Book excerpt: Grass Carp Ctenopharyngodon idella is used worldwide as a biological control of nuisance aquatic vegetation. Use of triploid Grass Carp in Texas was legalized for stocking on private lands in 1992. Since 1992, landowners seeking to stock triploid Grass Carp must complete a Texas Parks and Wildlife Department (TPWD) permit application, which requires the number of Grass Carp requested, estimated surface area, percent vegetation coverage, and other information on the location and characteristics of the receiving water body. Once applications are received by TPWD, specifics of the application are entered into a database before being approved or denied by TPWD personnel. Purpose of this study was to summarize and characterize the number of permits, number of triploid Grass Carp requested, receiving water body characteristics, and estimated costs in stocking triploid Grass Carp between 1992 and 2020. A total of 30,387 permit applications were submitted, requesting 818,667 triploid Grass Carp of which 793,020 were approved by TPWD. Mean number (± 1 SD) of permit applications per year was 1,048 (± 166), and mean number of triploid Grass Carp requested per year was 28,229 (± 7,881). Trends in permit applications and number of triploid Grass Carp requested were similar between 1992 and 2020. Greater number of requests were for first time, introductory stockings than repeat, supplemental stockings and were from east Texas ecoregions than in central and west Texas ecoregions. Majority of the receiving water bodies were 2.0 ha with 50% submergent vegetative coverage. About 4% of the applications were denied. Estimated cost of stocking ranged between $200 and $400 per ha. Results of this study inform landowners on the practice of triploid Grass Carp as a biological control of nuisance aquatic vegetation but also highlights gaps in information, such as efficacy in controlling aquatic vegetation and the number of triploid Grass Carp stocked, that could benefit TPWD and other natural resource agencies that continue to regulate the stocking of triploid Grass Carp.

Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Book excerpt: Biology and Control of Aquatic Plants: A Best Management Practices Handbook is the fourth edition of a handbook produced by the not for profit Aquatic Ecosystem Restoration Foundation (AERF). The mission of the AERF is to support research and development which provides strategies and techniques for the environmentally and scientifically sound management, conservation and restoration of aquatic ecosystems. One way the Foundation accomplishes this mission is by producing this handbook to provide information to the public regarding the benefits of aquatic ecosystem conservation and aquatic plant management. The first, second and third editions of this handbook became some of the most widely consulted references in the aquatic plant management community. This fourth edition has been specifically designed with water resource managers, water management associations, homeowners and customers and operators of aquatic plant management companies and districts in mind. Our goal in preparing this handbook is to provide basic, scientifically sound information to assist decision-makers with their water management questions.
