This by-catch guide is designed to assist in the identification of common fish by-catch species in CCAMLR longline and trawl fisheries. The identification sheets are based on the resources provided by Australia, New Zealand, the Republic of Korea, and United Kingdom members, and the Secretariat acknowledges their contributions to this guide. Online resources have also been used for images and text description (referenced under each individual species).

It is intended to provide a useful resource for observers and in order to facilitate that outcome, users are encouraged to provide feedback through the CCAMLR Observer Scheme e-group, or thorough the Scientific Scheme Observer Coordinator email (observer [dot] scheme [at] ccamlr [dot] org). Any other resources that can be provided to improve this guide are also most welcomed.
