This book was released on 2017-10-17 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The American Oyster Crassostrea Virginica Gmelin The influence of other factors of the environ ment on the shape and sculpture of oyster shell has been reported by many investigators who noticed that specimens growing in calm water on flat surfaces have a tendency to acquire a round shape and to have poorly developed umbones. On soft bottom and overcrowded reefs the same species tend to form long and slender, laterally compressed bodies with hooklike umbones. Lamy (1929) observed that oysters attached to a pebble or shell and, therefore, slightly raised above the bottom, had deep lower valves, more or less radially ribbed. This type of structure, according to Lamy, offered greater resistance to dislodgment by currents or wave action.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The eastern oyster (Crassostrea virginica Gmelin 1791) has great ecological and economic importance but populations have declined, especially in Chesapeake Bay, to historically low numbers. Hatcheries strive to produce oysters with beneficial characteristics for supplementation and commercial purposes, both natural and stimulated mass spawning. Unequal contribution of parents in mass spawnings potentially can lead to high levels of inbreeding and a loss of beneficial characteristics in offspring. In this study, we determined microsatellite genotypes for parents (n^parents =24, 49, and 77 parents) and progeny (n=96 each) of three hatchery-produced families and used the data for parental assignment. We observed the presence of more than two alleles per locus for some offspring, yet because genetic analysis software only allows for a maximum of two alleles per locus, we chose the two alleles with the strongest signals. For the three parent "populations" 71% of alleles had frequencies of 0.05 and observed heterozygosities were lower than expected by an average factor of 0.27. Inbreeding within the various parent populations was similar across the three families ranging from F^IS 0.26 - 0.43. In all three families, the offspring exhibited greater levels of genetic diversity and lower inbreeding levels than the parents (F^IS 0.14-0.21), and in some cases offspring exhibited alleles that were not present in the parents. Variance in the number of offspring produced per parent was observed for all families and in general,

Available in PDF, EPUB and Kindle. Book excerpt: In 1966 Congress passed the National Sea Grant College Program Act to promote marine research, education, and extension services in institutions along the nation's ocean and Great Lakes coasts. In Maryland a Sea Grant Program -- a partnership among federal and state governments, universities, and industries -- began in 1977, and in 1982 the University of Maryland was named the nation's seventeenth Sea Grant College. The Maryland Sea Grant College focuses its efforts on the Chesapeake Bay, with emphasis on the marine concerns of fisheries, seafood technology, and environmental quality. The first comprehensive review of the biology of the eastern oyster in more than thirty years. The twenty-one chapters synthesize every aspect of oyster biology -- for instance, general anatomy, physiology, the circulatory system, reproduction, genetics, diseases -- and issues related to management and aquaculture.
