The incubation environment had a significant effect on fork length (L(F)) and body mass (M) of Atlantic salmon Salmo salar fry at the time of emergence. Fry that were incubated in a new incubator design, that mimics the conditions in a natural redd (the Bamberger-Box), achieved significantly greater and attained a significantly higher M than those reared in conventional hatchery troughs for control. Fewer fry from the Bamberger-Boxes had visible deformities compared with those from the hatchery troughs. Results were consistent for five consecutive seasons using both wild and domesticated broodstock from genetically different origins. Survival from the eyed embryo stage in the Bamberger-Boxes and hatchery troughs was >93% during normal climatic conditions. Only larvae reared in Bamberger-Boxes, however, survived abnormally high water temperatures during one test season. The results demonstrate that the Bamberger-Box is an effective alternative to the conventional incubation technology.
孵化环境对大西洋鲑（Salmo salar）鱼苗出膜时的叉长（L(F)）和体质量（M）有显著影响。在新的孵化箱设计中孵化的鱼苗，该设计模拟了自然产卵床（Bamberger-Box）的条件，与在传统孵化槽中饲养的对照组相比，其体长显著更大，体质量显著更高。与孵化槽中的鱼苗相比，Bamberger-Box 中的鱼苗畸形数量更少。使用来自遗传上不同起源的野生和家养亲鱼，连续五个季节的结果都是一致的。在正常气候条件下，Bamberger-Box 和孵化槽中的眼胚成活率均超过 93%。然而，只有在 Bamberger-Box 中饲养的幼虫才能在一个测试季节中存活异常高的水温。结果表明，Bamberger-Box 是传统孵化技术的有效替代方案。
