It seems there was something that caused low chum survival along much of the coast. Chum returns had in the past several years been pretty good, but this illustrates the challenge any of our fisheries face. DFO is unable, or unwilling, to adjust exploitation rates on these fish when the inevitable un-forecasted low return year occurs. Had fisheries, sport, commercial and FN been stopped as soon as it became apparent the runs were low, the escapement may have been adequate to propagate the runs. Now this brood year return may be permanently damaged on runs where commercial/FN harvest was allowed,
