This book was released on 2019 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change projections estimate a 2-3°C increase in water temperatures by the end of the century. The amount of habitat with suitable temperature and oxygen concentration for aquatic organisms will also be reduced. Striped bass (Morone saxatilis) inhabiting the rivers in Southeastern Georgia make an interesting study system as they do not participate in summer coastal migrations typical of their northern conspecifics. Instead, fish in this southern population remain in freshwater environments that experience warming and decreases in dissolved oxygen. The present study aims to determine the thermal and low oxygen tolerance of juvenile striped bass collected from southeast Georgia through the measurement of aerobic metabolic scope (AMS), loss of equilibrium (LOEcrit), and critical oxygen tension (Pcrit). Fish were acclimated to one of four experimental temperatures (20, 25, 30, and 33°C), representing the range of temperatures typical of the natural environment in the summer as well as the anticipated increase in temperature due to climate change (33°C). Additionally, plasma samples were analyzed for lactate levels to assess the metabolic state of the fish. Results indicate fish acclimated to 30 and 33°C have reduced performance (lower AMS) and low oxygen tolerance (LOEcrit). The findings of this study determined that southern striped bass are susceptible to projected increases in temperature where an increase of 3°C will push them close to the thermal lethal limit and lower their ability to survive in hypoxic environments.

Book excerpt: Experiments were conducted to determine the effect of abrupt temperature and salinity changes on adult and juvenile striped bass (Roccus saxatilis) and American shad (Alosa sapidissima). Transfers were made at specific temperature and salinity differences over the range 45° to 80° F. and 0 to 35°/00. Adult and juvenile striped bass were tolerant to transfers between salt and fresh water at most temperature differences. Adult shad were tolerant to transfers from fresh to salt water and displayed some tolerance to transfers from salt to fresh water at limited temperature differences. Juvenile shad survived salinity and temperature differences from salt to fresh water, but did not survive these differences from fresh to salt water.

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: 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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this project was to provide insights about the short- and long-term patterns of habitat selection of Gulf-strain Striped Bass, Morone saxatilis, based on spatially and seasonally variable abiotic environmental characteristics (water temperature, dissolved oxygen (DO), salinity, specific conductivity, and pH) in the Biloxi River, MS system. Juvenile hatchery-reared and feral adult Gulf-strain Striped Bass were acoustically-tagged and continuously monitored via active and passive telemetry from November 2012 -- June 2014. Each month the available abiotic environmental characteristics of 40 random locations within the Biloxi River, along with sub-habitat conditions occupied by acoustically-tagged Gulf-strain Striped Bass, were sampled vertically at 1 m intervals from the surface to the bottom of the water column. Abiotic sub-habitats selected by juvenile and adult Gulf-strain Striped Bass were identified and compared to random mean abiotic conditions available in the river. During the acclimatization period to the Biloxi River, juvenile hatchery-reared Gulf-strain Striped Bass initially remained near the stocking site in sub-habitats that provided deeper depths, warmer temperatures, and higher salinity compared to other habitats within the river. Initial sub-habitat abiotic conditions may have facilitated recovery from stressors and disorientation associated with stocking. Two weeks following the stocking event, juveniles dispersed away from the release site and occupied sub-habitats with abiotic environmental characteristics that resembled background conditions of the Biloxi River. As acoustically-tagged Gulf-strain Striped Bass grew and acclimatized to the Biloxi River over the 20 month study period, seasonal patterns of habitat selection were apparent. During the fall, winter, and spring seasons, variable DO concentration and water temperatures at depth strongly influenced sub-habitat selection of both juvenile and adult Gulf-strain Striped Bass. In fall and winter, juveniles and adults were consistently located in warmer water temperatures and deeper habitats; whereas, in spring, Gulf-strain Striped Bass selected deep areas with DO > 7 mg/L. During summer, however, differences between Gulf-strain Striped Bass sub-habitats and background conditions of the Biloxi River were not clear. Although juveniles and adults were located in deep areas of the upper and lower regions of the Biloxi River, all other measured abiotic variables resembled the mean river abiotic condition characterized by DO concentrations greater than 5 mg/L and water temperatures of about 27.5°C. Ontogenetic trends in preferred habitat were evident during fall and winter when juvenile and adult sub-habitat selection was influenced by spatially-heterogeneous and vertical gradients of increased salinity at depth along the river continuum. Also, seasonal and annual variability in discharge greatly affected the decay of abiotic gradients spatially and vertically throughout the Biloxi River. Overall, the continual flux in abiotic environmental characteristics of a lotic system resulted in seasonally variable dispersal and habitat selection patterns for hatchery-reared juveniles and feral adults Gulf-strain Striped Bass in the Biloxi River. --Page ii.

Hypoxic zones in the Chesapeake Bay may pose a threat to the striped bass (Morone saxatilis) population. Hypoxia tolerance can be extremely variable among individual fish of similar size. How well an individual copes with hypoxia is determined by many factors. The purpose of this study is to investigate two factors thought to influence intraspecific variation in hypoxia tolerance: (1) locomotion and (2) social status. Individual striped bass were exposed to hypoxia individually and in groups. When exposed individually they were tested in both static flow (
