Episode 241 (11/24/14): Classifying Fish is Largely a Family Affair

Click to listen to episode (3:24)

TRANSCRIPT


From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of November 24, 2014.

VOICE


If you think there’s something fishy about the “drumstick” just mentioned, you’re exactly right.  That was a description of a Northern Hogsucker, a fish found widely in Virginia’s streams and rivers.  The speaker was Jamie Roberts, a fisheries scientist formerly at Virginia Tech and now at Georgia Southern University, during a May 2013 fish-diversity lesson for the Virginia Master Naturalists’ New River Valley chapter.  This week, as Virginia families gather and focus on turkey drumsticks and other favorite Thanksgiving traditions, we focus on families of a different kind—the ones used to categorize Virginia’s freshwater fish.  Have a listen to Dr. Roberts for about 35 more seconds.

VOICE – 35 sec [listing five main families of freshwater fish in Virginia: minnows, catfish, sunfish and basses, perches and darters, and suckers].

A family is one level of organization used in taxonomy, the science of classifying living things based on their physical characteristics, genetic traits, and evidence of shared evolutionary history.  Fish in 25 families overall inhabit Virginia’s fresh waters.  Those families range from the well-known, such as the catfish family or the family of salmon and trout; to the relatively obscure, such as the Pirate Perch family, which contains only one species.  But as Dr. Roberts noted, most of the over 200 freshwater fish species in Virginia are categorized into just five families.  Let’s close with a quick review of those families, courtesy of several friends of Virginia Water Radio, and accompanied by part of “Bass Fisherman’s Reel,” courtesy of Williamsburg musician Timothy Seaman.

VOICES/MUSIC – 17 sec


Happy Thanksgiving!
