Pacific Sardine ( Sardinops sagax ) in the Northeast Pacific Ocean are aged for stock assessments assuming the formation of two otolith growth bands (one opaque and one translucent) a year, but the periodicity of band formation has not been fully validated. To validate our ageing method, we investig...
