In addition to accidental aquaculture escapees, an increasing number of freshwater fish expressing different domestication levels are voluntarily released into the wild primarily as stocking supplement for fisheries and for conservation programmes. Because domestication modifies individual traits and because subtle changes in intraspecific variability can impact ecological dynamics, we argue that these purposeful introductions of domesticated fish may impact the functioning of recipient ecosystems. We posit that purposely introduced domesticated fish could be considered as native invaders and be investigated and managed using frameworks developed for biological invasions. Studies identifying the relative importance of the different ecological mechanisms leading to these ecosystems impacts and quantifying how the intensity of introduction and the level of domestication modulate their ecosystem impacts are needed. This will lead to a better appreciation of how the benefits from releasing domesticated fish are offset by the ecological costs on freshwater ecosystem functioning caused by human‐induced local modification of intraspecific diversity patterns.

驯养的淡水鱼是生态系统变化被忽视的罪魁祸首吗？

除了意外的水产养殖逃逸者以外，越来越多的淡水鱼在不同的驯化水平下被自愿释放到野外，主要是作为渔业和保护计划的补充鱼类。由于驯化会改变个体特征，并且种内变异的细微变化会影响生态动力学，因此我们认为，有目的地引入这些驯化鱼可能会影响受体生态系统的功能。我们认为，故意引入的驯化鱼类可被视为本土入侵者，并使用针对生物入侵开发的框架进行调查和管理。研究需要确定导致这些生态系统影响的不同生态机制的相对重要性，并量化引入强度和驯化水平如何调节其生态系统影响。这将导致人们更好地认识到释放人工驯化的鱼类所产生的收益如何被人为引起的种内多样性格局的局部改变所引起的淡水生态系统功能的生态成本所抵消。
