%X The salmonid fisheries of the Columbia River Basin (CRB) have enormous socioeconomic, cultural, and ecological importance to numerous diverse stakeholders (eg state, federal, tribal, nonprofit), and there are a wide array of opinions and perspectives on how these fisheries should be managed. Although we appreciate Duda et al.'s commentary, it offers only one perspective of many in this context. The objective of our paper (Hand et al. 2018) was to provide justification for ¡°the importance of social¨Cecological perspectives when communicating conservation values and goals, and the role of independent science in guiding management policy and practice for salmonids in the CRB¡±. However, we did not intend to strictly advocate for a single course of action, and the available space within our paper's Panel 1 limited us from engaging in a thorough ecological debate. Although Duda et al. contend that the continued use of hatchery supplementation in response to the release of large amounts of sediment was a necessary step in salmonid recovery in the Elwha River (northwestern Washington State) following the removal of the Elwha and Glines Canyon dams, they also point out that threatened migratory species such as bull trout and Pacific lamprey ¡°that are not and have never been in hatcheries are also recolonizing upstream of the dams¡±. As lamprey and bull trout are expanding and recolonizing without hatchery support, this is counter to Duda et al.'s implication that hatchery supplementation is necessary for recovery of threatened species. Further, they acknowledge that there exists ample science ¡°demonstrating the potential for negative consequences of fish hatcheries¡±. Regardless, the goal of our Panel 1 on the Elwha was simply to highlight the uncertainty and current social¨Ceconomic debate over whether hatchery propagation is always a necessity for salmon recovery: an issue that is not unique to the Elwha and that is pervasive throughout the native range of salmonids occurring in the Northern Hemisphere. Research indicates that wild salmonids possess numerous adaptations for surviving and adapting to major sediment pulse events (sensu Sedell et al. 1990; and see Waples et al. 2008), which are a naturally occurring phenomenon in the geologically active terrain throughout their range in the northern Pacific region. Hatchery intervention has been shown to disrupt the evolution of important life©\history traits, such as natal homing, that have both behavioral and genetic components (Bams 1976; Dittman and Quinn 1996; Ford et al. 2015).
