Reproduction
Perch mature at around two years of age and use a method called spawning to reproduce. What happens is that a female will lay her eggs in a spawning bed and the males will release their sperm into the water
around the eggs to fertilize them. Temperatures need to be around 45 to 52 degrees Fahrenheit and spawning must take place on sand. Once the eggs are fertilized, they harden very quickly and will hatch under normal temperatures within eight to ten days. From there they become little fish called fry. These fry still have yolks attached to them until they mature enough to a diet of microscopic organisms. After one summer they head to open water and eventually mature to adulthood.
