Morphometric, meristic and molecular (COI) characters of Alburnus zagrosensis, from the upper Karun River drainage in Iran, largely overlap or are identical with those A. sellal, a species widely distributed Qweik Persian Gulf basin, including drainage. As no character states could be found to clearly distinguish these species, zagrosensis should treated as junior synonym sellal.

The present study was conducted to provide a detailed descriptive osteology of Barbus cyri from Southern Caspian Sea for the first time and comparing it with those B. lacerta Tigris Urmia lake basins. For this purpose, twelve specimens were collected Safidrud River using electrofishing device fixed in 10% buffered formalin. Then, cleared stained alcian blue alizarin red osteological examination. A description features provided. Based on results, several differences observed between two...

In this study, the length-weight relationships (LWRs) and condition factors were estimated for 445 specimens belonging to three gobiid species viz. Ponticola bathybius (Kessler, 1877), Neogobius caspius (Eichwald, 1831) pallasi (Berg, 1916) from Southern Caspian Sea basin. Total length total weight of examined ranged 4.9-28.3 cm 0.64-263.4 g, respectively. The parameter b studied found between 2.47 (N. caspius) 3.45 pallasi) with r2 ranging 0.831 0.988. LWR K parameters are reported first...

Barbus urmianus from the Mahabad-Chai River in Urmia Lake basin, is distinguished its congeners B. lacerta group by a well-developed middle pad of lower lip, shorter postdorsal length (25.2–42.0 vs. 46.4–60.7% SL), long anal fin (11.0–23.0 6.0–10.4% short dorsal-fin base (9.2–15.6 16.1–22.6% less scales caudal peduncle (14–23 25–35), and 64–85 on lateral line (vs. 52–70).

This study reports the presence of genus Cobitis in Zarrineh River, Urmia Lake basin, Iran. Its taxonomy is clarified and zoogeography basin discussed. provides morphological characteristics, mtDNA COI barcode sequences collected specimens analyses phylogenetic relation within members this The results revealed that morphometric molecular (COI) characters are largely overlapping or completely identical with those saniae Eagderi, Jouladeh-Roudbar, Jalili, Sayyadzadeh et Esmaeili 2017....

Taxonomic status of six populations the Gobiids (Teleost, Gobiidae) in southern Caspian Sea basin using COI gene

Kura bleak, Alburnus filippii, a member of the family Cyprinidae, is found in rivers Aras and Sefidrud, Anzali lagoon Iran.The current study was conducted to provide detailed osteological description this species since there not adequate information regard.In order attain goal, 20 specimens were collected from Ahar Chay River by electrofishing device, fixed 10% buffered formalin.The cleared, stained with alizarin red S alcian blue for examination its skeletal structure provided.The results...

The osteological characteristics is an important tool for clarification of the phylogenetic statue family Nemechelidae. Since any information available about features genus Turcinoemacheilus , hence present study provides a detailed hafezi as representative this genus. Ten specimens T. were collected from Shalamzar Stream, Tigris basin, Iran and cleared stained examination. According to results, osteologicaly characterized by absence preethmoideum-I postcleithrum, having four basibranchials,...

This study was carried out to provide a detailed osteological structure of the newly described crested loach, Paracobitis persa . For this purpose, ten specimens were collected from Malsosjan spring, in Kor River basin and fixed 5% buffered formalin. After clearing staining, their skeletal examined. The results compared other members family Nemacheilidae particularly P. hyrcanica iranica Based on results, can be distinguished by combination characters, including having lacking sesamoid...

This study was conducted to compare the morphological characteristics of Ponticola iranicus populations from Anzali Wetland drainage (wetland and it's two draining rivers, namely Siahdarvishan Pasikhan, Southern Caspian Sea basin). For this purpose, five specimens P. Pasikhan River, ten Siah-Darvishan eight were collected. After anesthesia, fish fixed into 10% buffered formalin transferred laboratory for further study. A total 22 morphometric traits measured using a digital caliper. The...
