In this episode of The Aquaculture Podcast Show, we break down why “everyday loss” can quietly erase production, using Norwegian Atlantic salmon baseline mortality data. Key drivers include temperature and salinity stress, geographic disease pressure, transfer timing, and the smolt paradox. Most importantly, sea lice control methods can nearly double mortality by adding physical stress and weakening protection against opportunistic microorganisms. Listen now on all major platforms!

Inspired by the 2021 article titled "Factors associated with baseline mortality in Norwegian Atlantic salmon farming" by Oliveira, Victor HS, et al.

“Larger initial smolt size does not automatically protect survival when extended freshwater periods risk desmoltification and harder saltwater adjustment.”
