Book Description
Based on an analysis of remains recovered from middens excavated at Mesolithic sites in Denmark, Milner's thesis aims to provide a methodology for identifying the seasonality of the European oyster. This in turn increases our understanding of the subsistence patterns of European hunter-gatherers.

Book Description
This is the first book to provide a detailed treatment of the field of larval ecology. The 13 chapters use state-of-the-art reviews and critiques of nearly all of the major topics in this diverse and rapidly growing field. Topics include: patterns of larval diversity, reproductive energetics, spawning ecology, life history theory, larval feeding and nutrition, larval mortality, behavior and locomotion, larval transport, dispersal, population genetics, recruitment dynamics and larval evolution. Written by the leading new scientists in the field, chapters define the current state of larval ecology and outline the important questions for future research.

Book Description
Nonnative Oysters in the Chesapeake Bay discusses the proposed plan to offset the dramatic decline in the bay's native oysters by introducing disease-resistant reproductive Suminoe oysters from Asia. It suggests this move should be delayed until more is known about the environmental risks, even though carefully regulated cultivation of sterile Asian oysters in contained areas could help the local industry and researchers. It is also noted that even though these oysters eat the excess algae caused by pollution, it could take decades before there are enough of them to improve water quality.

Book Description
This report presents results from research on European oyster breeding, funded under the Aquaculture Collaborative Research & Development Program (ACRDP). Four individual projects are reviewed: evaluation of genetic variability in Nova Scotia broodstock oysters in comparison with samples of naturalized populations from Maine; mass spawning of oysters from Cape Sable, Nova Scotia, in order to understand the individual reproductive success of the European oyster and its impact on genetic diversity; controlled mass spawning in tanks and assessment of the impact of heterosis on performance with four cross-bred stocks & control lines; and controlled matings in brood housing units for studying hermaphrodism and its impact on production & genetic diversity.

Book Description
This volume brings together, for the first time, a wide range of up-to-the-minute and traditional techniques and approaches to the study of genetics of organisms living in freshwater or marine habitats. Carefully edited chapters are headed by broad review articles against which are set a number of more specific experience papers which demonstrate the breadth and range of approaches currently being undertaken.

Book Description
Fish resources in natural water bodies are tending to decrease due to intensified fishing, the extensive construction of hydropower plants on rivers, and the pollution of seas and freshwater basins by indus trial and agricultural wastes. Nowadays only artificial fish rearing can meet man's requirements in fish products. Fish breeding is still very young as compared to plant breeding and animal husbandry. Although fishes have been reared artificially since ancient times in certain Asian countries, this usually included the cultivation of embryos and larvae caught in rivers and lakes. Among the exceptions, only the common carp Cyprinus carpio and the domesticated variety of the crucian carp, the goldfish Carassius auratus, which were cultivated in the East, may be mentioned. Com mon carp breeding began in China about 2000 years ago but was la ter banned by one of the emperors and started again only relatively recently. The goldfish has been cultivated for decorative purposes for about 1000 years. Many remarkable varieties of the goldfish have been developed in China and later in Japan. The first improved breeds (German "races") of the common carp known in Europe appeared after the domestication of the Da nube wild carp in the seventeenth and eighteenth centuries. Local breeds of the carp were probably established somewhat later in Chi na, Japan and Indonesia; even now these breeds have only minor differences as compared to their ancestor, the Asian wild carp.
