Reproductive Ecology of Alligator Gar: Identification of Environmental Drivers of Recruitment Success

SEAFWA Journal Volume 4, March 2017

Alligator gar (Atractosteus spatula) exhibit many characteristics of a periodic life-history strategy, including extended longevity, late maturity, high fecundity, and variable recruitment success. Observations of alligator gar spawning events indicate that recruitment in inland waters may be linked to spring and summer flood pulses and the availability of floodplain spawning habitats. However, because data have mostly come from observation and not formal experimentation, it is unknown whether these data represent true requirements or if they simply reflect conditions that were easily...

Fishing Practices and Motivations of Hand Fishers in Texas

SEAFWA Journal Volume 4, March 2017

In 2011, the Texas state legislature legalized hand fishing as a harvest method for cat fish in Texas. Although large cat fish (>600 mm total length [TL]) are expected to be vulnerable to this fishing method, little is known about hand fishers or their harvest practices. To help make informed management decisions and better understand how hand fishers compare to other Texas' cat fish anglers, we surveyed hand fishers to collect information on their demographics and fishing activities. Survey respondents (n = 118) were primarily preexisting cat fish fishermen who already utilized other...

Surveys of Texas Bow Anglers, with Implications for Managing Alligator Gar

SEAFWA Journal Volume 2, March 2015

Increasing interest in conservation and management of alligator gar, a species considered at risk of imperilment by the American Fisheries Society, has made it important to ascertain angling effort and harvest for this species. Bowfishing is believed to constitute the majority of the recreational harvest of alligator gar, yet little is known about bow anglers and their fishing practices. To obtain baseline demographic and fishing information from bow anglers in Texas, we distributed surveys to 173 participants at three Trinity River bowfishing tournaments in 2011. We received 15 completed...

Effects of Water-level Reductions on Littoral Habitat and Recreational Access in Brazos River Reservoirs, Texas

SEAFWA Journal Volume 2, March 2015

Reservoirs provide recreational opportunities along with water supplies, flood control, and hydroelectricity. Although recreational values are often considered in water management plans, reservoir regulators often lack data to evaluate the impacts of operations on fish habitat and recreational access. We partnered with the Brazos River Authority (BRA) and used reservoir bathymetry and side-imaging sonar data to investigate the effects of reservoir water-level changes on littoral habitat characteristics and boat access in 11 BRA reservoirs. Littoral area, coarse substrate, and submerged...

Characteristics of the Paddlefish Fishery at Chetopa Dam, Kansas, 1992 - 2006

SEAFWA Journal Volume 2, March 2015

Paddlefish (Polyodon spathula) angling is popular among Kansas anglers, but limited to a few areas in the state. The most popular fishery, both in terms of angler effort and harvest, is located at Chetopa Dam, a low-water bridge on the Neosho River in southeast Kansas. This fishery, as well as other paddlefish fisheries in Kansas, is only open to recreational angling. As such, maintaining accurate records of recreational harvest are important for management purposes. We summarized data from the Chetopa Dam fishery as part of a mandatory check system for harvested paddlefish from 1992 to...

Description of Bowfishing Tournaments in the Trinity River, Texas, with Emphasis on Harvest of Alligator Gar

Bowfishing may represent a substantial portion of the recreational harvest of alligator gar, but little is known about the relative efficiency of the angling method. To better understand angler effort and harvest rates, we collected data from three Trinity River bowfishing tournaments each year during 2009, 2010, and 2011 (n = 9). Harvest ranged from 2 to 30 alligator gar per tournament with 641 anglers harvesting a total of 134 fish for all years. Mean (± SE) harvest rate (fish h-1) of alligator gar for tournament participants was similar among years at 0.023 ± 0.095 in 2009, 0.018 ± 0...
