Addressing the dichotomy of fishing and climate in fishery management with the FishClim model.

ABSTRACT: The relative influence of fishing and Climate-Induced Environmental Change (CIEC) on long-term fluctuations in exploited fish stocks has been controversial^1-3 because separating their contributions is difficult for two reasons. Firstly, there is in general, no estimation of CIEC for a pre-fishing period and secondly, the assessment of the effects of fishing on stocks has taken place at the same time as CIEC⁴. Here, we describe a new model we have called FishClim that we apply to North Sea cod from 1963 to 2019 to estimate how fishing and CIEC interact and how they both may affect stocks in the future (2020-2100) using CMIP6 scenarios⁵. The FishClim model shows that both fishing and CIEC are intertwined and can either act synergistically (e.g. the 2000-2007
