Caractérisation biologique et variation des captures de la grande alose (Alosa alosa) par unité d'effort sur le fleuve Adour (Pyrénées Atlantiques, France)

The study of logbooks from commercial fishermen on the Adour River and commercial samples allowed characterization of the allis shad population (Alosa alosa L.) caught during the period 1988-91. A better knowledge of the influence of hydroclimatic factors (rate of river flow and intensity of tidal coefficient) on the catchability of the species in that never was also obtained. Allis shad are mainly recruited to this fishery from the beginning of April to the end of May: between 78 and 89 % depending on year. Males in the population were on average younger than females. However, at the same age, males were significantly smaller in size and in weight than females. These results reinforce the knowledge already obtained on French stocks in the Loire and...

Modèles loglinéaires pour l'étude des associations entre captures par unité d'effort et variables hydroclimatiques
Provedor de dados: 5
Autores: Badia, Jacques; Prouzet, Patrick.
In this paper we study associations between categorical variables. We present an approach based on loglinear modelling. A better knowledge of the influence of the intensity of tidal coefficient (cm) and of the rate of river flow (df) on catch per unit effort (cpue) of allis shad (Alosa alosa) was obtained. Analysis performed indicated that an increase of catch per unit effort is proportionally associated with the increase in the tidal coefficient. We also noted the influence of the rate of flow.
