AbstractEndohelminths were investigated in seven species of fish, including six in the Schizothoracinae and one in the Coitidae in Lhasa River in Tibet of China in July 2004. A total of 9 species of endohelminths were recorded in addition to digeneans in the Allocreadium, including 3 species of acanthocephalans, i. e. Neoechinorhynchus qinghaiensis, Echinorhynchus gymnocyprii and the unidentified species Neoechinorhynchus sp. 3 species of nematodes, i. e. Rhabdochona hellichi, Contracaccum sp., Eustrongylides sp., 3 species of cestodes, i. e. Breviscolex orientalis, Ligula sp., Diphyllobothrium sp. Morphological characters of N. qinghaiensis, R. hellichi, B. orientalis, digeneans in the Allocreadium spp. and the unidentified acanthocephalans Neoechinorhyachus sp. were described. Specimens of Allocreadium could not be identified to species due to their morphological variations in different fish hosts of Schizothoracinae. Other helminths which use fish as intermediate hosts were also unable to be identified to species level. Since N. qinghaiensis and Allocreadium. spp. were reported in other species of fish in the Schizothoracinae, findings of the acanthocephalan and digencans in Lhasa River may Suggest that they be specialists in fish of the Schizothoracinae. 4 to 6! helminth species were found in the fish species examined in the Lhasa River, indicating a high species richness, with the exception of no single endohelminth parasite detected in Schizothorax oconnori. The Shannon-Wiener index for 5 species in the Schizothoracinae ( 0. 613 1 - 1.543 4) were much higher than in Triplophysa stenura (0.291 1. Similarities among the 5 species were relatively high (0. 173 2 +/- 0.230 3) - (0.375 1 +/- 0.275 8) whereas similarities between the Schizothoracinae and T. stenura were rather low (0.028 8 +/- 0.087 7) (0. 091 6 +/- 0. 161 8). In the present study, 4 allogenie parasite species which mature in final bird hosts were recorded,which may at least to some extent reflects the fauna composition in this high land area of Tibet.
