Abstract Identifying, evaluating, and prioritizing freshwater systems for conservation is a persistent challenge managers tasked with recovery of native fishes. We used historical records from the Gila River basin, national hydrography data set, Random Forest modeling to predict probability Spikedace Meda fulgida Loach Minnow Rhinichthys cobitis occurrence throughout their range in basin. Model...

Abstract We have analyzed the polymorphism of ISSR fragments DNA by polymerase chain reaction in spined loaches for first time. The analysis has made it possible to successfully differentiate genomes, which were presumably involved formation polyploid forms hybrid origin: Cobitis taenia ; from Danube River basin, are diagnosed as C. elongatoides tanaitica Don basin and Lake Sinoe, also assigned...

Mitochondrial DNA cytochrome b sequences (1140 bp) in 61 specimens of Chinese spiny loach Cobitis sinensis from 12 drainages in Taiwan were identified as two major clades, exhibiting a southern and a northern distribution, north of TzengWen and south of TzengWen (including TzengWen), respectively. The divergence time between these two phylogroups was estimated at 7.34-9.06 million years before ...

One thousand three hundred seventy three fish specimens of eight different species from the vicinity of Kyiv, Ukraine, were examined for the presence of trypanosomes and 921 individuals were found to be infected. The prevalence of infection ranged from 24% in freshwater bream, Abramis brama (Linnaeus), to 100% in spined loach, Cobitis 'taenia' Linnaeus. The level of parasitaemia also varied sig...

This is the first study concerning the features of the reproduction process of the karyologically identified spined loach C. taenia (2n=48). The histology of 71 ovaries, and gonadosomatic index (GSI) of karyologically identified spined loach Cobitis taenia L. from Lake Klawój (Northern Poland) were examined. The absolute and relative fecundity of 25 females was estimated by gravimetric method. ...
