The gargantuan rainbow trout at Mt. Lassen Trout Farms are hatched from eggs manipulated to produce fish with three sets of chromosomes instead of two, enabling faster and greater growth. Although some fishermen call them freaks and won’t touch them, the fish do have a following among anglers at “pay” lakes. (Robert Gauthier / LAT)
Fish bait also is developed at the trout farm. (Robert Gauthier / LAT)
