| Notes | Hatchery salmon can interbreed with wild salmon, and damage the viability of the native fish run. In recent years, fishery managers have experimented with closing hatcheries. This was the case with the coho salmon hatchery on the Salmon River, which closed in 2007. What happened? This paper reports on what is known so far, and the news is good. “Although hatchery-origin spawners previously had accounted for most of the adults returning to the Salmon River, the naturally produced population did not collapse, and two viability metrics improved significantly after the Coho Salmon hatchery program ended: (1) adult abundance increased and (2) spawn timing expanded and moved closer to the historical timing.” (from the Abstract) Hatchery closure seems to be an effective strategy for promoting wild populations, but long-term monitoring is still needed. |
