“…We tested this hypothesis further by using individual length‐at‐age data from native and introduced populations. We predicted that growth parameters would be larger in riverine habitats because increased flows have been shown to positively increase Flathead Catfish foraging opportunities and to result in increased growth rates (Jones and Nolite ). However, our study supports the findings of Jolley and Irwin () and Rypel (), as we did not observe differences in growth parameters between reservoir and river populations.…”

Quantifying spatial variability in fish growth and identifying large‐scale drivers of growth are fundamental to many conservation and management decisions. Although fish growth studies often focus on a single population, it is becoming increasingly clear that large‐scale studies are likely needed for addressing transboundary management needs. This is particularly true for species with high recreational value and for those with negative ecological consequences when introduced outside of their native range, such as the Flathead Catfish Pylodictis olivaris. This study quantified growth variability of the Flathead Catfish across a large portion of its contemporary range to determine whether growth differences existed between habitat types (i.e., reservoirs and rivers) and between native and introduced populations. Additionally, we investigated whether growth parameters varied as a function of latitude and time since introduction (for introduced populations). Length‐at‐age data from 26 populations across 11 states in the USA were modeled using a Bayesian hierarchical von Bertalanffy growth model. Population‐specific growth trajectories revealed large variation in Flathead Catfish growth and relatively high uncertainty in growth parameters for some populations. Relatively high uncertainty was also evident when comparing populations and when quantifying large‐scale patterns. Growth parameters (Brody growth coefficient [K] and theoretical maximum average length [L∞]) were not different (based on overlapping 90% credible intervals) between habitat types or between native and introduced populations. For populations within the introduced range of Flathead Catfish, latitude was negatively correlated with K. For native populations, we estimated an 85% probability that L∞ estimates were negatively correlated with latitude. Contrary to predictions, time since introduction was not correlated with growth parameters in introduced populations of Flathead Catfish. Results of this study suggest that Flathead Catfish growth patterns are likely shaped more strongly by finer‐scale processes (e.g., exploitation or prey abundances) as opposed to macro‐scale drivers.

“…When temperature was integrated with measures of floodplain inundation, Schramm and Eggleton () found strong positive relationships between flooding and growth of blue catfish and flathead catfish, Pylodictis olivaris , in the lower Mississippi River. In the middle Mississippi River, Jones and Noltie () concluded that growth of flathead catfish was enhanced following flood conditions. Gutreuter et al () found that growth of largemouth bass and bluegill, Lepomis macrochirus , species that typically exploit littoral habitats (i.e., similar to floodplain habitats), increased during a year with a warm‐season flood in the upper Mississippi River.…”

Catostomids are among the most widespread and ecologically important groups of fishes in North America, particularly in large river systems. Despite their importance, little information is available on their population demographics and even less is known about factors influencing their population dynamics. The objectives of this study were to describe annual mortality, recruitment variation, and growth of eight catostomid species, and to evaluate the effects of discharge and temperature on year‐class strength and growth in Iowa rivers. Catostomids were sampled from 3‐km reaches in four nonwadable rivers during June–August 2009. Northern hogsucker, Hypentelium nigricans, golden redhorse, Moxostoma erythrurum, and shorthead redhorse, M. macrolepidotum, typically lived 6–8 years, had very stable recruitment, and had high total annual mortality (i.e., 40–60%). Golden redhorse exhibited the fastest growth of all species. Growth of northern hogsucker and shorthead redhorse was intermediate to the other catostomids. Highfin carpsucker, Carpiodes velifer, quillback, Carpiodes cyprinus, and white sucker, Catostomus commersonii, had high growth rates, low mortality (i.e., 25–30%), and relatively stable recruitment. River carpsucker, Carpiodes carpio, and silver redhorse, M. anisurum, had higher maximum ages (up to age 11), slower growth, lower total annual mortality (20–25%), and higher recruitment variability than the other species. Neither discharge nor temperature was strongly related to recruitment of catostomids. In contrast, several interesting patterns were observed with regard to growth. Species (e.g., carpsuckers, Carpiodes spp.) that typically consume prey items most common in fine substrates (e.g., chironomids) had higher growth rates in reaches dominated by sand and silt substrate. Species (e.g., northern hogsucker) that consume prey associated with large substrates (e.g., plecopterans) had much faster growth in reaches with a high proportion of rocky substrates. Temperature was weakly related to growth of catostomids; however, discharge explained a substantial amount of the variation in growth of nearly all species. Results of this study provide important information on the autecology of catostomids that can be used for comparison among species and systems. These data also suggest that connection of rivers with their floodplain is an important feature for catostomids in temperate river systems. Published in 2011 by John Wiley & Sons, Ltd.

“…Reduced growth suggests either autochthonous production is limited in the LPR during low‐flow periods or may not be readily used by juvenile channel catfish. Tenets of the flood pulse concept have been deemed important for catfish growth in temperate‐floodplain river systems (Quist & Guy, ; Jones & Noltie, ). However, river production models other than the flood pulse concept may be more appropriate when describing variation in juvenile channel catfish growth within highly braided lowland river systems such as the LPR.…”

“…The river continuum concept suggests that physicochemical processes along the river corridor largely dictate the type of food resource production that can occur at a particular location. The flood pulse concept (Junk et al ., ) has been used to describe increased growth of adult fishes following inundation of floodplain habitats in multiple temperate‐floodplain river systems (Gutreuter et al ., ; Jones & Noltie, ). The Riverine Productivity Model and Riverine Ecosystem Synthesis suggest that the patchily distributed habitats along the river continuum may influence fish growth differently depending on environmental context, including river geomorphology and climate (Thorp & Delong, ; Thorp, Thoms & Delong, ).…”

Summary Characteristics of river hydrology, including components of the natural flow regime, have been used to describe fish growth patterns. Contradictory growth responses among species, life‐stages within species and river systems suggest that eco‐hydrological relationships may not be scalable to all species and river systems; thus, increased knowledge regarding growth–flow relationships among a greater diversity of taxa and river systems may aid conservation and management of riverine fishes. We used channel catfish (Ictalurus punctatus: Ictaluridae), and a set of candidate mixed‐effect linear models to assess juvenile fish growth in relation to components of the flow regime within the Lower Platte River (LPR), Nebraska, U.S.A. The LPR is subjected to extremes in river flow conditions from both natural and anthropogenic sources, and provides a model system with which to assess growth–flow relationships. Juvenile channel catfish growth was influenced by the duration, magnitude and timing of in‐channel flows. Specifically, sustained high‐flow periods during the spring increased growth; whereas, reduced growth occurred during prolonged periods of low‐flow conditions within the LPR. Differences in juvenile channel catfish growth with respect to changing flow conditions may be due to changes in river productivity between low‐ and high‐flow conditions; thus, we discuss the applicability of alternative river production models with respect to juvenile fish growth in wide braided river systems such as the LPR. Reduced duration and changes to the timing of high‐flow periods may result in a myriad of deleterious effects including as our study shows, exacerbating slow growth of juvenile channel catfish and potentially other fishes with similar flow requirements. Conservation and management of large‐river species may benefit from water management policies that consider the complex and often contrasting growth responses of lotic fishes as well as the importance of using multiple aspects of the flow regime when assessing ecological responses.
