Commercial catch-effort data and fisheries observer records of catch and discards by species were used to estimate the rate and level of non-target catch and discards in the ling longline fisheries for the fishing years 2002–03 to 2017–18. Estimates were made for broad categories of catch and discards including target species, QMS species, non-QMS fish, and non-QMS invertebrate species, and estimates of annual catch were made for several of the major individual non-target species.
