Checking metaserker Postodiplostum distribution in Alburnoides eichwaldii in the Zaringol River of the Golestan Province

Metaserker of Postodiplostum kuticula is of common parasites in many fishes.Intermediate hosts of the parasites are snails and final hosts are birds. Metaserker,which is often in black cysts, is seen on the sub-epidermis of the skin, and can beseen on the fins. Metaserkers produce black seeds which are often dangerous for fries.Metaserker fitness on the host is called topographic feature of parasite. At the presentstudy, 66TAlburnoides 66Teichwaldii from the Zaringol River Zarin of the GolestanProvince were examined for the distribution of cysts. 100 samples of 66TA. bipunctatus66Twere randomly caught using a seine net 6Twith5T6T 5T6Ta mesh size of 2 mm6T, and for a closerlook, they were transferred to the laboratory. To compare the topographiccharacteristics of the contamination of the Metaserker of Postodiplostum, in thisspecies, the numbers of black spots on each fin separately, and also in the head, upperand lower half of the body were counted. Metaserker severity of the infection, theseverity of the infection of Metasker among the infected fish were calculated.Significant difference between the numbers of cysts in areas were examined using anANOVA and SPSS16. The total average number of black spots in the species 66TA.66Teichwaldii was 3.29 ± 6.94. Also, in this species (66TA. 66Teichwaldii), most polluting wereobserved in upper limbs, which was significantly greater than the lower half(P<0.05).
