Kelp causes the fish population to decrease because it provides rare shelter for them in open water, although this is a good thing it can also attract predators.

The salinity of the ocean causes the fish population to decrease because most fish species egg fertilization and incubation depend on salinity.

Predators cause the fish population to decrease because the fish are their prey so they are often being eaten.

The increase of wind affects the fish population because it creates currents in the water that can move big groups of fish.

An increase of urban runoff causes the fish population to decrease because pollutants in storm water runoff can negatively impact the development of aquatic life.

Ocean temperature affects the fish population because as water warms up, the fish requires more oxygen to function because warm water contains less oxygen than cold water.

An increase of upwelling causes fish population to decrease because in areas where upwelling occurs, the surface water that is moving away from the shore can take surface organisms with it.

An increase in ocean acidification causes the fish population to decrease, it results in higher vulnerability to predators.
