Assessment of herring spawnings in the vicinity of Nanoose Bay, B.C. / by C.W. Haegele and R.D. Humphreys.: Fs97-4/1437E-PDF ; Fs97-4/1437
"An intensive underwater survey of two herring spawnings in and near Nanoose Bay, Strait of Georgia, was conducted during the 1976 herring spawning season. The spawnings were up to 650-m wide and eggs were deposited on a wide variety of substrates. An assessment of the spawnings by traditional techniques underestimated the area of the spawnings by 41% and 96%, mainly as a result of low width estimates of the subtidal portion of the spawn. Detailed topographic maps of spawning localities showing vegetation zones should alleviate problems associated with detecting and measuring herring spawn"--Abstract, page iii.
