The quality of great scallop (Pecten maximus) sperm after thawing.
Most publications devoted to the cryopreservation of mollusc sperm have focused on the definition of technical protocols, avoiding the description of sperm quality after thawing. The present study investigated the effects of cryopreservation on sperm quality in the great scallop. Wild scallop were fished during the natural spawning period and conditioned in the hatchery before use. Sperm sample...

We developed a full life-cycle bioenergetic model for the great scallop P. maximus relying on the concepts of the Dynamic Energy Budget (DEB) theory. The covariation method was implemented to estimate the parameters of a standard deb model. Such models are able to predict various metabolic processes from a food availability marker and temperature in the environment. However, suspension-feeders ...

Structure and function of octopine dehydrogenase of Pecten maximus (great scallop).
This enzymic reaction was discovered in 1959 in some marine invertebrates (Thoai & Robin, 1959). ODH was first isolated from Pecfen maximus (Thoai ef al., 1969). Since then this enzyme has been purified from other invertebrates (Gade, 1980). In molluscs capable of rapid locomotion, or short-term bursts of muscular activity, ODH performs a function similar to that of lactate dehydrogenase in ver...
متن کاملVariation in Size and Growth of the Great Scallop Pecten maximus along a Latitudinal Gradient
Understanding the relationship between growth and temperature will aid in the evaluation of thermal stress and threats to ectotherms in the context of anticipated climate changes. Most Pecten maximus scallops living at high latitudes in the northern hemisphere have a larger maximum body size than individuals further south, a common pattern among many ectotherms. We investigated differences in d...
