Description
Five authors led by Luca Dolfi build a cheap auto-feeder for a short-lived fish and test how meal pace shapes its life. The fish, the African turquoise killifish, lives just four to six months, which makes it a prized ageing model. Diet and meal pace can shift its growth and span, yet hand feeding caps how fine those tests can run. Their feeder can drop up to 36 meals a day with sharp timing.
Fish on near-all-day meals grew heavier but not longer than twice-a-day peers. Male lifespan held steady across all diets and paces in the trial. Females on the fast pace died sooner, most on rich diets. Egg output tracked diet fat and protein more than pace. The feeder opens fine diet tests that hand work could not run.
