Broodstock management of Crassostrea gigas

Aquaculture, 1980
Abstract The results of time-course conditioning trials indicate that there is an optimum conditioning interval during which the proportion of viable gametes is at a maximum. When matings are accomplished before or after this optimum interval, reduced gamete viability results.

108mAg and110mAg in Crassostrea gigas

Journal of Radioanalytical and Nuclear Chemistry Articles, 1992
Accumulation of radiosilver108mAg and110mAg in oysters (Crassostrea gigas) and their behavior in marine environments has been studied in the northeast Pacific coast in Japan. Enrichment of radiosilver in oysters depends on topographical conditions; significant bioaccumulation occurred in open bays, while it was hardly observed in bays with narrow ...

Antihypertensive activity of polysaccharide from Crassostrea gigas

International Journal of Biological Macromolecules, 2016
Water-soluble polysaccharide was extracted from Crassostrea gigas by hydrolysis with flavourzyme and filtered, ultrafiltered and precipitated using absolute ethanol. Sugar composition analysis performed on the C. gigas polysaccharide (CGP) by high performance liquid chromatography indicated that it was comprised primarily of glucose, and its molecular ...

A cDNA Microarray for Crassostrea virginica and C. gigas

Marine Biotechnology, 2007
The eastern oyster, Crassostrea virginica, and the Pacific oyster, C. gigas, are species of global economic significance as well as important components of estuarine ecosystems and models for genetic and environmental studies. To enhance the molecular tools available for oyster research, an international group of collaborators has constructed a 27,496 ...

Bindin genes of the Pacific oyster Crassostrea gigas

Gene, 2008
When Crassostrea gigas oyster sperm acrosome react a ring of bindin protein is exposed that bonds the sperm to the egg vitelline envelope. The putative functional unit of bindin is a fucose lectin (F-lectin) domain that is structurally conserved among phyla. There is only one bindin gene in C.

NUCLEOTIDES OF THE PACIFIC OYSTER CRASSOSTREA GIGAS (THUNBERG)

Canadian Journal of Biochemistry, 1964
The nucleotides of the Pacific oyster Crassostrea gigas (Thunberg) have been fractionated by chromatography on diethylaminoethyl cellulose and characterized by their ultraviolet absorption and paper chromatographic properties. Major components were adenosine-5′ phosphate, adenosine-5′ diphosphate, and adenosine-5′ triphosphate.

Xenobiotic biotransformation in the pacific oyster (Crassostrea gigas)

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1989
1. Oyster visceral mass and gill tissues possessed measurable flavin-containing monooxygenase (FMO) activity. 2. FMO activity was confirmed in visceral mass microsomes by oxygen uptake experiments utilizing various nitrogen and sulfur-containing chemicals along with measurement of N,N-dimethylaniline (DMA) N-oxidase and methimazole oxidation activities.

The granulocytes are the main immunocompetent hemocytes in Crassostrea gigas

Developmental & Comparative Immunology, 2017
Hemocytes comprise diverse cell types with morphological and functional heterogeneity and play indispensable roles in immunological homeostasis of invertebrates. The morphological classification of different hemocytes in mollusk has been studied since the 1970's, yet the involvement of the different sub-populations in immune functions is far from clear.

Avoiding polyspermy in oyster (Crassostrea gigas)

Aquaculture, 1988
Abstract Polyspermy was assayed by counting sperm pronuclei in orcein-stained eggs of Crassostrea gigas with ordinary light microscopy. When oocytes were inseminated within 15 min of their mechanical removal from the ovary, they became highly polyspermic, for example, 54% polyspermy with external sperm oocyte ratios as low as 30.

Detection of hepatitis A virus (HAV) in oysters (Crassostrea gigas)

Water Research, 2006
Because shellfish (oysters, clams, and mussels) are filter-feeders, pathogens become concentrated within them, and human consumption of raw, or under-cooked shellfish can result in disease outbreaks. Identification of hepatitis A virus (HAV) in shellfish has been difficult for several reasons: the concentration of virions in shellfish tissues are very ...
