Última Pattern of recruitment variability in the geographical range of the exploited northeast Atlantic fish species ArchiMer Brunel, Thomas; Boucher, Jean. It has long been argued that populations living on the edges of the species geographical range should exhibit stronger environmentally imposed variations in abundances than populations living near the centre of this range. This so-called 'Species Range Hypothesis' is tested here for the recruitment of 62 marine fish populations of the northeast Atlantic, belonging to 17 species. The pattern of increasing recruitment variability from the centre towards the edges of the species range was modelled by a quadratic linear regression between an index of interannual variability in recruitment and an index of population position in species range. The relationship between recruitment variability and exploitation rate was also investigated. A wide range of...

Ano: 2006 URL: http://archimer.ifremer.fr/doc/2006/publication-1119.pdf Un modèle empirique du recrutement pour le stock de coquilles Saint Jacques, Pecten maximus (L.) en baie de Saint-Brieuc (Manche, France) ArchiMer Fifas, Spyros; Dao, Jean-claude; Boucher, Jean. This paper proposes an empirical model for the recruitment of the scallop stock, Pecten maximus (L.), in Saint-Brieuc Bay (English Channel, France). This stock shows important fluctuations in recruitment. The use of traditional models for fish population dynamics based upon an equilibrium state were inadéquate. This model includes three independent variables: spawning biomass, effects of fishing effort on the unexploited year classes, and temperature. Correlations between these expressions of independent parameters and recruitment are systematically analysed. The choice of the final model relies on minimization of the total variance unexplained portion. Introduction of fishing pattern into the model is realized by testing fishing effort effects upon two...

III. - Plancton et micronecton de la couche photique ArchiMer Boucher, Jean; De Bovee, Francis; Thiriot, Alain. Les échantillons ont été récoltés avec des filets W.P.2 (36) et un échantillonneur rapide, tube HAI (117). La campagne s'est déroulée du 10 mai au 22 juin 1970 en Méditerranée occidentale ; les prélèvements sont plus particulièrement groupés autour des Baléares, dans le golfe de Gênes et en mer d'Alboran. L'échantillonneur, traîné à 6 noeuds, était descendu jusqu'à 200 m et remonté avec quatre paliers. Sa facilité d'utilisation, sa fidélité de mode de pêche et la quantité de plancton récoltée, en font un engin bien adapté a une étude de répartition, même en Méditerranée. L'augmentation de la quantité de micronecton pendant la nuit est très sensible (1 à 8), celle du macroplancton est plus faible (1 à 2), le mésoplancton par contre ne présente pas de...
