Hatcheries and breeding programs use wild-caught fish reared on artificial diets. Understanding how fish adjust to a new feeding environment in this context might contribute to improving survival and growth outcomes under artificial conditions. In this study, we examined the growth and survival of wild white-spotted charr (Salvelinus leucomaenis pluvius) on a diet of commercial pellets in an artificial rearing environment. Our results revealed that pre-study fork length has a significant influence on pellet consumption, and thereby survival. The primary factor contributing to growth was the number of days until an initial increase in body weight. Post-mortem examination of deceased fish and their condition indicated that in all cases, the most likely cause of death was starvation. These results accordingly indicate that starvation tolerance and the ability to adjust to a new feeding environment are key factors in the survival of wild charr, whereas the time taken to acclimate is a key factor contributing to growth.

孵化场和育种计划使用人工饲料饲养的野生捕获的鱼。了解鱼在这种情况下如何适应新的饲养环境可能有助于改善人工条件下的生存和生长结果。在这项研究中，我们研究了野生白斑炭疽病 ( Salvelinus leucomaenis pluvius)的生长和存活情况。) 在人工饲养环境中食用商业颗粒饲料。我们的结果表明，预研究叉长度对颗粒消耗有显着影响，从而对存活率有显着影响。促进生长的主要因素是体重最初增加之前的天数。对死鱼及其状况的尸检表明，在所有情况下，最可能的死因是饥饿。这些结果相应地表明，饥饿耐受性和适应新饲养环境的能力是野生炭疽存活的关键因素，而适应环境所需的时间是促进生长的关键因素。
