-
aSurvival estimates from release to LMN were not produced for subyearling Chinook salmon ranging in fork length from 80 mm to 89 mm or 120 mm to 129 mm due to low PIT detection probabilities for these length-classes, causing unreliable estimates. Sample sizes to LMN were thus 32,904 (PIT) and 8,641 (AT).

- Fork length indicates the range of fish sizes included in the analysis for a given year and stock. Tag burdens were calculated as weight of fish/weight of tag (PIT + AT tag weights).
