AEBAR 2012: Non-protected bycatch
Figure 6.13: Annual estimates of fish bycatch in the orange roughy trawl fishery, calculated for
commercial species (COM), non-commercial species (OTH), QMS species, and overall for 1990–91 to
2008–09 (black points). Also shown (grey points) are earlier estimates of bycatch in each category
(excluding QMS) calculated for 1990–91 to 2004–05 (Anderson et al. 2001, Anderson 2009a). Error bars
show the 95% confidence intervals. The black line in the bottom panel shows the total annual estimated
landings of orange roughy (O. Anderson & M. Dunn (NIWA), unpublished data).
