The Texas Parks and Wildlife Division is heralding the excellent news that subsequent week, it’s going to inventory its one billionth hatchery-produced saltwater fish, a pink drum fingerling, into coastal waters. This milestone is greater than 40 years within the making as TPWD has labored with marine biologists and conservationists to make sure that Texas bays have wholesome populations of redfish, speckled trout, and flounder effectively into the long run.
Together with lots of of different one- to two-inch-long fingerlings, the tiny redfish will probably be launched into Christmas Bay, situated between Freeport and Galveston. TPWD says it plans to launch these fish on July 31.
Texas first began fascinated by stocked redfish within the late Nineteen Sixties and early 70s, when their populations had been crashing all through the Gulf resulting from business overharvest. By 1975, utilizing strategies that had been pioneered in Florida, Texas scientists had discovered a method to spawn and rear pink drum in captivity.

This kicked off an bold collaboration between TPWD, the Coastal Conservation Affiliation, and American Electrical Energy to construct a large-scale redfish hatchery in Corpus Christi. Operations started there in 1982, and the primary redfish fingerlings had been stocked in San Antonio Bay the next 12 months.
Within the many years that adopted, biologists additionally realized learn how to rear seatrout (often known as speckled trout) and Southern flounder, rounding out what Texans name the inshore Grand Slam. Fisheries managers have since produced thousands and thousands of those prized gamefish on the state’s three essential hatcheries, that are unfold out strategically alongside the shoreline.

“Texas now shares extra marine gamefish fingerlings than every other state,” TPWD deputy assets supervisor Dakus Geeslin tells Outside Life. “Round 80 % of the fish we inventory are pink drum, and about 19 % are noticed seatrout.”
Geeslin says the flounder program — which represents the remaining 1 % — has solely been underway for about 10 years.
“Flounder are somewhat extra concerned in hatching and rearing for stocking that reds or trout,” he says. “However we’ve simply handed the a million flounder stocking quantity, which is one thing we’re pleased with.”
TPWD has additionally been stocking redfish into freshwater lakes, the place they’ll attain heavyweight sizes however can’t reproduce. A pair of energy plant lakes close to San Antonio obtain most of those fish. Nonetheless, the overwhelming majority of the state’s pink drum (between 10 and 20 million yearly, in accordance with the CCA) go into the bays, the place they intermingle with and assist assist wild populations.

Lately, Geeslin says, TPWD has achieved extra genetic testing so it could possibly hint the stocked fingerlings and choose how efficient this system has been.
“Within the eight main bays alongside our coast, we will see that wherever from 6 to 17 % of grownup redfish over time have resulted from our stocking work,” he says. “These numbers validate our efforts, and we all know they’re having a constructive impact on fish populations.”

These stocking have turn into much more vital to assist speckled trout populations lately — particularly within the wake of Winter Storm Uri, which killed at the very least 3.8 million fish alongside the coast, in accordance with TPWD. Seatrout had been among the many hardest hit, with an estimated 104,000 misplaced within the Decrease Laguna Madre alone.
“After the brutally chilly winter of 2021, after we had that huge fish kill, we elevated our seatrout stocking threefold, from 3 to 10 million fry, hoping to handle that trout die-off,” Geeslin says. “Since then, we’ve seen a marked enchancment in our coastal trout inhabitants for that 12 months class, and we imagine that our stocking quantity enhance is the primary motive for it.”
