The fish attached the glochidia of this mussel are 5 species including Carassius carassius, Oryzias lapites, Pseudorasbora parva, Misgurnus anguillicaudatus, Channa argus. 2.

The infectious rates of glochidia were 82%, 40% and 18% in M. anguillicaudatus, O. lapites and C. carassius respectively. The average rate of these 5 species was 26.9%. 4. The number of glochidia attached to each fish were 26, 13 and 8 individuals in C. argus, P. parva and M. anguillicaudatus respectively. And the average number was 4.9 individuals. 5. The attachment parts on the fish were 42.1%, 29.4% and 10.9% in pectoral fin, caudal fin and dorsal fin, and also on the base of pelvic and mouth part.
