Bighead Carp in Florida, Pt. II

Bob Wattendorf, of the FWC Freshwater Fisheries division, responds to the news item we posted last week, about angler Craig Martin’s bighead carp caught near Destin, Florida:

“One thing to note is we have observed a few large individual bigheads in panhandle rivers for several years—but no reproduction.  They seem to be escapees from fish farms further north.  Several past hurricanes have caused some of those farms to release fish.  Here’s a brief note that was provided to me recently:

 (Boschung & Mayden 2004). 

The Bighead carp (Hypophthalmichthys nobilis) is native to large river systems of eastern China and has been introduced into at least 32 countries since 1949 as a food fish.  It is believed to have first been brought into the United States, along with the silver carp (H. molitrix), in 1972 and reared in Alabama in farm fish ponds from which they have commonly escaped, been sold to the public etc.  They’re reproduction has not been documented in Alabama or Florida waters, but it is believed their impact on native fish populations would be like that described of silver carp in northern US rivers.

Because of their tolerance of brackish waters, the delta areas of our coastal rivers would appear to be prime habitat for both bighead and silver carp.  Both of these species are prohibited under our regulations (see below).  If one is caught the same rule that prohibits release of any nonnative fish (other than peacock bass and triploid grass carp) applies, and they should not be released. We encourage placing any other nonnative fish on ice and consuming or disposing of them properly.

Both species are plankton and algae eaters by filtering the water but I imagine will take a piece of wiggler similar to how grass carp are sometimes caught or in a reaction/irritation bite.
