Ocean triads and radical interdecadal variation: bane and boon to scientific fisheries management

摘要: Recent large-amplitude interdecadal-scale population variations in some of the world’s largest fishery stocks have exhibited a remarkable degree global synchrony. This leads to several conclusions: (1) on these scales, individual regional fish communities are not driven entirely by their own autonomous dynamics; (2) biological linkages must therefore be quite simple; (3) problem radical interdecadal stock variability would consequently appear eminently solvable. A ‘fundamental triad’ enrichment, concentration and retention processes, augments trophic energy supporting processes with mechanical earth’s ocean—atmosphere system. Examples such triad configurations coastal upwelling regions may help scientific understanding crucial fisheries issues. The idea that experimental adaptive management could proceed effectively without well-founded system accounting for natural environmental is challenged.
