IMPACT OF CLIMATE CHANGE ON ANCHOVY AND SARDINE POPULATIONS OF THE
NORTH-EAST ATLANTIC: A DEB-IBM MODELLING APPROACH.
The objective is the evaluation of the impact of climate change at the
horizon 2100 on the populations of anchovy and sardine in the Bay of
Biscay. This study will rely on mechanistic modelling at population
scale based on an Individual-Based Modelling (IBM) approach and on the
Dynamic Energy Budget (DEB) theory. Growth and reproduction will be
represented at the individual level throughout the life cycle, and
included in a population model to analyze the recruitment process, which
is key in the dynamics of these populations. This study is part of the
European H2020 CERES project. The environmental forcing will be
extracted from the coupled model POLCOMS-ERSEM from the project partner
Plymouth Marine Laboratory and will cover the period 1960-2099 under
different climate change IPCC scenarios. A first step will focus on
model calibration, especially the natural mortality parameters, on a
hindcast period impacted by fishery, as well as on validation using
abundance information. A second step will concern the analysis of the
specific response to climate change in the Bay of Biscay. Finally it is
suggested to consider other European regions of the current area of
distribution and investigate the regional trend of expansion or
retraction for the populations of both species.
