Bighead Carp Are Now Present in the St. Croix River. What Does This Mean?
June 1, 2015 - Many anglers and fans of the St. Croix River expected this day to come. Nonetheless, evidence of bighead carp migrating this far into the river system is troubling.
This news might be compared to getting a report of an illness at the doctor's office.
After the shock of the announcement wears off, we are left to grapple with related questions. How bad is it? Can we treat it? If there's nothing we can do, how long before we see symptoms of it spreading? What quality of life can we expect in the years ahead?
The “body” of the St. Croix River has been invaded. A precious and delicate ecosystem is being threatened. How it will be affected (and how it responds) remains to be seen. We are hopeful the fishery can withstand this intrusion with a minimum of disruption and damage.
The situation could be worse. We could be seeing photos of anglers holding silver carp, which are famous for jumping out of the water. Although bighead carp may stay out of sight under the water's surface, they are voracious eaters and prolific breeders. At the very least, their presence is cause for concern.
