    The Sport Fish Restoration Program as a Funding Source to Manage and Monitor Bowfishing and Monitor Inland Commercial Fisheries

    Abstract: The Sport Fish Restoration Program (SFR) has been a stable and highly successful funding program supporting state fisheries research, propagation, and management activities since its inception in 1950. The expanding sport of bowfishing in the past 2 decades, and research over a comparable time period showing very long lifespans of underappreciated native fish species, opens the door to some new ways to classify, manage, and fund monitoring of these natives under the SFR program, while encouraging sport and commercial take of invasives. Evidence from bowfishing and from changes in angling patterns for some nongame species indicates that the time has come to consider reclassifying underappreciated native species into some form of sport status (entirely separate from non‐native invasives) and thereby potentially expanding the scope of species projects financed with SFR funds. Reclassification will also function to upgrade the status of underappreciated native species taken within agencies, with bowfishers and anglers, and with the public. It then opens the door to improved, and necessary, monitoring of inland commercial fisheries (often targeting the same species), an activity which has needed improvement and a reliable funding source for decades. We suggest that our approach is a comparatively straightforward one that is scientifically defensible and implementable within the existing state–federal management jurisdictions and institutions.

    Abstract: The endangered Pallid Sturgeon, Scaphirhynchus albus, has been actively managed to prevent population declines, including stocking of hatchery-raised fish. The gut microbiome plays an innate role in an organism’s absorption of nutrients by increasing nutrient availability and can provide new insights for Pallid Sturgeon management. In this study, the Pallid Sturgeon’s microbiome is dominated by the phyla Proteobacteria, Firmicutes, Actinobacteria and Fusobacteria. It was also determined that the gut bacterial diversity in hatchery-raised Pallid Sturgeon was not significantly different from wild Pallid Sturgeon, supporting that hatchery-raised Pallid Sturgeon are transitioning effectively to wild diets. There is also a high degree of intraspecific variation in the bacterial and eukaryotic sequences amongst individual Pallid Sturgeon microbiomes, suggesting the Pallid Sturgeon may be omnivorous. This study demonstrated that genetic markers may be used to effectively describe the dietary requirements for wild Pallid Sturgeon and provides the first genetic evidence that Pallid Sturgeons are effectively transitioning from hatchery-raised environments to the wild.

    Assessment of Hatchery‐Reared Pallid Sturgeon Survival in the Lower Missouri River
    Wiley ; 2010
    In:  North American Journal of Fisheries Management Vol. 30, No. 3 ( 2010-06), p. 671-678

    Abstract: The population of pallid sturgeon Scaphirhynchus albus in the lower Missouri River between Gavins Point Dam (river kilometer [rkm] 1,305.2) and the confluence with the Mississippi River (rkm 0.0) remains imperiled, little to no natural recruitment occurring. Artificial propagation and subsequent population augmentation (i.e., stocking) may be the only viable option for maintaining pallid sturgeon populations in the lower Missouri River in the near term. Because relatively little is known about the ability of hatchery‐reared pallid sturgeon to survive, the objective of this study was to quantify survival estimates for hatchery‐reared pallid sturgeon stocked into the lower Missouri River. We used stock–recapture data collected from 1994 to 2008 to derive survival estimates based on the Cormack–Jolly–Seber model within program MARK. Since 1994, a total of 78,244 hatchery‐reared pallid sturgeon have been released and 1% of these have been recaptured. Recapture numbers by size at stocking were as follows: 48 age 0, 730 age 1, and 38 older than age 1. Stocked age‐0 hatchery‐reared pallid sturgeon had an estimated apparent survival rate of 0.051 (SE = 0.008), compared with 0.686 (SE = 0.117) for age‐1 fish and 0.922 (SE = 0.015) for fish older than age 1. Our analysis confirms that hatchery‐reared pallid sturgeon can survive in the wild and contribute to the overall population of this species. These estimates should provide critical information for decisions regarding stocking strategies within the lower Missouri River and enable biologists to estimate the number of stocked pallid sturgeon that reach sexual maturity.

    Conditional Capture Probability of Pallid Sturgeon in Benthic Trawls

    Abstract: Long‐term population monitoring assumes that relative abundance reflects trends in the population. Sampling efficiency and capture probability are assumed to be consistent so samples can be temporally and spatially compared. Benthic otter trawls are being used for a long‐term monitoring project on the Missouri River. To estimate the capture probability of Pallid Sturgeon Scaphirhynchus albus , we used acoustic telemetry to locate and target tagged sturgeon with benthic otter trawls. Conditional capture probability ( p i *) of a fish in a known location was only 0.08 on the first pass, increased slightly ( p i * = 0.18) on the second pass, and again on the third pass ( p i * = 0.26). Individual habitat parameters or their interactions did not explain when Pallid Sturgeon were successfully or unsuccessfully captured. Our study suggests that otter trawls are a highly inefficient gear for capturing Scaphirhynchus species. Therefore, relative abundance indices based on otter trawl captures need to be assessed cautiously for juvenile and adult Pallid Sturgeon, especially in highly variable conditions.

