Description
Three-spined stickleback, Gasterosteus aculeatus L., is a typical boreal species in the White Sea. They show considerable long-term fluctuations in population abundance, so since 2006 it has increased in 4,5-15 times in different places. Parasite component communities of G. aculeatus juveniles were investigated in Seldyanaya inlet with dense growth of Zostera marina. The juveniles (total number 215) were caught in August-September 2011-2015. There was significantly difference in parasite community during 2011-2015. The juveniles harbored 11 parasite species, 6 of them had interannual abundance differences (GLM, p<0,0001). Structure of parasite component community 2011 and 2012 were similar. In 2013 cestode Bothriocephallus scorpii (the core species for previous 2 years) were not found, in 2015 it's abundance decreased in 4 times in compare with 2012 and the hemiurid trematodes were absent. Absence of these parasites may be caused by desaltation due to prolonged rain showers provoked death of planktonic crustaceans (intermediate hosts of hemiurids). Abundance of trematode Podocotyle atomon increased 3,5 times in 2015 that may be caused by transmission intensification as a result of final host (stickleback) population growth.
