An in situ study of predator aggregations on scallop (Pecten maximus (L.)) dredge discards using a static time-lapse camera system.
The impact of demersal fishing gears on benthic habitats and species has been the subject of much attention recently, and suggestions have been made that scavenging epifaunal species may benefit at the population level from the additional food source provided by discards. This paper investigates some aspects of this process, including the relative attractiveness to predators of different discar...
متن کاملMolecular Characterization of an Endozoicomonas-Like Organism Causing Infection in the King Scallop (Pecten maximus L.)
One of the fastest growing fisheries in the UK is the king scallop (Pecten maximus L.), also currently rated as the second most valuable fishery. Mass mortality events in scallops have been reported worldwide, often with the causative agent(s) remaining uncharacterized. In May 2013 and 2014, two mass mortality events affecting king scallops were recorded in the Lyme Bay marine protected area (M...
متن کاملThe 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...
متن کاملCadmium-binding proteins in the scallop Pecten maximus.
Scallops, Pecten maximus, accumulate cadmium naturally in the digestive gland to a level of approximately 100 ppm wet weight. Of this cadmium, 60% was soluble and was composed of three weight classes as judged by Sephadex G-100 chromatography. Of the soluble cadmium, 60% was in the 55,000 molecular weight range and 20% each in an excluded fraction and a 10,000 molecular weight fraction. The 55,...
متن کاملEnvironmental Variability and Energetic Adaptability of the Great Scallop, Pecten Maximus, Facing Climate Change Environmental Variability and Energetic Adaptability of the Great Scallop, Pecten Maximus, Facing Climate Change
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 ...
