Facts About The Asian Carp

Asian carps were brought in United States as food for other fish. These varieties include silver carp and bighead carp. Asian carps have become a serious problem as these have successfully escaped into waterways and are destroying the native American fish.

Few varieties of Asian carps can grow up to a maximum length of four feet and these fish weigh about 100 pounds. These fish have the capability of eating a prey which is about forty percent of their bodyweight. Due to this, the native plankton eaters, such as paddle fish, starve as they do not get enough to eat.

Ever since the Asian carp managed to enter the Mississippi River, they have multiplied at an enormous rate and are now found in almost all the river tributary system. The biggest problem will arise if they enter into the Great Lakes via canals, and pose threat to the indigenous fish species. To curb this problem, authorities have devised electronic gates which help in stopping the spread of this species of fish. Electronic gates are being set in the waterways mostly near the locks and near the underwater fences which are situated under the water. The gates become the sole entrance to permit the boats to pass. A mild electric current runs through the water, so that fish do not proceed ahead and move backward.

Recently, the sections of the canals which were leading towards the locks besides Great Lakes were poisoned with an aim to kill the fish that reside there. Such a step helped a lot in stemming the growth of the Asian carp, but it is a temporary measure.
