Book excerpt: Traditional approaches to research and management of striped bass have tended to be mechanistic, numerically oriented, and based on limited life history information. In the study presented here, comprehensive conceptual perspective was used in a multivariate study of life history and evolutionary adaptation of 10 striped bass populations representing the full geographic and ecologic diversity of striped bass. The colonization trajectory of populations originating from a small colonizing population from the Hudson River demonstrated how striped bass adapted in varying degrees of success in their reproduction, development, behavior, survival, and trophics to a range of western North American habitats. Habitats that were marginal through infrequent suitability for successful reproduction or survival of early life stages, or through limiting longevity, resulted in life history tactics that consisted of tradeoffs between life history traits, especially reproduction and development. Fishery management effects (exploitation and stocking) and habitat effects (water temperatures, freshwater inflows, forage and pollutants) influenced life history and evolutionary adaptive capacities of all populations. Highly variable and indeterminate environments also affected these capacities and related to year-class dominance. This helped to explain declines in five of the study's populations.

Available in PDF, EPUB and Kindle. Book excerpt: Otolith studies have become more prevalent in recent years as use has expanded from ageing to examination of migration patterns and fidelity to natal habitats, and more recently examining otoliths for possible maternal contribution to progeny otoliths. The otoliths of larval Striped Bass, Morone saxatilis (Walbaum; 1792), were used to determine the presence of maternal contribution through three experiments. The first experiment was to examine the formation of larval otoliths to determine if otoliths formed prior to/ during the yolk sac stage when maternal influences are present, and thus if maternal contribution is possible. Two of the three otolith pairs (sagitta and lapillus) are formed during the embryo stage (sagitta) or post hatch (lapillus). The sagittal otoliths are the most often used otolith in microchemical studies; therefore its formation during the embryo stage suggests maternal contribution to progeny otoliths is possible. The second experiment used microchemical analysis of adult Striped Bass soft tissue (muscle, liver, kidney, and gonads) to determine whether adult Striped Bass develop trace elemental signatures similar to the adult otoliths. The gonadal tissues (ovaries and testes) were found to have similar signatures to adult otoliths utilizing a linear discriminate function analysis. As the two previous experiments support the hypothesis of maternal contribution the final step was to run a discriminate function analysis between the progeny and maternal otoliths. Embryo sagittal otoliths correctly identified the maternal clusters 91.67% of the time (n = 12), yolk sac larvae 66.67% of the time (n = 15), and non-yolk sac larvae only 60.94% of the time (n = 64). Progeny otoliths were also able to identify maternal river (Neuse, Roanoke or Tar); embryos classified the river 83.33% of the time (n = 12), yolk sac larvae classified 93.33% of the time (n = 15), and non-yolk sac larvae classified with 44.44% (n = 72) accuracy. Results of this study validate the hypothesis of maternal contribution and support the hypothesis of maternal life history determination from progeny.

This book was released on 1970 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Striped bass from the Apalachicola and St. Johns Rivers in Florida were compared taxonomically with striped bass from other drainages on the Atlantic coast and Gulf of Mexico. Both rivers contain endemic striped bass populations. The Apalachicola River population was found to be a separate race. Sexually mature striped bass from the St. Johns were induced to spawn using hormonal injections. Few fry were produced due to extreme temperature fluctuations. Reproduction requirements and factors limiting the abundance of striped bass in Florida are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: The advent of next-generation sequencing technologies has revolutionized the field of molecular ecology, facilitating increasingly fine-scale detection of genetic differences among populations and adaptationally significant mutations. In this thesis, I use genomics to advance solve longstanding mysteries of Striped Bass genetics and lay the groundwork for future studies. In the first chapter, I characterize a group of Striped Bass that were thought to be extirpated in the Saint John River, but likely survive as a remnant population. In the second chapter, I investigate connectivity and relatedness of Striped Bass populations more widely across their native range on the North American Atlantic Coast. I found that Gulf of St. Lawrence, Shubenacadie River, and Saint John River populations were all very distinct from each other and from US populations. US Striped Bass, however, could be separated into three major regions: Hudson River-Kennebec River, Chesapeake Bay-Delaware River, and Roanoke River-Cape Fear River. Demonstrating that this work is useful for management, my SNP loci were able to assign 99% of Striped Bass to these six regions, the first time Roanoke River Striped Bass have been reliably distinguished from Chesapeake Bay bass. Additionally, the presence of apparent US-origin Striped Bass on the northeastern coast of Nova Scotia raises important questions about movement patterns of Striped Bass in this area and highlights the importance of further study. In the third chapter, I used computer modelling simulations to assess the performance of four recent techniques used to find associations between phenotypes and genotypes. I found that Random Forest algorithm with population correction performed similarly to a recent, complex model implemented in confounder adjusted multiple testing. Finally, in chapter four I created 9 novel tools and used them to create an automated text-mining pipeline that can scan full-text articles and extract sentences that contain associations between genes and ecological variables. This pipeline is the first step toward improving genome annotations of non-model organisms such as Striped Bass. Together, these four chapters lay important groundwork for future genomic research both for Striped Bass and other ecologically important species.

