Freshwater Drum - Spawning Behaviour
Males reach maturity at four years. Females reach maturity at five or six years.
Spawning occurs in the Red River, mid-to-late June when the water temperature is between 21 to 23 degrees Celcius.
Spawning is completed mid-water; females release their eggs, males release their sperm, and fertilization is random.
The eggs float to the top of the water and hatch within two to four days. Fry descend to the bottom where they live most of their lives.
Mature females will have a clutch of 34,000 to 66,500 eggs. Survival rates are low because no parental care is provided and the eggs are broadcast.
