The manner in which adults (spawners) are distributed within the freshwater portion of a population's home range.
Metrics
1. The percentage of random, spatially balanced surveys that have more than 4 wild adult spawners/mile (percent occupancy)
2. Comparison of the spatial pattern of potential spawning distribution to that observed using SVB or other spatial statistics.
Evaluation Thresholds
Metric 1
Pass  the observed percent occupancy is greater than or equal to the marine survivalspecific occupancy target at least six times in any 12year period.
Fail  the observed percent occupancy is greater than or equal to the marine survivalspecific occupancy target five times or less in any 12year period.
Metric 2
Pass  the observed regularity ratio is not significantly different from a random distribution at least six times in any 12year period.
Fail  the observed regularity ratio is significantly different from a random distribution at least six times in any 12year period.
