The seasonal fluctuation of the plasmodia ofMyxobolus gibelioiWu et Wang, 1982 in the gill filaments of the allogynogenetic gibel carpCarassius auratus gibelio(Bloch) in a fish pond in Hubei Province of China was investigated from August 1999 to July 2000. A total of 445 fish was examined; the overall prevalence of the plasmodium infection in the fish was 64.94% and mean abundance of plasmodia was 11.65 ± 27.85 (mean ± SD). Significant seasonal changes in prevalence and mean abundance, with higher levels of the plasmodia infection from late spring to autumn, were observed.
