Life-history
Overall, life history parameters did not differ among lake trout groups
grouped by fatty acid composition, including length-age models (Fig. 3;F 9, 63 = 1.58; P = 0.141). With the giant
sub-set included, growth differed between only between Group 3 and Group
4 (F 3, 41 = 3.958; P = 0.014), but not
between any other pairs (P > 0.1). Without Giants included
(prevalence of Giants was higher in Group 3 than Group 1, Group 2, and
Group 4), none of the pairs differed for length-at-age (P >
0.1), suggesting growth rate similarities among groups.
