A research analyst heads the program, with a staff of four reporting to him and the Marine Resources chief. The proposal was presented to the State Per- sonnel Board and the Department of Finance for ap- proval at the end of the biennium. Simultaneously, the department compiled a list of most urgent problems facing it as the protector of salmon. Here are the items listed, not in order of priority: 1. Determine necessary water flows for salmon and steelhead passage and spawning in all rivers, in ad- vance of water project construction. Each water proj- ect changes a stream. Water flows must be insured and the department has to know how much to demand. 2. Develop ways to predict water temperatures that will result from water projects. Will the downstream water be suitable for salmon? 3. Continue to conduct and improve annual spawn- ing stock inventories for all rivers. Not only must the adequacy of the stock be known, but inventories are essential in justifying fishery facilities ( Nimbus Hatchery). 4. Determine optimum number of spawners for each stream. Too few fish spell disaster; too many means that the fishermen could have taken more. 5. Determine production of downstream migrant fry. Determine causes and amount of loss along fresh- water migration route, during brackish water exist- ence, and until time of entry into ocean catch (22-inch king salmon are in their second year of life). Mark- ing experiments have indicated that only 1 percent of the fr_\' survive to be taken by fishermen or to spawn. Of this number, fishermen landed percent and percent escaped to spawn. Causes of this high mortality must be found and corrected insofar as pos- sible. 6. Determine effect on survival of variations in oceanic conditions. Recent information indicates that catches vary in relation to changes in sa
