Dynamic population breeding improves turquoise killifish husbandry

Originally from southeastern Africa, the turquoise killifish (Nothobranchius furzeri) lives in seasonal bodies of water that form during the rainy season and disappear again during the dry season. The fish is highly adapted to this seasonal cycle: It completes its entire life cycle—from hatching through reproduction to natural death—within a few months. Its short lifespan makes it a valuable model organism for aging research, as processes that often take years in other vertebrates can be studied in killifish within a few weeks.
