I am reading differing information about carp in ponds. A number of internet sites says that carp cannot reproduce in ponds but can reproduce in rivers. The Grass Carp is sterile and cannot reproduce; yet according to the brochure 'Fish Pond Management,' produced by the Illinois Department of Natural Resources, Common Carp can reproduce readily in ponds. Many people say that carp will not hurt the fishing in a pond; but other people say that carp interfere with the spawning process of other species by sucking up the fertilized roe during the eating of underwater vegetation and that the impact on desirable fish populations in dramatic. The reason I started this what that I noticed a baby carp in a pond that I fish year after year. The ranger said these are Grass Carp; so I wonder if a baby sterile Grass Carp was stocked in the Sawhill Ponds near Boulder, CO recently.
