Abstract. Three pairs of brood channel catfish Ictalurus punctatus were induced to spawn in aquaria supplied with flowing water from a reservoir filled with ground water (calcium hardness = 110 mg/L as CaCO 3 = 44 mg/L as calcium).

CATFISH a home range (area within which they remain), Male channel catfish also arrange eggs in the nest. Initially the male may ventilate the eggs with his fins as often as every five to ten minutes, although that action decreases with time. Egg production varies with a female’s size and age. Spawns range from 3,000 to 30,000 eggs, with large flathead females producing as many as 100,000

Eggs hatch in four to ten days at temperatures between 21 and 27°C (70–81°F); at optimum spawning and incubation temperatures (25°–27°C), embryos hatch in 4 to 6 days. Young absorb their yolk sacs and begin swimming (swim-up stage) 3–4 days after hatching. After yolk absorption, young catfish actively feed on a variety of foodstuffs and readily accept artificially prepared diets.

The time it takes for catfish eggs to hatch depends on water temperature. Channel catfish typically spawn in the spring, when water temperatures are between 70 and 84 °F (21 and 29 °C). At these temperatures, the time from spawn to hatch is 5 to 10 days (Fig. 3). The exact time of spawning usually is not known, so the age of eggs must be estimated visually.