    Using mark–recapture information to validate and assess age and growth of long-lived fish species

    Abstract: Long-lived species from marine and freshwater environments have experienced declines linked to anthropogenic effects such as overexploitation, dam construction, and habitat modification. An understanding of the age structure and the associated dynamics determined from these data for long-lived species is critical for both perseverance of at-risk species and maintenance of exploited species. We used pallid sturgeon (Scaphirhynchus albus) to evaluate the efficacy of mark–recapture data from known-age, hatchery-reared fish (ages 1 to 7) to corroborate age and growth estimates obtained from sectioned pectoral fin rays. Accuracy of age estimates from known-age fish was 13%, whereas 72% of estimates were within 2 years of the true age. Annual growth was significantly different between estimated growth (back-calculated) and actual observations of tagged pallid sturgeon. Age for pallid sturgeon of any given size was estimated with parameters derived from mark–recapture data, and the predicted length-at-age relation was similar to observations from known individuals. In instances where age determination for all ages of interest cannot be verified, mark–recapture appears to be a viable solution for examining growth and has shown promise as a tool for estimating ages in long-lived species with calcified structures that are difficult to read.

    Evidence of Limited Recruitment of Pallid Sturgeon in the Lower Missouri River
    U.S. Fish and Wildlife Service ; 2019

    Abstract: Pallid Sturgeon Scaphirhynchus albus are endemic to the Missouri and Mississippi river basins and are rare throughout their range. The species was listed as federally endangered with little to no evidence of natural recruitment. Since population augmentation was initiated as a recovery objective in the early 1990s, thousands of hatchery-origin Pallid Sturgeon have been stocked in the lower Missouri River (Gavins Point Dam [river kilometer 1,305.1] to the confluence of the Mississippi River [river kilometer 0.0] ). Efforts to discriminate natural reproduction and recruitment of wild-origin Pallid Sturgeon from hatchery-origin fish has been hampered by tag loss in hatchery-origin sturgeon, inconsistent documentation of hatchery parental crosses, and the failure to collect tissue samples for genotyping all broodstock. However, the recent reconstruction of missing parental genotypes from known hatchery-origin progeny and from cryopreserved milt made it possible to examine Pallid Sturgeon recruitment. Therefore, our objectives were to 1) determine the likelihood that unmarked Pallid Sturgeon captured from the lower Missouri River were the result of natural recruitment and 2) examine the length distribution of wild- and hatchery-origin fish to determine if a difference exists by origin and examine the life-stage distribution. Genetic analysis showed that from 2003 to 2015, 358 “presumptive wild-origin” Pallid Sturgeon were captured in the lower Missouri River and the comparison between the length distributions of wild- and hatchery-origin fish did not provide any additional clarification into potential wild-origin fish. Low recruitment may be due to a small breeding population, high mortality of early life stages, hybridization with Shovelnose Sturgeon Scaphirhynchus platorynchus, or transport of drifting free embryos or larvae into inhospitable habitats. Determining what factors are limiting recruitment is the important next step for the recovery of Pallid Sturgeon in the lower Missouri River.

    Range-wide age and growth characteristics of shovelnose sturgeon from mark–recapture data: implications for conservation and management
    Canadian Science Publishing ; 2015

    Abstract: We used mark–recapture data from shovelnose sturgeon (Scaphirhynchus platorynchus) to describe range-wide growth characteristics and developed a model to estimate ages. Data were solicited throughout much of the current distribution of shovelnose sturgeon, specifically from the mainstem Missouri and Mississippi rivers and their tributaries. Shovelnose sturgeon exhibited variable growth among locations; however, adult fish exhibited almost no growth after they reached a particular size, presumably the size at sexual maturity. Shovelnose sturgeon from the Mississippi River basin attained greater maximum sizes and ages compared with the Missouri River basin. However, two populations from the Mississippi River that received high exploitation from commercial harvest had truncated age distributions with smaller asymptotic lengths. Lower Missouri River populations were characteristic of exploited populations (i.e., smaller fish and reduced longevity), presumably a result of anthropogenic effects. Wide discrepancies in maximum age and size suggest shovelnose sturgeon are capable of displaying phenotypic plasticity in response to exploitation or environmental influences. Determining metapopulation dynamics is a priority because it is unknown how population connectivity may influence dynamic rate functions and persistence of large-river fishes. Identifying potential source–sink connections in terms of population dynamics may provide a template for direction of future restoration and recovery efforts.
