Comparison of aspects of the physiology and morphology of diploid and triploid Atlantic salmon Salmo salar ...
High mortality rates under suboptimal culture conditions and the incidence of lower jaw deformity (LJD) are problems associated with the commercial production of all female triploid Atlantic salmon (Salmo salar) within the Tasmanian Atlantic salmon industry. The current study investigates the primar...
