Stock assessment for British Columbia herring in 2000 and forecasts of the potential catch in 2001 / J. Schweigert. : Fs70-1/2000-165E-PDF
This report presents stock assessments from two analytical models which have been developed explicitly for British Columbia herring: (1) a modification of the escapement model described by Schweigert and Stocker (1988); and (2) a modification of the age-structured model described by Fournier and Archibald (1982). Both models reconstruct stock abundance for the period 1951-2000 and forecast pre-spawning abundance for the 2001 season. Forecasts of upcoming run size are based on the combination of estimates of surviving repeat spawners and newly recruiting spawners whish are presented as poor, average, and good, based on historic recruitment levels.
