| Abstract: | Blue whiting Micromesistius poutassou mean total length at age in the north‐east Atlantic Ocean was found to vary by around ±6% during the period 2004–2011 and mean mass at age by ±22% during the years 1981–2013. Linear modelling provided strong evidence that these phenotypic growth variations can be explained by trophic conditions, mainly negative density dependence and also food availability, and a negative long‐term temperature effect on asymptotic size. |
