This book was released on 2014 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: Striped Bass, Morone saxatilis, is an anadromous, recreationally and commercially important fish species found throughout the U.S. Atlantic east coast, whose migrations have been intensely studied. A review of the relevant literature on Striped Bass migrations revealed that the paradigm of Striped Bass migration along the U.S. Atlantic coast should be updated, as new information has shown that in addition to the Chesapeake Bay and Hudson River, the Roanoke River, NC, Delaware River, and possibly the Shubenacadie River, Nova Scotia, Canada, may also contribute fish to the mixed Atlantic Migratory Stock. The needs for an updated delineation of stocks that contribute to the Atlantic Migratory Stock and determination of inshore migrations and habitat use were identified as additional avenues for further research. In effort to answer the latter question, the inshore movements and potential mixing of North Carolina stocks of adult Striped Bass from separate management areas (Albemarle Sound Management Area, ASMA, and Central Southern Management Area, CSMA) were determined using otolith microchemistry. Trace element ratios (strontium:calcium, Sr:Ca; barium:calcium, Ba:Ca; magnesium:calcium, Mg:Ca; and manganese:calcium, Mg:Ca) measured through inductively coupled plasma optical emission spectrometry (ICP-OES) from ASMA and CSMA water samples were used to determine that each management area had different water chemistries through linear discriminant function analysis (LDFA), allowing for discrimination of otolith chemistries of fish from different management areas. Adult otolith elemental concentrations of Sr, Ba, Mg, and Mn, measured using laser ablation inductively couple plasma mass spectroscopy, of fish from separate management areas were compared using linear discriminant function analysis, which determined that little mixing of adult fish occurred between the two management areas, except in years of high abundance of ASMA fish, in which those fish would migrate to the CSMA. The same methods were used on CSMA fish determined to be of hatchery or wild origin by Dobbs (2013) to determine that CSMA hatchery and wild fish use different habitat during their sub-adult and early adult lives, but similar habitat as they aged. Finally, otolith microchemistry was used in an attempt to determine if the Roanoke River, NC (ASMA) contributed fish to the Atlantic Migratory Stock, as North Carolina Division of Marine Fisheries (NCDMF) tag returns indicated the Roanoke River was contributing significant numbers of fish. Otolith Sr:Ca ratios were used to determine anadromous migrations, as otolith Sr:Ca is directly correlated to ambient salinity. Results did not agree well with NCDMF tagging, as many larger fish exhibited resident Sr:Ca profiles, whereas NCDMF tag returns indicated that most, larger (>800 mm total length, total length) fish were anadromous and undertook long distance migrations. It is possible that the Roanoke River harbors discrete resident and anadromous contingents of large, adult Striped Bass.

Book Natal Origin of Central Southern Management Area  North Carolina Striped Bass  Inferred from Otolith Microchemistry

