Abstract
Stock assessments and constant catch projections under several overcatch scenarios using the operating model developed by CCSBT SC are conducted. The main factors influencing the assessment results are (1) the period over which the longline overcatch took place and (2) assumptions about the extent to which the longline overcatch necessitates CPUE adjustments. We also consider the appropriateness of the criterion used previously by the SC to evaluate short term risk.
