Abstract

The physiological effect of a shallow water stressor was tested on normal diploids, meiotic diploids, heterozygous and homozygous clones of the ayu, Plecoglossus altivelis, in order to reveal potential physiological differences between the genetically manipulated groups. We measured the stressor effects on the hematocrit, leucocrit, hemoglobin, plasma glucose and mean corpuscular hemoglobin concentration and used replicas of the abovementioned fish groups as non-stressed controls. We found non-significant differences between the normal diploids and the genetically manipulated groups in 73% and 60% of the comparisons within non-stressed and stressed groups, respectively. Overall, a significant stress response was detected in 65% of the cases and was mainly characterized by alterations of the hematocrit, hemoglobin and plasma glucose levels. The expected reduction of the variation in the measured traits of the clones, in comparison to the normal diploids, was most prominent in the heteroclones.
