Comment :

VB growth curve modelled using parameterization proposed by Schnute. Closure of the anchovy fishery during 2005-2010 allowed for the estimation of M from population numbers at age from successive surveys before and during the closure. Growth estimates outlier in auximetric graph? Not checked.
