Abstract

Data from surveys of recreational anglers fishing on three estuaries in eastern Australia reveal highly skewed distributions of catches with many zeros. Such data may be analyzed using a two-component approach involving a binary (zero/non-zero catch) response and the conditionally distributed non-zero catches. A truncated negative binomial model was effective in analyzing the non-zero catches. Covariates were incorporated in the modelling, and their critical assessment has led to improved measures of fishing effort for this recreational fishery.
