From the California Academy of Sciences:
Specimens from 1895 Save Today’s Salmon
A local lumber company claimed that the salmon were not native to central California, but had instead been introduced by fish hatcheries and were therefore ineligible for protection.
Coho specimens at the Academy, however, refuted that claim.
The specimens were collected in Santa Cruz County in 1895, pre-dating any hatchery records.
Based on this and other evidence, the National Marine Fisheries Service not only rejected the lumber company’s petition to de-list, but also elevated the coho salmon‘s status from threatened to endangered.
Scientists found that coho salmon became sick and nearly died, within just a few hours of exposure to polluted stormwater. But chum salmon showed no signs of ill-effects after prolonged exposure to the same water: here.
