Fertilizer IS nutrient rich. When it gets into lakes and ponds, it causes massive algae blooms. These massive algae blooms soon die off, contributing to massive amounts of carbon dioxide accumulating in the lake or pond (and thus a decrease in oxygen concentration). Such a decline in oxygen concentration will suffocate fish and thus cause fish kills.

How does fertilizer runoff kill fishes and other organisms in lakes?
Fertilizer rnoff can kill fish by darkenning the water and not allowing sunlight to come through. If sunllight can not come through, SAV's(Submerged Aquatic Vegitation) dies. Most fish eat SAV"s. If the primary source of fish food is dead, the fish die too.
Is the fire retardant used in aerial fire-fighting toxic?
Yes, primarily to fish. The retardant is a fertilizer slurry. When dropped in water, the fertilizer turns to ammonia, which is toxic to fish and some other aquatic organisms. The degree of toxicity depends upon the dilution factor. Retardant drops in small streams have been known to kill trout for several miles downstream.
How can dumping sewage into an aquatic kill fish?
unhealthy water to have can kill from choking
How do fertilizers affect animals?
Chemical fertilizers get washed in with the natural watershed, and promote excessive algae growth in streams, ponds, and lakes. The algae consumes huge amounts of oxygen from the water and can kill fish and other aquatic life.
What does river pollution have?
River pollution could be toxic waste discharged from a factory (or untreated sewerage) - which can cause ulcers, gills and scale damage, and kill fish and other aquatic life. Or, the pollution could be from fertilizer run-off from farmland - which can cause excessive weed and algae growth chocking the river - even leading to lack of oxygen in the water.
Can garden fertilizer kill cats?
Yes, garden fertilizer can kill cats. Don't let your cat outside after using fertilizer.
Can you feed a fighting fish a fish?
well not exactly if you want to kill your other fish then........sure! why not? if love your fish, why kill it?
Why is overfishing like it is?

How is a natural caused fish kill different from a human caused fish kill?
One is caused by humans, the other is not.
Do betta eat other fish?
they dont eat other fish they just attack them to kill
Is algae a sign of a healthy stream?
No: algae blooms come from eutrophication of water, or excess nutrients. These nutrients come from eroding soils, plant matter such as leaves or grass clippings, fertilizer runoff and pet waste. Algae blooms grow in the presence of these pollutants. As they die and sink to the bottom, they are decomposed by bacteria. This process depletes oxygen in the water, making it hard for fish and other aquatic organisms to breathe. If the algae blooms are large enough a fish kill can occur; the fish and other animals litteraly suffocate from lack of oxygen and die. In short, algae is a sign of nutrient pollution and poor conditions for fish.
