Anatomical and pathological characteristics of ribs in the Atlantic salmon ( Salmo salar L.) and its relevance to soft tissue changes
Abstract Studies on the anatomical and pathological characteristics of ribs in farmed Atlantic salmon ( Salmo salar L.) are warranted due to their possible association with red and melanized focal changes (RFC and MFC) in the fillet, a major quality and animal welfare concern. In this work, we provi...
