“…Results from this study have implications for understanding the ecology of, and ultimately managing, gizzard shad and walleye populations. Previous gizzard shad environmental history studies in South Dakota have focused on life history factors (e.g., larval hatch timing, growth, density, survival, reproduction, and recruitment) as related to summer–winter water temperatures, zooplankton abundance, and density of Age 0 fish (Fincel, Chipps, Graeb, & Edwards, ). Our study adds to this knowledge base and informs gizzard shad management by providing quantitative evidence indicating the importance of floodplain habitats, particularly Hipple Lake, for gizzard shad spawning and recruitment.…”

Reduced river–floodplain connectivity can decrease fisheries production and cause ecological and socioeconomic consequences. In 2011, the largest flood on record in the Missouri River since 1898 nearly eliminated connectivity between an embayment (Hipple Lake) and Lake Sharpe, impeding movement of walleye (Sander vitreus) and a forage fish, gizzard shad (Dorosoma cepedianum). Thus, we used otolith chemistry to quantify Hipple Lake's natal contribution to Lake Sharpe's gizzard shad population and forecast effects of connectivity loss on the reservoir's socioeconomically important walleye fishery. Fish were classified to natal habitats with 79–89% accuracy, with most gizzard shad (64%) hatching in floodplain habitats (i.e., embayments, tributaries, canals, and stilling basins). Hipple Lake contributed 12% of gizzard shad to Lake Sharpe, more than a tributary (4%) and embayment (0%) but less than a canal (27%) and stilling basin (21%). Hipple Lake (178 acres) covers 0.31% of Lake Sharpe (56,884 acres), so its natal contribution is 38 times what would be expected if contribution was linearly related to area. Sediment and water management to maintain connectivity between Lake Sharpe and Hipple Lake and other floodplain habitats is important for continued gizzard shad production and prey supply for the walleye fishery. Otolith chemistry facilitates assessment of gizzard shad natal contributions in different habitats, serving as a fisheries management tool to inform floodplain habitat protection and rehabilitation after floods.

“…We had hypothesized that Smallmouth Bass would be a prominent predator of the juvenile Chinook Salmon and that overall predation would be higher in Spring Creek, as the relative abundances of all predators are higher in Spring Creek compared to Whitlock Bay (Fincel et al. 2014). Our results supported the hypothesis of high losses of Chinook Salmon to Smallmouth Bass, as the majority (70%) of predation occurred during the daytime, which aligns with the typical daytime feeding habits of Smallmouth Bass (Vigg et al.…”

“…Our results did identify a difference in predation rates between study sites, which might be explained by differences in the relative abundance of predators (Michel et al 2018), the timing of stocking (Vollset et al 2017), and abiotic factors that influence predator feeding rates and efficiencies. We had hypothesized that Smallmouth Bass would be a prominent predator of the juvenile Chinook Salmon and that overall predation would be higher in Spring Creek, as the relative abundances of all predators are higher in Spring Creek compared to Whitlock Bay (Fincel et al 2014). Our results supported the hypothesis of high losses of Chinook Salmon to Smallmouth Bass, as the majority (70%) of predation occurred during the daytime, which aligns with the typical daytime feeding habits of Smallmouth Bass (Vigg et al 1991;Johnson and Dropkin 1995) compared to the nocturnal feeding habits of Walleye (Schlick 1978;Wuellner et al 2011).…”

ObjectiveAcoustic telemetry is a tool commonly used to better understand the fates of fish following a stocking event. Until recently, predation on stocked fish could only be inferred by observing and identifying abrupt changes in tag detection histories. Recently, a novel predation transmitter has provided better insight into how predation affects poststocking survival. The main objective of this study was to use these transmitters to estimate predation rates on stocked juvenile Chinook Salmon Oncorhynchus tshawytscha in a landlocked system (Lake Oahe, South Dakota). Our secondary objectives were to determine how quickly predation was occurring, the time of day of predation events, and if there were differences in size between predated and nonpredated fish.MethodsIn 2021 and 2022, we surgically implanted Innovasea V5D 180‐kHz transmitters in 110 juvenile Chinook Salmon. These tagged Chinook Salmon were stocked at two locations on Lake Oahe along with a large cohort of untagged individuals. The tagged Chinook Salmon were passively tracked using an array of Innovasea VR2W 180‐kHz acoustic receivers.ResultAcross the two study years, we observed a mean predation rate (±SE) of 32.9 ± 6% on the tagged Chinook Salmon. Predation on the tagged Chinook Salmon occurred relatively quickly, with a mean time to predation of 86.7 ± 10.8 h. Additionally, 70% of the observed predation occurred during the daytime. Interestingly, results indicated that total length did not differ between fish that were preyed upon or and those that were, but there was a difference in total weight between the two groups.ConclusionOur results provide insight into recruitment bottlenecks within this population and offer information to other researchers regarding the advantages and limitations of this novel technology. Understanding how to mitigate predation could help to guide future stocking strategies to ensure a better return on investment for costly stocking programs.

“…Gizzard Shad are a primary forage base for nonnative predators in Lake Oahe (Wuellner et al 2010;Fincel et al 2014Fincel et al , 2016, and we found relationships between age-0 Gizzard Shad and adult predators in all reservoirs. In Lake Oahe, severe winters in 2009-2011 reduced the Gizzard Shad population in Lake Oahe to levels undetectable using methods employed for annual surveys (Fincel et al 2013(Fincel et al , 2017. Overwinter mortality is likely continuing to suppress the Gizzard Shad population in Lake Oahe, and with decreased CPUE, predation is likely keeping Gizzard Shad CPUE low.…”

The Missouri River in South Dakota was dammed in the 1950s and 1960s, altering the biotic and abiotic factors that potentially affect native species in the mainstem reservoirs. Little research has been conducted regarding what factors regulate age-0 CPUE (catch per unit effort) of native fish species since the damming occurred. Thus, we examined age-0 CPUE for thirteen native fish species in the four Missouri River mainstem reservoirs. We analyzed data from 1995-2015 in Lake Oahe, 2002-2016 in Lake Sharpe, 1998-2008 in Lake Francis Case, and 2000-2013 in Lewis and Clark Lake. Not all species were sampled in all reservoirs. We evaluated potential environmental (inflow, gauge height, peak flow, precipitation, air temperature) and biological (CPUE of other native species, non-native CPUE, predator CPUE) factors that have documented impacts on age-0 native fish CPUE. Significant relationships existed between age-0 native fish CPUE and both biotic and abiotic factors in all four reservoirs, but specific factors related to native fish CPUE were species and reservoir dependent. For all species examined in all reservoirs except age-0 Emerald Shiner Notropis atherinoides CPUE in Lewis and Clark Lake, age-0 CPUE was either stable or increasing. Age-0 Emerald Shiner CPUE in Lewis and Clark Lake was most supported by total age-0 non-native CPUE and adult White Bass Morone chrysops CPUE, and a positive relationship existed between age-0 Emerald Shiner CPUE and both factors. We believe our findings provide valuable insight into successful management of native fish populations.