Download or read book Natal Origin of Central Southern Management Area North Carolina Striped Bass Inferred from Otolith Microchemistry written by Jeffrey M. Dobbs and published by . This book was released on 2013 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Striped bass (Morone saxatilis) is an important commercial and game fish throughout North Carolina coastal waters. These fish have spawning populations present in all of the state's coastal rivers, however populations south of the Albemarle Sound in North Carolina have rarely been studied. These populations lie within North Carolina's immense Central Southern Management Area (CSMA). The CSMA stretches from the northernmost point of Pamlico Sound in the north down to the South Carolina border in the south. There are three main watersheds in the CSMA: the Tar/Pamlico River, the Neuse River, and the Cape Fear River. These rivers have spawning populations of striped bass, yet very few age 0 fish have been collected to support this in recent years. My study investigated the natal origin of CSMA striped bass through the use of water and otolith elemental analyses. Surface water samples and environmental data were collected once per month from 15 sample sites throughout the CSMA from May 2011 to July 2012. Two additional sample ponds from Edenton National Fish Hatchery were sampled once per week for two weeks in April 2012. Samples were analyzed for concentrations of calcium (Ca), strontium (Sr), magnesium (Mg), barium (Ba), and manganese (Mn) using an inductively-coupled plasma optical emission spectrometer. Concentrations were recorded as element to Ca ratios to account for the role of Ca in otolith deposition. Salinity differed significantly by location, while temperature and dissolved oxygen differed significantly by month and season. Only temperature differed significantly by year. All measured elements were consistently detected at every sample site. All measured elements differed significantly by location, but only Mn differd by month, season, and year. A multivariate classification of samples to their river of origin yielded only 42% success. When the classification was narrowed to include only one low salinity sample site per river, samples were classified to their sample site of origin with 82% accuracy. Fish (N=251) were collected from the Neuse and Tar/Pamlico rivers from April 2011 to April 2012. Fish total length (TL), total weight (TW), gonad weight, and liver weight were collected to calculate relative weight (Wr), liver somatic index (LSI), and gonadal somatic index (GSI). Otoliths were removed for ageing and elemental analysis. Elemental analysis was conducted by measuring concentrations of Sr, Mg, Mn, and Ba in the natal origin region of the otolith using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). Condition of fish collected in the Neuse and Tar/Pamlico was sub-optimal. Fish GSI follow predictable yearly cycles, but were maturing a full year earlier than Roanoke River striped bass. Using the Sr signature from otolith elemental analysis, 88.4% of fish originated from the hatchery. Fish determined to be of natural origin were classified to their river of origin with 58.0% accuracy, and to their management area of origin with 84.0% accuracy. This study suggests that striped bass has become a put and take fishery in the Neuse and Tar/Pamlico rivers.

Book Taxonomic Status and Reproduction of Striped Bass  Morone Saxatilis  in Florida

Download or read book Taxonomic Status and Reproduction of Striped Bass Morone Saxatilis in Florida written by James M. Barkuloo and published by . 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.

Book Maternal Input of Striped Bass  Morone Saxatilis

Download or read book Maternal Input of Striped Bass Morone Saxatilis written by Brie Elking and published by . This book was released on 2014 with total page 136 pages. 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.

Book Past and Present Genetic Structure of Striped Bass  Morone Saxatilis  in the Carolinas and Effects from Stock Enhancement

Download or read book Past and Present Genetic Structure of Striped Bass Morone Saxatilis in the Carolinas and Effects from Stock Enhancement written by Andrew Patrick Anderson and published by . 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.

Book Historical Ecology of Striped Bass Stocking in the Southeastern United States

Download or read book Historical Ecology of Striped Bass Stocking in the Southeastern United States written by Jennifer Rebecca Woodroffe and published by . This book was released on 2012 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Striped bass (Morone saxatilis) is the most recreationally and commercially important non-salmonid fish species in the continental United States. As such, it has been exploited to the point of collapse at various points throughout our Nation's history. The population crash of the 1980s made both fishers and fishery scientists aware of its sensitivity to overfishing and habitat degradation, joining two disparate groups in a common cause with a common goal--recovery. Fishing moratoriums, habitat restoration, and intensive stocking efforts were utilized throughout the 1980s and 1990s in order to restore the severely depleted stocks of America's favorite fish. Research conducted during this study focused on the states of Virginia, North Carolina, South Carolina, Georgia, and Florida at both the state and Federal level. Roanoke River/Albemarle Sound striped bass have been stocked throughout the United States, particularly within the study area. This population has been artificially propagated since 1879 with the number of fry and fingerlings stocked numbering in the billions. The discovery of a self-sustaining land-locked population in the Santee-Cooper Reservoir renewed interest in this game fish, spawning hatchery production in Virginia, South Carolina, Georgia, and Florida as well as other states. Like the Roanoke River/Albemarle Sound population, the Santee-Cooper population has been heavily stocked throughout the study area, creating a potential loss of genetic integrity. Our awareness of the effects of cross-stocking different strains of striped bass has grown over the last 30 years and it is necessary to determine what the historical stocking record has been so that we might better manage future stockings with an eye to restoring native strains where they have been previously depleted or extirpated. Genetic work by other researchers has been hindered due to a lack of knowledge regarding the number and strength of the strains stocked. This study is an attempt to rectify that unfortunate imbalance.

Book Striped Bass and Other Morone Culture

Download or read book Striped Bass and Other Morone Culture written by R.M. Harrell and published by Elsevier. This book was released on 1997-05-23 with total page 387 pages. 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.
