The muskie spawns when the water temperature is 48 to 59 degrees, about two weeks later than the northern pike. A 40-pound female can produce more than 200,000 eggs. They generally spawn twice, the second time about 14 days after the first time. Unlike the northern pike’s adhesive eggs, which cling to vegetation, the muskie’s eggs settle to the bottom, rather than the weedy in-shore areas northern pike use. This separation of spawning areas apparently prevents northern pike fingerlings from preying on newly hatched muskie fry. In other circumstances, however, late-spawning northern pike have been observed actively spawning with muskie; the hybrid offspring is called a “tiger muskie.”
