Figure 2. Length-frequency distribution for Choerodon rubescens, Epinephelides armatus and Pagrus auratus sampled using either line fishing (Line) or stereo-BRUVS.

Figure 2

The separate bandwidth ‘h’ of each KDE was chosen by the Sheather & Jones (1991) bandwidth selection procedure. Length classes for the histogram of each species were chosen to match the KDE; C. rubescens 50 mm, E. armatus 40 mm and P. auratus 50 mm. Rug plot just above the x-axis indicate individual length observations. Dashed vertical lines indicate the minimum legal length of retention for each species and ‘n’, indicates the sample size.
