A review of assessment tools for data-limited fisheries / Z.Y. Zhang. : Fs70-1/1999-194E-PDF

One of the precautionary management approaches is to set up a pair of reference points, a target reference pint (TRP) and a limit reference point (LRP). A TRP indicates the exploitation target and an LRP defines the limit, toward which management strives. TRPs and LRPs are formulated through technical analysis. This paper describes various empirical equations and fisheries assessment models which can be used to derive reference points. The emphasis was put on the data requirements and procedures for fitting models and estimating parameters. Assumptions involved in the models are described. The bootstrapping and Monte Carlo simulation techniques, and Bayesian analysis, are also illustrated.
