The Colorado River is home to a blue ghost: a fish called the Blue Sucker. It’s a rare and threatened species, and for Mathew Acre, it’s worth the days, weeks and months spent searching for it.

Currently the Blue Sucker status is somewhat unknown in the lower Colorado River, so we are not a hundred percent sure how the Blue Sucker is doing.

Acre is a PhD Student from Texas Tech, and works with a team – that includes Texas Parks and Wildlife biologist Dakus Geeslin – to search for this elusive fish.

So we are about ten miles east of Austin on the Colorado River, we are looking for that faster water, and some type of structure, they are really adept at swimming in fast water, they are great swimmers.

Blue suckers used to be found throughout North America, but dams and poor river quality have led to their dramatic decline.

It’s unique in that it has this really elongated body and it hangs out in these fast flowing waters, shoots, and riffles, that most fish tend to avoid because they just don’t have the energy budget to stay within that riffle.

Join the search for the blue sucker when you tune into the Texas Parks and Wildlife TV series on PBS September 3-9.

Wow, finally! He was in that fast water just where we expected him to be! It just took us a couple of passes through there. You just have to be on your game. That is awesome dude!

Since 1970 Kemp’s Ridley sea turtles have been on the endangered species list. The NPS, TPW and other partners developed a plan to assist their recovery, including the creation of a secondary nesting site [the primary being in Mexico] at the Padre Island National Seashore [PINS].

The numbers are moving in the right direction, but we’re not up to the milestones that are outlined in the recovery plan to even down list the species to threatened, much less to get it off the list entirely.

Dr. Donna Shaver oversees sea turtle science and recovery at Padre Island National Seashore. Dr. Shaver says this year’s annual survey identified 352 nests—from Galveston down to Mexico.

We’ve had more found at PINS and more found in the state of Texas this year than in the last two years combined. So, we’re very excited about it.

Decades of conservation are paying off, or are we just getting better at finding sea the turtle nests?

We do think that we’re seeing an actual significant increase compared to when I started and only one nest would be found every two or three years. And now, here to find more than 300 in Texas during a year, is a big accomplishment for conservation and recovery of the species.

Nature ebbs and flows. A good example is the critically endangered Kemp’s Ridley Sea Turtle. Conservation groups implemented a recovery plan that facilitated exponential growth of the animal’s population.

The population modelers had predicted that exponential increase in the recovery plan would continue – but it did not. So, the expectations written in the plan are not exactly what the population has done.

Even so, Dr. Donna Shaver says the numbers are moving in the right direction. She oversees sea turtle science and recovery at Padre Island National Seashore. One thing that’s helped them is the mandatory turtle excluder devices used by shrimpers.

Turtle excluder devices were developed to shunt sea turtles out of the next while retaining shrimp in the shrimping net. And they’ve been very effective in doing that.

Seasonal area closures have also benefited the turtles.

Texas Parks and Wildlife instituted one when they revised their shrimp fishery management plan close to 20 years ago – taking into account, of course, the responsibilities to help manage the shrimping industry as well as endangered species.

Tomorrow: hard work pays off for the Kemp’s Ridley.

The Kemp’s Ridley Sea Turtle is the world’s most critically endangered sea turtle.

And most nesting in the US by this species occurs in Texas.

Although a native nester in Texas, their primary nesting beach is in Mexico. Dr. Donna Shaver oversees sea turtle science and recovery at Padre Island National Seashore.

The National Park Service along with Texas Parks and Wildlife and other partners had been working since the 1970s to form a secondary nesting colony of endangered Kemp’s Ridley Turtles right here at Padre national Seashore.

They developed the secondary site as a safeguard against potential extinction and other catastrophes. Their population was nearly decimated in the 1940s.

The biggest threats over time – the largescale taking of the eggs from the nesting beach in Mexico. They were sold in markets as a supposed aphrodisiac. There was also loss of nesting turtles taken for food and then also the skin to make leather products. Then, though time, the loss of juveniles and adults incidental to fisheries operations; primarily shrimp trawling, but also some hook and line captures and other types of fisheries.

According to Dr. Randy Simpson, kangaroo rats are…

They’re about the handsomest rodent that you can find.

The problem is, you can’t find them. At least not many of them, anyway. Simpson is Wildlife Biology Program Director at Texas State. During a Texas Parks and Wildlife TV segment airing next week on PBS, graduate students, including Silas Ott, survey the species near the Texas/Oklahoma border.

So, it does seem to be pretty rare geographically. It’s only been found in 11 counties in Texas. And within the past 20 years, it’s only been found in five of those 11 counties.

Ott and his cohorts locate fresh burrows and set traps and cameras. Dr. Simpson.

Are we seeing just the last vestiges of populations that are hanging on? We don’t know. I think that that’s the reason Texas Parks and Wildlife and the U.S. Fish and Wildlife Service want to find that out.

Nathan Rains is a Wildlife Diversity Biologist with Texas Parks and Wildlife. He’s assisting Texas State, and says the agency helped to fund the research through its grant program.

It’s obviously declining. We don’t have a lot of great information on this species, so we’re trying to learn as much as we can. But it’s a species we’re concerned about, and it’s been a concern for awhile.
