Measures to calculate gill surface area (number of filaments (a), average length of filaments (b), total length of filaments (c), average space between lamellae (d), hemibranch area (e) and number of lamellae (f)) of swim-trained and control dwarf (white circle) and normal (black circle) Lake Whitefish. The effect of treatment, ecotypes and/or their interaction are noted when P-values < 0.05. NS was noted when no significant differences were observed
