Herring stock estimates from diving surveys of spawn for the north coast of British Columbia in 1982 / by J.F. Schweigert and C.W. Haegele.: Fs97-4/1795E-PDF
"Divers surveyed and sampled major 1982 herring spawns in Statistical Areas 3 to 5. Spawner biomass was estimated at 5700 tonnes, which agreed closely with prespawning echosounder estimates, but was considerably lower than the 19,500 to 29,000 tonnes estimated with population models. The low estimated spawner biomass supports the decision to close the sac-roe fishery in Chatham Sound from 1979 through 1983 and in Porcher Island from 1982 through 1983"--Abstract, page iii.
