5203 |a"Diving surveys of herring spawn were made in Lambert Channel between March 1 and 21, 1983. Spawn samples collected on transects and survey data on spawn length and width were used to estimate egg numbers. The number of eggs estimated corresponds to 4331 t of spawners in Lambert Channel in 1983. Spawn was deposited along 10.8 km of shoreline on Denman Island and 7.4 km on Hornby Island with spawn heaviest near the centre of the spawns and near the middle of the depth range. A further 79 t were estimated to have died and sunk to the bottom over the 4.8 km² area fished by gillnets. Estimates of egg loss to bird predation did not exceed 5% of total spawn"--Abstract, page iii.
