Book Reproduction of Smallmouth Bass Micropterus Dolomieui in Bull Shoals Lake Arkansas

Download or read book Reproduction of Smallmouth Bass Micropterus Dolomieui in Bull Shoals Lake Arkansas written by Louis E. Vogele and published by . This book was released on 1981 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smallmouth bass were studied in Bull Shoals Lake to determine the nesting requirements and reproductive capabilities of the species in a reservoir. Underwater observations were conducted weekly in five study areas during the spawning seasons of 1969-76. Length of spawning season was affected by the rate of water temperature rise during the nesting period. Active nests were found at ambient temperatures of 13.3-22.5 degrees Centigrade. Nest were generally on gently sloping rock and gravel bottoms, beside permanent objects such as rocks or sunken logs, and at densities of less than one per 100 m of shoreline.

Book Factors Impacting Survival Following Parental Care in Male Smallmouth Bass Micropterus Dolomieu

Download or read book Factors Impacting Survival Following Parental Care in Male Smallmouth Bass Micropterus Dolomieu written by Brian Okwiri and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parental care in animals is associated with a high cost of reproduction and hence is linked to high mortality among parents between reproduction episodes. Post-care mortality risk is linked to a variety of causes, including depleted energy reserves and diminished condition, both of which increase the risk of mortality by starvation. However, the magnitude of this risk is expected to vary based on the size of the individual due to metabolic allometry. Further, parents may adjust the care levels based on their current status and the body size-metabolic allometry as a trade-off between current and future reproduction. Here, I leverage a decade-long dataset on the paternal behavior and survival of male smallmouth bass, Micropterus dolomieu, a temperate freshwater fish, to explore how body size and parental behavior at first reproduction by 3-year-old males influenced their future survival. The results logistic regression suggest that future survival was influenced by both body size and parental behavior. Two of three equally parsimonious models included a direct influence of male body size on survival, with higher survival of larger individuals, and one of these two models also included a term associated with male parental behavior, where--consistent with a trade-off between current and future reproduction--lower site tenaciousness was associated with higher survival. The third of the three models included these terms and their interaction, where more site tenacious smaller males had higher survival. The mediation of parental behavior by body size implied by the latter model suggests that small, site tenacious males may be more likely to survive post-reproduction because they expend less energy in response to disturbances while on the nest or may, through bold behavior in other contexts, better recover energy lost in the parental care period. The model also highlights the potential complexity of interactions between behavior and individual physical attributes on survival.

Book Population Dynamics of Smallmouth Bass Micropterus Dolomieu in Response to Habitat Supply

Download or read book Population Dynamics of Smallmouth Bass Micropterus Dolomieu in Response to Habitat Supply written by Cindy Chu and published by . This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A smallmouth bass habitat model was developed to estimate how changes in habitat may affect smallmouth bass populations. Habitat characteristics such as mean annual air temperature and substrate were used to determine the spatial distribution of nests, juveniles and adults throughout a lake. Growth is density-dependent for all life stages. Mortality is size-dependent in the young-of-the-year (YOY) but is set at a constant annual rate for older fish. Sensitivity analyses revealed that increases in mean annual air temperature, total dissolved solids concentration and the area available for nesting increased the density of the simulated population. Furthermore, a YOY bottleneck exists in smallmouth bass populations and the nesting habitat appears to be more important than the juvenile/adult habitat. Model predictions were compared to data from Lake Opeongo, Ontario and Long Point Bay, Lake Erie. This revealed that the model can be applied to estimate how habitat changes influence fish density but requires modification before it can be used to predict the spatial distribution of nests and fish within a lake.

