    Further analyses of the GLM trends for M. paradoxus and M. capensis
    (2008) Glazer, Jean Patricia; Butterworth, Doug S; Leslie, R W
    This paper takes a closer look at CPUE analyses, particularly with a view towards determining the reason for the sharp decline in the standardized CPUE index from 2006 to 2007 for M. capensis. Results from including and excluding night-time trawls are also presented from an analysis of data covering the period 2000-2007.

    Historical background to the South African horse mackerel fishery and its management
    (2004) Johnston, Susan J; Butterworth, Doug S; Leslie, R W
    The commercial fishery for the South African horse mackerel Trachurus capensis began in 1950. Horse mackerel are exploited by four fleets: purse-seine, offshore demersal, inshore demersal, and midwater trawl. Characterisation of the catches by these sectors is complex. A brief summary will be given here, and will be described in more detail later.
