Fig. 6. Glutamine contents (µmol g^-1 wet mass tissue) in the muscle (white bars), liver (grey bars), gut (black bars) and brain (hatched bars) of the giant mudskipper, Periophthalmodon schlosseri during the subsequent 24 h period post-feeding. Values are means + S.E.M. (N=4), except for the brain (N=3). ^aSignificantly different from 0 h control, P<0.05; ^bsignificantly different from 3 h value, P<0.05; ^csignificantly different from 6 h value, P<0.05.
