In this study, two new freshwater fish species, Gambusia holbrooki Girard, 1859 and Petroleuciscus borysthenicus (Kessler, 1859) were reported from Simenlik-Akgöl Lagoon in Yeşilırmak Basin (Samsun). Turkey has a rich biodiversity terms of fish. Because climate change, periodic ichthyofauna monitoring updating fauna are critical. holbrooki, Eastern mosquitofish, is an invasive species widesprea...

Tributaries of the Colorado River Basin, historically home to a complex of endemic omnivores collectively referred to as the ‘three species’; flannelmouth sucker (Catostomus latipinnis), bluehead sucker (C. discobolus) and roundtail chub (Gila robusta), have experienced the establishment of numerous non-native fish species. In this study, we examine the impacts of the trophic ecology of non-nat...

The chromosomes of three species from the genus Leuciscus (the ide L. idus, the European chub L. cephalus and the common dace L. leuciscus) were examined with the FISH technique for 5S and 28S rDNA probes. The analysis showed that among the three examined species, 5S rDNA signals were located on two large and four small subtelocentric chromosomes in L. leuciscus, on one large and five small sub...

Model derived predictions of fish growth are frequently required for detailed investigations of population dynamics to inform management decisions. Simple growth models are typically fit to paired age and length data, but age data is often not available from endangered species because of restrictions on lethal or invasive sampling methods. Growth increment data from capture-recapture studies ca...

Black spot is a common disease syndrome of freshwater fishes. This study provides information on the rank of density of the black spot agent and opercular bone alterations associated with at least one digenean, Uvulifer sp., infecting native and non-native catostomids and cyprinids of the Upper Colorado River Basin. We evaluated the density rank of pigmented metacercariae and associated alterat...

Surgical site infection (SSI) is one of the complications which arises later on in the postoperative period with an incidence five to twenty times that of vaginal delivery. Knowing the prevalence of SSIs and its risk factors is importan...

In this study, the reproductive biology of chub population in Hafik Lake was investigated. 242 samples were caught between April and November 2009. The age of S. cephalus samples were found to range between I-VIII in addition, 153 of them were female and 89 were male. Their fork lengths changed between 114-332 mm, and body weights were between 22.5 and 550.3 g. Male specimens were dete...

To gain a better understanding of which pharmaceuticals could pose risk to fish, 94 representing 23 classes were analyzed in blood plasma from wild bream, chub, and roach captured at 18 sites Germany, the Czech Republic UK, respectively. Based on read across humans, we evaluated risks pharmacological effects occurring fish for each measured pharmaceutical. Twenty-three compounds found plasma, w...
