“…The different water sources used are consistent from year to year (state fish hatchery managers, personal communication) and have been shown to be (1) significantly different elementally and (2) temporally stable (Boehler et al. ). Otolith chemistry is a popular and effective method for discriminating among stocks of fish (Campana ; Elsdon et al.…”

“…Most notably, it has been demonstrated that the otolith chemistry signatures of steelhead reared at different hatcheries around Lake Erie are significantly different and temporally stable, allowing stocks of steelhead from different year‐classes to be accurately discriminated (Boehler et al. ).…”

“…Studies that have focused on the prevalence of salmonid strays at different upstream locations have been contradictory, as a slightly higher proportion of strays was found at upstream locations in a Lake Erie tributary in Pennsylvania (Boehler et al. ), whereas the proportions of hatchery Pink Salmon Oncorhynchus gorbuscha strays from individual hatcheries in Prince William Sound, Alaska, declined exponentially with upstream distance from a given release site (Brenner et al. ).…”

Application of Otolith Chemistry to Investigate the Origin and State‐Straying of Steelhead in Lake Erie Tributaries

In Lake Erie, the fishery for steelhead Oncorhynchus mykiss is overwhelmingly dominated by stocking from state agencies in Michigan, New York, Pennsylvania, and Ohio. Managers that stock steelhead may become concerned if a sizeable portion of the fish they stock do not return to the waters in which they were released and instead stray to other states (“state‐straying”). During fall 2009, spring 2010, and spring and fall 2015, we evaluated the origin and state‐straying of adult steelhead in five annually stocked tributaries of Lake Erie. We also investigated spatial differences in the origin and state‐straying of adult steelhead at different stream locations in two tributaries during 2015. Otolith chemistry signatures were first used to discriminate among yearling steelhead from each of the state hatcheries that stock Lake Erie and wild juveniles from Cattaraugus Creek, New York, and the Grand River, Ontario, resulting in a mean jackknifed classification accuracy of 88% (range = 72–100%). Otolith chemistry analysis was then performed on unknown‐origin adult steelhead collected in Lake Erie tributaries during the fall and spring spawning runs, and natal sources were identified by using source‐specific otolith chemical signatures. State‐strays averaged 46% (range = 13–88%) of the adult fish collected, and high percentages of strays were identified in Chautauqua Creek, New York (72%), and Cattaraugus Creek (88%). Steelhead collections in these New York tributaries during a second year revealed that the percentage of strays present was consistently high, and large proportions of strays were identified in both upstream and downstream locations. These results suggest that state‐straying is widespread in Lake Erie tributaries and that strays make up a large proportion of New York's Lake Erie tributary fishery. Strategies to reduce straying may include practicing upstream releases and reducing the number of hatchery fish that are released in some states.

“…Although much of the research is focused on marine and estuarine environments, otolith chemistry is being increasingly utilised for a diverse range of applications in freshwater systems. Such applications include the identification of recruitment and natal sources (Crook & Gillanders 2006, Pangle et al 2010, invasive species' origins (Munro et al 2005, Wolff et al 2012 and habitat use (Brazner et al 2004); the discrimination of wild and hatchery-reared stocks (Bickford & Hannigan 2005, Coghl an et al 2007) and diadromous and non-diadromous ecotypes (Godbout et al 2010); and the determination of release-site fidelity (Boehler et al 2012) and riverine infrastructure impacts (Clarke et al 2007). Environmental interpretations based on otolith elemental composition rely on the underlying assumption that fish derive elements predominantly from the water, either via the gills in freshwater fish or via the intestine in marine fish (Campana 1999), and that there is a predictable and consistent relationship between the chemistry of the otolith and the chemistry of the water.…”

Rainbow Trout Oncorhynchus mykiss were monitored over two consecutive vernal migration periods at a nature‐like fishway on the Beaver River, Ontario, to assess attraction efficiency, passage efficiency, multiple fish passage metrics, and interannual return rates from Georgian Bay, Lake Huron. Fishway evaluations have shifted to fill knowledge gaps related to the passage of nonsalmonids; however, surprisingly little work has been conducted with Rainbow Trout, with no known study assessing attraction or passage at a nature‐like fishway. Attraction efficiency was 53% and passage efficiency was 100% in 2017; only two of the radio‐tagged fish returned to the fishway in 2018. Upstream passage through the fishway required an average time of 152 ± 122 min. Fish spent 19–43 d upstream before returning to Lake Huron, where downstream passage required as little as 15 min. Overall, there were no significant relationships between any of the fish passage metrics and fish size or condition. These results can be used as a foundation for anadromous O. mykiss subspecies passage research and suggest that fisheries managers may need to adjust annual fishway counts. Future research should focus on developing methods to directly integrate temporal passage metrics into estimates of fishway efficiency.
