Page "Sustainable fishery" Paragraph 9

* Long term constant yield is the idea that undisturbed nature establishes a steady state that changes little over time.

Properly done, fishing at up to maximum sustainable yield allows nature to adjust to a new steady state, without compromising future harvests.

However, this view is naive, because constancy is not an attribute of marine ecosystems, which dooms this approach.

Stock abundance fluctuates naturally, changing the potential yield over short and long term periods.
