Comparison of Diploid and Triploid Atlantic Salmon ( Salmo salar ) Physiological Embryonic Development
Diploid and triploid Atlantic salmon show distinct physiological differences including heart, brain, and digestive system morphology, propensity for certain deformities, temperature tolerance as eggs and once hatched, and different nutritional requirements. Whilst several studies have looked in deta...
