Survival--Muskellunge were detected 245 times (mean \(\pm\) standard error [SE] = 16.3 \(\pm\) 3.9 times fish\({}^{-1}\)) during 45 tracking events at Spirit Lake and 156 times (mean \(\pm\) SE = 15.6 \(\pm\) 4.4 times fish\({}^{-1}\)) during 17 tracking events at Lake Cornelia between 20 May 2023 and 8 September 2023 (Table 1). Only three Muskellunge (two at Spirit Lake and one at Lake Cornelia) were confirmed dead by 8 September 2023. Of these, one fish (Fish 8.071) was not located after 12 DPS and went missing until 102 DPS when it was found deposited (no movement on five separate tracking events) in the middle of the northeast bay of Spirit Lake in 5.1 m of water. Fish 8.152 was first located 12 DPS, 1093 m from the stocking location in Spirit Lake, and had movement patterns consistent with a live fish up to 101 DPS. At this time, the fish had moved nearshore (within 25 m of shore), and the tag was subsequently recovered on the bank (approximately 10 m from shoreline) at 112 DPS. At Lake Cornelia, Fish 9.332 was located alive during each tracking event between 2 and 11 DPS in nearshore (<15 m of shoreline) habitats (e.g., docks with aquatic vegetation) but went missing during the tracking event on 17 DPS. A social media post confirmed the capture and harvest of a radio-tagged fish that was misidentified as a Northern Pike, and the fish was considered dead thereafter. All other radio-tagged Muskellunge displayed frequent movement and were considered alive at the end of the 111-112-day study. Therefore, observed Muskellunge survival was 86.7% (13 of 15 fish) in Spirit Lake and 90.0% (9 of 10 fish) in Lake Cornelia, with a cumulative survival rate of 88% (22 of 25 fish). Dispersal and movement--Muskellunge dispersal with the first 25 DPS ranged from 55 to 2436 m (mean \(\pm\) SE = 606 \(\pm\) 41 m fish\({}^{-1}\)). Muskellunge dispersed quickly after stocking, as fish were located more than 1090 m from stocking locations by 2 DPS (mean \(\pm\) SE = 289 \(\pm\) 44 m fish\({}^{-1}\)), but dispersal was higher at Lake Cornelia than at Spirit Lake within the first week poststocking (\(t\) = \(-\)2.78, pooled df = 78, \(p\) = \(<\) 0.01). Muskellunge dispersal at Spirit Lake (\(n\) = 104 observations; mean \(\pm\) SE = 552 \(\pm\) 552 m fish\({}^{-1}\)) differed among DPS (_df_ = 10; F = 5.82; \(p\) \(<\) 0.001), with increased dispersal rates observed at \(\geq\)13 DPS compared to those within the first 2 DPS (\(p\) \(<\) 0.05; Figure 2). Dispersal at Lake Cornelia (\(n\) = 48 observations; mean \(\pm\) SD = 725 \(\pm\) 376 m fish\({}^{-1}\)) did not differ among DPS (_df_ = 4; F = 1.16; \(p\) 0.3429; Figure 2). Muskellunge mean daily movement ranged from 0.48 to 689.46 m day\({}^{-1}\) (mean \(\pm\) SE = 81 \(\pm\) 4.9 m day\({}^{-1}\)) and was generally higher at Spirit Lake (mean \(\pm\) SE = 92 \(\pm\) 7.2 m day\({}^{-1}\)) than at Lake Cornelia (mean \(\pm\) SE = 64 \(\pm\) 5.9 m day\({}^{-1}\)). Muskellunge movement rates differed among weeks (\(p\) \(<\) 0.001) but did not differ among lakes (\(p\) = 0.745), and the lake \(\times\) week interaction term was insignificant (\(p\) = 0.147; see \(F\) values, Table 2), indicating that Muskellunge movement behavior was similar among lakes through time. Mean daily movement was highest in both lakes within the first week poststocking, after which rates generally declined (Figures 3 and 4).

Muskellunge proximity to shore, depth, and aquatic vegetation usage--Muskellunge were located in nearshore (<25 m from shore) habitats during 27 of 402 (6.7%) locations and frequently preferred offshore habitats in both lakes (mean \(\pm\) SE = 226 \(\pm\) 8.7 m).
