5203 |a"Using the results of diving surveys of spawn, we estimated the 1987 adult spawner biomass in the lower east coast of the Queen Charlotte Islands at 17,171 tonnes. Divers surveyed spawns in Poole Inlet (1906 tonnes), Alder Island (42 tonnes), Section Cove (288 tonnes), Huxley Island (4090 tonnes), Saw Reef (2606 tonnes), Sedgwick Bay (307 tonnes), Selwyn Inlet (1719 tonnes), and Conglomerate Point (617 tonnes). Twenty-four percent of this spawn was deposited on Macrocystis sp. and the remainder on understory vegetation and bottom substrate. The earliest spawn in Huston Inlet and a later small spawn in Beattie Anchorage were not surveyed by divers and were estimated from surface survey data to have been deposited by 2748 and 358 tonnes, respectively. Approximately 770 tonnes of herring spawned at eleven spawn-on-kelp pond sites and the roe seine fishery harvested 1720 tonnes. Spawn was deposited to 15 m below chart datum and the average inner and outer edge of spawns was 0.2 m and 8.8 m below chart datum. Approximately 90% of the spawn area and 75% of the eggs were below mean low water"--Abstract, page iii.
