This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Atlantic blue crab, Callinectes sapidus, supports the one of the largest fisheries in the United States. Despite the ecological and economic value of this species to South Carolina, many aspects of blue crab life history, which are important for ensuring effective management strategies, remain unexamined. Size restrictions for harvesting blue crabs were set nearly a century ago; however, size shifts in response to temperature can occur over contemporary timescales, and in the absence of direct climate studies, projected morphological responses to climate warming are typically based on latitudinal clines. Evidence of spatial and temporal variability for this species in both Atlantic and Gulf coast populations highlights the need for characterizing patterns of mature female blue crab demographics in South Carolina. This study incorporated a range of estuarine and marine environments from lower saline habitats and coastal spawning grounds to investigate spatial and temporal variation in female blue crab size. Long-term datasets were analyzed from 40 years (1979-2018) of fishery-independent estuarine trawl surveys and 30 years (1989 – 2018) of fishery-independent coastal trawl surveys conducted by the South Carolina Department of Natural Resources. Mixed-effects modelling procedures revealed significant spatial variability in mature female blue crab size in the southeastern U.S. Patterns in temporal trends across the time series were variable. These results provide detailed information on regional variability in female blue crab size, a life history trait that is central to effective management strategies for this species, and the applicability of latitudinal clines as a proxy for climate-induced changes in the size.

Book excerpt: This is a species profile on the blue crab. Species profiles are literature summaries of the taxonomy, morphology, distribution, life history, habitats, and environmental requirements of coastal species of fishes and aquatic invertebrates. The blue crab occurs in lower reaches of freshwater rivers, estuaries, and coastal waters along the Atlantic seaboard and Gulf of Mexico.

Available in PDF, EPUB and Kindle. Book excerpt: The blue crab (Callinectes sapidus) is an ecologically important estuarine predator and represents North Carolina's most important commercial fishery. Recent fishery-dependent and --independent data suggest the population is declining. The goal of this study was to increase our understanding of the status and population dynamics of the blue crab in NC by addressing the following objectives: (1) estimate population demographics of blue crabs in salt marsh creeks, (2) construct a discontinuous model of blue crab growth in NC using growth rates estimated from free-ranging blue crabs, and (3) provide a comprehensive stock assessment for the blue crab in NC. A series of complimentary laboratory and field studies assessed the nursery role of salt marsh habitats for the blue crab (Callinectes sapidus). Population demographics and movement patterns of juvenile and adult blue crabs were quantified in two tidal salt marsh creeks near Beaufort, North Carolina, USA during June -- October 2001. While there are many studies that report estimates of population density, mortality rates, or movement rates for blue crabs, this study represents one of the first attempts to estimate all quantities concurrently. Juvenile crabs were mobile within the interstices of the vegetated marsh surface during flood tide, and were equally distributed buried in intertidal marsh and adjacent mud areas during ebb tide. Juvenile crabs may experience a spatial refuge from cannibalism in the marsh surface since adult conspecifics are physically impeded by dense vegetation and rarely move far into marsh habitats. This spatial refuge in the vegetated marsh surface may be significant, since cannibalism represents a large source of mortality for this species. The relatively high use of the marsh surface by juvenile blue crabs, combined with a general lack of sampling these complex habitats, suggest that crab densities may be even higher in salt marsh systems than previously thought.

Available in PDF, EPUB and Kindle. Book excerpt: The Biology of Crustacea, Volume 10: Economic Aspects: Fisheries and Culture focuses on economic aspects of elements of crustacean biology associated primarily with the production of human food, namely, fisheries and culture. Organized into five chapters, this book deals first with the groups comprising the commercially important shrimps and prawns and their near relatives, as well as the generally used fishing method. It then describes the role and impact of body form in the biology and especially the fisheries of crabs. Subsequent chapter centers on lobsters and their kin, particularly the impact on fisheries methods and management approaches of behavioral responses to environment, modes of reproduction, recruitment, and population dynamics. Culture methods and factors important in managing systems through water quality control are then reported. Lastly, large-scale culture of major decapod groups, including the general biological characteristics of decapods relevant to aquaculture, is presented. This book will help stimulate the further exploration of some of the most fascinating and exciting problems in applied crustacean biology.
