The story

Bones (歹) beside 直, straight: picture new life shooting straight up from what has died, like mushrooms on a fallen log. 殖 is to multiply: 繁殖 is breeding, 増殖 proliferating, and 養殖 is fish and oyster farming, as on Hiroshima's oyster rafts.

Used in 養殖 (youshoku, aquaculture/farming), 繁殖 (hanshoku, breeding), and 増殖 (zoushoku, multiplication)
