This book was released on 2003 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: The movements and habitat use patterns of adult flathead catfish were studied in two Missouri interior streams via radiotelemetry. At the largest spatiotemporal scale investigated, annual movements patterns included seasonal migrations commonly tens of kilometers long between overwintering, prespawn and spawning habitats, and postspawn feeding and growth habitats. Spatial variation in annual cycles within and between the Grand River and the Cuivre River were observed. Seasonally, fish moved the least during an overwintering period, moved the most during the prespawn/spawning period of spring and early summer, which was followed by a third period of restricted movements during late summer and fall. Habitat use during the overwintering period was investigated in the Grand River and the adjoining reach of the Missouri River using a river habitat mapping system operated by the U.S. Geological Survey. During the postspawn restricted movement period, the home range of fish in both rivers were determined using univariate kernel density estimation. Home-range sizes were variable (median = 1085 m; range = 70-69090 m), and no differences between fish size classes, sexes, or rivers were evident. Habitat use was considered in an information-theoretic framework in which an exploratory all-subsets logistic regression analysis ranked the relative importance of 13 measured habitat components. Components of cover (especially large woody debris) and depth were found relatively more important than measures of velocity and substrate. Habitat use regression models from each river were evaluated and predicted well when applied to out-of-sample data from the other river. Diel activity patterns and 24-hour movement paths were presented. An appendix provides methodological information on univariate kernel density estimation in rivers and streams.

This book was released on 2010 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: The movement and habitat use patterns of adult flathead and blue catfish were studied via acoustic and radio telemetry in the lower Missouri River and adjacent tributaries including the Grand, Lamine, Chariton, and Little Chariton Rivers. At the largest spatiotemporal scale, annual movement patterns varied greatly from restricted-movement behavior throughout the annual cycle to seasonal migrations commonly tens of kilometers between habitats used for spawning, feeding and growth, and overwintering. Fish moved the least during the overwintering period and the most during the prespawn/spawn period, followed by a third period of restricted movement during the summer and early fall. The diversity in life history strategies suggests that populations of large-river catfish use resources at multiple spatial scales, from the reach to the watershed, to meet life requisites. Diurnal home range and resource selection was investigated during the summer/fall restricted-movement period; an ecologically relevant time frame with respect to feeding and growth. With the exception of few, both species established small home ranges (

Available in PDF, EPUB and Kindle. Book excerpt: The flathead catfish Pylodictis olivaris is a large piscivorous carnivore that has been widely introduced beyond its native range. I studied the behavior of a flathead catfish population that has recently inhabited a section of the Deep River, North Carolina (in the upper Cape Fear River basin), and currently coexists with the federally endangered Cape Fear shiner Notropis mekistocholas. This coexistence raises concerns of predation risks of the flathead catfish on the Cape Fear shiner. I radio-tagged 24 adult flathead catfish in the Deep River between Carbonton and Highfalls dams and monitored their behavior from June 2004 to August 2005. Fish were tracked weekly to determine seasonal patterns, and subsets of those were tracked once per hour for a 24-hour period to determine diel patterns. Eight of the fish were captured, tagged, and released in the upstream, shallow section of the river, and 16 in the deep, downstream, impounded section. A majority of the tagged fish either quickly moved into or stayed in the downstream, impounded section for the entire study period. Flathead catfish selected microhabitats non-randomly annually and within three functional seasons (spawning, growth, and winter). Flathead catfish were usually associated with habitats that were relatively deep (3-6 m), slow in velocity, over bedrock substrates, and nearly always in or adjacent to coarse woody debris or associated with no cover. Among seasons, these fish utilized different habitats, with faster bottom velocities during the spawning season, silt/clay substrates and faster mean column velocities in the growth season, and in the winter season, they occupied the deepest water available and most frequently, not associated with any cover type. I calculated estimates of seasonal home range as linear home range and kernel density estimates (99%, 95%, 90% and 50%). Flathead catfish mean linear home ranges were greater than 16 km annually, and mean seasonal ranges were 13.1 km during spawning.

