Kaganova N. Hematological criteria of Black sea bottlenose dolphins’ adaptation on various stages of their keeping in Oceanarium.

Simultaneous determination of the glucose level and number of eosinophils in the blood of bottlenose dolphins was used as a rapid test of differential diagnostic features of their adaptive responses to the conditions of captivity. This ensured the separation of the captured individuals in the population into groups with high, medium, and low stress resistance, plus a maladjustment group. The dynamics of dolphins' blood parameters during their three-month stay after being caught has become the basis of a scheme for selecting the dolphins with the best perspective for remaining. An increase in catalyse activity in the blood of adapted dolphins, a fall in the lipid per oxidation level and oxidative modification of proteins as the time spent in the aquarium increases shows evidence of the activation of their stress-limiting systems. This allows us to use the dynamics of these parameter as an indicator of the adaptational level of individuals to the conditions of existence in noogenic long-term existence.
