The effect of the presence of stone blocks in the spawning habitat on the reproductive success of mature male parr of Atlantic salmon Salmo salar of various sizes and ages was tested in an artificial channel. Shelters allowed smaller individuals to contribute to egg fertilization as much as large parr, suggesting that the size-based dominance observed in a shelterless habitat was not maintained in a more complex habitat.
在人工渠道中测试了产卵栖息地中存在石块对不同大小和年龄的成熟大西洋鲑雄性幼鱼繁殖成功率的影响。庇护所允许较小的个体与大个体一样为卵子受精做出贡献，这表明在无庇护所的栖息地中观察到的基于大小的优势在更复杂的栖息地中并没有得到维持。
