    Abstract

    Haul by haul data acquired by the UK from longline fishing for Dissostichus eleginoides around South Georgia were compared with data reported to CCAMLR and held in CCAMLR's longline database (database C2). Some instances of incomplete reporting were identified, where blocks of data appear to be missing from the CCAMLR database. One instance was identified of multiple hauls being submitted as single records. A number of hauls yielding zero catches present in the data acquired by the UK have not been reported to CCAMLR. In 1996 less than 10% of the hauls showed large discrepancies between the two datasets, with many of the records for individual fields being identical. The number of discrepancies between the CCAMLR database and the data acquired by the UK declined from 1994 to 1996. However, there were a considerable number of discrepancies between the CCAMLR data and those acquired by the UK in reporting bycatch and incidental mortality of birds.
