摘　　要：The niche of the monogeneans,Dactylogyrus chenminjungae,D.curvicirrus and D.montshadskyi parasitic on gills of Culterichthys erythropterus, from Honghu Lake in Hubei province has been studied.The number of D.chenminjungae decreases successively from outer gill arch to inner gill arch.But there is no significant difference in intensity between the first gill and the second gill arch.No preference to gill arches of D.curvicirrus and D.montschadskyi has been observed.Spatial distribution patterns of the parasites indicate the effects of physical and chemical factors in microhabitat,the motility of individuals,intensity,reproductive strategy,and interspecific relationship.The niche breadth exends as the intensity increases.The niche of the monogeneans,Dactylogyrus chenminjungae,D.curvicirrus and D.montshadskyi parasitic on gills of Culterichthys erythropterus, from Honghu Lake in Hubei province has been studied.The number of D.chenminjungae decreases successively from outer gill arch to inner gill arch.But there is no significant difference in intensity between the first gill and the second gill arch.No preference to gill arches of D.curvicirrus and D.montschadskyi has been observed.Spatial distribution patterns of the parasites indicate the effects of physical and chemical factors in microhabitat,the motility of individuals,intensity,reproductive strategy,and interspecific relationship.The niche breadth exends as the intensity increases.
