O'Neill, M.F. and Faddy, M.J. (2003) Analysis of recreational fish catches – dealing with highly skewed distributions with many zeros. In: 3rd World Recreational Fishing Conference, 21-24 May 2002, Northern Territory, Australia.
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 analysed using a two component approach involving a binary (zero/non-zero catch) response and the non-zero catches. A truncated regression model was effective in analysing 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.
