Freezing water temperatures

Did you know that salmon need a certain water temperature to survive in the water that they live in?
 

If it is below freezing they will die, but if you protect them they will be fine. Once the temperature starts going up, the eggs will start to hatch. If the temperature is higher than 50 degrees, it could kill the salmon. It has to be just the right temperature.
Also, if a mom has 500 babies, you will be lucky if you have two of them survive!

The water temperature is usually very cold when the eggs are laid.
When the temperature rises, they start to hatch and right now, the temperature of the tank is at 46 degrees Fahrenheit so our eggs are hatching.
