| Abstract: | The elimination dynamics of the sexually mature trematode Bunodera luciopercae, a specific parasite of the perch Perca fluviatilis L. was studied using three photoperiods (L: D; L: L; D:D). Permanent illumination induced the helminth to leave fish. The diurnal rhythm of elimination is not pronounced. High values were recorded both in the morning and in the evening. A 40-h elimination rhythm revealed for B. luciopercae is due to certain features of its life cycle. |