Available in PDF, EPUB and Kindle. Book excerpt: This book is an up-to-date discussion of the culture of striped bass and other Morone spp. The subject matter is broken down into functional components of the spawning, husbandry, and economics of the industry, and is written by some of the leading scientists in each of the respective areas of discussion. The chapters on reproduction, nutrition, environmental requirements, transportation, economics and fish processing are not found anywhere else in the striped bass literature. The chapter on water quality takes a very non-traditional approach to considering the impact water quality has on the production success of Morone and offers some very thought-provoking ideas on water management.Primarily written as a reference work, this book is intended to complement existing technique manuals.

This book was released on 2015 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract Striped bass (Morone saxatilis) is an important anadromous species that provides valuable ecological and economic benefits to North Carolina. Habitat degradation, alteration and destruction are ongoing, and agencies are lacking the information needed to determine what habitat areas need protection. The North Carolina Coastal Habitat Protection Plan (NC CHPP) recommends that Strategic Habitat Areas (SHAs) be identified in order to maintain water quality and protect the ecosystem that serves our fisheries. Trace elements found in the water chemistry can be compared to elements deposited in the otolith. Otoliths, or ear bones in fish are calcified structures that incorporate elements from ambient water that is encountered by the fish. Fish residing in the AES can have a multi-elemental signature in their otoliths that can be a reflection of the water chemistry of the rivers. The temporal and spatial stability of the water chemistry must be determined before otolith chemistry can be used to establish nursery habitat. The temporal and spatial stability of water chemistry in each watershed of the AES was examined over multiple sampling sites and seasons. Sr:Ca, Ba:Ca, Mn:Ca, and Mg:Ca ratios differed significantly spatially, but not temporally (with the exception of Mg:Ca) and multi-element signatures correctly identified habitats with between 79-89% accuracy. Once the spatial and temporal stability of the water chemistry was evaluated, otoliths of adult striped bass were analyzed to determine SHAs used in their first summer of life. Adult striped bass were collected from Albemarle Sound and Roanoke River during the pre-spawn through post-spawn period from March-May of 2009 and 2010. Concentrations of strontium (Sr), barium (Ba), manganese (Mn), and magnesium (Mg) at the 60-120 day post-hatch period in adult otoliths were measured to determine habitat specific signatures and to establish the relative contribution of fish from each nursery habitat. Random Forests (JMP Pro 11.2) analysis was applied to otolith chemistry to successfully assign adult fish to one of four watershed containing nursery habitat. Model testing was completed by analyzing the juvenile (60-120 days post-hatch) portions of the adult otoliths from the 1994 to 2006 year classes (Age 3 to Age 16; n = 206). Results indicate the highest portion (60.87% to 76.47%) of adult striped bass sampled in my study were predicted to have used the Perquimans River as their nursery habitat area and subsequently survived to spawn as adults. Only a small portion of the Perquimans River is currently designated. My study results indicate that the Perquimans River appears to be important striped bass nursery habitat and therefore needs additional protection. Management implications resulting from changes in current SHA designations are discussed, not only for striped bass sustainability via the NC CHPP but also for the furtherance of existing additional environmental management programs or initiatives (e.g., the Albemarle Pamlico National Estuary Partnership's Comprehensive Conservation and Management Plan [CCMP], and the South Atlantic Landscape Conservation Cooperative's Conservation Blueprint 2.0).

This book was released on 2013 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to properly manage striped bass within a geographic area, it is necessary to understand the genetic relationships of striped bass populations within and between watersheds to identify appropriate management units. Determining temporal changes in genetic relationships as well as the genetic characteristics of the populations is important in understanding how stock enhancement may have and continues to influence population units. A suite of 12 microsatellites was used to evaluate patterns of striped bass gene flow both spatially and temporally across the watersheds of North and South Carolina. Populations from the study watersheds were genetically diverse with the exception of the Savannah River which is recovering from a major population decline. Striped bass in the Roanoke and Cape Fear rivers represented a single population, most likely due to historical transfer stocking across the state from Roanoke River stock. Watersheds in South Carolina contained genetically distinct striped bass populations, although the difference between striped bass populations in the ACE and Santee-Cooper watersheds has substantially decreased over fifteen years, likely due to the stocking of Santee-Cooper fish into the ACE Basin. Conversely, supportive stocking of the Santee-Cooper system has helped to maintain genetic diversity of the population. The striped bass populations of the Carolinas are good examples of the various positive and negative effects from stock enhancement that must be considered and monitored when implementing or assessing a stock enhancement program.