Book Reproductive Fitness of Smallmouth Bass Micropterus Dolomieu Under Heterogeneous Environmental Conditions

Download or read book Reproductive Fitness of Smallmouth Bass Micropterus Dolomieu Under Heterogeneous Environmental Conditions written by Ryan Patrick Franckowiak and published by . This book was released on 2017 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Identifying the biotic and abiotic factors that influenceindividual reproductive fitness under natural conditions is essential for understanding important aspects of a species? evolutionary biology and ecology, population dynamics, and life-history evolution. Using next generation sequencing technology, I developed five microsatellite multiplex reactions suitable for conducting large scale parentage analysis of smallmouth bass, Micropterus dolomieu, and used molecular pedigree reconstructiontechniquesto characterize the genetic mating system and mate selection inadult smallmouth bass nesting in Lake Opeongo, Ontario, Canada. I used multivariate spatial autocorrelation analysis to indirectly infer the occurrence and extent of natal philopatry among spawning adults, to assess the strength and direction of sex-bias in natal dispersal patterns, and to evaluate the degree of nest site fidelity and breeding dispersal of spawning adults. I also evaluatedhow differences in littoral zone water temperature caused by wind-induced seiche events influence the relative reproductive success of spawning adults. Lastly, I provide a synopsis of potential future research aimed at further exploring factorsthatinfluence the reproductive fitness of smallmouth bass in Lake Opeongo. This information will contribute to our understanding of the factors regulating smallmouth bass populations, and provide insight into the factors controlling the variance in individual reproductive success and thus recruitment dynamics in this species.

Book Factors Affecting Nesting Success in Florida Bass Micropterus Floridanus

Download or read book Factors Affecting Nesting Success in Florida Bass Micropterus Floridanus written by Zachary Joseph Slagle and published by . This book was released on 2014 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bed fishing in Florida Bass Micropterus floridanus fisheries has made nest survival a topic of interest for managers, but Florida Bass nesting has rarely been studied. My objectives were to determine what habitat and temporal characteristics (substrate, depth, water temperature) Florida Bass seek for nesting, to estimate nest survival, and to examine factors that influence nest survival to the swim-up fry stage. Four lakes were snorkeled in north-central Florida each year between 2010-2013 to survey bass nests. Snorkelers found 313 nests, of which 75% were found on vegetation. Guarding male fish were only seen on 64% of active nests, indicating lower nest fidelity than has been reported in other Micropterus spp. Florida Bass daily nest survival was estimated at 0.885. The most important factors in determining nest success were presence of a male bass and depth of the nest, whereas sizes of the male bass and of the brood were less important. Habitat and temporal characteristics had minimal effects on nest survival. Stunted growth in the study populations could have decreased power of male size for statistical tests. My results indicate lower nest fidelity for Florida Bass than has been reported for other black basses, but presence of the male was the most effective predictor of nest success.

Book The Effects of Angling Stress on Smallmouth Bass Micropterus Dolomieu in Lake Erie New York

Download or read book The Effects of Angling Stress on Smallmouth Bass Micropterus Dolomieu in Lake Erie New York written by Joshua D. Prey and published by . This book was released on 2002 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smallmouth bass are among the most abundant and popular game fish in lake Erie. Therefore, it is important to understand as much as possible about these local populations to improve sport fishery quality. This thesis offers an overview on spawning estimations and the effects of angling stress on smallmouth bass. Young-of-the-year (YOY) bass were collected and aged to back-calculate spawning. Hatching times ranged from June 5 to June 19 for the 1999 spawning season. Angling stress was assessed by measuring nest return time and by physiological change. As handling time increased nest return time increased allowing young to be exposed to high risk of predation. ATP concentrations decreased as handling time increased indicating less energy to effectively guard a nest. These findings, along with a changing Lake Erie ecosystem, may threaten the smallmouth population causing recruitment to decrease as predation increases. Author abstract.

