A time-invariant length-weight relationship, calculated from commercial data collected between 1990 and 1996, has been used during past anchovy assessments. These same data, together with length-weight data collected during the May recruit and November hydroacoustic surveys between 2006 and 2014, are re-analysed with alternative time-dependent length-weight relationships being considered.
