| France and Canada have been working closely together for numerous years under the governance of The Northwest Atlantic Fisheries Organisation (NAFO) that regulates fisheries in the Northwest Atlantic. This workshop was the first step to achieve greater agreement in the estimation of age from calcified pieces between the scientific experts from those 2 countries. The goal of this project is to realize a calibration of the estimation of ages from cod (Gadus morhua) between France and Canada in order to optimize the precision of the data supplied by those countries for stock assessment purposes. There has been in the past an internal workshop for Atlantic Canada in 1997 on ageing fish and numerous workshops for Northeast Atlantic, more precisely for the... |

| Dans le cadre du programme Reproduction de l’huître perlière Pinctada margaritifera, dont l’objectif est la maîtrise des croisements, le conditionnement en laboratoire des reproducteurs est une étape nécessaire pour espérer contrôler et synchroniser la maturation de ces reproducteurs. Les facteurs présumés qui permettront de contrôler la maturation sont d’ordre environnemental : l’alimentation et la température. Cependant avant d’espérer établir la relation entre la fonction physiologique et les facteurs qui contrôlent cette fonction, il est indispensable de mettre en œuvre une zootechnie adaptée aux besoins vitaux de façon à assurer la survie et une bonne croissance. Cette étude a pour objectif de tester la survie et la croissance des huîtres perlières... |

| This scientific report describes the sea cucumber (Cucumaria frondosa) fishery in Saint-Pierre and Miquelon (France). A synthesis of knowledge on the biology and life cycle of this species is presented, as well as a history of the fishery. Using the data collected during the SPM2017-Hal scientific survey conducted in August 2017, as well as data from the professional fishery, both in Saint-Pierre and in Canada, an assessment of the sea cucumber stock and a diagnosis of the state of this stock are carried out. Management objectives for this stock, with a view to its sustainability, are proposed. |

| In 2013, the project ‘Assessment of the renewable rate of the seawater masses in the Miquelon ‘Grand Etang’ ‘ focused essentially on (1) building a data set originating from all partners (e.g., DTAM, IGN), (2) preliminary sampling of current patterns so as to facilitate the 2014 field sampling strategy. Besides this approach, a census of aerial pictures dated from 1950, 1990 and 2005 were studied to assess the temporal trends of this geographic sector. The field work to be carried out in 2014 are: 1) Bathymetry: data acquisition in the ‘Grand Etang’ in the area presently used for mussel long lines culture to obtain a comprehensive data set, transversal profiles at the strait level at the near vicinity of the current pattern measuring station. 2) Current... |

| This study aims to assess the hydrological fluxes between the ‘Grand Etang’ of Miquelon and the oceanic part. Bathymetric surveys and Doppler current meter data acquisitions were carried out from August 14th, to November 5th, 2014 and from April 1st, to end of July 2015 to allow the following estimates : Total area (227 Ha) and characteristics volumes (total : 6,7 106 m3; oscillating 2,8 106 m3 (40 %); half-tide 5,2 106 m3) Velocity Index of channel to evaluate the average current speed at cross-section channel Fluxes, on flood and ebb tide respectively : Instantaneous flow: maxima at 94,2 et 65 m3/s mean 37.2 et 24.5 m3/s. in 2014 and maxima 85,03 et 73,62 m3/s mean 26,22 et 28,20 m3/s in 2015. Circulating fluxes by tide : maxima 1,06 and 1,09 106 m3,... |

| The Atlantic halibut stock area comprises the NAFO subdivisions 3NOPs4VWX5Zc where total international catches has increased to about 2300 tonnes in 2013 and the TAC for 2014 has been set to 2563 tonnes. The St-Pierre et Miquelon uptake of the overall quota varies between 2 to 6 % over the last 10 years. In 2014, responding to a demand for improving the scientific cooperation, by the Canada France Consultative Committee (CFCC) for 3Ps management, SPM began the monitoring of the autumn fishery by on-board observer. The objectives were to provide the stock assessment working group with information on maturity given that the fishery is fishing on a spawning ground. |

| Among seabirds, alcids are particularly sensitive to bycatch in fisheries and oil pollution, yet their distribution at sea remains scarcely known in most of their breeding areas. GPS telemetry data of fifteen individuals of alcids (5 Razorbills 6 Common Murres and 4 Puffins) were analyzed to determine their distribution during the breeding period of 2016 at Saint Pierre and Miquelon Archipelago (SPM). Two analytical methods (threshold and a switching state-space model) were used to identify behavioral modes and foraging areas. We compared foraging movements and estimated the overlap between the species. Distribution and foraging covered an area located between SPM and Newfoundland. Our results revealed that the three species headed northward of their... |

| La dynamique des masses d'eau et les flux de transit semblent favoriser un comblement et/ou des limitations de renouvellement d'eau mettant en péril la durabilité de l’environnement de cette lagune Miquelonnaise. La Préfecture de Saint Pierre et Miquelon et la DTAM, en soutien à la gestion durable de cet environnement, ont sollicité l’Ifremer pour l’évaluation des flux d’alimentation de cette lagune. Une mission sur place a été réalisée en juin 2016, pour coordonner les actions et effectuer un certain nombre de mesures préliminaires (jaugeages et bathymétrie du chenal, courantométrie horizontale). Ces données sont complétées par une acquisition continue des vitesses de courant, avec des données disponibles à ce jour du 2 juin au 15 novembre 2016.... |

| France and Canada work together to follow the salmon populations (Salmo salar) of the North-western Atlantic, integrating the French territory of Saint Pierre and Miquelon (subdivision 3Ps). Ageing data are thus provided by these countries. The age estimation of salmon is carried out starting from the scales. These present two distinct areas because this migrating fish lives at first in rivers and the second part at sea with some passages in rivers (homing phenomenon). As a result of which, the interpretation of ages from these scales is difficult. The purpose of this meeting which was held in Saint-Pierre and Miquelon from the 10 to September 14, 2012 with French and Canadian scientists, was to measure and optimize the precision of the age data provided... |

| Ce document présente un bilan des pêcheries de Saint-Pierre et Miquelon et l'état des connaissances sur les principales ressources exploitées par les navires de l'archipel. La distribution géographique de ces ressources (sédentaires dans la ZEE française, à l'échelle du 3Ps, ou plus largement distribuée) implique que les évaluations scientifiques et la gestion s'effectuent au niveau national, dans le cadre d'une collaboration franco-canadienne ou au niveau international (NAFO, ICCAT). |

| Initiated in 2013, the present work carried out in 2014 extends the monitoring network focusing on marine invasive exotic species in Saint-Pierre and Miquelon archipelago. In a global context of coastal ecosystems’ changes, accentuated by direct or indirect effects of human activities, it became essential to implement a monitoring survey and to track the expansion of marine invasive species along Saint-Pierre and Miquelon shoreline. Fukui traps and tunicates collectors deployed on different stations as well as the timely completion of observational dives, have provided the following conclusions: several invasive species were again reported within the local marine ecosystem. Those species, i.e., Carcinus maenas, Caprella mutica, Ciona intestinalis,... |

| Mytilus early development biossays have been used for sediment toxicity testing in the coastal zone heavily contaminated by the river Seine. This bioassays have been realized from fecundation to "D" larval stage in presence of sediment aqueous extracts. Results exhibit a high variability wich could not be related to any geographical gradient, probably due to a large effect on variance of seasonal variations. |
