Abstract Title: INVASIVE EXOTIC FISH IN TEXAS: RESEARCH AND MANAGEMENT UPDATE
Abstract Text: Exotic fish can be found in a variety of aquatic habitats throughout the state of Texas, from power plant reservoirs to Hill Country springs, as the result of intentional stocking, escapes from fish farms and zoos, and aquarium and bait bucket releases However, few of the many reported species ever become established and not all those that become established have negative impacts and are considered invasive. Unfortunately, several of the species that have successfully established in Texas are highly invasive and have the potential for far-reaching negative impacts. Some of the most problematic are the tilapia and armored catfish that have invaded freshwater and brackish ecosystems from the Hill Country streams to the bayous of Houston and the Lionfish that are increasing to problematic densities in Texas coastal bays, estuaries and marine sanctuaries. Bighead Carp, another worrisome, highly invasive species, have been found in the Red, San Jacinto, and Sulphur Rivers, Big Cypress Bayou, and other isolated locations and, although regulations are in place to prevent their spread, there has been little research on their current status in the state. Invasive exotic fish destabilize shore lines and damage habitat—impacting water quality in the process, and predate or compete with native species, including some listed as threatened or endangered. Aquatic invasive species management efforts by the Texas Parks and Wildlife Dept. have primarily focused on control of aquatic weeds to enhance fish habitats and recreational opportunities. However, efforts are underway to expand research and management work on exotic invasive fish species in Texas in coming years. This presentation will provide an overview of some of the most invasive fish species found in Texas and associated management challenges and an update on ongoing and planned research and management efforts for the current biennium.
