Was this misplaced by chance? Tiger Musky is a sterile hybrid between a musky and northern pike, you see them in a lot of places much like you see the mule counterpart to horses. I read a study saying that a very scant number of female tiger muskies may be fertile, all tiger musky males are sterile, and thus since they are more or less a "mutt" in the fish world, their chances of reproducing another tiger musky is slim to none. Most all are bread a female musky egg to a male northern pike sperm and in controlled hatchery conditions. Like mules they are produced for a reason, which is usually to control invasive species and to provide a good sport fishery since they are voracious eaters and grow in size quickly. To even be able to genetically engineer a pure viable strain you would need to have both sexes able to fertilize so the chances of a pure viable strain (like golden retrievers parents producing golden retrievers offspring) is in my oppinion is nil.
