Rocks used as spawning cover averaged 200 square inches and were found in water depths averaging 34 inches. The eggs are amber-yellow and are very large, ranging between 3.5 and 4 mm in diameter, with the whole egg mass enveloped by a gelatinous material. A female stonecat may produce between 200 and 1,200 eggs per year.
The size of the clutch varies proportionately to the size of the female; an average of 2,640 eggs per kilogram of fish are laid. On average each female flathead lays a clutch of roughly 100,000 eggs. The role of the male catfish in fanning the clutch is to provide oxygen to the eggs through the use of his fins.
