Download FAR 2016/52 Applications of a Bayesian surplus production model to New Zealand fish stocks

This report details the application of a generalised surplus production model to a range of New Zealand stocks. All stocks had an abundance index, but with varying degrees of information in the data. Estimation was achieved within a state-space Bayesian framework using Sampling-Importance-Resampling, incorporating both observation and process error, and an informative prior on the intrinsic growth rate. Results support application of this type of model for formal stock assessments.
