Morphological and molecular diagnosis of fungi associated with two species of carp (Cyprinus carpio) and shank (Tilapia sp.( in Karbala / Iraq

Abstract

The aimed of study was identifying the fungi associated two types of fish, carp (Cyprinus carpio) and the shank (Tilapia sp.) from freshwater fish in Karbala / Iraq.
