Available in PDF, EPUB and Kindle. Book excerpt: The highly anticipated second volume of Freshwater Fishes of North America, a monumental, fully illustrated reference that provides comprehensive details on the freshwater fishes of the United States, Canada, and Mexico. When the first volume of Freshwater Fishes of North America was published, it was immediately hailed as the definitive reference in the field. Readers have been fervently awaiting the next volume in this encompassing three-book set ever since. Now complete, volume 2, covering families Characidae to Poeciliidae, is the result of decades of analysis by leading fish experts from universities and research laboratories across North America. Each volume in this authoritative synthesis covers the ecology, morphology, reproduction, distribution, behavior, taxonomy, conservation, and the fossil record of the included North American fish families. The encyclopedic reviews of each family are accompanied by color photographs (nearly 250 in this volume alone), range maps, and artwork created by noted fish illustrator Joseph R. Tomelleri. The result is a rich textual and visual experience that covers everything known about the diversity, natural history, ecology, and biology of North American freshwater fishes. Volume 2 covers the following North American families of fishes: Characidae (Characins) Ictaluridae (North American Catfishes) Ariidae (Sea Catfishes) Heptapteridae (Three-barbeled Catfishes) Osmeridae (Smelts) Esociformes (Esocidae, Pikes and Umbridae, Mudminnows) Percopsidae (Trout-perches) Amblyopsidae (Cavefishes) Aphredoderidae (Pirate Perches) Gadidae (Cods and Cuskfishes) Mugilidae (Mullets) Atherinopsidae (New World Silversides) Beloniformes (Needlefishes and Halfbeaks) Rivulidae (New World Rivulines) Profundulidae (Middle American Killifishes) Goodeidae (Goodeids) Fundulidae (Topminnows) Cyprinodontidae (Pupfishes) Poeciliidae (Livebearers) The chapter authors of Volume 2 are: Gianetta Adams Clyde Barbour Micah Bennett Ricardo Bentancur-R.

Download or read book Movement Habitat Use and Spawning Characteristics of Flathead and Blue Catfish on the Lower Missouri River and Tributaries written by Daniel L. Garrett and published by . 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 (

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.

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.

Download or read book Quantifying Patterns and Select Correlates of the Spatially and Temporally Explicit Distribution of a Fish Predator Blue Catfish Ictalurus Furcatus Throughout a Large Reservoir Ecosystem written by Zachary James Peterson and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding how and why fish distribution is related to specific habitat characteristics underlies many ecological patterns and is crucial for effective research and management. Blue Catfish, Ictalurus furcatus, are an important concern for many fisheries agencies; however, lack of information about their distribution and habitat use remains a hindrance to proper management. Here, over all time periods and across months, I quantified Blue Catfish distribution and environmental correlates of distribution in Milford Reservoir, the largest reservoir in Kansas. I tested relationships among acoustically tagged Blue Catfish and three groups of variables postulated to influence Blue Catfish distribution in the literature (i. localized microhabitat variables, ii. larger-scale mesohabitat variables, iii. biotic variables). Blue Catfish were consistently aggregated in two locations of the reservoir across five months during summer and fall, 2013. Using multiple linear regression and an information theoretic model selection approach, consistent correlates of distribution included localized, microhabitat variables (i.e., dissolved oxygen, slope) larger-scale, mesohabitat variables (i.e., distance to channel, river kilometer from the dam) and a biotic variable (i.e., Secchi depth). This research identified which 5 of the 12 variables identified in the literature were most influential in determining Blue Catfish distribution. As a guide for future hypothesis generation and research, I propose that Blue Catfish distribution was driven by three ecologically-relevant tiers of influence. First, Blue Catfish avoided extremely low dissolved oxygen concentrations that cause physiological stress. Second, Blue Catfish aggregated near the channel, an area of bathymetric heterogeneity that may offer a foraging advantage. Third, Blue Catfish aggregated near low Secchi depths, shown here to be associated with increased productivity and prey abundance. Building on my results, future research into the distribution and habitat use of Blue Catfish should incorporate aggregated distributions of fish into research designs, focus on how both small and large scale relationships interact to produce patterns of distribution, and explore further the mechanisms, consequences, and interactions among the three tiers of influence identified here.
Download or read book An Evaluation of the Lower Ohio River Channel Blue and Flathead Catfish Fishery written by Devon C. Oliver and published by . 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.
