<p>Cohort reconstruction and population growth estimates for Chinook salmon (<i>Oncorhynchus tshawytscha</i>) on the Mokelumne River (USA) for all returning adults (Apparent population growth rate) and natural origin spawners (Actual natural population growth rate).</p>1<p>Age structure determined by coded wire tag recoveries of adult salmon from Mokelumne River Fish Hatchery (MRFH) caught in the freshwater sport fishery, carcass survey, or at MRFH (RMIS database). The number of survivors from each cohort is the sum of age 2, 3, 4, and 5 year olds produced in a given spawning year (cohort survival). For example, the return data in the ‘Adult Age Structure’ columns that are in the bold cells sum to the apparent cohort survival value for 1992.</p>
