The Texas Parks and Wildlife Division is heralding the excellent news that subsequent week, it is going to inventory its one billionth hatchery-produced saltwater fish, a crimson 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 nicely into the longer term.
Together with a whole lot of different one- to two-inch-long fingerlings, the tiny redfish can 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 with stocked redfish within the late Nineteen Sixties and early 70s, when their populations have been crashing all through the Gulf attributable to business overharvest. By 1975, utilizing strategies that have been pioneered in Florida, Texas scientists had discovered a option to spawn and rear crimson drum in captivity.

This kicked off an formidable 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 have been stocked in San Antonio Bay the next 12 months.
Within the a long time that adopted, biologists additionally discovered easy methods 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 hundreds of thousands of those prized gamefish on the state’s three important hatcheries, that are unfold out strategically alongside the shoreline.

“Texas now shares extra marine gamefish fingerlings than another state,” TPWD deputy assets supervisor Dakus Geeslin tells Outside Life. “Round 80 p.c of the fish we inventory are crimson drum, and about 19 p.c are noticed seatrout.”
Geeslin says the flounder program — which represents the remaining 1 p.c — has solely been underway for about 10 years.
“Flounder are a bit of 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 happy 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 crimson drum (between 10 and 20 million yearly, in accordance with the CCA) go into the bays, the place they intermingle with and assist help wild populations.

In recent times, Geeslin says, TPWD has accomplished extra genetic testing so it will possibly hint the stocked fingerlings and decide how efficient this system has been.
“Within the eight main bays alongside our coast, we are able to see that anyplace from 6 to 17 p.c of grownup redfish through the years have resulted from our stocking work,” he says. “These numbers validate our efforts, and we all know they’re having a optimistic impact on fish populations.”

These stocking have change into much more crucial to assist speckled trout populations in recent times — particularly within the wake of Winter Storm Uri, which killed a minimum of 3.8 million fish alongside the coast, in accordance with TPWD. Seatrout have 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, once we had that massive 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 consider that our stocking quantity enhance is the primary cause for it.”
