Parameter estimates of the von Bertalanffy growth function (VBGF) and its inverse function, based on length-at-age and age-at-length data for Tilapia rendalli (Cichlidae) and Salmo trutta (Salmonidae) were derived using a variety of "direct" and "indirect" fitting methods. The results obtained...

The case is made, based on growth curves and other data on Kuwait fishes, that the maximum length in a population does not provide a reliable approximation of asymptotic length.
