Description:Relative to last year’s assessment, we made the following substantive changes in the current assessment. Changes in the input data: New data included in the assessment model were relative abundance and length data from the 2016 longline survey, relative abundance and length data from the 2015 longline fishery, length data from the 2015 trawl fisheries, age data from the 2015 longline survey and 2015 fixed gear fishery, updated catch for 2015, and projected 2016 - 2018 catches. In addition to these usual new data updates, the following substantive new changes were made to the data inputs: 1) New analytical variance calculations for the domestic longline survey abundance index 2) New area sizes for the domestic longline survey abundance index 3) Domestic longline survey estimates corrected for sperm whale depredation 4) Estimates of killer and sperm whale depredation in the fishery
