What Happens To Fish When The Water Is Polluted

Pollution can directly kill or harm fish, or change the makeup of the fish’ surroundings, killing off sources of food or causing plant or algae overgrowth that starve the fish of oxygen.

Water Pollution Harms Fish Population. Water pollution harms fish populations in various ways. When nutrients wash into waterways through storm runoff, they deplete oxygen in the water that fish need to survive. Nitrogen and phosphorus typically enter streams and lakes from fertilizers, dog waste, and other sources.

The planet’s aquatic ecosystems are seriously threatened by water pollution caused by human activity, and, unfortunately, this seriously affects fish and other marines species.

Over time, these nutrients build up in the water and promote algae and water plant growth, and as they decay, they lower oxygen levels in the water. Algal blooms can be harmful to fish as they feed upon algae, toxins accumulate within the fish, and when a predator fish consumes that fish, they too are consuming higher toxin levels.

Why do fish not survive easily in polluted water?

Fish need a certain amount of dissolved oxygen to survive. The oxygen level can get out of balance quickly. In polluted water, there might be too high an amount of oxygen, consuming bacteria that decompose wastes. As a result, the oxygen concentration can then decrease to a threatening level.

Are fish dying because of pollution?

Of known causes, fish kills are most frequently caused by pollution from agricultural runoff or biotoxins. Ecological hypoxia (oxygen depletion) is one of the most common natural causes of fish kills. The hypoxic event may be brought on by factors such as algae blooms, droughts, high temperatures and thermal pollution.
