This is Passport to Texas

Biologists have found Rio Grande silvery minnow eggs in Texas for the first time in over fifty years.

The U.S. Fish and Wildlife Service started a restocking program two years ago. Those fish have now successfully spawned in the Big Bend region of the Rio Grande.

U.S. Fish and Wildlife Service biologist Jason Remshardt says the minnow is important because it tells biologists a lot about the environment it lives in.

The silvery minnow is just sort of an indicator of the river’s health itself. By showing that this fish can survive, it also documents that the river ecosystem itself is healthy, that the habitat for lots of birds and lots of fish is available.

Unfortunately, the minnow’s habitat has shrunk considerably from what it used to be.

Historically the minnow was found in the Rio Grande and the Pecos rivers in New Mexico and Texas all the way down to the Gulf of Mexico. And they hadn’t been found in Texas or Big Bend since the 1950s.

Until now that is. Remshardt says finding the eggs is a step in the right direction, but it doesn’t guarantee success.

The next step is to find young fish and have those fish reproduce on their own. We have to document not just the fish that we stocked, but we have to document the survival and reproduction of several generations.

Rest assured, biologists will be checking up on those baby minnows frequently to make sure they’re doing Okay.

That’s our show… the Sport Fish and Wildlife Restoration program supports our series… For Texas Parks and Wildlife…I’m Cecilia Nasti.
