BIG HEAD AND SILVER CARPS are giving the state authorities a big headache in the Illinois river that connects the Mississippi to Lake Michigan in the USA.
Dozens of videos showing these high-flying carps literally jumping into boats can be found on YouTube.
The two asian carp species were introduced by catfish farmers in the 1970’s to remove algae and suspending matter out of their ponds but many escaped escaped into the rivers during large floods in the early 1990s.
The carps have now become the most abundant species in the river system threatening the local ecology and potential disaster if they start to inhabit the great lakes. To prevent that, the US Army Corps of Engineers, US EPA, the State of Illinois, the International Joint Commission, the Great Lakes Fishery Commission and the US Fish and Wildlife Service are working together to install a permanent electric barrier between the fish and Lake Michigan.
These carps are extremely prolific and consume large amount of food. The can grow up to 100 pounds and a length of four feet and is a common food fish in Asia.
