Fish by-catch in the krill fishery: 2018 update

Data on fish bycatch in the krill fishery from commercial catch data (120 949 hauls) and CCAMLR SISO data (17 455 hauls) up to 20 Sept 2018 was used to examine the frequency of occurrence, length-frequency distribution and geographic provenance of the key fish taxa reported. There is an increase in the data quality from the observer scheme and an increase in the frequency of fish bycatch in the commercial krill fishery catch data. As in previous years there was a high degree of overlap in the most frequently reported taxa in the C1 data and SISO data, with Lepidonothen larseni the most frequently reported in both datasets. The length-frequency distribution of all taxa for which >200 fish were measured had modal size class of <10 cm.
