AEBAR 2012: Non-protected bycatch
Figure 6.6: Annual estimates of fish discards in the target ling longline fishery, calculated for ling (LIN),
commercial (QMS) species (COM), non-commercial (non-QMS) species (OTH), and overall (TOT) for the
years 1994–95 and 1998–99 to 2005–06 (in black). Also shown (in grey) are estimates of the ling and total
discards calculated for 1990–91 to 1997–98 by Anderson et al. (2000). Error bars show the 95%
confidence intervals.
6.3.3. Hoki/hake/ling trawl fishery
Earlier reports were limited to the hoki target fishery and only the most recent report considers
bycatch and discards for the fishery as defined by the three target species combined—but hoki is
dominant in this fishery, accounting for over 90% of the catch.
Observer coverage in the hoki, hake, and ling trawl fishery between 2000–01 and 2006–07 ranged
from 11% to 21% of the annual target fishery catch, and 78 separate vessels were observed, covering
