cutthroat x rainbow = cutt-bow... very common in major tailwater trout fisheries.

pink x chinook = pinook.... established population in Great Lakes.

pike x musky = tiger musky ... stocked all over Midwest and Canada

brook trout x lake trout = splake.... commonly stocked in Midwest and Canada

coho x chinook = ??? conooks or chilvers ??? never heard of 'em until the Lewis article. Where I grew up in Alaska, this would never happen as run timing separates these species by one to three months., but here in the PNW where both species return in the fall, it seems probable. Must have poor survival traits overall or we would see a lot more of them.

Hatchery managers like these hybrids for stocking purposes because they are for the most part sterile and can't produce mutant offspring to interfere with wild stocks. They eventually become a put and take product for lakes.

Wonder if anyone has considered making sterile hatchery steelhead to minimize wild interaction? Problem is they probably couldn't get them to move into the river to spawn since they wouldn't have any viable sex organs.
