Table 3 Initial and final body lengths and masses and specific growth rates (mean ± SD) of lake trout from the Seneca lake and slate Islands strains of lake trout fed either the control or thiaminase experimental diet.

  1. Note. Length is expressed in cm, mass is expressed in g, and specific growth rate is expressed in % ∙ day− 1. Superscript letters denote homogenous subsets from a t-test analysis (see text). Differences in length, mass, and specific growth rate at experiment end were examined with linear mixed models that do not permit post hoc tests. Descriptions of differences are found in text. The diets were administered for 260 days.
