Results of the zero-inflated Poisson generalized linear mixed effects models used to examine the influence of year (3 levels: 2013/14, 2017/18 and 2019/20) and region (3 levels: North Coast, Central Coast and South Coast) on the catch per unit effort (CPUE; numbers/fisher days) estimated for line-based recreational fishing activity in the estuarine and oceanic waters of NSW during 2013/14, 2017/18 and 2019/20.

To enable examination of the influence of each predictor variable on both the count and zero-inflated components of each model, partial ɀ-tests (α = 0.01) were used to examine the null hypotheses that βi = 0 or γi = 0 for a retained parameter or interaction term (where βi and γi respectively represent the partial regression coefficients for a variable’s regressor in the count and zero-inflated components of the model). The total sample sizes (n = number of long-term Recreational Fishing Licence holders) of each model are also shown.
