The drugs, say researchers, increased the levels of serotonin in the fish, which in turn affected their swimming behaviour.

Consequently, do fish eat sludge?

They burrow and swim through the excrement, stirring it up, aerating it, and allowing millions of microorganisms and bacteria to naturally break it down. He's also found evidence that these fish actually eat the sludge.

What are sewage ponds?

A sewage lagoon is a large pond into which the sewage or effluent from the sewage system flows. Sewage lagoons are also called effluent ponds. Algae helps the bacteria break down the sewage and effluent. The wind helps with the evaporation of the water and serves to get oxygen into the water.

Can fish live in reclaimed water?

The fish live in a lake of reclaimed water, also called effluent. Reclaimed water also is used to replace groundwater and is banked underground for use during water shortages. All these uses of wastewater save drinking water for your tap.

Why does raw sewage affect aquatic life?

Bacteria use up oxygen in the water as they decompose the organic material in the wastewater, and the resulting lack of oxygen in the water kills the fish. The solids in sewage cause the water to appear dark and murky, which also affects the ability of fish to breathe and see around them.

How does sewage cause water pollution?

When sewage enters a lake or stream, micro-organisms begin to decompose the organic materials. Oxygen is consumed as micro-organisms use it in their metabolism. This can quickly deplete the available oxygen in the water. When the dissolved oxygen levels drop too low, many aquatic species perish.