This book was released on 2014 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: The popularity of catfish Ictaluridae nationally as a sport fish is well documented and angling for catfish on the Missouri River in Nebraska (NMR) is especially popular. Catfish monitoring program by the Nebraska Game and Parks Commission (NGPC) began in 1974 and several short-term evaluations of Channel Catfish population dynamics have been performed. However, no long term analyses of population characteristics have been conducted since the early 1990s. The focus of this research was to summarize the status of Channel Catfish populations in the NMR and give recommendations for future management. I summarized population characteristics, modeled length limit regulations, and assessed the feasibility of a survey design aimed at gathering effort and catch data from setline anglers. Population characteristics varied among the four reaches studied. Channel Catfish in the upper unchannelized reach had relatively low mortality, moderate population densities and a long life span. The lower unchannelized reach had a population of small, slow growing Channel Catfish with high mortality rates. Population characteristics in the upper channelized reach were similar to those of the lower unchannelized reach except relative abundance was greater. The lower channelized reach had the highest mortality and the fastest growing, shortest lived fish in the study. Modeling revealed all reaches except the lower unchannelized reach could benefit from a 380-mm minimum length limit. In all cases, mean total length, mean weight, and yield would increase with a minimum length limit. A maximum length limit would likely not be effective for growing trophy sized fish in the upper unchannelized reach. Setlining is an unknown aspect of the Missouri River catfish fishery, and methods described in this study appear to be a feasible alternative to traditional creel surveys for estimating setline effort and catch.

This book was released on 2021 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2015, Illinois changed size and harvest limits for catfishes (blue catfish Ictalurus furcatus, flathead catfish Pylodictis olivaris, and channel catfish Ictalurus punctatus) in the Ohio River to match those of neighboring states in order to provide continuity of the regulations and promote a trophy catfish fishery. Regulations imposed a daily limit of one blue catfish or flathead catfish ≥ 35 inches (88.9 cm) and one channel catfish ≥ 28 inches (71.1 cm) per fisher and a 13 inch (33.0 cm) minimum length limit for all species with no bag limit. Although management regulations were implemented, potential efficacy of the implemented regulations and appropriate (i.e. most precise or accurate with fewest samples) monitoring protocols were unknown. Furthermore, there was general lack of understanding of early life movements, natal dispersal timing and principal recruitment sources that aide in determining appropriate spatial scale for monitoring and managing lower Ohio River catfish stocks. To fill these knowledge gaps the following methods were employed: 1) simulation modeling was used to evaluate precision in estimating catch and size distribution metrics for monitoring population trends with increasing sample size (i.e., sampling events), 2) N-mixture modeling was used to estimate size selectivity of multiple gears using detection probability as a robust alternative to size-specific catchability coefficients, 3) otolith microchemistry (Sr:Ca and Ba:Ca) was employed to determine principal recruitment sources, early life movement patterns, and provide fisheries managers with a better understanding of the spatial extent to which management actions should be implemented, 4) Bayesian modeling was used to estimate growth and mortality, 5) Yield-per-recruit modeling was used to estimate and evaluate fishing mortality rates that would result in growth overfishing (FMAX) and yield at FMAX (YPRMAX) for three management scenarios (no regulation, minimum length limit [33.0 cm or greater] and a permissive slot limit [33.0 cm-88.9 cm; blue catfish and flathead catfish]). The simulation models presented account for the uncertainty associated with heterogeneous selectivity of a gear, and minimize the impact of rare or extreme catch values. Trotlines and low pulse (15-pps) electrofishing generally required the fewer samples to achieve stable values of catch per unit of effort (CPUE), proportional size distribution (quality; PSDQ), and coefficient of variation (CV) than other gears based on simulation modeling. Abundance and detection probabilities were estimated separately for each species of catfish by length category within and across gears, producing a species-gear-size correction for catch bias used in estimating Proportional Size Distribution-Quality (PSDQ). Corrected (i.e., accounting for detection) PSDQ values were lower than uncorrected estimates suggesting a positive bias for larger fish across the entire sampling regime. Managers should use a combination of low pulse electrofishing, trotlines, and high pulse (60-pps) electrofishing in their monitoring efforts for all three species. Based on microchemistry, ictalurid catfishes in the lower Ohio River appear to recruit from multiple sources and make movements across a broad geographic scale. Additionally, some catfish may be originating from outside the portion of the Ohio River that is managed by Illinois (lower 214 km). Fisheries managers should take this into account when implementing management actions. However, most ictalurid catfishes originated from riverine (e.g., Ohio and Mississippi River) natal environments and not from smaller tributaries, and managers should not expect tributaries to compensate for weak year-classes within the river. Based on yield per recruit modeling, catfish stocks are unlikely to benefit from current regulations or a theoretical minimum size limit given the near complete overlap of YPRMAX confidence intervals for all estimable scenarios and the small statistical difference (1-3%) based on FMAX between the most permissive and most restrictive scenarios. While statistical differences in FMAX exist, they are likely biologically irrelevant, exceeding the precision of estimation methods for F. While there is some indication that alignment and continuity of management regulations is warranted based on microchemistry, the efficacy of the current permissive slot regulations is questionable based on the models presented and the life history of these fishes. There is no advantage to implementing any of the modeled regulations in terms of increasing FMAX or YPRMAX.
