A blue variant of the rainbow trout, which appeared in a French fish farm, displayed an iridescent body color that was cobalt blue on the back, lighter on the undersides, and silvery on the belly and which held up to adult stage. This color was supposed to result from a Tyndall effect involving a structural arrangement of melanin pigments because it disappeared when it was associated with a depigmenting gene. This blue variant appeared to be governed by an autosomal recessive gene. Blue fry survival and body weight were about 25% less than those of wild-type sibs, but no major problem was observed in further breeding performances, including reproduction. These features do not correspond with those of the blue variants previously described in the rainbow trout.
在法国一家养鱼场出现的虹鳟蓝色变种，其身体呈现出虹彩颜色，背部为钴蓝色，腹部颜色较浅，腹部为银色，且这种颜色一直保持到成年阶段。这种颜色被认为是由涉及黑色素结构排列的廷德尔效应导致的，因为当它与一个色素脱失基因相关联时就会消失。这种蓝色变种似乎受常染色体隐性基因控制。蓝色鱼苗的存活率和体重比野生型同胞低约25%，但在包括繁殖在内的进一步育种性能方面未观察到重大问题。这些特征与先前在虹鳟中描述的蓝色变种不同。
