It is unclear whether this migration to sea water is genetic or simply opportunistic, but it appears that any population of rainbow trout is capable of migrating to or surviving in the sea if the need arises (FishBase, 2003).

As a consequence, native cutthroat trout were often replaced by the introduced nonnatives, and hybridization between cutthroat trout and rainbow trout was common (Varley and Schullery 1983, 1998). trout as an invasive species is to implement programs supporting the native Members of the Lake Trout Suppression Scientific Review Panel, Dr. Robert E.

Despite these introductions, Yellowstone cutthroat trout flourished in many parts of their native range within the Park, and until the 1990s, Yellowstone Lake supported the largest genetically pure population of Yellowstone cutthroat trout on earth (Gresswell and Liss 1995). Actinopleygii The study also highlights the importance of using and maintaining long-term datasets covering large regions to shed light on the complex ways climate and invasive species work in concert to affect native species. Given changes temperatures and climate change, it will be interesting to Anadronous The culprit for declines of both native trout species is likely climate change, researchers found, but the specific mechanisms of the declines varied by species. Rainbow trout is prized among fishermen because it puts up 1996. Darling, and W.R. Archibald, editors. Lake trout may never be completely removed from Yellowstone Lake, but the Panel believes that the National Park Service goal of restoring the Yellowstone cutthroat trout population to levels approaching those observed in the late 1980s and early 1990s is achievable.

During the 1950s-60s, 250,000 to 300,000 cutthroat trout were being captured by anglers each year (Gresswell and Varley 1988), rigorous creel surveys were conducted (Moore, Cope, and Beckwith 1952; Cope 1955), and experienced guides were on the water with their clients almost every day, but there are no records of lake trout being caught or observed (Kendall 1915; Simon 1962; Varley and Schullery 1983).

However, this amount is relatively small compared to the money that has been lost to businesses in and around Yellowstone National Park as the cutthroat trout population in the lake collapsed following the introduction of lake trout.

River otters in Yellowstone Lake depend on a declining cutthroat population. 2005. After the 1988 fires burned a quarter of the Yellowstone Lake watershed, there were no changes in cutthroat trout growth (Gresswell 2004), and spawning streams around the lake did not become choked with ash and fine sediments.
