In addition, a biomass dynamics stock assessment model was developed based on estimates of historical catch and CPUE. This model suggested a stock that was initially heavily fished to a low level in the 1980s, then increased rapidly during the 1990s, and has plateaued at levels well above BMSY since the mid-2000s.
