SURVEY OF CORRELATION BETWEEN INTERNAL INTESTINE HELMINTHES WITH SEX, SEASON AND SIZE OF MARINE FISHES (BRACHIRUS ORIENTALIS) IN NORTH OF PERSIAN GULF- ABADAN HARBOR

This study was conducted to identify intestinal helminthes parasites and Survey of correlation between this helminthes with sex, season and size of Marine fishes in North of Persian Gulf in Abadan harbor. The helminthes fauna is collected from body cavity and intestine of 100 specimens, Brachirus orientalis obtained from Abadan harbor were investigated during the year 2013-2014 .A lot of 4 species of helminthes were found in intestine and body cavity of examined fishes. The helminthes found was composed by 2 digenetic Trematodes (Lepocreadioides zebrine, Allocreadium brachirusii) all in adult state in intestine. A statistically significant correlation was observed between the fish parasites with sex and weight of fish in Lepocreadioides zebrine (P=0.03) and no significant correlation between the fish parasites with weight of fish in Allocreadium brachirusii, one nematode Hysterothylacium aduncum that the prevalence was23% the only cestod Protocephalus sp with 16%. Except Protocephalus sp which was reported previously often parasites species found in this study are reported for the first time from Iran. There is no significant correlation between the fish parasites with sex and weight of fish in Protocephalus sp (Sig>0.05).
