“…Model likelihood was ranked using the deviance information criterion (DIC), with the lowest DIC value selected as the top model (Spiegelhalter et al 2002; Albert 2009). This approach was selected because it has been used previously for model selection when multiple Bayesian mark–recapture models have been fit (Stewart et al 2017; Haxton and Friday 2018). Parameter estimates were then summarized using the mean ± SD for the top T‐bar anchor tag and PIT tag models.…”

Population parameter estimates from mark-recapture studies are dependent on individuals retaining marks or tags. Therefore, tag retention estimates are needed for different tag types and anatomical tagging locations. Few studies have empirically quantified the bias from tag retention on fish population parameters that are derived from mark-recapture studies. We examined differences in retention between T-bar anchor tags and PIT tags as well as among four anatomical locations for PIT tags in Brown Trout Salmo trutta in a tailwater fishery in Arkansas, USA. We also estimated the relative bias of tag type and PIT tag location on apparent survival estimates from Cormack-Jolly--Seber models. Tag retention for the anchor tags was 15.1% lower than that for the PIT tags after 1 year and 46.1% lower after 4 years. Greater PIT tag retention resulted in less biased estimates of apparent survival for PIT tags (average −7.1%) than for anchor tags (average −37.8%). However, PIT tags that were placed in different anatomical locations had varying retention rates, so the degree of relative bias that was associated with their apparent survival estimates also varied. Inserting the PIT tags in the cheek or dorsal musculature provided the greatest retention for Brown Trout and may provide the least biased apparent survival estimates from future mark-recapture studies.

“…conditions, and more intensive surveys would be necessary to further explore this hypothesis. Little information exists regarding the role that hydrology plays in Yaqui Catfish biology (Stewart et al 2017), such as for spawning or feeding functions, but closely related Channel Catfish are known for migratory movements of up to 400 km for feeding and spawning, which are related to precipitation, temperature, and hydrology regimes (Hubert 1999). Similarly, our finding that Yaqui Catfish occurrences were in greater proportion than expected in urban and cropland land cover was novel and could be explained by water availability.…”

“…We identified some evidence for Yaqui Catfish refugia (areas of long-term persistence) based on spatial proximity of occurrence records with disparate collection dates, indicating that suitable habitats exist in a small area near the U.S. border (Cajon Bonito). Cajon Bonito has long been known as one of the last remaining population strongholds for Yaqui Catfish (and other Yaqui River basin native fishes) and was once used as an important source of mature individuals for founding the captive stock that once supported the now-extinct population in the United States (Varela-Romero et al 2011;Stewart et al 2017). However, even at Cajon Bonito, Channel Catfish and their hybrids with Yaqui Catfish have been observed (Hafen 2020;A.…”

The Yaqui Catfish Ictalurus pricei is an understudied species, with limited information available on its ecology, distribution, and local habitat use. Native to the southwestern United States and northwestern Mexico, Yaqui Catfish populations are declining, which has prompted listing of the species as threatened in the United States and as a species of concern in Mexico. Water overallocation, habitat degradation, invasive species introductions, and hybridization with nonnative Channel Catfish I. punctatus have caused the populations in Mexico to decline. The United States population collapsed after years of low recruitment. To better focus conservation efforts as well as define habitat associated with Yaqui Catfish occurrences, we assessed the distribution in the Yaqui River basin of Mexico by using historical data at a landscape scale. Yaqui Catfish were historically found across the watershed among a diversity of environments but were most frequently associated with small, intermittent streams. Basin land cover was dominated by forest, shrubland, and grassland, and Yaqui Catfish generally occurred in stream segments at similar proportions. However, a small number of Yaqui Catfish occurrences were associated with urban and cropland land cover types in proportions greater than the availability of those categories on the landscape. With the species facing declines in the region, this work will help to inform future conservation efforts aimed at securing the Yaqui Catfish, protecting suitable habitat, and better defining its current status in Mexico.

“…elsewhere. For example, Yaqui catfish Ictalurus pricei (Rutter, 1896) is on a trajectory towards extinction in the United States because of declining spring flows, reduced surface waters, competition with non‐native species, and loss of genetic integrity due to hybridization and introgression with introduced species (Stewart et al., 2017). Similar detrimental effects of human alterations to riverscapes on native freshwater fish species distributions are documented on a global scale using methods similar to our approach, including fishes in the families Salmonidae (McKelvey et al., 2016), Centrarchidae (Alvarez et al., 2015; Koppelman & Garrett, 2002; Taylor et al., 2018), and Cyprinidae (Pyke, 2008; Wilde & Echelle, 1992).…”

Aim To review the conservation status of Headwater catfish Ictalurus lupus (Girard,1859) in the United States, including quantifying environmental correlates with range contraction and hybridization and introgression with Channel catfish Ictalurus punctatus (Rafinesque, 1818) to inform conservation prioritization. Location Texas and New Mexico, USA. Methods We used random forest models to construct species distribution models (SDMs) based on historical (1980–1999) and contemporary (2000–2019) data and 13 classes of remotely sensed stream network data. We measured hybridization and introgression with the widely introduced Channel catfish using external morphology, mitochondrial DNA (mtDNA), and a nuclear gene (RAG2). Results Species distribution models illustrated temporal reduction in suitability for Headwater catfish among the species’ namesake headwater streams, including streams with steeper slopes, faster velocities, and higher elevations. Modelling also revealed reduced suitability of larger streams greater distances from groundwater springs, the same streams frequently occupied by non‐native Channel catfish. A general pattern of increased use of streams draining watersheds with altered or developed land uses was apparent. Assessment of introgression and hybridization with non‐native channel catfish at nine locations showed evidence of ongoing or past hybridization at six locations. Persistence of potentially non‐introgressed populations were found at three locations with smaller sample sizes. Main conclusions Modelling temporal changes in Headwater catfish distribution provided critical insight into the types and locations of streams that should be targeted for habitat preservation or restoration. Conservation and management of Headwater catfish will require priority decisions based on existing levels of introgression and the practicality of preventing further contact with Channel catfish. Maintaining Headwater catfish populations in springs that are also heavily used by humans will be critical for conservation of the species in the United States.
