    A Generalized Linear Model applied to the South Cost rock lobster CPUE data to obtain area-specific indices of abundance
    (2008) Glazer, Jean Patricia; Butterworth, Doug S
    Area-disaggregated assessments for South Coast rock lobster are currently being developed. An important input to these assessments is the catch per unit effort (CPUE) data. A Generalized Linear Model (GLM) has been applied to the data to obtain areaspecific standardized indices of abundance for input to the assessment models.

    A re-analysis of the squid jig CPUE data
    (2006) Glazer, Jean Patricia; Butterworth, Doug S
    The catch per unit effort (CPUE) indices from the squid jig fishery have to date been expressed in terms of catch per man-hour (Roel, 1998). Industry has for many years questioned the use of man-hours as the unit of effort since it is alleged that the information contained in the database regarding the number of hours fished is unreliable. A re-analysis of the jig catch and effort data has therefore been undertaken, with the unit of effort revised to one of man-days, under the assumption (though see further discussion below) that the proportion of a day spent fishing has remained roughly unchanged over time.
