Fish Genetics, 1

Passport to Texas from Texas Parks and Wildlife and the Sport Fish and Wildlife Restoration Program

Dijar Lutz-Carrillo (DEE-har luhtz—kah-REE-oh) is a geneticist at the A.E. Wood Laboratory in San Marcos.

And we do everything genetics related for Inland Fisheries.

Lutz-Carrillo says geneticists help to answer questions biologists might have about freshwater fish. Some of the questions currently being posed involve DNA “fingerprinting” of largemouth bass.

In terms of the DNA fingerprinting, the questions they’re specifically asking are: is this fish from this reservoir produced in the wild, or produced at the hatchery? And if it’s produced at the hatchery is it with the OWR program—or Operation World Record—and if it’s from that program, who are its parents in that program? So, you’re asking the question who’s your daddy? Yeah, that’s the question (laughs). And your mommy.

Largemouth bass top the list of popular freshwater sport fish…and Parks and Wildlife is attempting to produce world record bass using genetic testing and selective breeding. Loraine Fries (Fr-EYE-Z) is lab manager,

It’s all related to fisheries management and our interest in having the best fishing in the world here in Texas.

We’ll have more on this topic tomorrow.

That’s our show…supported by a grant from the Sport Fish and Wildlife Restoration Program… working to increase fishing, hunting, shooting and boating opportunities in Texas.
