Concurrence of lower jaw skeletal anomalies in triploid Atlantic salmon ( Salmo salar L.) and the effect on growth in freshwater
Abstract Triploid Atlantic salmon populations are associated with higher prevalence of lower jaw skeletal anomalies affecting fish performance, welfare and value deleteriously. Anomalous lower jaw can be curved downward ( LJD ), shortened ( SJ ) or misaligned ( MA ). Two separate groups of triploid...

Severity of both LJD and SJ increased in the SJ group only. Opercular shortening recovery was observed in both groups but at a slower rate in the SJ group.
