“…Although our study is limited in scope, our data provide evidence that individuals are able to withstand high velocities and resist displacement or mortality. These results are consistent with other studies which have shown that many riverine fish species are well adapted to large flood events and are able to resist short-term direct impacts of these events (George et al, 2015;Carlson et al, 2016).…”

Development of techniques for assessment of population characteristics of the federally endangered Diamond Darter Austin A. Rizzo Population monitoring is an essential component of endangered species recovery programs. One species for which monitoring is needed is the federally endangered Diamond Darter Crystallaria cincotta. This species was placed on the Endangered Species List in 2013 because of its small range and population size, and because of continued anthropogenic threats to the species' habitat. The Diamond Darter is believed to occur only within the lower 50 rkm of the Elk River in West Virginia. Museum specimens indicate the Diamond Darter was once distributed throughout the Ohio River Basin, but it is now likely extirpated from the Muskingum River, the Ohio River, the Green River, and the Cumberland River drainages. Because of the Diamond Darter's small size, cryptic coloration, nocturnal behavior, and seemingly patchy distribution, along with limitations associated with current sampling methods, the species may appear to be rarer than it actually is. This may have also contributed to its late discovery as a species in 2008. As a result of several of the above-mentioned factors, the Diamond Darter is a much understudied fish with very little known about life history, population size, or current distribution. One problem with monitoring populations of rare and elusive species is detection. Failure to account for detection probability can be a major source of bias in presence-absence and count survey data, potentially resulting in false determination of species absence and underestimation of abundance, respectively. Additionally, if these variables are not accurately estimated, their relationship to associated habitat and environmental variables may also be inaccurate. Ultimately, not accounting for detection probability may lead to misinformed management decisions, which can prove costly for an endangered species. For this study, I sought to develop techniques that would allow for the assessment of population characteristics for this rare, elusive species. In my first chapter, I evaluated the precision and accuracy of photogrammetric length measurements relative to direct board measurements of Greenside Darters Etheostoma blennioides and Variegate Darters Etheostoma variatum. Agreement between board and photogrammetric measurements were high for these species, supporting photogrammetry as a useful method for obtaining length measurements of benthic stream fishes. Consequently, I applied photogrammetry in a field study of the Diamond Darter and assessed length frequency of 199 individuals throughout the sampling season. Based on these data I was able to identify a single cohort using glide habitat and estimate growth rate throughout the summer. My second chapter focused on determining if there were any seasonal and diel patterns in Diamond Darter detectability during population surveys. In addition to temporal factors, I also assessed five sampling covariates that might influence individual detection. ...

“…Given that floodplains are important for production and recruitment of Bluegill, crappies, and Largemouth Bass compared with main-channel environments and relative to floodplain habitat size (e.g., Hipple Lake covers 0.8% of Lake Sharpe), maintaining river-floodplain connectivity is crucial for effective fisheries management in Lake Sharpe. Connectivity between floodplain habitats and the main channel will likely benefit the centrarchids described above, in addition to species such as Smallmouth Bass and Yellow Perch known to use Missouri River floodplain habitats as juveniles (Kaemingk et al 2007;Carlson et al 2016c). Likewise, loss of river-floodplain connectivity will likely reduce production and recruitment of these species given the importance of floodplains for spawning, rearing, foraging, and refuge.…”

Floodplain habitats often function as spawning, rearing, foraging, and refuge environments for riverine fishes. Although floodplain habitats are important for fish production and recruitment, their natal contributions may vary by species, a topic that has not been thoroughly investigated in large floodplain rivers. We evaluated the natal contributions of floodplain habitats to populations of six socioeconomically important sport fishes in Lake Sharpe, South Dakota, using otolith chemistry. Water samples and age‐0 and adult fishes were sampled from five habitat types (canal, embayment, main channel, stilling basin, tributary). Age‐0 fishes were classified to known natal habitats with 83% mean accuracy based on otolith Ba:Ca and Sr:Ca signatures, with 89% mean accuracy for Bluegill Lepomis macrochirus (89%), crappies Pomoxis spp. (88%), and Largemouth Bass Micropterus salmoides (91%). Floodplain habitats had substantial natal contributions to Bluegill (50%) and crappie (35%) populations. Despite spanning only 0.8% of Lake Sharpe by surface area, a specific floodplain habitat (Hipple Lake) contributed 15% of Largemouth Bass to the Lake Sharpe population—19 times greater than expected under a linear contribution–area relationship. Floodplain habitats had smaller natal contributions (0–5%) for reservoir‐oriented species such as Smallmouth Bass M. dolomieu and White Bass Morone chrysops than for centrarchids and Yellow Perch Perca flavescens. Given that floodplain habitats in Lake Sharpe, particularly Hipple Lake, are disproportionately important for sport fish populations relative to their size, maintaining river–floodplain connectivity is crucial for effective fisheries management. Otolith chemistry is a tool for sport fish management in Lake Sharpe as it reveals habitat‐specific natal contributions of diverse species and can be used to prioritize areas for floodplain protection and rehabilitation, harvest regulations, stock enhancement, and other fisheries management activities.

“…For example, Castello et al (2015) documented effects from a flood pulse on multispecies fishery yields in the lower Amazon floodplains that endured for three years. Carlson et al (2016) reported a six-year effect of flood disturbance on fish diversity and community structure in the Missouri River Delta. The timing of shifts in the TSL fish community documented in the current study would be difficult to predict during any given year.…”

Impact of seasonal hydrological variation on tropical fish assemblages: abrupt shift following an extreme flood event

et al. 2020

Pulsing hydrology is a major factor affecting fish communities in tropical river‐floodplain ecosystems. Species responses to flow alteration are however poorly understood and are thus difficult to predict. Here, we investigated temporal changes in fish community structure (taxonomic and functional) in the Tonle Sap Lake, a floodplain ecosystem in Cambodia that supports the world largest inland fisheries and a UNESCO biosphere reserve. Fish catches were monitored daily at five locations around the lake between 2012 and 2015, with 53 species obtained over the course of the field study. Nine fish traits were recorded and used to characterize the functional composition of fish communities. Temporal changes in functional community structure in response to hydrological variation were assessed using multiple co‐inertia analysis (MCOA) and cross‐correlation function (CCF) approaches. Analyses revealed an abrupt shift in functional structure following extreme flood events in 2013 that included a marked decrease in large‐bodied fish at high trophic levels. Also observed were seasonal changes in the relative abundance of life‐history strategies, feeding habits, and accessory respiratory adaptations. Black fish (species that are relatively sedentary with an equilibrium‐type life‐history strategy) dominated during low‐water periods, whereas white fish (migratory species with opportunistic or periodic life‐history strategies) were dominant during high‐water periods. Dynamics of local assemblage structure were fairly synchronous spatially and were independent of the distance between locations. Species responses to the peak flood pulse were estimated to lag 1–2 months. Findings from this study indicate that management of fisheries resources in the Tonle Sap Lake should consider differential responses of species to hydrology as a function of life‐history strategies and other functional traits as well as factors that may influence time lags in population and community changes to extreme flow events.
