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.
An adult Silver Carp Hypophthalmichthys molitrix with a focally extensive skin lesion near the caudal peduncle and mild iridial hemorrhage was submitted to the Aquatic Research and Diagnostic Laboratory (ARDL) in Stoneville, Mississippi, as part of a fish kill investigation. Touch impressions of this musculoskeletal lesion revealed small cocci (∼1 μm) in pairs or chains within an inflammatory milieu. A pure Gram-positive cocci isolate was obtained from the brain, while cultures of the kidney and muscle yielded multiple bacterial colony types, including the Gram-positive cocci seen in the brain. This brain isolate was characterized biochemically and identified as Lactococcus spp. Analysis of the near complete 16S small subunit ribosomal DNA (SSU rDNA) and DNA gyrase subunit B (gyrB) gene sequences revealed the bacterium to be L. lactis subsp. lactis (SSU rDNA: 100% identity, 1,372/1,372 bp; gyrB: 99.7% identity, 1,779/1,785 bp). Comparatively, at the gyrB locus the case isolate shared less than 90% similarity to L. lactis subsp. cremoris (1,599/1,781 bp) and less than 80% homology to L. garvieae (1409/1775 bp). Histopathological examination confirmed a severe meningoencephalitis, a moderate mononuclear myositis, and a mild interstitial nephritis. We believe this represents the first report of a natural infection by L. lactis subsp. lactis in Silver Carp.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
