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...

Influence des variations des facteurs environnementaux sur la croissance de poissons de l'Atlantique
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Barrios, Alexander.
The impact of biotic factors such as density-dependent processes, recruitment, total mortality, and abiotic factors such as upwelling intensity, temperature and chlorophyll a concentration on the variation of growth parameters of pelagic and demersal fish were studied during the periods 1990 - 2008 (pelagic) and 1971 - 2015 (demersal). Life history parameters vary according to the species and from one region to another and over time within a given area because of their plasticity and the high fishing pressure. Interspecies and inter-regional comparison were carried out. Non-linear mixed effects models were used on different fish species of the Atlantic Ocean in order to estimate the growth parameters at the individual and population levels. Variations in...
