Triploid Atlantic salmon Salmo salar have a higher dietary phosphorus requirement for bone mineralization during early development
Abstract The effect of a dietary phosphorus regime in freshwater on vertebra bone mineralization was assessed in diploid and triploid Atlantic salmon, Salmo salar . Fish were fed either a low phosphorus (LP) diet containing 10.5 g kg −1 total phosphorus or a normal phosphorus (NP) diet containing 17...
