Stocking Walleye Sander vitreus is a common management tool to augment populations where natural reproduction is limited. Some hatcheries have progressively raised larger fingerling Walleye to improve post-stocking survival; however, little is known about large fingerling Walleye poststocking survival and behavior. Our objectives were to evaluate large fingerling Walleye (>200 mm TL) post-stocking daily apparent survival, depth use, dispersal, and home range size in three Iowa, USA lakes. Walleye (209-265 mm, n=15 per lake, 45 fish total) were implanted with radio tags, stocked 26-30 October 2017, and tracked until 30 May 2018. Cormack-Jolly-Seber recapture models estimated Walleye apparent survival increased with days post-stocking and Walleye length, resulting in 76% (95% CI: 44-89%) cumulative survival by May. Walleye in Brushy Creek were located in deeper water (mean = 5.1 m, SE = 0.2) than Big Creek (mean = 3.3 m, SE = 0.2) or East Okoboji (mean = 1.7 m, SE = 0.1) but depth use did not vary with days post-stocking. Walleye dispersed an average of 1,355 m (SE = 234) within 13 d across all lakes with home range size larger in Big Creek (67.9 ha, SE = 21.7) than Brushy Creek (15.5 ha, SE = 15.7) and East Okoboji (31.0 ha, SE = 14.0). Our results indicate Walleye post-stocking survival is high overall with most mortality occurring within 20 d as Walleye are dispersing, suggesting managers should focus on improving survival during this critical period to improve stocking success.
