English Abstract

The present study was conducted on ten species of carangid fishes : Alectis indica, Alepes djedaba, Alepes kleinii, Atropus atropos, Atule mate, Carangiodes armatus, Carangiodes bajad, Carangiodes malabaricus, Gnathanodon speciosus and Megalaspis cordyla, which were collected from Iraqi marine waters north west the Arab Gulf. As a total 600 fish were collected during the period between September 2011 to March 2012.

Fishes were stored in plastic boxes filled with small ice pieces and brought as soon as to the laboratory in Department of Fisheries and Marine Resources, College of Agriculture, University of Basrah, for examination.

The first part of the study included gross and microscope examination of the internal organs of fish, where the results showed nine different species of parasites, five species of trypanorhynch cestodes (larvae) Callitetrarhynchus gracilis, Callitetrarhynchus sp., Floriceps minacanthus, Progrillotia sp.

Pseudogrillotia spratti.

And one species of larva nematode Skrjabillanus sp.

and three species of copepods Lernanthropus indicus, L.

corniger and Caligus cordyla, taxonomical features and measurements of each parasites were given.

All these parasites were recorded for the first time in Iraq in carangid fishes and considered as a new host except C.

gracilis have been registered. All the specimens were put in the British Museum of Natural History as a voucher specimens after it had been confirmed by : Dr.

Geoffrey A.

Boxshall who confirmed a classification of crustacean, and Prof.

Dr.

Harry Palm and Dr.

Eileen Harris who confirmed a classification of trypanorhynch larvae. The second part of the study included identifying a histopathological changes which caused by Lernanthropus, Caligus and trypanorhynch cestodes.

It was found the macroscopic lesions represented hemorrhage, congestion, patches and redness around the gills and internal organs (Spleen, heart, liver, stomch).

The microscopically showed that thickening in the primary lamella and the presence of foreign bodies may be from parasites, with acidophilic materials aggregation.

Infiltration and dilation of blood vessels were found around the heart area. The third part included estimation of protein contain from Callitetrarhynchus gracilis (0.029 mg / ml.),and use electrophoresis technique by SDS to found the molecular weights of proteins from C.

gracilis, and the results showed that three bands of protein with molecular weights ranged between 4-19 Kilodalton.
