What is the northern snake?

Northern Snakehead is an exotic fish that belongs to the Channidae family and is originally from China, Korea and other countries in the Far East. This long, thin fish attacked many other parts of the world where the population is very unwelcome. It is very customizable to different types of freshwater environment and drastic measures have been taken to eradicate from these areas. The young SnakeHead has brownish colors with a golden tinge, and as she ages, darkens brown with large black spots. It has a widespread anal and dorsal fin along with a short tail. Northern snake with his flattened scaly head and a large mouth really resemble a snake.

Snake heads grow rapidly and achieve maturity at the age of two years. They are very fertile and women can lie up to 100,000 eggs every year. In their native environment, one is formed at the beginning until mid -summer. The hungry young snake heads feed on insects, zooplankton and small crustaceans continuously. As they grow, they become insatiable predators, eat fish and ŽÁby, as well as birds and small mammals.

These fish can acclimatize to a wide range of temperatures and living conditions. Unlike most other fish, northern SnakeHead can survive from water for four days. When they throw themselves into the mud, they can last much longer. They also have a unique characteristic that they will be able to travel on the ground by circling their bodies. All these factors make it difficult for the northern snake to completely remove from the areas that have attacked.

In the past, these fish have been sold in shops for pets and on Asian fish markets. It is assumed that they have been brought to the US for these purposes, but their value of commercial fish determined, as their destructive nature became more clear. The northern snake of the head began to attack the US waters in the middle of the age of 70 and continued to infiltrate other parts of the world. Not only are they pulling out and overtaking native species, but they also kill them for food.Importing these unpleasant fish is now prohibited without permission of American service for fish and wildlife.

Aggressive measures are taken to kill all and all northern snake fish living in American waters. Several types of herbicides have been introduced into the northern snake -infested areas, but this has a disadvantage also killing of the original fish. Fishermen were encouraged to catch and kill any of these invasive fish they encounter.
