“…Nonnative Grass Carp and Cuchia have not been previously reported from Cedar Lakes, but there is evidence to suggest that both species may be present in this estuary. The Grass Carp is established in several Texas river systems and is continuing to expand its range in the state (Trimm et al 1989; Elder and Murphy 1997; Hubbs et al 2008) and has been shown to be present in multiple drainages of the Galveston Bay system (Robinson and Culbertson 2005), just north of the sampling area in the current study. Cuchia is established in the Lake Pontchartrain estuary in Louisiana (Jordan et al 2020), and self‐sustaining populations have been discovered in urban ponds in the Houston metro area (Best et al 2022).…”

ObjectiveEnvironmental DNA (eDNA) metabarcoding has become an important method for inventorying and monitoring biota in aquatic systems. The Texas Parks and Wildlife Department conducts regular fishery‐independent sampling of biotic communities using traditional sampling gears, such as gill nets and bag seines, in all of the major estuaries of adjacent to the Gulf of Mexico in Texas. Previous studies have shown that eDNA approaches can complement traditional sampling methods.MethodsWe compared fish community structure data in the Cedar Lakes estuary system obtained with traditional sampling gears with data obtained using eDNA sampling using a small sequence of mitochondrial 12S ribosomal RNA gene and a validated taxonomic reference file.ResultFor spring and fall of 2022, eDNA metabarcoding detected a larger number of species than either bag seines or gill nets. Species richness detected via eDNA in two seasons in a single year was comparable with the species richness of agency’s historical record based on traditional gears for Cedar Lakes.ConclusionSeasonal and spatial variation in species richness was similar between traditional and eDNA sampling; however, eDNA metabarcoding allowed detection of several species that would be difficult or impossible to capture with either bag seines or gill nets. We observed two limitations of eDNA metabarcoding. Read depth was not a good index of relative abundance, which limits our ability to infer relative biomass using single samples. Secondly, we observed detection bias in our eDNA results. Specifically, eDNA failed to detect two species of elasmobranchs present when water sampling was performed and eDNA also performed poorly compared to traditional sampling gears for some species of bony fishes. Despite these limitations, eDNA metabarcoding proved to be an efficient and cost‐effective alternative and compliment to traditional fisheries sampling gears for fishery‐independent monitoring of community structure and composition in estuaries of the Gulf of Mexico.

“…Within the United States, grass carp are known to reproduce naturally in large parts of the Mississippi River Basin [2], the Trinity River in Texas [8], and in the Lake Erie Basin in Ohio [9]. They often inhabit lakes and ponds, but they must broadcast their semi-buoyant eggs into flowing water [7].…”

Grass carp Ctenopharyngodon idella, is an herbivorous fish originally brought to North America from Asia in 1963 to control nuisance aquatic vegetation. Since their arrival, detrimental alterations to aquatic ecosystems have sometimes occurred in waterways where they were initially stocked and into which they have escaped. The movements of grass carp from lentic systems into tributaries required for spawning is poorly understood, and understanding environmental conditions associated with upstream migrations may aid in management of the species. We stocked 43 fertile diploid and 43 sterile triploid grass carp implanted with acoustic transmitters into Truman Reservoir, Missouri, USA between January 2017 and October 2018 to characterize movements during spring and summer when spawning conditions occur. Twenty fish (11 diploid/9 triploid) exhibited upstream migration behavior in the Osage River, a major tributary, in 2018 and 2019. Migration primarily occurred in April and May, during high discharge events associated with increasing river stage when water temperatures were between 15 and 28°C. Observed migrations ranged from 3.0–108 river km in length, and six individuals were observed making multiple upstream migrations in one season. Eleven fish initiated upstream migrations while in the lentic main body of the reservoir. These findings provide some evidence for upstream migrations by diploid and triploid grass carp as well both lake and river residents. Evidence of similar upstream migration behavior by both diploid and triploid grass carp suggests that triploids may be suitable surrogates for diploids for study of movement ecology. Removal efforts in tributaries targeting periods of increasing river stage during spring may provide the best opportunity of encountering large concentrations of grass carp.

We developed a three‐step management strategy for hydrilla Hydrilla verticillata in five Piedmont reservoirs operated by Duke Energy Corporation. This strategy involves (1) early detection of hydrilla, (2) use of registered herbicides for plant suppression along with stocking 20 triploid Grass Carp Ctenopharyngodon idella per surface acre of infestation, and (3) maintenance stocking of triploid Grass Carp to prevent hydrilla regrowth from tubers. Following this strategy, hydrilla in the water column was eliminated within one calendar year after Grass Carp introduction in four out of five reservoirs. This suggests that integrating herbicide applications with stocking Grass Carp largely eliminates the multiyear lag effect normally associated with using Grass Carp alone. A maintenance density of at least one triploid Grass Carp per eight surface acres of the reservoir prevented hydrilla regrowth except for a brief and minor reinfestation in one of five study reservoirs. This management approach proved successful when hydrilla coverage was as little as 1–3% of the reservoir's surface area. Detecting and controlling hydrilla early during the infestation should reduce the cost of management and perhaps minimize some adverse effects associated with the introduction and use of triploid Grass Carp.Received November 14, 2012; accepted January 15, 2013
