In one day(?), 78 boats managed to net an average of 23 carp each (they
jump when disturbed by a motorboat, but will not bite a lure).

The article says many people say the carp tastes bland, with annoying
small bones, but there IS a market. In the meantime, it's a very bad
menace to the native fish.
