The primary purpose of this study was to determine whether various agents (adenosine 3-thiotriphosphate [ATP gamma S], trifluoperazine [TFP], troponin I, the catalytic subunit of the cyclic adenosine 3',5'-monophosphate dependent protein kinase [C-subunit], and calmodulin [CaM]) could be used to classify skinned fiber types, and then to determine whether the proposed mechanisms for Ca2+ regulat...

Turbot larvae were challenged with eight strains of Vibrio splendidus isolated from diseased larvae, plus a ninth strain pathogenic to scallop larvae (A515; Nicolas et al. 1996). Six strains caused heavy mortality but the scallop pathogen and the other two strains did not. All the strains shared a large number of phenotypic traits, and an attempt was made to relate virulence to genotype and phe...

Understanding the impact of noise on marine fauna at the population level requires knowledge about the vulnerability of different life-stages. Here we provide the first evidence that noise exposure during larval development produces body malformations in marine invertebrates. Scallop larvae exposed to playbacks of seismic pulses showed significant developmental delays and 46% developed body abn...

Marine polysaccharides are used in a variety of applications, and the enzymes that degrade these polysaccharides are of increasing interest. The main food source of herbivorous marine mollusks is seaweed, and several polysaccharide-degrading enzymes have been extracted from mollusk digestive glands (hepatopancreases). Here, we used a comprehensive proteomic approach to examine the hepatopancrea...

This study assesses the potential of the scallop Chlamys varia as a biomonitor of metal contamination in the field. Cd, Cu, and Zn concentrations were determined in the soft tissues and organs of individuals from the French Atlantic coast sampled over a 1 year period and covering a wide range of size. All metals were selectively distributed among the different body compartments considered, and ...

We evaluated the effect of where the hole is drilled in the shell when using the ear-hanging or Nimai-ake method in scallop aquaculture. We examined its influence on growth and mortality during 8-month growth trials on the scallop Patinopecten yessoensis at Shikabe, Japan. Our Ž . observations showed: 1 no differences in growth and mortality between drilling the hole in the Ž . posterior compar...

actin (2 forms) occurred 80 times (19%) and myosin (11 forms) was found 68 times (16%). The remaining ESTs could be classified as being involved in gene/protein expression (3%), immunity (7%), metabolism (31%), protein binding (7%), or cell signaling (8%) (Fig. 1). Some identified genes (11%) could not be classified into any of these groups. The sequences of all the ESTs generated from the bay ...

—Fisheries observers have documented interactions between sea turtles in the family Cheloniidae and the Atlantic sea scallop Placopecten magellanicus fishery. Sea turtle injuries resulting from interactions with scallop dredges are being mitigated through shifts in fishing effort and modifications to fishing gear. The standard New Bedford dredge can trap objects and crush them as they pass betw...

The adverse environmental impacts of building materials can be achieved by reducing the amount cement in cementitious composites, specifically when incorporating wastes as partial replacement for Portland cement. In this work, we substitute with shell by-products while keeping useful specific properties. Scallop shells are good candidates to replace part they contain calcium and available abund...
