First records of the Vettonian spined loach Cobitis vettonica in Portugal with update on its Iberian distribution

occurrence of Ligula colymbi (cestoda) in spined loach (Cobitis taenia) and its effects on reproduction and growth of the host

The infection prevalence of Ligula colymbi plerocercoids in the spined loach Cobitis taenia inhabiting brackish waters of the Baltic Sea, and the effects of the parasite on the reproduction and growth of the host were studied. There was no significant trend in the infection rate among the different sampling dates in May–July. In total, 24.6% of females and 15.4% of males were infected. In most ...

Life history traits of the endangered Iberian loach Cobitis calderoni in the River Lozoya, Central Spain

European colonization by the spined loach (Cobitis taenia) from Ponto-Caspian refugia based on mitochondrial DNA variation.

In the last 20 years, new species, asexual reproduction, polyploidy and hybridization have all been reported within the genus Cobitis. An understanding of the current distribution and baseline phylogeographical history of 'true' nonhybrid Cobitis species is crucial in order to unravel these discoveries. In the present work, we investigated the phylogeography of the spined loach, Cobitis taenia,...

Age, reproduction and fecundity of the spined loach Cobitis taenia L. (Pisces, Cobitidae) from Lake Klawój (Poland).

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. ...
