of spores of Kudoa genus representatives under unfavorable water salinity are
described for the first time.
29.5 Conclusions
The marine species of K. nova myxosporeans reflects negatively its cysts placing
into the fresh water, in which spores darken and deform with time, and sometimes
destruct themselves. In such spores polar capsules do not shoot out when submerged into alkaline solution, and disturbance of the darkened spores life activity is
observed. Location of spores in muscles placed into the fresh water softens negative
influence of low salinity and keeps number of anomalous spores at not high level,
like in the case of presence of such spores in the sea water. The best results in spores
preservation are observed in the sea water, placed in refrigerator.
Acknowledgment I am sincerely grateful to researcher of KGMTU (Kerch) O. E. Bityutskaya for
help in catching and transportation of fish, researcher of IMBR (Sevastopol) A. V. Zavyalov for
valuable support in choosing doses of antibiotics for conduction of experiment, researcher of
IMBR N. I. Babko for determination of water salinity in experiment.
