L'étude des moules de bouchots, Mytilus edulis L. a été réalisée pour caractériser les phénomènes biologiques et leur importance énergétique dans le bassin de Marennes-Oléron. Le suivi hydrobiologique a montré que la nourriture disponible pour les moules est plus abondante du printemps au début de l'été. Il a été possible de mettre en évidence une compétition spatiale extrêmement forte, au niveau intraspécïfique. Les moules cultivées à partir du transfert des naissains collectés sur cordes poussent plus rapidement que celles provenant d'une fixation directe du naissain sur les bouchots. La période de ponte est étalée entre février et  mai d'où l'existence de recrutement en juin. On peut proposer comme période de pêche, une saison allant de juin à novembre,...

A displacement of the fishing effort of the French pelagic trawlers from anchovy to the seabass fisheries is observed. A such situation on a non-quota managed species requires to analyse carefully the evolution in the status of seabass stocks. The evolution of fishing effort, the production and the landings per unit of effort were studied from 2000 to 2007 for the bottom trawling and for the pair pelagic trawling in the ICES sub-areas VIII and VII. The fishing effort was assessed by using a threshold on the landings by month in order to select the most effective fishing effort as representing 75 % of the effort concerned with seabass landings. Length compositions and age-length keys were used to calculate the cpue-at-age series. A total mortality value was...

Ano: 1993 URL: http://archimer.ifremer.fr/doc/00141/25189/23295.pdf Modélisation biophysique pour la prévision du recrutement ArchiMer Allain, Gwenhael. Exploited fish populations are dependent on recruitment (i.e. size of the new year class) to sustain their abundance. Recruitment variations are related to hydroclimatic variations and may accentuate the detrimental effects of fishing. Recruitment prediction requires accurate fisheries oceanographic tools, which are expected to be more reliable than large-scale correlation analyses between fish abundance and climate variables. Recruitment is the result of the integration over a season and large oceanic areas of processes affecting larval survival, which are dependent on small-scale mechanisms. Hydrodynamic models are a tool to perform this integration. This thesis aims at exploring and modelling physical-biological interaction mechanisms in order to...

In a context of climate change, understanding the response of species to changes in the environment and the implications for their geographic distribution is paramount. Species distribution models (SDM), through the formulation of relationships between the organism and its environment, provide a tool to explore species response to different types of environmental stresses. This study presents the development and a first application of a mechanistic and generic SDM, using a multi-agent modelling platform: NetLogo. The model allows to simulate the spatialized population dynamic of a bentho-pelagic species, in response to environmental variations. The model developed is an individual-based (IBM) mechanistic model, which incorporates a DEB (Dynamic Energy...

Part 1: modelling ArchiMer Ramzi, Azeddine; Arino, Ovide; Koutsikopoulos, Constantine; Boussouar, Ahmed; Lazure, Pascal. A spatio-temporal model describing the dynamics of a population of sole is presented. The model is an extension to a 2D-space structure of a 1D model published by the three first authors. Spatial migration is modelled by an advection-diffusion second order operator with constant coefficients. The physical domain is represented by a half-plane with the coast as its boundary. A formula for estimating the proportion of eggs reaching the juvenile stage, depending upon climatic, transport, growth and mortality processes, is derived. Numerical results are deferred to elsewhere.

Part 2: numerical simulations ArchiMer Ramzi, Azeddine; Arino, Ovide; Koutsikopoulos, Constantine; Boussouar, Ahmed; Lazure, Pascal. This paper is the second part of a work on the modelling of larval migration and growth fur the sole of the Bay of Biscay (Solea solea (L.)). The goal of the paper is twofold: first of all, it aims at presenting a numerical application of the formulae (concerning the recruitment rate) elaborated in the first paper. Results show a high sensitivity with respect to some parameters. Then, a comparison is made with a numerical model using a 3D circulation model provided by Ifremer.

ArchiMer De Pontual, Helene; Lagardere, Francoise; Troadec, Herve; Batel, Alain; Desaunay, Yves; Koutsikopoulos, Constantin. Sole nurseries are located in the main bays and estuaries of the Bay of Biscay, where juveniles from the same stock. concentrate and constitute temporarily isolated groups. This context being favourable for elemental analyses of juvenile otoliths this study has been initiated with the aim of obtaining environmental imprints of the main nurseries of origin of juveniles recruiting to the adult stock, and of evaluating the relative contribution of these nurseries to the stock. The objectives were to compare (i) the otolith elemental imprints obtained by sampling juveniles in the Loire and the Gironde nurseries, and (ii) two multi-element analysis techniques: laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) and solution-based ICPMS...

Since the mid-1980s, an increase in abundance of the annelid polychaete Lanice conchilega (Pallas) (Annelida: Polychacta, Terebellidae) has been observed in the Bay des Veys (western Bay of Seine). The first particularity of this population is that it is strictly limited to the eastern side of the bay, in an oyster aquaculture area. Its proliferation (over 7 000 ind.m(-2)) has had a significant impact on the local aquaculture. Several studies have been carried out since 1993; monthly monitoring of population densities and size structure has demonstrated the lack of significant juvenile recruitment between 1993 and 1996. In terms of geographical occupation, maps of population spatial distributions were drawn in 1995 and 1998. They showed an increase in...

Reproductive biology and population dynamics of Ophiura Ijungmani were studied by measuring disk diameters and by examining oocyte size-frequencies and fecundity from a sequential seasonal series of large samples from a 2900 m deep Permanent Station in the Rockall Trough (Northeast Atlantic). Egg size (max. 90 !lm) and fecundity (up to 57000 eggs per individual) suggests indirect planktotrophic development, while a clear annual cycle in gametogenesis, with probably synchronous spawning in JanuaryFebruary, confirms a marked seasonality that is also seen as an annual, summertime set of postlarvae on to the bottom.

This study is based on catched larvae data base produced since C. gigas was first imported into the Charentais Sounds (late 1960s, early 1970s). The method for catching larvae using a towed net remained unchanged between 1950 and 1998. Four sites have been sampled in the Bay since 1970, two situated in the Seudre estuary and two in the middle of the Bay. Two other sites from near the mouth of the Charente River have been sampled since 1982. For each sample, oyster larvae were counted in four size classes, from the young larva (1-4 days) to near metamorphosis (16-20 days). Each year, 100 to 150 captures were carried out at all sample sites between June and September. Captures from July and August represent 99% of the total. The main variables were: capture...

Observations on the gonads of 50 mm mussels, made during 1983 and 1984, showed that the onsert of gametogenesis occured during September and that the gonads reached maturity in December. Spawning took place from early February to April at temperatures from 10 to 12°C. The flesh had a high water content at the beginning of the spawning period. The pelagic live of the larvae lasts about 30 days with settlement occurring in June when some 90 and 100 spats settle on 1 cpm of rope per day. The intensity of recruitment was 56.10(4) and 722.10(4) larvaes on rope corresponding to a square meter during 1983, and between 28.10(4) and 81.10(4) during 1984.

In the southern Benguela, sardine and anchovy spawn on the Western Agulhas Bank. Eggs and larvae are transported to the West coast nursery ground by a! coastal current. Once the larvae reach the West coast, retention within the favorable coastal domain is key to larvae survival and recruitment. The Cape Columbine-St Helena Bay area is the main nursery ground along the West Coast. In this area, the interaction between upwelling and topography results in the formation of an upwelling plume. The plume, and the associated circulation patterns, is thought to be the mechanism providing retention within the coastal domain. The dynamics of the plume are studied using a set of:numerical experiments. It is shown that an equatorward wind forcing produces a cyclonic...
