Enhancing the utility of known-biomass production models: a case study of the Bay of Biscay and Iberian Coast ecoregion
[EN] Our general purpose is to support the use of known-biomass production models (KBPMs), illustrating their usefulness by addressing the evolution of surplus production (SP) over time and the factors affecting it (e.g. environment). We also demonstrate the utility of KBPMs for multispecies managem...

Retrospective analysis revealed SP shifts in northern hake stock for reasons other than biomass variability.
