Abstract

Investigations on stress response intensity were carried out in two distant strains of common carp: scaled Danube wild and selected mirror strain. First stressing was a 3 hour transport in polyethylene bags followed by tagging and measurement. Stress response was measured by plasma cortisol and glucose concentrations. Mirror carp showed significantly (P=0.001) lower cortisol (166.8 ng/ml) and glucose (10.2 mmol/1) levels than the Danube wild carp (436.1 ng/ml and 13.1 mmol/1, respectively). Medium high correlation was found between the two blood parameters (r=0,427, P=0,001, n=61). High variance of cortisol level observed in both strains provides the basis for the selection of high and low responding individuals which can be artificially propagated by andro- or gynogenesis to develop highly inbred lines.
