English Abstract

In the present study, a new record for the M.

nipponense Samples collected by a network with a radius of 30 cm for the period from August 2014 until July 2015 of three stations in the Al-Kufa River, the first station is located north bridge Imam Ali and the second near the trocar Nissan , The third leg near the old Kufa bridge , Study the effect of environmental factors on the presence and the spread of shrimp river M.

nipponense which belong to the Order Decapoda , The highest density of shrimp river (63.58) individual / m3 at the first station in the October month and disappeared in all study stations.

in January month and February month .

Lower and upper limits for water temperature (13 - 30.4) C0 , pH (6.8 - 9.6) , dissolved oxygen (2.9 - 9.1) mg / L , electrical conductivity (1162-2055) µs/ cm and salinity (0.7 - 1.31) ppt, total hardness (210 – 930) mg / L and calcium ion ( 119 – 380) mg / L.

Environmental measurements showed that there is a positive correlation between shrimp river density and all of the water temperature , dissolved oxygen,the electrical conductivity, salinity and calcium ion relationship, also found an inverse relationship between the shrimp river density and all of pH and total hardness.
