. "It depends on when the crab goes in and out, the main green crab competes."

A good green crab was in New England waters for more than a century, but when the Main Bay warmed up they became a big problem.

In the 1980 's, the crab arrived in Nova Scotia, and the water brought larvae to New England.

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, the real concern that prosperity may be a collapse of the bubble 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.

Even experts do not know much about how the blue crab knows how to deal with them. Those that speed up the cycles that are considered ideal products rather than pests that destroy the environment are either innovation awards by informal funds or public-public partnerships by Bill and others, proposals by Kinderen is. I believe that they and others are time to cooperate with knowledgeable people filling the region. They believe that they can finally solve the problem of overbreeding crab and part of the solution has already appeared.