Available in PDF, EPUB and Kindle. Book excerpt: Although the hybrid striped bass (HSB; female white bass, Morone chrysops x male striped bass, M. saxatilis) supports the fourth most valuable form of finfish aquaculture in the United States, neither parental species has been genetically improved. Expansion of the HSB industry is limited by culture inefficiencies associated with reliance on wild broodstock for annual fingerling production. Domestication and selective breeding are expected to increase production efficiency and to promote market expansion. Resource limitations currently prohibit the individual rearing of multiple larval families for striped bass performance testing, necessitating a breeding program that is based on communal rearing of progeny groups with molecular markers as genetic tags for offspring identification. This dissertation research addresses fundamental questions relevant to selective breeding of the male parent of the HSB, the striped bass, including: (1) Evaluation of genetic variation within a captive striped bass broodstock population; (2) Examination of the feasibility of communal rearing protocols based on microsatellite markers for progeny identification during performance evaluations of striped bass; (3) Assessment of paternal variation in performance traits of striped bass at both research and commercial scale throughout the HSB production cycle. Examination of three captive striped bass broodstock strains using three highly variable microsatellite markers revealed that the broodstock population contains moderately high genetic diversity, with an average allelic richness of 13.7 alleles per locus and an average observed heterozygosity of 0.84. Crosses among the three differentiated strains should provide a valuable starting point for establishing a highly variable base population for selective breeding. Twenty-four experimental families were produced from captive, genotyped broodstock for communal evaluations of progeny survival and performance. Parentage was determined by micros.

Book excerpt: This is a revealing glimpse into the life history strategy of Hudson River-origin striped bass (Morrone saxatilis), based on surprising observations carried out over a personal 10-year (1997-2006) tag and release (T/R) study, in which better than 15,000 over-wintering fish were marked for science in the Thames River, CT. Eight other northeast O-W contingents are profiled, seasonal problems are identified, spin, fly and trolling techniques are discussed, and frequently asked questions about the fish and their tagging are addressed. Consequently many related riddles are solved, along with reasons why the author has long been involved with fisheries research. With this information in hand, you won't have to wait till spring to resume your striped bass fishing. Juvenile, as well as adult members of this regions most popular game fish use numerous estuaries to over-winter in. Closer to home than imagined, they offer an Rx for cabin fever symptoms. Their wintertime biology and reasons for it, how to catch them, where summertime travels take them, along with many other secrets are profiled. Much of which is supported by previous fisheries research presented in a "common language" that any angler understands. It's a book filled with surprising insights and relationships all saltwater anglers will enjoy.

Available in PDF, EPUB and Kindle. Book excerpt: Striped bass, Morone saxatilis, is one of the most thoroughly studied anadromous fish species in the United States, with records governing the management of the species dating back to the late 1600s. However, management of this species has been difficult because of the species' anadromous behavior that takes it between fresh and marine waters, crossing numerous geopolitical boundaries. In the 20th century, the fishery experienced two dramatic declines in abundance. Studying the fishery after the declines resulted in major advancements in scientific understanding and management for this species, and striped bass is now an example of a successfully rebuilt fishery, key questions about population dynamics and migration patterns still persist. These unanswered questions reduce confidence in managing the species as a whole, and instead encouraging precautionary measures applied to small geographic areas, such as a natal river. This dissertation begins with a thorough review of the history of striped bass, including the key scientific findings and management measures instrumental in its recent recovery. Chapter 2 explores how scientists have approached the major challenge in striped bass management: defining the management unit so allocations can be made fairly and sustainably. The array of genetic techniques that have been employed, their limitations, and the populations studied with those techniques, is reviewed. Among the studies reviewed is one suggesting North Carolina striped bass migration may be genetically linked; this suggestion forms the basis for this dissertation's hypothesis. Answering this question can help resource managers better understand population dynamics, genetic interplay, and migration patterns - important for creating effective management and fair allocation between states. Chapter 3 explores the biotic and abiotic factors that can influence the results of an otolith microchemistry analysis, and Chapter 4 contains the discussion of the findings about the 112 striped bass examined. With biases accounted for, this dissertation concludes that marine migration was not linked to the genes examined. However, an interesting post-hoc observation can be made: though the behavior was not found to be genetically linked, striped bass in the first year of life proved to be residents, stagers, or sprinters, with different growth rates associated with these behaviors.
