Red Drum and Spotted Seatrout are the most common marine fish anglers seek when fishing coastal habitats in Texas. Classified as game fish by the Texas Parks and Wildlife Department (TPWD), they both have daily bag limits and size limits. Populations of these species fluctuate naturally each year, and abundance depends on several factors. Natural spawning in the bays and nearshore Gulf of Mexico provides young of the year. Two – three years later, these fish recruit into the size anglers target. Mortality, both from fishing and natural causes, must remain less than the overall replacement of young fish into the population, or abundance declines. Anglers are quick to notice reductions in abundance of catchable fish as the number of fish they can catch is highly correlated with the number of appropriately sized fish in the population. The TPWD monitors abundance, through the gillnet assessment program; and angler landings of these and other recreationally important fishes, through the fisheries survey program.
In 2017, Hurricane Harvey damaged boat-access sites, and impacted TPWD’s sampling activities with cancelled surveys, declaration of “non-fishable” days, and a reduction in fall fishing activity. Effects were noticed coast wide, but significantly evident in the Coastal Bend, especially Rockport. Even so, we estimate over 400,000 spotted Seatrout were landed between May and November, 2017, and about 127,000 Red Drum were landed during the same time period (see figure 1).

Based on fall 2017 gill net data, the immediate impact of reduced fishing pressure in the Rockport area was an increased abundance of Red Drum and Spotted Seatrout compared the previous year. Spotted Seatrout were particularly more abundant. Fall 2017 catch per unit effort (CPUE) was 0.41 fish/hr, which is considerably higher than the 10-yr average CPUE of 0.29 fish/hr. Red Drum were trending near the 10-year average.
As of May 2018, fishing pressure is rapidly returning to normal as local hotels and Airbnb’s open up for rent. Generally speaking the fishing has been very good as abundance of the recreationally important species is above average.
The CPUEs for our 2018 spring gill nets (April-May) are as follows:
Spotted Seatrout: 0.86 fish/hr (way up from last year).
Red Drum: 0.93 fish/hr (also higher than the same time period last year).
This is just one example of many types of continuous research being done around the Texas Coastal Bend. Rockport-Fulton is open for business, and the fish are biting!
