In northern Canada, lake chub (Cyprinidae: Couesius plumbeus) have colonized a variety of thermal springs that differ substantially from the ancestral environment in both mean temperature and thermal variation. To examine whether this environmental change is associated with differences in physiological traits, we compared the thermal breadth, capacity for acclimation of thermal tolerance, and m...

Considering the importance of the myenteric plexus in fishes and the scarcity of data about it, research was undertaken with the purpose of contributing to the characterization of the myenteric plexus in fishes. The terminal segments of intestines of ten adult Cyprinus carpio underwent routine techniques of transverse histological sections of 6 and 10μm in thickness, stained with Weigert-Van Gi...

Research is ongoing to develop screening and testing programmes for endocrine disrupting effects of new chemicals and in the focus of this development are the fish test species common carp (Cyprinus carpio). In this study we have developed quantitative enzyme linked immunosorbent assays (ELISA) for VTS in common carp. The working range of the ELISA was 11.25 to 2000 ng mL(-1) (75-25% specific b...

During a survey of Gahar Lake and Gahar River from 2008 to 2009 some specimen obtained by seasonal sampling in 6 stations, 3 stations in the lake and 3 stations in the river. Three different methods were used for sampling, gill net and hook in the lake and electrofishing in the river. Due to the results 3 species from 2 families in Gahar Lake and 12 species form 3 families in Gahar River were...

ticularly in intensive aquaculture systems and display aquaria. These diseases are collectively referred to as “atypical mycobacteriosis” or simply “mycobacteriosis.” The term “fish tuberculosis” has been used in the past to refer to this group of diseases, but the term is not appropriate and should not be used. Tuberculosis is a very important disease of humans and mammals, but fish do not get...

A new nematode species, Rhabdochona kharani sp. nov., has been isolated from the intestine, stomach and swim bladder of the fish Labeo gedrosicus Zugmayer, 1912 (Fam. Cyprinidae: Cypriniformes) from spring water at Garruk, District Kharan, Balochistan. The new species is characterized largely by the presence of eight anterior teeth in the prostom, inconspicuous deirids, by the shape and length ...
