鲑科鱼类在形态、生理和行为上表现出相当大的地理差异。了解这种变化背后的遗传机制可能有助于提高水产养殖种群，确定独特的种群保护，并确定自然适应和驯化的遗传因素。作为鲑鱼行为多样性的遗传解剖的第一步，我们研究了虹鳟鱼（虹鳟鱼mykiss）来自地理上不同的源种群与不同的驯化历史的四个克隆系之间的行为模式的变化。将克隆系与两个远系杂交（即，非纯合的）雌性，并在相同条件下饲养和测试所得后代。克隆系对平均游泳水平、躲藏、觅食、惊吓反应和攻击水平有显著的遗传效应。多重比较表明，源种群的驯化历史对这些行为模式有很大的影响。两个克隆系的后代来自圈养超过100年的人口表现出减少捕食者回避行为模式和增加侵略相比，最近驯化的人口的两个克隆系的后代。这些结果将有助于未来调查的遗传因素，这些行为模式的影响驯化的群体变化。
Salmonid fish show considerable geographical variation in morphology, physiology, and behavior. Understanding the genetic mechanisms underlying this variation could be useful for enhancing aquaculture stocks, identifying unique populations for conservation, and determining the genetic factors underlying natural adaptation and domestication. As a first step toward the genetic dissection of salmonid behavioral diversity, we examined variation in behavior patterns among four clonal lines of rainbow trout (Oncorhynchus mykiss) derived from geographically diverse source populations with different domestication histories. Clonal lines were crossed with two outbred (i.e., not homozygous) females, and the resulting progenies were reared and tested under identical conditions. Clonal line had significant genetic effects on mean swim level, hiding, foraging, startle response, and aggression level. Multiple comparisons suggest that domestication history of the source populations had a strong influence on these behavior patterns. Progeny of two clonal lines derived from populations reared in captivity for over 100 years exhibited reductions in predator avoidance behavior patterns and increases in aggression compared to progeny of two clonal lines from more recently domesticated populations. These results will facilitate future investigation of the genetic factors underlying population variation in these behavior patterns influenced by domestication.
