“…For the genus Cobitis ( S3 Fig ) the values of minimum genetic distance between its species ( S10 Table ) were among the highest for species of the same genus, meaning that these species were clearly separated. High values of interspecific genetic distance for the genus Cobitis have been observed in several studies [ 75 , 76 ]. The only exception are the species Cobitis hellenica Economidis & Nalbant, 1996 and Cobitis arachthosensis Economidis & Nalbant, 1996 for which the maximum genetic distance was 0.0070 and the minimum 0.0000.…”

DNA barcoding identification of Greek freshwater fishes

Biodiversity is a key factor for the functioning and efficiency of an ecosystem. Greece, though covering a relatively small surface area, hosts a great deal of species diversity. This is especially true for freshwater fishes. In recent years, the traditional methods of species identification have been supplemented by the use of molecular markers. The present study therefore aims to extensively produce DNA barcodes for Greek freshwater fish species and investigate thoroughly if the presently accepted species classification is in agreement with molecular data. A 624-bases long fragment of the COI gene was sequenced, from 406 freshwater fish specimens belonging to 24 genera and originating from 18 lake and river sites. These sequences were used along with 596 sequences from the same genera, recovered from BOLD, for the construction of phylogenetic trees and the estimation of genetic distances between individuals. In total, 1002 sequences belonging to 72 species were analyzed. The method was found to be effective for 55 of 72 studied species. 17 closely related species with low interspecific genetic distances were observed, for which further study is proposed. It should also be noted that, in four cases, cryptic diversity was observed, where groups originally identified as one species exhibited genetic distance great enough to be separated into discrete species. Region specific haplotypes were also detected within populations of 14 species, giving the possibility to identify even the geographic origin of a species. Our findings are discussed in the light of the rich history of the Balkan peninsula and provide a significant steppingstone for the further study of Greek and European freshwater fish biodiversity.

“…In Iran, the genus Cobitis includes Cobitis linea , C. avicennae , C. faridpaki (Mousavi‐Sabet et al, 2015) and C. keyvani as a junior synonym of C. faridpaki (Jouladeh‐Roudbar et al, 2017; Jouladeh‐Roudbar et al, 2020; Mousavi‐Sabet, Yerli, Vatandoust, Cevher Özeren, & Moradkhani, 2012). Actually, for a long time, spined loaches from the Southern Caspian basin were considered as C. taenia Linnaeus, 1758 (Abdoli, 2000; Abdoli & Naderi, 2009; Coad, 2021; Kiabi et al, 1999).…”

Reproductive biology of the endemic spined loach Cobitis faridpaki in a tributary of the Gorganroud River, Golestan province, northern Iran

Cobitis faridpaki is a small endemic loach from the southern Caspian basin. Reproductive parameters are key components for enlightening the life history of an endemic species. The reproduction parameters of C. faridpaki including sex ratio, spawning season, fecundity, and oocyte diameters were studied in a tributary of Gorganroud River – northern Iran, the area where no information on the Cobitis spawning is available, from February to July 2018. A total of 403 specimens including 47.8% males and 52.2% females were collected using electrofishing. Even though the sex ratio was not significantly different from parity, a perceptible dominance of females in the pre‐spawning and spawning periods could be observed in the population. Based on the monthly variation in GSI, the spawning period is from late March to early May. The absolute fecundity of females ranged from 57 to 1287, with a mean of 404 (±250) oocytes per ovary, and relative fecundity was estimated to be 47–386, with a mean of 136 (±73) oocytes per gram of total weight. Absolute fecundity established statistically significant linear relationships with total length and weight. Oocyte diameters varied from 0.26 to 1.30 mm, being of multi‐modal distribution throughout the spawning period, which suggests that the species is a multispawner. The oocyte size correlated positively with the length, weight, and age of mature females. This study provides fundamental information to aid in future conservation programs that intend to reduce the ongoing depletion of habitats and populations of endemic species.

“…T he genus Cobitis is one of the most widely distributed Palearctic freshwater fishes with 18 reported species from Turkey, including C. battalgili, C. bilseli, C. damlae, C. dorademiri, C. elazigensis, C. evreni, C. fahireae, C. kellei, C. levantina, C. phrygica, C. pontica, C. puncticulata, C. simplicispina, C. sipahilerae, C. splendens, C. strumicae, C. turcica and C. vardarensis [1][2][3][4]. A recent study on the spatial heterogeneity of freshwater fishes in the Mediterranean revealed that some populations of this genus are unrecognized species e.g.…”

A B S T R A C TC obitis fusunae is a new species described from the Sultan Marshes, Kayseri Province, Turkey. This species differs from the congener species of Central Anatolian basins by the combination of the following characters (none unique to the species): No black spot on caudal-fin base, having Z4 with dark-black stripe, pigmentation below Z4, merged Z1-Z3 postdorsally, 12-18 small mid dorsal blotches and one lamina circularis in males, two fixed, diagnostic nucleotide substitutions in the mtDNA COI barcode region, and a minimum K2P genetic distance of 5.4%.
