Branchioblastoma in Sardinella longiceps is described in present study. Large tumour masses were found under the operculum. Tumour is characterized by the multilobed and pale to red in color and located in the brachial chamber of the fish. It varied in consistency from very soft and triable to hard and also vary in size from 17 mm to 33 mm in diameter and 18 to 44 mm in length. Prevalence study...

In a parasitic survey of the native and introduced fishes in the Zayandehrud River, 5 Myxobolus spp. were found in the gills, fins and skin of examined fish specimens. They include M. varicorhini from fin and M. samgoricus from skin of Capoeta damascina, M. musajevi from gills of Capoeta capoeta gracilis, Myxobolus cristatus from Capoeta aculeata, and M. saidovi from Alburnus sp. Data on the lo...

The Middle East contains a great diversity of Capoeta species, but their taxonomy remains poorly described. We used mitochondrial history to examine diversity of the algae-scraping cyprinid Capoeta in Iran, applying the species-delimiting approaches General Mixed Yule-Coalescent (GMYC) and Poisson Tree Process (PTP) as well as haplotype network analyses. Using the BEAST program, we also examine...

Neoechinorhynchus (Neoechinorhynchus) zabensis sp. n. (Acanthocephala: Neoechinorhynchidae) is described from Capoeta damascina (Valenciennes, 1842) (type host) and Capoeta trutta (Heckel, 1843) in the Greater and Lesser Zab Rivers, northern Iraq. The new species is unique among all other species of the genus by its characteristic paired para-vaginal muscular appendage and fragmented giant nucl...

growth and reproductive attributes were determined for capoeta damascina, an endemic fish species from west of iran. a total of 147 specimens of both sexes were sampled monthly from november 2008 to october 2009. the overall sex ratio was female biased. males were aged 0-4 years and females 0-5 years. the von bertalanffy growth parameters were estimated as; linf=34.81 cm, k=0.27 year-1, t0=-0.6...
