Download or read book Population Structure and Movement of Black Bream Acanthopagrus Butcheri in South Australian Estuaries Based on Otolith Chemistry written by Ana Judith Giraldo and published by . This book was released on 2015 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The elemental concentration of otoliths provides an opportunity to discriminate among fish living in different habitats, and to estimate population connectivity, life history variation and potential movements. Understanding temporal patterns of recruitment and connectivity of estuarine fish populations, as well as life history variation is fundamental to elucidating population dynamics and informing effective management and conservation efforts. Estuarine associated species utilise sheltered habitats for growth and feeding, but also face fluctuating environmental conditions. Estuaries may be temporally variable sinks or sources of juveniles and have fish moving to other areas. Otolith chemistry provides a tool to reconstruct origins and quantify connectivity between juvenile and adult populations, as well as investigate movements of fish throughout their life history. The overall aim of this study was to assess connectivity and partial migration within black bream (Acanthopagrus butcheri) populations in South Australia. The key objectives were to: (1) Determine spatial and temporal variation in otolith elemental signatures to assess their usefulness for determining connectivity of black bream populations; (2) Retrospectively trace subadult fish from the Fleurieu Peninsula (FP) and Kangaroo Island (KI), South Australia, to their juvenile regions to gain an understanding of movements; and (3) Determine the proportion of migrant and resident life history types within estuarine populations and if these different contingents reflect a hybrid fish genotype. I examined spatial and temporal variability in otolith chemistry of juvenile 0+ black bream to discriminate fish living in different estuaries. Fish were sampled in up to 12 estuaries on KI (7 estuaries) and the FP (5 estuaries) annually over a five year period (2007-2011). Otoliths were examined to determine if individual estuaries or groups of estuaries differed in chemical concentrations (signatures or tags), and to examine inter-annual variation in chemical tags. Tags differed among individual estuaries and in some cases adjacent estuaries shared similar chemical tags. Differences in chemical tags were detected among all estuaries in two of the year comparisons. Similarities in otolith tags were detected for five of the seven estuaries in 2010 and 2011. Grouping estuaries with similar chemical tags enhanced the classification accuracy of fish to estuaries and therefore the ability to discriminate stock structure based on otolith chemistry. Temporal differences in chemical tags were detected among years for several estuaries; however, there were no clear trends in the differences between years. The results highlight that black bream from different estuaries or groups of estuaries have unique chemical tags that can be used to trace cohorts of fish. Such differences can be used to estimate connectivity, population movements, and the function of estuaries as nursery areas for this species in subsequent years. Otolith chemistry was then used to reconstruct origins and to quantify connectivity between juvenile and adult components of black bream populations. Trace element composition of juvenile black bream otoliths from broad areas representing estuaries from each of KI and FP were quantified for each of four years (2007-2010) and used as baseline data to retrospectively trace the juvenile region of 1 to 3+ year black bream. Such an approach was possible because there were differences in otolith element concentration of young-of-year black bream among broad areas. Through LA-ICP-MS analysis of the juvenile region of subadult (1 to 3+ year old) black bream, I was able to estimate the proportion of juvenile fish that recruited from these two regions through time, as well as temporal patterns of connectivity between KI and FP. My results suggest variability among cohorts of the same age, among age classes within a cohort and between regions in terms of self-recruitment. These results highlight the variable nature of connectivity among populations and recruitment to adult populations suggesting that management and conservation efforts may need to consider such variability. Partial migration, where some members of a population migrate showing life history profiles of salinity habitats was evaluated in six estuarine populations of black bream from KI, using otolith Ba:Ca ratios. Profiles of Ba:Ca across otoliths were used to broadly determine fish habitat use (freshwater, estuarine, marine) and assign euryhaline or stenohaline status. In addition, we evaluated whether migratory fish may represent hybrid fish between black bream and yellowfin bream (Acanthopagrus australis) using an eight locus microsatellite library. Partial migration was observed in all six estuarine populations, although for most estuaries there were greater numbers of migratory fish than resident fish. Hybrid fish were found in five of the six estuaries and comprised both migratory and resident fish. Both resident and migratory fish spent most time in marine waters, but migratory fish also moved to estuarine and freshwaters. Similar patterns were also seen for hybrid fish. The data highlight the different migratory behaviours of subadult individuals and show that hybrid bream had reached estuaries previously thought to be inhabited by pure black bream. Complex migratory patterns may allow populations to persist under adverse environmental conditions and in systems subject to change. Otolith chemistry data provided greater insight into patterns of connectivity between broad geographic regions and life history variation of black bream in South Australia. The variable nature of connectivity among populations and recruitment to adult populations suggests that conservation efforts will be more complex than protecting a single region. However, the temporally variable contribution of recruits and broad scale connectivity between juvenile regions suggests that no one region acts as a single 'source' of recruits, potentially safeguarding the species against the loss of functional nursery habitats. In the same manner, the ability of black bream populations to possess a suite of movement behaviours (likely in response to different conditions) may be beneficial in a dynamic environment such as an estuary since it allows the persistence of populations when faced with increasing habitat degradation. Overall, these findings infer that the adoption of a flexible life history strategy likely enhances species resilience to fluctuating environmental conditions and potentially adverse impacts." -- abstract, leaves 8-9.

This book was released on 2009-08-07 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Techniques and theory for processing otoliths from tropical marine fish have developed only recently due to an historic misconception that these organisms could not be aged. Otoliths are the most commonly used structures from which daily, seasonal or annual records of a fish’s environmental history are inferred, and are also used as indicators of migration patterns, home range, spatial distribution, stock structure and life history events. A large proportion of projects undertaken on tropical marine organisms involve removal and processing of calcified structures such as otoliths, statoliths or vertebrae to retrieve biological, biochemical or genetic information. Current techniques and principles have evolved rapidly and are under constant modification and these differ among laboratories, and more particularly among species and within life history stages. Tropical fish otoliths: Information for assessment, management and ecology is a comprehensive description of the current status of knowledge about otoliths in the tropics. This book has contributions from leading experts in the field, encompassing a tropical perspective on daily and annual ageing in fish and invertebrates, microchemistry, interpreting otolith microstructure and using it to back-calculate life history events, and includes a treatise on the significance of validating periodicity in otoliths.

Download or read book Ecological Connectivity among Tropical Coastal Ecosystems written by Ivan Nagelkerken and published by Springer Science & Business Media. This book was released on 2009-09-23 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mangrove forests, seagrass beds, and coral reefs are circumtropical ecosystems that are highly productive, and provide many important biological functions and economic services. These ecosystems cover large surface areas in the shallow tropical coastal seascape but have suffered from serious human degradation, especially in the last few decades. Part of their diversity, productivity, and functioning seems to be based on their juxtaposition. Especially in the last decade significant advances have been made on new insights into their ecological connectivity. This authoritative book provides a first-time comprehensive review of the major ecological interactions across tropical marine ecosystems that result from the mutual exchange of nutrients, organic matter, fish, and crustaceans. A group of leading authors from around the world reviews the patterns and underlying mechanisms of important biogeochemical and biological linkages among tropical coastal ecosystems in 15 chapters. Included are chapters that review cutting-edge tools to study and quantify these linkages, the importance of such linkages for fisheries, and how tropical ecosystems should be conserved and managed for sustainable use by future generations. The book uses examples from all over the world and provides an up-to-date review of the latest published literature. This book is a ‘must read’ for professionals working on the conservation, management, and ecology of mangrove, seagrass and coral reef ecosystems.
Download or read book Freshwater Fisheries Ecology written by John F. Craig and published by John Wiley & Sons. This book was released on 2016-01-12 with total page 920 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.
