Topic Fish: Iron Gate Hatchery Coho 1970-2002
Caption:  Coho salmon returns to Iron Gate Hatchery have been highly variable since the hatchery began operation. There were low returns and a very high component of grilse in the early years during a period of acclimation of the non-native brood stock. Low returns in 1984 could be attributed to the El Niņo conditions that occurred in 1983 that are particularly hard on coho salmon. The return of only 269 coho in 1995, however, can not be explained by extremely poor ocean conditions. The Iron Gate coho population should be experiencing an upswing, since no commercial harvest of coho salmon has been allowed since 1994. Data from annual Iron Gate Hatchery reports.
