Yes, there is, which is very interesting.
Unfortunately, one of the markets is Canada. I think you are aware that the Canadian border patrol has interdicted six shipments of Asian carp at Sarnia, Port Huron, and Windsor-Detroit. However, most of the intensive commercial fishing being done on the Illinois River, and somewhat on the Mississippi River, is oriented towards markets in China. There have been state subsidies for fishermen in Illinois.
I don't know the quantities that are being shipped. The idea is to get the populations down as much as possible so there isn't continued pressure towards the Great Lakes. It appears that there is some success in this, but the carp's ability to reproduce and to consume all of the plankton in the water system is phenomenal. It's felt that in the long term this probably would not work, but in the short and mid term it would be a good technique.
