A case for under-used or vacant habitat has been made for several streams in the province during early reconnaissance in the Salmonid Enhancement Program (1975-1979). The most obvious cases (e.g. Salloomt River, Salmon River headwaters near Kelsey Bay, Chilliwack River tributaries) identified potential steelhead habitat above anadromous barriers. Others speculated that available habitat was unseeded through fish density/habitat contrasts (e.g. Coquihalla and Silverhope systems). To date, little evidence has been produced which clearly demonstrates the success or failure of juvenile steelhead stocking or juvenile stock monitoring. Recent discussion of "headwater" stocking (Hooton, memo: September 11, 1985) suggests the adult returns from mid-summer to early fall outplants of age (0+) fish continue to be "poor" on Vancouver Island. The purpose of this snorkel reconnaissance was to examine some early returns from hatchery fry stocked in the Silverhope Creek. Annual late August monitoring of fry and parr suggested consistently greater abundance of pre-smolts, following increased recruitment (natural or artificial).
