Age- or length-based methods of growth estimation. What drives the choice?

G.M. Pilling and A.S. Halls

Based upon a global comparison of over 400 fi sheries, the Principal Components Analysis (PCA) methodology was used to identify factors affecting the choice of growth estimation methods. Of the six factors examined, the growth rate (K) and asymptotic length (L8) explained most of the variations. Financial resources, i.e., Gross National product (GNP), and latitude were also important factors.
