Sturgeon eggs need certain habitat
conditions in order to survive. Sturgeon eggs are usually
found in and around large rocks. This way the eggs can fall
into the crevices
and predators have a hard time getting at them.
The eggs also have a better chance of surviving
if they are in areas where the water
current is very strong. Strong currents help disperse
eggs over a wide area, reducing clumping which can spread disease.
The temperature of the water in the river is also
very important. If the water temperature is too low,
eggs develop slowly and predators may have a chance to eat them.
At temperatures above 20 degrees Celsius, eggs die at very high
rates. The optimal temperature for egg survival is 14-16
Lake sturgeon eggs are commonly found in and around large rocks.
