This paper summarizes the lessons learnt for management of small pelagic fish from case study managing international fishery on Bay Biscay anchovy. A constant catch regime ended up with a crash and closure (2005–2009) after series recruitment failures. Precautionary advices had been disregarded due to their inability predict size population during first half year when major takes place. The triggered EU develop long-term plan in 2008. In absence indicator, biological risk was minimized...
Validation of the age determination procedure using otoliths European anchovy in Bay Biscay was achieved by monitoring very strong year-classes successive spring catches and surveys, as well seasonal occurrence edge types. Historical corroboration ageing method obtained cross-correlation between groups surveys (1987–2013). Summary annual growth length is also presented. Yearly annuli consist a hyaline zone (either single or composite) wide opaque zone, disrupted occasionally some typical...

This paper describes a methodology that combines meta-population theory and stock assessment models to gain insights about spatial heterogeneity of the in an operational time frame. The was tested with stochastic simulations for different degrees connectivity between sub-populations applied two case studies, North Sea cod (Gadus morua) Northeast Atlantic sardine (Sardina pilchardus). Considering biological components population can be partitioned into discrete units, we extended this idea...
Age and size at maturation appear as key parameters governing the dynamics of a population they affect growth rate, fecundity, survival. The expression such life history traits is determined by genetic make-up modulated environmental factors mainly through phenotypic plasticity. Moreover, fishing, besides decreasing changing demographic composition can alter allelic frequencies fisheries-induced evolution selecting for some particular traits. In Bay Biscay, trend in both sardine body...
A partir de séries longues, sur plus d’un siècle production sardine les côtes françaises, l’article pose la question du comportement d’adaptation des communautés pêcheurs face aux variabilités dans l’abondance ressource. Une méthode segmentation série chronologique permet d’identifier points rupture en recherchant phases stationnaires. Le résultat aboutit à trois périodes, première débutant 1900 avec un point 1971. Les deux segments suivants courent périodes 1972 1998 et 1999 2017. mouvement...
