“…Duplicate 20‐mL water samples for strontium and calcium concentrations (for calculation of Sr : Ca ratios) and stable oxygen isotopic composition were collected from each site (Figure ) during June–October 2013 and 2014 to verify persistence of differences in stable isotopic and elemental signatures among the Mississippi River and its tributaries that were present during 2006–2012 (Zeigler and Whitledge, , ; Smith and Whitledge, ; Myers et al, ; Phelps et al, ; Norman and Whitledge, ). Water samples for stable oxygen isotope analysis were collected in scintillation vials and sealed with Parafilm® (Bemis Company, Inc., Neenah, WI, USA) to restrict evaporative loss and fractionation (Kendall and Caldwell, ).…”

“…Microchemical and stable isotopic analyses of fish otoliths are powerful techniques for addressing questions regarding environmental history of fishes in numerous freshwater environments, including the Mississippi River and tributaries (Zeigler and Whitledge, ; Phelps et al, ; Norman and Whitledge, ). Trace element and stable isotopic compositions of otoliths reflect those of environments occupied by a fish (Kennedy et al, ; Wells et al, ), are unaltered metabolically following deposition (Campana and Thorrold, ), and serve as natural markers of environmental history of individuals.…”

Insight into environments that contribute recruits to adult fish stocks in riverine systems is vital for effective population management and conservation. Catfish are an important recreational species in the Mississippi River and are commercially harvested. However, contributions of main channel and tributary habitats to catfish recruitment in large rivers are unknown. Stable isotope and trace elemental signatures in otoliths are useful for determining environmental history of fishes in a variety of aquatic systems, including the Mississippi River. The objectives of this study were to identify the principal natal environments of channel catfish Ictalurus punctatus and blue catfish I. furcatus in the middle Mississippi River (MMR) using otolith stable oxygen isotopic composition (δ 18 O) and strontium:calcium ratios (Sr:Ca). Catfishes were sampled during July-October 2013-2014 and lapilli otoliths were analyzed for δ 18 O and Sr:Ca. Water samples from the MMR and tributaries were collected seasonally from 2006-2014 to characterize sitespecific signatures. Persistent differences in water δ 18 O and Sr:Ca among the MMR and tributaries (including the upper Mississippi, Illinois, and Missouri rivers as well as smaller tributaries) were evident, enabling identification of natal environment for individual fish. Blue and channel catfish stocks in the MMR primarily recruited from the large rivers (Missouri and Mississippi) in our study area, with minimal contributions from smaller tributaries. Recruitment and year class strength investigations and efforts to enhance spawning and nursery habitats should be focused in the large rivers with less emphasis in smaller tributaries.

“…Inferred timing of urban pond Bighead Carp introduction lends additional support to the aquaculture origin hypothesis. Based on previously published data relating lapillus radius to TL of Bighead Carp <150 mm (Norman and Whitledge ), abrupt drops in Sr:Ca within 150 μm of the otolith primordium for most of the urban pond Bighead Carp suggests these fish may have been transferred into ponds at a relatively small size (≤100 mm TL) likely during age 0 or age 1 rather than at older ages. These results indicate that captured Bighead Carp spent their early life in water(s) with higher Sr:Ca and the remainder of their lives as residents of water(s) with Sr:Ca consistent with that of the urban ponds.…”

“…Otolith δ 18 O is strongly correlated to δ 18 O of ambient water (Dufour et al. ; Ashford and Jones ; Norman and Whitledge ). Thus, large‐scale geographic differences in precipitation δ 18 O and corresponding differences in surface water δ 18 O between the south‐central USA (where aquaculture facilities with Bighead Carp existed) and the north‐central USA (Kendall and Coplen ) were likely responsible for the observed differences in otolith δ 18 O of Illinois River Bighead Carp and Silver Carp compared with aquaculture‐reared Bighead Carp.…”

Planktivorous Bighead Carp Hypophthalmichthys nobilis and Silver Carp H. molitrix are two invasive species that pose a severe threat to native aquatic biota. Efforts have been made to inhibit Bighead Carp and Silver Carp expansion into the Great Lakes through hydrologically connected systems, but understanding their expansion to and from hydrologically disconnected systems could further reduce this risk. We assessed the origin of 23 Bighead Carp and 1 Silver Carp captured from Chicago Urban Fishing Program ponds using otolith chemistry. Otolith core δ18O and δ13C of captured Bighead Carp did not overlap with ranges of otolith δ18O and δ13C from Bighead Carp and Silver Carp from the Illinois River but was consistent with otolith δ18O and δ13C of Bighead Carp obtained from aquaculture facilities. Likewise, otolith core Sr:Ca of 19 captured Bighead Carp was higher than the range of otolith Sr:Ca from Illinois River Bighead Carp and Silver Carp. Due to inferred timing of introduction (likely age‐0 or age‐1 fish), these Bighead Carp may have been released incidentally via stocking sport fish shipments contaminated with the carp. Contrastingly, otolith chemistry results suggest that the captured Silver Carp originated from the Illinois River, although timing of introduction of this fish could not be inferred. Overall, our results indicate that nearly all fish analyzed did not originate from rivers within the Mississippi River basin and were instead likely introduced through stocking contaminated shipments of fish. Even though Chicago Urban Fishing Program ponds now pose a minimal threat for Bighead Carp and Silver Carp expansion into Lake Michigan, sustained urban pond monitoring and nonnative fish removal may limit or eliminate this alternative invasion pathway. Additionally, continued vigilance in understanding the origin of stocked fish and culture environment (e.g., polyculture) could decrease the likelihood of future invasive species introductions through contaminated sport fish stockings.

The Common Carp Cyprinus carpio is an invasive fish whose populations have grown to ecologically damaging levels in the North American Midwest. It has been shown that some shallow nursery habitats contribute disproportionally to population growth of Common Carp in interconnected Midwestern lake systems. The ability of managers to discriminate which shallow basins are producing Common Carp across these systems could increase the efficacy of management practices aimed at disrupting recruitment. We tested whether adult and juvenile Common Carp collected across an interconnected Midwestern lake system could be distinguished based on the concentrations of 11 trace elements measured in their otoliths using laser ablation and high-resolution inductively coupled plasma mass spectrometry (n = 157). Elemental concentrations in water were also measured with inductively coupled plasma mass spectrometry and found to differ among sites and between habitats, indicating that variation in otolith microchemistry was likely. Aluminum, barium, copper, iron, potassium, lithium, magnesium, sodium, phosphorus, and strontium in the edge region of otoliths differed significantly among Common Carp from all capture sites. Barium, iron, lithium, manganese, and phosphorus differed significantly among juvenile Common Carp from three nursery basins. Aluminum, barium, copper, iron, potassium, lithium, sodium, phosphorus, and strontium were significantly different between nursery and nonnursery habitats. We then investigated the ability to use these elemental otolith edge signatures to differentiate capture locations and distinguish between locations that are active and putative nursery habitats. Quadratic discriminant analysis could classify otoliths to collection site with an accuracy of 54%. Quadratic discriminant analysis had increased accuracy when restricted to juvenile Common Carp (76%) and when classifying Common Carp to nursery and nonnursery habitat types (87%). Further analysis of otolith and water microchemistry indicates temporal instability and suggests a need to collect a multiyear library of otoliths prior to utilization by managers.
