Winter 2015: West Michigan Fish Notes
Asian Carp Eaten by Native Fish, New Study Finds
Asian carp are showing up in the diets of some native fish, and the blue catfish is one of the few southern river species big enough to take on adult silver carp. This is encouraging news for big rivers that carp have already invaded, but it does not change the fact that the Great Lakes are at great risk of invasion.

Asian Carp Chili or Carp Burgers, Anyone?
Although Asian carp filets are too bony for most U.S. consumers, boneless minced carp can be used as healthy stand-in for ground beef in some recipes. A recent University of Missouri study found that many people are willing to try Asian carp but only a few have actually done so.

Bass Kleptoparasitism Video
Kleptoparasitism is a feeding strategy that can allow a predator to save energy by stealing its food from another predator. Sometimes anglers catch two fish on a single lure when the second fish attempts to "steal a meal" from the first.
