2 Lake trout in Lake Michigan Historically supported large commercial fishery % Wild lake trout, 2016 Extirpated in 1950 s Stocked since 1960 s No consistent natural recruitment until recently Encountered in 2011 while targeting bloater Multiple consecutive cohorts of suspected NR Courtesy of Great Lakes Mass Marking Program 2
3 Strains of gamete sources Eight potentially different strains Seneca Lake, Finger Lakes Isle Royal, Superior Marquette, Superior Apostle Islands, Superior Lewis Lake, Michigan historic Green Lake, Michigan historic Klondike Reef, Superior Parry Sound, Huron 3
4 Objectives 1) Identify suite of microsatellite markers that can delineate strains 2) Determine ability of microsatellites to assign pure strains and interstrain hybrids 3) Determine ancestry of wild recruits and compare to stocking records to investigate differential survival/reproduction 4
5 Study design objective 1 Strain differentiation 8 sources tested 561 Lake Trout Genotyped with 49 microsatellite loci 36 loci used in final analysis Removed loci: monomorphic, >70% missing data, failed HWE, showed LD Genetic structure Genetic distance (tree) Bayesian admixture (STRUCTURE) 5
6 Genetic structure of strains Nei s genetic distance Seneca Lake (Finger (Ontario) Lakes) Parry Sound (Huron) Klondike Reef (Superior) Isle Royal (Superior) Apostle Islands (Superior) Marquette (Superior) 98 Green Lake (Michigan) Lewis Lake (Michigan)
7 Genetic structure of strains Bayesian admixture (STRUCTURE) 100% 90% 80% 70% 60% 50% 40% 30% 20% 10% 0% 36 microsatellites, 8 sources, 6 genetic units, N=561 Seneca Lake, N=81 Isle Royal, N=62 Marquette, N=72 Apostle Islands, N=77 Lewis Lake, N=97 Green Lake, N=71 Klondike Reef, N=61 Parry Sound, N=41 Seneca Superior Lewis Green Klondike Parry 7
8 Strain analysis takeaways Seneca and Parry Sound highly distinct Lewis and Green lakes mostly distinct, some overlap with other groups Superior populations similar, likely polluted with Lewis Lake (especially Marquette) Klondike likely mix of Superior leans and humpers Genetic diversity similar among strains, slightly higher in Superior 8
9 Study design objective 2 Simulate pure and hybrid crosses 6 purebred crosses Eg. Seneca x Seneca 14 interstrain crosses Eg. Seneca x Green Identify ancestry of each individual Bayesian admixture (STRUCTURE) Determine classification thresholds 9
10 Genetic structure of simulated pure crosses 100% 50% 0% Seneca Superior Lewis Green Klondike Parry Seneca x Seneca Superior x Superior Lewis x Lewis Green x Green Klondike x Klondike Parry x Parry 10
11 Genetic structure of simulated interstrain crosses 100% 50% 0% Seneca Superior Lewis Green Klondike Parry Eg. Seneca x Green 100% 80% 60% 40% 20% 0% Green Seneca 11
12 Classification thresholds Determined iteratively based on results from simulated crosses Designed to maximize assignment accuracy to both cross types Pure: > 70% ancestry from single strain Hybrid: < 70% ancestry from single strain, classified based on top two contributions Reporting groups: Seneca, Parry, Lewis, Green, Superior (includes Klondike) 12
13 Assignment accuracy: simulated pure crosses Strain % correct Klondike 96% Seneca 98% Parry 97% Lewis 94% Green 91% Superior 75% Average 92% correct 13
14 Assignment accuracy: simulated hybrid crosses Strain % correct Klondike x Seneca 0.94 Klondike x Parry 0.92 Klondike x Lewis 0.89 Klondike x Green 0.89 Seneca x Parry 0.91 Seneca x Lewis 0.88 Seneca x Green 0.85 Seneca x Superior 0.83 Parry x Lewis 0.83 Parry x Green 0.81 Parry x Superior 0.8 Lewis x Green 0.78 Lewis x Superior 0.79 Green x Superior 0.81 Average 85% correct 14
15 Classifying pures and interstrain hybrids: takeaways Assignment accuracy of pure individuals > 90% for all but Superior (75%) Assignment accuracy of F1 hybrids 85% on average, most crosses between 80% and 90% Historic pollution of Superior strains with fish from Lake Michigan reduces accuracy Almost all pure and hybrid crosses identifiable with > 80% accuracy 15
16 Study design objective 3 Analyzed wild recruits to assess reproductive success of strains Received 1,030 Natural Recruits from Lake Michigan ( ) Removed 126 incomplete genotypes or contaminated tissues Removed 52 unknown sampling location Identified individual strain(s) of origin with STRUCTURE, hybrids counted as 50% each strain 16

31 Frequency of hybridization Genetic proportions Overall expected = 0.57, Overall observed =
32 Proportion of pures vs hybrids No major evidence F1 hybrids are highly unfit, some nuances Seneca hybrids frequent but similar to expectations Superior heavily stocked, pures rare 32
33 Conclusions Strains and inter-strain hybrids can be differentiated relatively well (SNPs may improve) Some variation in stock proportions across space, but Seneca usually dominant (exception: Traverse) Seneca is highly overrepresented compared to past stocking history, other stocks perform more poorly Performance of other stocks varies by area (e.g. Superior in North, Lewis/Green in Traverse) Hybridization rates similar to expectations based on genetic data (exception: Superior pures rare) 33
34 Management recommendations Continue stocking Seneca Clearly well adapted to Lake Michigan and successfully reproducing Continue stocking strains derived from Lake Michigan Possible adaptive advantages in certain areas (Traverse) Avoid putting all eggs in one basket, environment could favor remnant native alleles Evaluate reasons to continue stocking Superior strains Appears to be maladapted to many areas of Lake Michigan (sea lamprey, other factors?) but does well where mortality is low. Future: determine stock proportions of spawners to investigate survival vs reproductive success 34
