5203 |a"From diving and surface surveys of spawn, 24,354 tonnes of herring were estimated to have spawned in the North Coast District of British Columbia in 1986. In Chatham Sound (Areas 3 and 4N) 16,835 tonnes spawned in three waves, with 97% spawning in the second wave. On north Porcher Island (Area 4S) 1939 tonnes spawned in a first wave in Hunt Inlet and 436 tonnes spawned in a second wave in Malacca Passage, for a total of 2375 tonnes. An estimated 4181 tonnes spawned on south Porcher Island (Area 5N) and 963 t in Area 5S. Estimated spawner biomass was three times greater in 1986 than in 1982, when the last diving survey was made. Spawn surveyed by divers was deposited over a narrow depth range on gradually sloped shorelines"--Abstract, page iii.
