Summary of Steelhead
Steelhead Salmon (Oncorhynchus mykiss) are an endangered species of salmon occupying rivers and streams flowing into the Monterey Bay. O. mykiss are distict among salmon species because the are both facultativly anadromous and iteroparous. Both resident (rainbow trout) and anadromous (Steelhead) forms exist, and both have the potential to spawn repeatedly (Satterthwaite 2009).
Management Challenges
There is great variability in age of Steelhead emigration and return age, along with the probability of repeat spawning. There are 32 identified possible life history trajectories for Steelhead which presents a great challenge for managing the species (Thorpe 2007). Changes in freshwater conditions due to water management or climate change may alter demographic rates along with the current life history trajectories, sending fish on alternative trajectories with radically different demographic results (Satterthwaite 2009).
