Última Vertical distribution of brittle star larvae in two contrasting coastal embayments: implications for larval transport ArchiMer Guillam, Morgane; Bessin, Claire; Blanchet-aurigny, Aline; Cugier, Philippe; Nicolle, Amandine; Thiébaut, Éric; Comtet, Thierry. The ability of marine invertebrate larvae to control their vertical position shapes their dispersal pattern. In species characterized by large variations in population density, like many echinoderm species, larval dispersal may contribute to outbreak and die-off phenomena. A proliferation of the ophiuroid Ophiocomina nigra was observed for several years in western Brittany (France), inducing drastic changes on the benthic communities. We here studied the larval vertical distribution in this species and two co-occurring ophiuroid species, Ophiothrix fragilis and Amphiura filiformis, in two contrasting hydrodynamic environments: stratified in the bay of Douarnenez and well-mixed in the bay of Brest. Larvae were collected at 3 depths during 25 h within each...

IFREMER has encouraged for over 15 years the oceanographic modeling of sea waters all around the metropolitan French coasts in order to facilitate environmental coastal studies. In that context, the North-Western Mediterranean Sea confi guration (MENOR: 1.2 km – 60 vertical levels) has been introduced in the framework of Previmer operational forecasting system (http://www.previmer.org/en). This article gives an insight into the operational applications and scientific research using this MENOR configuration.

Anchovy (Engraulis encrasicolus) is an important commercial species and one of the most abundant pelagic fish in the Gulf of Lions and the Catalan Sea. The factors influencing its recruitment are crucial to fisheries and ecological research. Among those factors transport of larvae by hydrodynamics (currents) is important because it determines whether the organisms can reach areas favourable to recruitment or are dispersed. Therefore, the first step in anchovy recruitment modelling is to simulate North-western Mediterranean Sea circulation. Several years (2001-2008) of hydrodynamics were simulated with the MARS-3D code. The resulting simulated currents and salinity are used by Lagrangian tool, Ichthyop, to transport anchovy eggs and larvae to the Western...

Ano: 2009 URL: http://archimer.ifremer.fr/doc/2009/publication-7394.pdf Modelling larval dispersal of the king scallop (Pecten maximus) in the English Channel: examples from the bay of Saint-Brieuc and the bay of Seine ArchiMer Nicolle, Amandine; Dumas, Franck; Foveau, Aurelie; Foucher, Eric; Thiebaut, Eric. The king scallop (Pecten maximus) is one of the most important benthic species of the English Channel as it constitutes the first fishery in terms of landings in this area. To support strategies of spatial fishery management, we develop a high-resolution biophysical model to study scallop dispersal in two bays along the French coasts of the English Channel (i.e. the bay of Saint-Brieuc and the bay of Seine) and to quantify the relative roles of local hydrodynamic processes, temperature-dependent planktonic larval duration (PLD) and active swimming behaviour (SB). The two bays are chosen for three reasons: (1) the distribution of the scallop stocks in these areas is well known from annual scallop stock surveys, (2) these two bays harbour important fisheries...

Ano: 2013 URL: http://archimer.ifremer.fr/doc/00146/25705/26396.pdf Modelling larval dispersal of Pecten maximus in the English Channel: a tool for the spatial management of the stocks ArchiMer Nicolle, Amandine; Moitie, Roderic; Ogor, Julien; Dumas, Franck; Foveau, Aurelie; Foucher, Eric; Thiebaut, Eric. The great scallop Pecten maximus supports one of the most important and valuable commercial fisheries around the British Isles and in the northwest of France, but the resource is mainly managed at the scale of each local fishing ground through a combination of European, national and local measures. To analyse the larval dispersal pathways and connectivity patterns among fishing grounds of the great scallop in the Celtic Sea and the English Channel, a particle tracking model was developed. The model combined a 3D physical circulation model that simulated currents and temperature fields and a scallop larval submodel that took into account a temperature-dependent planktonic larval duration and an active vertical swimming behaviour. Due to the lack of stock... Tipo: Text Palavras-chave: Connectivity; English Channel; Fishery management; Great scallop; Larval dispersal; Particle-tracking model.
