In April to May, when the water is 44 to 52 degrees Fahrenheit, female yellow perch swim to their favorite spawning places near weeds or submerged brush and lay gelatinous strands of eggs that are up to seven feet long.
Most strands of yellow perch eggs contain 28,000 eggs each!
That’s a lot of mouthwatering bites for newly hatched fry of walleye and bass and northern pike.
Perch have brush like teeth used to eat small aquatic insects, and comb like gill rakers that strain minute zooplankton from the water.
Game fish like walleye and northern pike have long, sharp canine teeth for grabbing and eating other fish.
Perch are relatively slow swimmers.
