A study on the parasites (protozoan and metazoan) of freshwater crayfish (Astacus leptodactylus) in the Aras reservoir
Aras reservoir freshwater crayfish is an important economic fisheries resource of West Azarbaijan, Iran. This study was concluded to evaluate the prevalence of parasitic infestation of Crayfish in this area during different seasons of 2012. Among 390 different sizes of Astacus leptodactylus which were examined, arange of ectocommensals or ectosymbionts from a number of different phyla including 9 phylm and 11 class infested the different anatomic units of the surface and appendages such as gills, head , thorax, abdomen, walking legs, uropod, telson, antennae and antennulae of freshwater crayfish. Common groups such as peritrich ciliates, suctorian ciliates, free living nematodes, branchiobdellids, and Algae, copepods, rotifers and oligochaetes have also been observed in association with freshwater crayfish.

| Summary: | Aras reservoir freshwater crayfish is an important economic fisheries resource of West Azarbaijan, Iran. This
study was concluded to evaluate the prevalence of parasitic infestation of Crayfish in this area during different
seasons of 2012. Among 390 different sizes of Astacus leptodactylus which were examined, arange of ectocommensals
or ectosymbionts from a number of different phyla including 9 phylm and 11 class infested the
different anatomic units of the surface and appendages such as gills, head , thorax, abdomen, walking legs, uropod,
telson, antennae and antennulae of freshwater crayfish. Common groups such as peritrich ciliates, suctorian
ciliates, free living nematodes, branchiobdellids, and Algae, copepods, rotifers and oligochaetes have also been
observed in association with freshwater crayfish. |
