*CZ = Czech Republic, HU = Hungary; ^†Data related to pre-screening of all ponds: based on PCR (infection prevalence) and visual examination (infection intensity); intensity refers to infected fish only, estimated in kidney smears rated 0–5 on basis of the percentage of renal tubules containing parasite stages and their degree of filling (a-small numbers of parasites, b-large sections of tubules filled with parasites, c-lumen of tubules widened by masses of parasites): 1 = 1-8%/a, 2 = 9-16%/a, 3 = 17-23%/b, 4 = 24-39%/b, 5 = 40-79%/c; ^‡At least 15 fish per month; sampling conducted 2011–2013.
