does temperature affect the health of
in the water?
Temperature can affect an organism's
resistance to disease, parasites, and toxic waste. Environmental
temperatures that are lower or higher than normal can make an organism
more sensitive to pollutants and diseases caused by bacteria, viruses,
Fish and other organisms that are
exposed to altered environmental conditions (e.g. temperature or
amounts of dissolved oxygen) are referred to as being stressed.
When fish and other organisms are stressed they may not be as healthy
or live as long.
water + waste water discharge = stressful
Fish respond to changes in temperature
just like we do. If we are too hot or too cold, we get uncomfortable.
If we are too hot or too cold for too long a time, it can affect
Let's observe how the goldfish might

is in a bowl containing water at just the "right" temperature.
Click on the bowl to heat and then cool the water and watch how
