“…Our movement estimates are likely biased low as a result of individual catfish having to occupy an environment for a sufficient amount of time to record an environmental shift in the otolith. Unlike telemetry studies describing catfish movements (Garrett and Rabeni, ; Tripp et al, ), we were unable to describe the exact timing and distance of individual catfish movements. Blue catfish exhibited higher movement probabilities between the MOR and MSR/TRB environments compared with channel catfish, which is consistent with other studies describing the high mobility of blue catfish (Pugh and Schramm, ; Garrett and Rabeni, ; Tripp et al, ).…”

“…Although these smaller tributaries seem to be less important in terms of recruitment, they may not necessarily be unimportant for use by other life history stages of catfishes. Several studies have indicated tributary use by older age classes in other systems that may correspond to increased feeding, growth, and survival (Garrett and Rabeni, ; Tripp et al, ). Small tributaries may provide prey subsidies to riverine fishes and confluence areas could represent beneficial habitats even if small tributaries are not significant recruitment sources.…”

“…Blue catfish is generally regarded as large‐river specialists (Graham, ; Pracheil et al, ), whereas channel catfish is more widely distributed and occupies habitats ranging from small rivers and impoundments to large rivers (Smith, ; Pflieger, ). Channel and blue catfishes may travel great distances in rivers for spawning and foraging (Graham, ; Hubert, ), and numerous telemetry studies have documented migratory behaviours and seasonal habitat use patterns of adults (Pugh and Schramm, ; Garrett and Rabeni, ; Tripp et al, ). However, knowledge of the principal natal environments and early life habitat use and movement patterns for large river catfishes is limited.…”

Insight into environments that contribute recruits to adult fish stocks in riverine systems is vital for effective population management and conservation. Catfish are an important recreational species in the Mississippi River and are commercially harvested. However, contributions of main channel and tributary habitats to catfish recruitment in large rivers are unknown. Stable isotope and trace elemental signatures in otoliths are useful for determining environmental history of fishes in a variety of aquatic systems, including the Mississippi River. The objectives of this study were to identify the principal natal environments of channel catfish Ictalurus punctatus and blue catfish I. furcatus in the middle Mississippi River (MMR) using otolith stable oxygen isotopic composition (δ 18 O) and strontium:calcium ratios (Sr:Ca). Catfishes were sampled during July-October 2013-2014 and lapilli otoliths were analyzed for δ 18 O and Sr:Ca. Water samples from the MMR and tributaries were collected seasonally from 2006-2014 to characterize sitespecific signatures. Persistent differences in water δ 18 O and Sr:Ca among the MMR and tributaries (including the upper Mississippi, Illinois, and Missouri rivers as well as smaller tributaries) were evident, enabling identification of natal environment for individual fish. Blue and channel catfish stocks in the MMR primarily recruited from the large rivers (Missouri and Mississippi) in our study area, with minimal contributions from smaller tributaries. Recruitment and year class strength investigations and efforts to enhance spawning and nursery habitats should be focused in the large rivers with less emphasis in smaller tributaries.

“…In the lower Mississippi River, tagged Blue Catfish were found 5-12 km from their release location after 363-635 d at large; unfortunately, the recapture rate of tagged Blue Catfish was low (1.4%, 3 recaptures out of 222 tagged Blue Catfish), and these results may not be representative of the species throughout its range (Pugh and Schramm 1999). In the Missouri River, 80 large Blue Catfish (mean = 872 mm TL, range = 569-1,260 mm TL) were tagged with radio tags and acoustic tags and followed for 2 years (Garrett and Rabeni 2011). Of the 24 Blue Catfish that were consistently relocated over the span of a year, migratory patterns ranged from little movement to directed movements spanning more than 100 km (Garrett and Rabeni 2011).…”

Low Apparent Survival and Heterogeneous Movement Patterns of Invasive Blue Catfish in a Coastal River

Blue Catfish Ictalurus furcatus were purposefully introduced into freshwater tributaries to Chesapeake Bay in the past, and populations have subsequently spread to new areas, negatively impacting native communities and causing concern for resource managers. To aid development of management strategies, we implemented a multiyear (2012)(2013)(2014)(2015) tagging study of invasive Blue Catfish in a 40-km stretch of the Potomac River to estimate survival and assess movement patterns. Blue Catfish (N = 1,237) were captured by electrofishing and double-tagged to allow us to estimate tag retention rates; we used reward tags to increase reporting rates. Recaptured fish (N = 104; 8.4% return rate) were at large for between 2 and 1,208 d. Tag retention rates were 0.88 (SE = 0.045) after 1 year and declined to 0.31 (SE = 0.107) after 2.7 years. The mean minimum distance moved by fish was 24.1 km (range = 0.0-112.6 km). Most (63%) fish displayed downriver movements, but distance moved was unrelated to fish size or days at large. Greater distances were observed among fish that moved downriver (34.4 km) than those that moved upriver (6.7 km). These results suggest high variability in movement behaviors for Blue Catfish inhabiting the tidal Potomac River from freshwater reaches to estuarine habitats. We estimated an annual apparent survival rate of 0.56 (SE = 0.057; Brownie tag-return model) across the study period. This survival rate is lower than survival rates reported from their native range. Long-distance movements of Blue Catfish in the Potomac River indicate that robust, large-scale control measures will be needed to reduce population abundance and minimize negative impacts of this species on native communities.

Blue Catfish Ictalurus furcatus provide a popular sport fishery in Mark Twain Lake, Missouri, but little is known about their population demographics or exploitation by anglers. Our objectives were to (1) determine population demographics of Blue Catfish, (2) determine exploitation of Blue Catfish, and (3) determine whether new harvest regulations would improve the quality (e.g., size structure and abundance) of the fishery in Mark Twain Lake. We sampled Blue Catfish by using jug lines baited with pieces of Gizzard Shad Dorosoma cepedianum, the gear used by the majority of anglers in this reservoir. Blue Catfish grew slowly, reaching a preferred size (762 mm TL) in about 12 years. Annual mortality was estimated at 24.8% using a weighted catch curve. Using reward tags, we estimated exploitation to be between 8% and 12%, and we modeled the effects of 508‐, 610‐, and 660‐mm minimum TL limits on yield and size structure of the Blue Catfish population relative to a baseline of 381 mm TL, the smallest fish usually harvested by anglers. All three length limits increased the proportion of larger fish (≥762 mm TL) in the population without reducing yield, except for slight decreases (6% and 10%) under the 610‐ and 660‐mm limits at the highest modeled natural mortality rate. We recommend the 610‐mm limit instead of the 660‐mm limit because it allows more harvest and higher yields with increases in natural mortality and still doubles the proportion of larger fish relative to the 508‐mm limit.
