“…Growth rates from introduced fish populations are generally thought to increase rapidly in the early stages of establishment into the new system. After a period of rapid growth, the growth rates plateau as the environmental carrying capacity is reached (Sakai et al 2001;Lucchesi et al 2017). Based on this and previous Flathead Catfish growth studies (Kwak et al 2006;Bonvechio et al 2016), we predicted that more recently introduced populations would have higher K and lower L ∞ estimates.…”

Spatial Variability and Macro‐Scale Drivers of Growth for Native and Introduced Flathead Catfish 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.

Flathead Catfish Pylodictis olivaris have been either intentionally or accidentally introduced into Atlantic Slope drainages extending from Florida to Pennsylvania and have quickly become established. In Pennsylvania, Flathead Catfish were first detected in the Schuylkill River at the Fairmont Dam in 1999 and in the Susquehanna River at Safe Harbor Dam in 2002. The species has since moved throughout the respective basins, with subsequent detections during 244 riverine surveys in these drainages. Fishway and electrofishing surveys in the tidal Schuylkill River, a Delaware River tributary, have documented an increase in abundances since 2004, when the surveys were first implemented. Hoop‐net surveys in nontidal large‐river reaches found mean (±SD) catch rates varying from 0.00 to 4.51 ± 4.38 fish/series. A Bayesian hierarchical Poisson regression model indicated that Flathead Catfish abundance decreased as the distance from the initial point of detection increased, demonstrating a general pattern of fish expansion upstream from the point of detection. The distance downstream of the nearest dam, although not significant, had a relatively high posterior probability of being negatively correlated with Flathead Catfish abundance. Ongoing and future targeted surveys should help to better understand changes in the distribution and abundance of Flathead Catfish in these systems.

We summarized advancements in Flathead Catfish Pylodictis olivaris biology, fisheries, and management published from 1999 to 2021. Our goal was to highlight recent advancements in Flathead Catfish research and address information needs for this species to encourage future research. We identified and reviewed 140 papers from 33 peer‐reviewed journals, 27 theses/dissertations, and 13 technical reports on Flathead Catfish over the 23‐year period. Most studies focused on introduced Flathead Catfish populations, age and growth, movements, diet, sampling methods, and human dimensions of Flathead Catfish fisheries. The number of studies published on riverine Flathead Catfish populations was greater than the number published on reservoir populations, and many studied negative effects of populations introduced outside of the species’ native range. Flathead Catfish are most commonly found in shallow (<3‐m) locations with large woody debris or riprap and substrates with a hard bottom. Flathead Catfish movement studies identified three distinct migration periods: overwintering, prespawn/spawn, and late summer/fall, with little movement between these migrations. Flathead Catfish are typically lightly exploited (0–19% annual exploitation) and have typical (for a long‐lived species) annual total mortality rates of 11–37%, ranging as high as 62%. Flathead Catfish are most commonly sampled using low‐frequency electrofishing. Despite an increase in published literature on Flathead Catfish, information remains inadequate such that most state agencies do not follow a standardized protocol for sampling Flathead Catfish and information to guide management approaches for the species is limited. Minimal research on Flathead Catfish reproduction and spawning has occurred since 1999. Additional research is needed on these and other topics to provide information critical to managing this important species.
