As we reported yesterday, environmental officials began poisoning the Chicago Sanitary and Ship Canal last night in an attempt to prevent Asian carp from reaching Lake Michigan, where experts say they would all but destroy the native ecosystem and force many other species to go extinct. But authorities report that they found no Asian carp in the channel at all during preparations for that poisoning:
The operation to poison thousands of fish in the Chicago Sanitary and Ship Canal is expected to start at dusk, but electrofishing efforts in the canal earlier today failed to find any Asian carp, officials said.
Using huge nets and electrofishing equipment, crews moved through the canal this morning on boats, shocking fish to bring them to the surface. The idea was to rescue any desirable game fish and relocate them before 2,200 gallons of the fish poison rotenone are poured into the canal. The electrofishing didn’t net any Asian carp, and 95% of the fish that were stunned were “rough” fish, said Chris McCloud, spokesman for the Illinois Department of Natural Resources.
It will certainly be interesting to see if they find any Asian carp after the poisoning of the water. If not, they can expect some criticism for overreacting, though environmentalists will undoubtedly argue that given the information available it was best to err on the side of safety and overreact rather than underreact to such a massive threat to the world’s largest freshwater ecosystem.
