Sewage can deplete oxygen levels in rivers as bacteria breakdown the waste, causing fish suffocation. It can also introduce harmful chemicals and pathogens into the water, leading to fish mortality. Additionally, sewage can disrupt the natural balance of the ecosystem, impacting fish health and survival.
One of the main concerns of dumping untreated sewage is bacteria levels. Sewage is teaming with bacteria far above a safe level. When this is poured into a river it can create many problems. Some of the most prominent are that it makes the water dangerous swim in and it makes the water undrinkable. Also, it can kill the plants and animals living in the river and make the remain life sick and dangerous to eat because of the bacteria and parasites that once lived in the sewage and now live in the fish.

unhealthy water to have can kill from choking
Sewage contains many different contaminants that can harm fish. These include: * Biologically active materials: These materials decompose my microbial action. This activity reduces the oxygen dissolved in the water and essentially suffocates the fish * Cleaners and othe pH altering materials: These materials affect fish by attacking the gill membranes * Pharmaceuticals: These materials have along term impact on fish reproduction * Parasites: Sewage can contain parasites that infect fish * Temperature: The warm sewage can kill fish quickly by thermal shock and oxygen reduction or on a long term basis by changing the makeup of the local ecosystem * Sedimentation: Solids from the sewage can cover breeding or spawning areas * Nurients: The nutrients in the sewage can eutrophy the local waters leading to algal blooms, oxygen depletion, the overgrowth of undersitable species or stratification of the water into aerobic and anaerobic layers
well yes it may do depending what is in the sewage it may kill alot of fish it may spread a diasies that may kill alot of fish in the lake.
Ich will kill every fish in the tank. It is deadly if left untreated. You will need to get to a pet shop and buy some Whitespot /Ich medication ASAP.

They are small and have a lot of fish and plants in them.Ponds will accumulate muck on the bottom if the water remains untreated with a beneficial bacteria.
it has water pollution because of it's sewage, septic tanks, and cesspits. They also over fish in the Keys.
Wetlands provide places where baby fish can grow into juvenile fish before they move to rivers or the ocean. They now provide a place that treats sewage keeping it from polluting rivers or the oceans.
becase they dont have very high ammune system
