In this episode of The Aquaculture Podcast Show, we focus on production efficiency challenges in Atlantic salmon, with special attention to early maturation and grilsing. Explaining how genetics, sex, and nutrition interact to regulate maturation through gene expression rather than fixed outcomes. Key insights highlight precision feeding, sex specific management, and transcriptomic control as practical tools for producers. Get actionable strategies to optimize growth while reducing maturation risk. Listen now on all major platforms!

Inspired by the 2024 article titled "Sex-, development-, and nutrition-dependent expression of a major age-at-maturity gene in Atlantic salmon" by Åsheim, Eirik Ryvoll, et al.
