SHARK PARK said
In the northern United States, signal crayfish is a very common creature, and you can see one by flipping through a stone. But these creatures, which appear in the rivers and lakes of Scotland, are unwelcome invaders.
Scotland's River Clyde is one of the best fishing spots in the world. One day, mitchell, a fishing enthusiast, received a call from an angler: "I think we are in trouble, you better come and have a look." "He jumped into the car and rushed to the river." I couldn't believe there were so many shrimp in this section of the river. You can step on the shrimp and cross the river. There are too many, and it is impossible not to step on a few. ”
A few decades ago, the North American signal shrimp was introduced to the British water body, and then slowly spread and dominated the north. Mitchell said that at first everyone decided to catch it by hand, and thousands of shrimp could not catch it. Some lobsters even grow to more than 20 centimeters long, no longer like crayfish, almost like large lobsters.
The real problem is not the number and size of the shrimp, but the coincidence of the recipe for the shrimp and salmon, which indirectly starves to death. Mitchell's colleague Ian Miller says that after the shrimp appeared, stoneflies were never seen on the ground again. But stone flies are an important food source for salmon, and without food there is no salmon.
For us, these lobsters are a good delicacy, but the Scottish government believes that if people are encouraged to eat crayfish, there will be a market, so their expansion will be wider. Therefore, it is legal to hunt crayfish in Scotland. The easiest way to kill a crayfish is to stomp it to death with a boot.
So now the question is, sweet and spicy crayfish lovers, visually can protect the river channel of several meters long?
