Results show that the phosphate rocks reduce the amount of water-soluble lead in contaminated soils by 57 percent to 100 percent. The technology has been patented by Ohio State and the Environmental Protection Agency. It can also be used to treat soil contaminated with other heavy metals, such as zinc, aluminum, cadmium and possibly uranium. Other researchers on the project are with EPA and the University of Florida. The muskie is a sport fish.
Females grow faster and live longer and thus are better for stocking.
The process irradiates muskie sperm, then heat-shocks the eggs, producing only female muskies. Then the babies are switched to males by exposing them to masculinizing hormones. Males that produce only X chromosomes and X sperm. Breeders who use this sperm will get all females. We travel this month to Ohio's old lake bed region.
