5203 |a"The main objective of the Inches Creek chum facility during 1970-1978 was to evaluate the upwelling gravel incubation technique for chum (Oncorhynchus keta) production. In particular, the effects of different egg densities, flows, and planting methods on egg-to-fry survival were tested. The mean annual production of 0.8 million chum fry represented an average egg-to-fry survival of 77%, or an 11 fold increase over the wild Inches Creek fry survival. Mean size of unfed fry was 38.1 mm and 336 mg at release. Mean size of reared 1978 brood year fry was 55.3 mm and 1.3 g. To date, the project has succeeded in tripling the annual Inches Creek chum escapement to approximately 6 - 8,000 adults since 1974. Marine survival of combined wild and hatchery fry from Inches Creek was higher than that of the wild Fraser River chum fry (0.9 - 1.8% vs 0.4 - 1.0%). In the future, all fry will be reared prior to release. Other changes include the use of surface-planting at higher egg densities instead of gravel-layer planting"--Abstract, page vi.
