AEBAR 2012: Non-protected bycatch
Figure 6.18: Annual estimates of bycatch in the scampi trawl fishery, for QMS species, non-QMS species,
invertebrates (INV), and overall for 1990–91 to 2009–10. Also shown (in grey) are estimates of bycatch in
each category (excluding INV) calculated for 1999–2000 to 2005–06 (Ballara & Anderson 2009). Error
bars indicate 95% confidence intervals. The straight lines show the fit of a weighted regression to annual
bycatch. In the bottom panel the solid black line shows the total annual reported landings of scampi
(Ministry of Fisheries 2011) and the dashed line shows annual effort (scaled to have mean equal to that of
total bycatch).
