A Bayesian approach for estimating length-weight relationships in fishes

A Bayesian hierarchical approach is presented for the estimation of length-weight relationships (LWR) in fishes. In particular, estimates are provided for the LWR parameters a and b in general as well as by body shape. These priors and existing LWR studies were used to derive species-specific LWR parameters. In the case of data-poor species, the analysis includes LWR studies of closely related species with the same body shape. This approach...
