How do you think stocked salmon disrupt natural wild populations?
Babygirl7265
Stocked salmon disrupt natural wild populations because it gets the individual species of a community out of sync. The larger fish and animals that eat the salmon will not be able to keep up with the rapid increase in population and progeny of the stocked salmon. In addition, the animals that salmon prey on (small aquatic species such as plankton) may all be consumed and disappear from the community altogether.

Why do hydroelectric dams disrupt the life of aquatic animals?
Because they disrupt the natural flow of the body of water they built in ! A simple example would be salmon spawning. The adult salmon, though spending its life at sea must by instinct return to the river where it spawned in order to breed. If a dam is built across the river, the salmon is blocked from reaching its spawning ground - and dies without reproducing.Man-made dams affect lots of different wildlife.
What forces threaten salmon populations?
Many forces threaten salmon populations, there are forces such as over fishing, fishing techniques (purse seine), dams that block the upstream travel of salmon, reservoirs and lakes behind dams, damage from logging in the form of disturbed soil, and mining damage.

Why do wild salmon populations face the threat of extinction while pet goldfish populations are in no such danger?
Salmon is a public good, which means that people can profit from catching, killing, and selling salmon for consumption. Goldfish on the other hand are a private goods. They are bred and sold, which only contributes to goldfish population growth.

Is there fish in the crater lake in Oregon?
Originally Crater Lake did not hold any fish, but between 1888 and 1941 lake was stocked with 1.8 million trout and salmon including Rainbow trout, Brown trout, Cutthroat trout, Steelhead trout, Coho or Silver salmon, and Kokanee salmon.
