Abstract Seasonal and life stage variation in microhabitat use is an important driver of fish survival bioenergetics, but knowledge selection during colder periods generally lacking warmwater streams. Our objective was to examine changes by age‐0 (TL ≤ 85 mm) age‐1+ > Smallmouth Bass Micropterus dolomieu from autumn winter streams the southwest Ozark Highlands ecoregion. We examined (depth, velocity, substrate, cover, temperature) 2017 (Spavinaw Creek) 2018 Spring creeks). During winter,...
Larval fish ecology is poorly characterized because sampling difficult and tools for phenotypically identifying larvae are developed. While DNA barcoding can help address the latter problem, ‘universal’ primers do not work all species. The Roanoke River in southeastern United States includes seven darters (Family Percide: Tribe Etheostomatini). We made 393 collections of larval fishes 2015 2018, examined darter morphometric pigmentation traits, developed PCR amplifying DNA, evaluated three...
Abstract Stocking of Rainbow Trout Oncorhynchus mykiss commonly provides seasonal or mitigation fisheries; however, these fish are usually small and ecosystem effects spatially temporally limited. Yet agencies receive requests to stock in relatively natural settings (i.e., not tailwater fisheries), where introductions may have greater consequences. The size introduced is an important factor determining biotic interactions with native species; therefore, our objectives were assess the feeding...
Abstract Stocking Rainbow Trout Oncorhynchus mykiss to create additional angling opportunities is common; however, the spatial and temporal dynamics of such stocking practices are unclear in groundwater‐influenced, warmwater streams. Our objectives were determine dispersal from a location on Spavinaw Creek, Oklahoma quantify apparent survival two cohorts stocked November 2018 February 2019. PIT‐tagged prior autumn ( N = 495) winter 605) located poststocking using both an active floating...
Abstract Objective We sought to evaluate accurate and reproducible detection of Myxobolus cerebralis (Mc), the causative agent whirling disease, by using nested polymerase chain reaction (nPCR) three previously established real-time quantitative PCR (qPCR) assays: K18S (Kelley 18S), C18S (Cavender Hsp70 (heat shock protein 70). used a “fit for purpose” approach combined with intra- interlaboratory testing identify molecular method that would be equivalent currently accepted nPCR procedure...
Two catostomid fishes, Carpiodes cyprinus (Quillback) and Moxostoma collapsum (Notchlip Redhorse), were recently discovered in the New River watershed (Ohio basin) Virginia. The fish fauna is naturally depauperate relative to surrounding watersheds, it has been altered substantially due non-indigenous species introductions. Notchlip Redhorse Quillback are established Claytor Lake dispersing into novel reaches of mainstem River. We suspect that these became following bait-bucket introductions...
Abstract Objective Juvenile tiger muskellunge (Northern Pike Esox lucius × Muskellunge E. masquinongy ) are cannibalistic, which can lead to a substantial reduction in yields within an intensive culture environment. Utah hatcheries have traditionally raised the female Northern male cross, and hatchery managers reluctant raise due perceived difference (increase) cannibalism rates when rearing this cross. Methods We both crosses replicated microcosms evaluate differential between them. All...

Abstract We used bomb calorimetry to quantify the energy density of three Prosopium fish species endemic Bear Lake, Utah–Idaho, that we collected in 2020–2021: Lake Whitefish abyssicola, Bonneville spilonotus, and Cisco gemmifer. found mean ± standard deviation wet weight densities were 6,312 760 J/g for Whitefish; 5,301 778 4,743 443 Cisco. built linear mixed models relationships between dry matter ratio (i.e., dried a fish) all species, suggesting future samples could potentially be...
