Abstract
It has been shown for the first time in experiment, that placing of marine species myxosporean Kudoa nova spores into fresh water influences negatively their construction and preservation in the case, when spores are in cysts, isolated from muscles and put to refrigerator. The percent of anomalous spores in these cysts at the 34-th day of experiment reached 87%, deformation or destruction of 48% of spores was observed already at third day. By 20-th day of experiment majority of spores and polar capsules darkened, polar filaments in such spores did not shoot being placed to 8% solution of KOH. If cysts of K. nova were placed into sea water and kept in the refrigerator percentage of anomalous spores made only 2–6%. But if the spores of the given myxosporean species were contained in muscle tissue and kept in waters of different salinity under natural weather conditions, then in the fresh water abnormal spores maximal share was of 17% and in the sea water – 20%.
