| Samples were collected twice monthly by six replicates. In September 2009 collect a specimens of 208 snails belonging to two species (Bellamya bengalensis, Melanopisi costata) and 32 specimens of oysters belonging to the four species (Corbicula fluminalis, Corbicula fluminea, Pseudodontapsis euphraticus, Unio trigridis) of Kufa River, In September 2013 collect 558 specimens of snails belonging to the six species as record the appearance of four new species in the river are (Lymnaea auricularia, Melanoides tuberculata, Melanopisi nodosa, Turritella sp.) And 321 specimens of oysters belonging to five types as record the emergence of new species (Dreissena polymorpha) in Kufa River. As some environmental factors of the river in two years of the study was measured because of their effect on appeared and disappeared of organisms, as observed rise in pH and dissolved oxygen in 2013 than it is in 2009, and reduced temperature of the water and the Biological oxygen Demand and salinity | ||
