Question

What is a cause of the decrease in the Atlantic salmon population?

O Predators are killing off a large number of the Atlantic salmon population.
Disease is responsible for decreasing the population of Atlantic salmon.
O Overfishing is responsible for decreasing the population of Atlantic salmon.
Pollution and dam building have greatly decreased the Atlantic salmon population.

Answer 1

Historically, dams, overfishing, and pollution led to large declines in salmon abundance.

Step-by-step explanation:

Overfishing is another source of death that can contribute to the decline of salmon. The weather affects the amount of food that is available to salmon in the ocean. Pollution and disease have also contributed to population declines.
