Fish populations and other aquatic resources are likely to be affected by changes in what aquatic factors? a. water temperatures b. disease c. water quality d. all of the above

Answer;

-All the above

(a. water temperatures b. disease c. water quality )

Explanation;

-Dissolved Oxygen and Water Temperature are among the factors affecting fish population; The solubility of oxygen and other gases will decrease as temperature increases, which means that colder lakes and streams can hold more dissolved oxygen than warmer waters. If water is too warm, it will not hold enough oxygen for aquatic organisms to survive.

-Water quality is also a key factor that affect the fish population, for example, the presence of normal levels of nitrates usually does not have a direct effect on aquatic insects or fish. However, excess levels of nitrates in water can create conditions that make it difficult for aquatic insects or fish to survive.

-Diseases also affect the fish populations and other aquatic resources .
