Development of culture techniques for new bivalve species ArchiMer
Bodoy, Alain; Mercer, J. P..
Were are two main reasons for the development of cultivation techniques of new bivalve species. First, the risk exists that traditionally reared species may be ereadicated or severely depleted by pathogenic agents. For example the Portuguese 0yster Crassostrea angulata. disapeared from the French coasts in the early 1970's and worldwide production of the flat oyster, Oslrea edulis has been dramatically reduced by the effects of Bonamia. Secondly, in some countries production may he self-Iimiting by the size and availabilily of national and international markets and a wider species range could offer some promising new economic opportunities for aquaculturists. In particular this applies to species where there are identifiable market shortfalls.

Effect of reproduction on escape responses, metabolic rates and muscle mitochondrial properties in the scallop Placopecten magellanicus ArchiMer
Kraffe, E; Tremblay, R; Belvin, S; Le Coz, Jean-rene; Marty, Y; Guderley, H.
In scallops, gametogenesis and spawning can diminish the metabolic capacities of the adductor muscle and reduce escape response performance. To evaluate potential mechanisms underlying this compromise between reproductive investment and escape response, we examined the impact of reproductive stage (pre-spawned, spawned and reproductive quiescent) of the giant scallop, Placopecten magellanicus, on behavioural (i.e., escape responses), physiological (i.e., standard metabolic rates and metabolic rates after complete fatigue) and mitochondrial capacities (i.e., oxidative rates) and composition. Escape responses changed markedly with reproductive investment, with spawned scallops making fewer claps and having shorter responses than pre-spawned or...

Evaluation des stocks de pétoncle d’Islande Chlamys islandica, peigne du Canada Placopecten magellanicus et concombre de mer Cucumaria frondosa du gisement du banc de Saint-Pierre (subdivision 3Ps de l’OPANO). Résultats de la campagne de prospection SPM2017-Hal (14 au 24 août 2017). ArchiMer
Foucher, Eric.
The CORE 3Ps scallop stocks (Icelandic scallop Chlamys islandica and Giant scallop Placopecten magellanicus) and Sea cucumber (Cucumaria frondosa) stock were assessed in August 2017 in French-Canadian waters southwest of the Saint-Pierre and Miquelon archipelago on the one hand, and in the southern part of the French EEZ known as “Corridor” on the other. For this purpose, a scientific survey, based on a stratified random sampling plan in the CORE area and systematic sampling plan in the French Corridor was conducted onboard S/V Antéa, research vessel of the French Oceanographic Fleet. Although difficult weather conditions affected the survey, 80 sampling points were completed. The analysis of these data shows a slight decrease in the exploitable biomass of...

Force production during escape responses: sequential recruitment of the phasic and tonic portions of the adductor muscle in juvenile sea scallop, Placopecten Magellanicus (gmelin) ArchiMer
Fleury, Pierre-gildas; Janssoone, Xavier; Nadeau, Madeleine; Guderley, Helga.
Giant scallops, Placopecten magellanicus, respond to the presence of starfish predators with an escape response consisting of a series of rapid valve adductions that allow the scallop to jump or swim away from the predator. To evaluate the coordination of the activity of the tonic and phasic muscles during such escape responses, we recorded their force production by attaching a force gauge to the shell of intact scallops and then stimulating the scallops with starfish. These recordings showed series of phasic contractions (claps) separated by prolonged tonic contractions. Numerous characteristics could be quantified from these recordings including the maximal force, mean force during the first minute, force, frequency and number of claps per series, as...

Monitoring of sea scallops Placopecten magellanicus in bottom seeding trials using video in Miquelon bay, Saint Pierre et Miquelon, France ArchiMer
Robert, Stephane; Le Moine, Olivier; Lunven, Michel; Caisey, Xavier; Gaffet, Jean-dominique; Le Gall, Erwan; Vasquez, Mickael; Rodriguez, Julien; Detcheverry, Sebastien; Goulletquer, Philippe.
Placopecten magellanicus production in Saint Pierre et Miquelon (NW North Atlantic) has been developed through direct seeding of juveniles on leased areas. However, most of the culture occurs in deep water ranging from 30 to 70 meters, which requires a monitoring by video to facilitate the grow-out and survival evaluation. In August 2008, a submersible leaded structure was connected by a video cable to the surface and observation screen was defined through the video, an altimeter and two lasers. The pictures were recorded on board on hard drive and digital video recorder DVCAM, and data were georeferenced by VIDEONAV software. Analysing the video tapes allows to establish a thematic database on the ground structure, presence or absence of seeded and wild...