Book Captive and Wild Observations of the Courtship and Spawning Behavior of Guadalupe Bass Micropterus Treculii

Download or read book Captive and Wild Observations of the Courtship and Spawning Behavior of Guadalupe Bass Micropterus Treculii written by Edward James Enriquez and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Guadalupe Bass Micropterus treculii is native to the Texas Hill Country of central Texas. It is distributed across portions of the Brazos, Colorado, Guadalupe and San Antonio River basins. The Guadalupe Bass is threatened by hybridization with non-native smallmouth bass Micropterus dolomieu. Because pure bred Guadalupe Bass are increasingly harder to find in areas where Smallmouth Bass have become established, Texas Parks and Wildlife Department developed a captive spawning program for Guadalupe Bass for supplemental stocking to counter the influence of hybridization. To determine potential mechanisms influencing hybridization in Guadalupe Bass populations, objectives were: (1) characterize nesting habitat and behavior, (2) compare courtship behaviors in native and hatchery environments, and (3) identify behaviors potentially influencing genetic diversity in offspring of hatchery fish. Initial field studies included snorkeling and visual surveys conducted during September and November in 2012 in Gorman Creek, South Llano River, Pedernales River, and the Guadalupe River; no active nests or reproductive adult Guadalupe Bass were observed. During February through May of 2013, visual surveys were repeated at the four field sites. In addition courtship and spawning behavior of Guadalupe Bass were recorded at A.E. Wood Hatchery. In both hatchery and natural environments, previously undocumented reproductive behaviors were observed. Breeding color patterns of males and females became more differentiated, aggressive behavior of males included opercular flaring and jaw locking, and individual males courted multiple females simultaneously and syntopically at nest sites. Only 50% of the available nesting mats were used because of the monopolization of females and nest sites by a few males. Frequencies were significantly different for several male and female behaviors when comparing hatchery to natural environments. The prototypical courting and spawning sequence of the Guadalupe Bass were visually represented in kinematic diagrams. Although behavioral sequences were similar in hatchery and natural sites, certain transition probabilities differed. Potential mechanisms for hybridization were: similar color pattern changes in males and females of both species, female preference in both species for larger males, similar use of nesting habitat in both species, similar reproductive behavioral repertoire, and the monopolization of nesting sites and females by males.

Book BEHAVIOR OF SYMPATRIC YOUNG OF THE YEAR SMALLMOUTH BASS MICROPTERUS DOLOMIEU AND INVASIVE ROUND GOBY NEOGOBIUS MELANOSTOMUS IN THE PRESENCE OF A POTENTIAL PREDATOR

Download or read book BEHAVIOR OF SYMPATRIC YOUNG OF THE YEAR SMALLMOUTH BASS MICROPTERUS DOLOMIEU AND INVASIVE ROUND GOBY NEOGOBIUS MELANOSTOMUS IN THE PRESENCE OF A POTENTIAL PREDATOR written by Jamie L. Russell and published by . This book was released on 2018 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the species-interaction level, invasive species can change the behavior, and ultimately the survival of certain native species. Notably, the invasion of the Great Lakes by the Round Goby (Neogobius melanostomus) in the early 1990s has raised questions regarding the impact they have on native Smallmouth Bass (Micropterus dolomieu), which occupy the same habitat. Round Gobies (RG) are known to aggressively evict young Smallmouth Bass (SMB) from shelter habitats and epibenthic substrate, which could lead to reduced growth, increased predation risk, and ultimately, population decline. I quantified the behavior of young SMB, in terms of shelter use, in the presence of invasive Round Gobies in comparison to native Logperch (Percina caprodes) (LP) with a replicated experiment set up in small pools with PVC pipe shelters. Time spent in shelter was measured using video footage. In the presence of Round Gobies, with or without a predator present, SMB spent little to no time in the shelter (0.019 and 10.09 percent, respectively). An increase in shelter use by the SMB occurred in the presence of LP and when in the presence of a predator and no other species. SMB were unable to remain in the shelter in the presence of Round Gobies because they were aggressively evicted, which is an indication that behavior of young-of-the-year Smallmouth Bass is negatively affected in the presence of Round gobies.
