chum salmon. The spawning channels also provide rearing habitat for other species such <br />as Chinook and coho salmon. <br />In the late 1970s, SEP, in its infancy, developed facility targets in a piecemeal fashion. <br />The present system evolved by dividing the geographic regions into management units. <br />Each unit reviewed the individual stocks as to the status, ability to manage and capacity <br />for additional production potential. There are three area planning committees that <br />develop recommendations, the South Coast Division, Fraser River -Yukon Division, and <br />the North Coast Division. When a project shows promise, the management unit outlines <br />the expected economic and social benefits and submits it to the Treasury Board. For <br />allocation of construction and operating dollars, the project has a goal of 1.5:1 <br />benefit/cost ratio (Hurst and Blackman 1988). Each project uses estimated survival rates <br />for each type of enhancement strategy and is sized accordingly. <br />Federal fisheries biologists have increased productivity of lakes and streams by the <br />application of fertilizers. This technique is used in situations when there are sufficient <br />sockeye salmon spawners and suitable habitat is available. The fertilization promotes <br />increased growth of the basic components. of the salmonid food chain. SEP also <br />concentrates on habitat improvements for enhancing salmonid productivity by some basic <br />stream improvements. These improvements may require physical cleanup, placement of <br />boulders, planting of streamside vegetation, flow control, and eliminate possible pollution <br />sources. <br />We reviewed 18 projects in BC; 9 were considered true supplementation, 8 were <br />evaluated. One of these projects was considered not successful in contributing to natural <br />production. <br />Steelhead <br />BC's total Steelhead hatchery production for 1989 was only 2.4 million fish. These were <br />planted into 28 systems. Steelhead are released at three life history stages: smolt, parr, <br />and fry. The strategy of the smolt programs is to grow the. smolts as large as .possible <br />(60-100 g or 190-220 mm), then outplant during late April to late May. The smolt-to- <br />adult survival varied from 1 percent for small smolts to almost 10 percent for 60 g smolts <br />(BC's program released 800,000 smolts in 1987). They determined that they could gain <br />30-40 percent smolt-to-adult survival by lower river releases, i.e., tide water. They had <br />much lower survival for groups released only 10 km upstream. BC's major limitation in <br />steelhead research is returning adult enumeration. <br />Parr - BC released 355,000 parr from brood year 1987. They use two strategies for parr <br />releases, both with 15 g fish (30/lb). This program began in 1987 and the return data <br />for the Coquihalla River demonstrated aparr-to-adult survival of 2.6 percent. They <br />expected 3.2 percent parr-to-adult survival.
