Each year, Genoa provides millions of eggs, fry, and fingerlings of many different species to state fishery stations, federal hatcheries, National Wildlife Refuges, Department of Army installations, and seven Native American Tribes to support ongoing fish management and restoration programs. Due to the close proximity of the Upper Mississippi River, each year the station collects walleye, northern pike, and sauger eggs during the spring spawning season. Other fish species are also collected at this time to assist in fish health monitoring of wild populations of fish completed by the Fish and Wildlife Service's LaCrosse (WI) Fish Health Center. A small number of fish are also collected to assist in ongoing aquatic research from research centers throughout the country.

Adults are collected in 4 foot fyke and hoop nets shown above. The eggs are fertilized with milt from the males, and brought back to the hatchery to continue to develop until they are developed enough to ship safely. The eggs and fry are shipped in plastic bags filled with water and pure oxygen to their new homes by overnight delivery.

Fish are also reared at the station for further growout in existing rearing ponds, and stocked in the fall when their larger size increases post-stocking survival.
