First attempt at using a synthetic diet in short‐lived killifish, a vertebrate model of ageing
Journal of Fish Biology, EarlyView.Abstract Diet standardization of model organisms is crucial for experimental consistency and repeatability in laboratory research, yet laboratory fish often lack species‐specific, open‐formula standardized diets. This study aims to address this gap by testing the effect of macronutrient content on the performance of Nothobranchius furzeri, an ...
