Those estimates provided the basis for conclusions as to whether the estimated fishing mortalities in the fishery coincided with, or were above or below, the reference levels.
This raised the additional complication of deciding what is the same and what is different, a problem that does not lend itself to statistical analysis.
Thus, an arbitrary criterion was adopted that estimated values (averaged for 10 year study periods before and after
jurisdiction) which lay within 15% of the reference level were considered to be at that level.
The 10 year study periods chosen were 1967–76, representing the international commission years, and 1979–88, representing the post-extension of jurisdiction years.
