This is what I found anyway:Spawning Habits
Unlike most hybrid fish species, wipers can reproduce in the wild, but only when backcrossing, which is spawning with one of its two parent species. Fishery managers have learned that they can eliminate a wiper’s presence in a lake by simply ceasing to stock them.
Wipers spawn in the spring, between March and May, normally when the water temperatures reach the mid to upper 50s. Spawning begins by females and males making runs to the mouths of a lake’s tributaries, where current can help disperse the eggs on the lake floor.
The females are approached by multiple males and forced to the surface where the eggs are released and rapidly fertilized by the males. The sticky eggs will then drift to the bottom and remain there for only two to threes days before hatching. Eggs are not protected by either parent, as both male and female wipers migrate back to open water as soon as spawning activity ceases. Due to natural mortality, caused mainly by small fish that consume the eggs and fry, the majority of the young will not live beyond their first year.
