Ecology Disrupted

The evidence is that the population dropping because since they can't swim upstream, they can't reproduce si the population ends up decresing.

This is an abiotic factor change since people are putting dams in and the dams are nonliving so they are abiotic.

The salmon can't reproduce because the water pressure that the dams are creating are too hard for the salmon to swim to where they need to reproduce. Humans put the dams there because we wanted electricity.

The soloution to this problem is to not make the dams not in use when they have to reproduce and swim upstream and wait untill the salmon do not need to swim upstream.

Chinook salmon are currently the most economically important commercial fishery resource in the Klamath River, and are caught in ocean fisheries from Monterey Bay to the Columbia River.
