Six triploid individuals were found in a full-sib family of 11 adult rainbow trout (Salmo gairdneri) from a domesticated hatchery stock. The triploid individuals were normal in size and external appearance, had underdeveloped gonads, and showed no evidence of 3n/2n chimerism or mosaicism. XXY triploids were males, suggesting that the Y chromosome is male determining in trout. Because they may avoid production losses associated with sexual maturation in normal fish, triploid trout and salmon could potentially be useful in fish culture.
在一个来自驯化孵化场种群的由11条成年虹鳟（Salmo gairdneri）组成的全同胞家系中发现了6个三倍体个体。这些三倍体个体在大小和外观上正常，性腺发育不全，并且没有3n/2n嵌合体或镶嵌性的证据。XXY三倍体为雄性，这表明Y染色体在鳟鱼中决定雄性性别。由于三倍体鳟鱼和鲑鱼可以避免正常鱼类中与性成熟相关的产量损失，它们在鱼类养殖中可能具有潜在用途。
