Rebuilding Texas’ Oyster Habitat

Sampling Gulf Oysters

This is Passport to Texas

Texas has been one of the country’s top oyster producing states since the late 1800’s. Oysterman, Mauricio Blanco has worked the Port Lavaca region for over 30 years.

It’s been a pretty good place over the years. We got so much salt in our blood. That’s what I love to do

But, declining limits on commercial harvests have been signaling a problem for years.

Most oyster reefs are operating on the border of sustainability. Everyone realizes that something needs to be done.

Bill Rodney is a costal ecologist

They’ve been suffering from a number of stressors including drought and hurricanes. On top of that, there’s a lot of fishing pressure being put on.

A historic restoration plan is now in place to rebuild the reefs. A new law requires oyster dealers to recycle their old shell or pay a restoration fee.

The key to restoring the habitat is putting fresh cultch out there. Cultch can be any material that oysters can grow on.

Crushed limestone and recycled oyster shells make an excellent substrate for oyster larva to attach to and grow into spat, which are baby oysters

The site will be closed to commercial harvest for two years, allowing the baby oysters time to grow to adulthood. By the fall, there should be millions of baby oysters growing on this rock out here.

Hatchery Raised Red Drum and Spotted Sea Trout

The CCA Marine Development Center in Corpus Christi produces juvenile red drum and spotted sea trout for release into Texas bays. They do it by tricking wild brood stock.

We put them through a 150-day light and temperature cycle to condense their year down and get them to spawn when we want them to.

Ashley Fincannon is Hatchery Manager

It’s volitional spawning so they are just freely spawning freely in the tanks at night. When the eggs are fertilized, they are buoyant, and they end up at the top of the tanks and end up going in to our egg collectors.

We take those eggs into our incubator room where we hatch them out. They are pretty rapidly developing fish so if we had fish that spawned last night, by this afternoon around six, those fish would be hatching out, they would be feeding on their yolk sack, by three days, they have consumed their yolk sack, their eyes are formed, their mouth is formed, their gut is formed and they are ready to go out and eat.

On the third day, we stock them to our outdoor rearing ponds where we grow them out about 35-40 days where they reach that targeted 35-40-millimeter mark for size at release.

Go to the Texas Parks and Wildlife website to learn more about the hatchery or to plan a visit; search for CCA Marine Development Center.

The “Bird Man” of the Airwaves

This is Passport to Texas

You are listening to Red River Radio. Stay tuned “Bird Calls” is coming up in just a few moments right here on your public radio station.

On the second Tuesday of the month, 10,000 loyal listeners tune in to hear the bird man of East Texas.

I’ve never heard a show on the radio that people can call in and ask questions about birds

Cliff Shackelford is the State Ornithologist for the Texas Parks and Wildlife

[DJ] And we have lines open right now. We’re going to Clair from Shreveport, Claire you’re on line. What’s your question?

[Claire] Hi Cliff, such a big fan.

[Cliff] Hey, great. What’s up?

A lot of people that like watching reality TV ought to turn off the TV and go outside because there’s a reality there that’s so pure, so real, so interesting.

The show took flight after Cliff helped with the station’s annual fund drive.

He does this voluntarily.

Kermit Poling is the General Manager for Red River Radio.

It’s a lot of work for him and there’s travel back and fourth

[Cliff] This is a great partnership for Parks and Wildlife. They just send me over to preach the good word about birds through a radio station that’s already established …I can reach a lot of people in one hour.

For more about the show, “Bird Calls” with Cliff Shackelford, go to redriverradio.org.

Good for the Fish, Good for the River

Guadalupe Bass (Micropterus treculii)

This is Passport to Texas.

Anglers like Courtney and Brandon Robinson are chasing Guadalupe bass, the state fish of Texas.

Fish on! This is why I love catching Guads. They’re little fish but they use the river to fight.

Guadalupe bass once seemed headed for extinction. In the 1970s, state biologists stocked non-native smallmouth bass in Texas rivers. They didn’t expect the smallmouths would cross-breed with native fish. But they did, producing hybrid offspring that were no longer pure Guadalupes.

From 1990s through roughly 2010 almost a million Guadalupe bass were stocked in the river and it drove down the hybridization rates dramatically.

Tim Birdsong once played pro baseball for the Cincinnati Reds. Today he leads Texas Parks and Wildlife efforts to restore river watersheds.

 [The] Guadalupe bass is representative of that whole set of species and some of those are considered imperiled; they may only occur in one river and nowhere else in the world. And it’s a little bit more difficult to get enthusiasm around conserving a minnow or conserving an imperiled freshwater mussel, but what’s good for Guadalupe bass is generally good for those other species.

Learn more about the Guadalupe Bass in July on our podcast Under the Texas Sky. Find it on Spotify, iTunes and other places where you get your podcasts.

Return of the Guadalupe Bass

Guadalupe Bass (Micropterus treculii)

This is Passport to Texas

Dang it! Was that a fish? Yes, He was right in that foam line!

Anglers like Courtney and Brandon Robinson love to fish for Guadalupe bass, named for the Guadalupe River.

Fish on! This is why I love catching Guads, they’re little fish, but they use the river to fight!

The Guadalupe is a stronghold stream for this lone star native, which the legislature dubbed the state fish of Texas in 1989. Decades ago, this little fish seemed destined for extinction. But today it’s coming back.

I want my kids to catch Guadalupe bass. And I want them to be able to do it in the same places that I do.

Chris Johnson leads guided fly-fishing trips. The beautiful rivers the bass live in have a growing army of passionate advocates working to keep these waters clean.

 At end of the day, lovers will always work harder than workers. And if you love what you’re doing, and you love what you’re about, you love your fish, you love your water, you love your state, you love the ground that it flows through, then you’re going to fight to protect it.

Learn more about efforts to restore the Guadalupe Bass and preserve our rivers on our podcast Under the Texas Sky this July. Find it at underthetexassky.org, and wherever you get your podcasts.
