Not all individual hatcheries were considered failures, however. In Maine it is generally thought that hatcheries have played a positive role in maintaining salmon stocks on the Penobscot. However, recent habitat improvement may also play a big part in this.

Hatcheries began to try to increase salmon in the Penobscot in the 1960s, with little success. Then there was a successful effort to clean up the polluted river, and in 1974 a more advanced hatchery was established on the cleaner waterway. Although only by the hundreds, not the thousands, salmon were starting to come back. Hatcheries have not had the same success on the Connecticut River, which did not receive the same level of habitat improvement as did the Penobscot. This outcome suggests that it was the habitat improvements, not the hatchery, that helped the Penobscot salmon. Today, the Penobscot salmon population is still far below historic levels but is improving dramatically following recent dam removals. It’s just not clear how much, if any, of the credit should go to hatcheries.

This is also true in the Tyne. The Tyne begins at the Scottish border and flows through northern England, past Newcastle, and into the North Sea. It was once one of Britain’s great salmon rivers. Elizabeth Cleland singled it out in her 1755 Scottish cookbook:
