요약	Translocations often use captive-reared animals to help bolster or re-establish wild populations. Captive-rearing provides safety and ample amounts of food so animals can be released as larger, older individuals. However, captive environments ar
요약	I examined the efficacy of using semi-natural conditions in a captive setting to advance eastern hellbender head-starting techniques and improve standard rearing practices. I developed novel forms of environmental enrichment, predator conditioni
요약	Hellbenders are commonly reared in aquaria that lack environmental stimuli and because of their inexperience with moving water may be more susceptible to downstream movement following release. I investigated the effects of rearing hellbenders wi
요약	Although some anti-predator behaviors are innate, many animals are brought into captivity at young ages before they have ever encountering a predator. Captive hellbenders identify predatory fish as threats, but may be more vulnerable to predatio
요약	Captive environments often lack natural microbial reservoirs, have filtration systems that remove excess microbes, and are maintained in hygienic ways to prevent the spread of disease. Subsequently, captive hellbenders may have depauperate micro
요약	This dissertation provides critical information to advance head-starting techniques for hellbender captive-rearing programs. The presence of water velocities, predator kairomones, and free-floating river microbiota are all representative of natu
