A total of 54 abu mullet Planiliza abu (Heckel, 1843) were collected from two stations (north and south stations) along the Euphrates River near Samawa City, Al-Muthanna province and were examined during the period from October 2016 till September 2017 for parasites. Six out of 35 examined fishes from the north station (17.1%) and one out of 19 examined fishes (5.3%) from south station were infected with the microcotylid Solostamenides paucitesticulatus Kritsky & Öktener, 2015. The parasite was illustrated and described, and it is considered as a new record for the parasitic fauna of fishes of Iraq.

The current study aimed to determine the morphometric and meristic characteristics of the North African catfish Clarias gariepinus (Burchell, 1822). Six specimens of C. gariepinus were collected from the Tigris River, in central Iraq. This study is considered the confirmation first record of this species in Iraq, and the second documentation of this exotic fish. The present species is characterized by a very long dorsal fin, a rounded caudal fin and four pairs of barbels.

   The Ciliophoran Trichodina magna Van As and Basson, 1989 is recorded for the first time in in Iraq from gills of the blue tilapia Oreochromis aureus (Steindachner, 1864) Iraq from Al-Graiat location on the Tigris River at Baghdad city. The description and measurements of this external parasite as well as its illustrations are given.

The monogenean Gyrodactylus lavareti Malmberg, 1957 is recorded here in the present study for the first time in Iraq from gills of the common carp Cyprinus carpio. This is the twentieth gyrodactylid species to be recorded from fishes of Iraq. The description and measurements of this parasite as well as its illustration were given.   
 

A total of 109 fish specimens belonging to six species (Barbus grypus, B. luteus, B. xanthopterus, Cyprinion macrostomum, Cyprinus carpio and Liza abu) were collected from Tigris river passing through Salah Al-Deen province during the period from September 2008 till January 2009. These fishes were infected with nine parasite species which included two sporozoans (Myxobolus mülleri and Dermocystidium percae), three ciliates (Trichodina cottidarum, T. elegini and T. murmanica) and four monogenetic trematodes (Dactylogyrus rhodeianus, D. vastator, Paradiplozoon cyprini and Microcotyle donavini). Among these parasites, two trichodinids (T. elegini and T. murmanica) were reported for the first time from fishes of Iraq. Also, B. grypus is c

Abstract The present work included morphological, anatomical, and palynological characters for the new species Acaalypha australis L. specimens, which belong to the family Euphorbiaceae. The species recorded in the study for the first time in Iraq. The plants of this species are annual herbs with green, striated or sub – polygonal stem, and branched near bases, Leaves are simple spirally alternate and lanceolate in shape. Flowers are unisexual, arranged in the axial of distinct leafy and cordate bracts, female flower arranged at the bracts bases and each flower with trileafed perianth and superior ovary with trilobed stylar stigma which has dense and coiled stigmatic hairs. Male flowers are arranged as a mixed verticellate inflorescence a

This study presented the first recorded of the banded garden spider Argiope trifasciata and    described for the first time in Baghdad city, Iraq. The specimens were collected from Al-Rashidiya sub-district north of Baghdad city on 26/ November/ 2021 (7:00 am- 6:00 pm) from fruit gardens (orange and apricot trees) and agriculture lands (palm trees, crops of wheat and vegetables). The spider "Argiope trifasciata" species is a member of the orb-weaving spider genus. It belongs to the Araniedae family, widespread worldwide, and has four pairs of long legs covered with spines and eight eyes arranged in two rows. The females of Argiope trifasciata spiders are yellow and covered with silvery and shiny hairs on the

 The present study aimed to estimate percentage of red and white muscles fibers in two species of bony fishes belong to two different families which represented by Tenualosa ilisha (Hamilton , 1822) that belongs to the family Clupeidae and Cyprinus carpio (Linnaeus , 1758) that belongs to the family Cyprinidae . The samples were collected from local market at holy Karbala province. The results show difference clear in mean values of muscles numbers at different studied length groups, and the percentage of red muscles fibers were less than that of white muscle fibers at different body regions (R1,R2,and R3) among species.  The total average of red muscle fibers values ranged between (4.23 - 11.08 %) while the total average of wh

    A survey of fish species in the Iraqi marine waters was carried out for the period from November 2014 to March 2018. The list included 214 species representing 75 families.

     The family Carangidae dominated the marine fishes in Iraq, which was represented by 24 species, followed by Haemulidae with 11 species, and then Serranidae and Sparidae with nine species for each, while 34 families contained a single species only.
