Journal ArticleDOI
El Niño Southern Oscillation and tuna in the western Pacific
TL;DR: This paper showed that apparent spatial shifts in the skipjack population are linked to large zonal displacements of the warm pool that occur during ENSO events, which can be used to predict (several months in advance) the region of highest skipjack abundance, within a fishing ground extending over 6,000 km along the Equator.
Journal ArticleDOI
Evidence of underestimation of European hake growth in the Bay of Biscay, and its relationship with bias in the agreed method of age estimation
TL;DR: The study highlights the need to improve biological knowledge of the species in order to improve assessment and management advice and strengthens the argument for age validation.
Journal ArticleDOI
Predicting skipjack tuna forage distributions in the equatorial Pacific using a coupled dynamical bio-geochemical model
Patrick Lehodey,Jean-Michel André,Michel Bertignac,John Hampton,Anne Stoens,Christophe E. Menkès,Laurent Mémery,Nicolas Grima +7 more
TL;DR: In this article, a simple bio-geochemical model was coupled with a general circulation model, allowing reasonable predictions of new primary production in the equatorial Pacific from mid-1992 to mid-1995.
Journal ArticleDOI

TL;DR: In this article, a global review and comparative evaluation of 35 integrated ecological-economic fisheries models (IEEFMs) applied to marine fisheries and marine ecosystem resources is presented to identify the characteristics that determine their usefulness, effectiveness and implementation.
Journal ArticleDOI
A spatial population dynamics simulation model of tropical tunas using a habitat index based on environmental parameters
TL;DR: In this paper, the authors developed a spatial, multigear, multispecies population dynamics simulation model for tropical tunas in the Pacific Ocean, based on a diffusion-advection equation in which the advective term is proportional to the gradient of a habitat index.
