 This report reviews how year class strength parameters are described and estimated in age-based stock assessments within New Zealand and overseas. The report discusses a range of assumptions commonly made with respect to year class strength parameters, including whether it is dealt with in log-space versus natural space, the choice of prior, and whether to include a penalty and/or constraining parameters to have some mean value. Recommendations for further exploration are made.
