These monitoring approaches ought to hence be designed, standardized and implemented on the scale large enough to protect the mackerel life cycle.
The period of time starts in 1951 with the beginning of the good years for the Dutch fishery (>ten kt/calendar year) and ends in 1966 with the big Norwegian fishery (>500 kt/year).
