Helminth infections in common carp, Cyprinus carpio L., 1758 (Cyprinidae) from Kovada Lake (Turkey).
The aim of this study which was carried out from March 2003-February 2004 was to determine the parasites of carp (Cyprinus carpio L., 1758) inhabiting the Kovada Lake. During the study, a total of 63 common carps were caught in different regions of Kovada Lake each month and investigated parasitologically. In carps, the ectoparasite, Dactylogyrus minutus of Monogenea, was found and endoparasite...
We infer the phylogenetic relationships of finescale shiners of the genus Lythrurus, a group of 11 species of freshwater minnows widely distributed in eastern North America, using DNA sequences from the ND2 (1047 bp), ATPase8 and 6 (823 bp), and ND3 (421 bp) mitochondrial protein-coding genes. The topologies resulting from maximum parsimony, Bayesian, and maximum likelihood tree building method...

The name Pethia melanomaculata (Deraniyagala) is available for the Sri Lankan fish previously referred to P. ticto, being distinguished from its Indian congeners by the combination of the following characters; having ½4/1/3½ scales in transverse line on body; body depth 32.4-41.5% of standard length (SL); head length (HL) 26.1-29.2% of SL; snout length 25.3-35.6% of HL; eye diameter 24.4-31.9% ...
Rhodeus albomarginatus, new species, is described from the Lvjiang River, a tributary flowing into Poyang Lake of Yangtze River basin, in Anhui Province, China. It is distinguished from all congeneric species by unique combination of characters: branched dorsal-fin rays 10; branched anal-fin rays 10-11; longest simple rays of dorsal and anal fins strong and stiff, distally segmented; pelvic fin...
Divergent selection among environments affects species distributions and can lead to speciation. In this article, we investigated the transcriptomes of two ecotypes of scaleless carp (Gymnocypris przewalskii przewalskii and G. p. ganzihonensis) from the Tibetan Plateau. We used a transcriptome sequencing approach to screen approximately 250,000 expressed sequence tags (ESTs) from the gill and k...
Two freshwater fishes, Rasbora sumatrana (Cyprinidae) and Poecilia reticulata (guppy) (Poeciliidae) were exposed for a four-day period in the laboratory condition to a range of copper (Cu) and cadmium (Cd) concentrations. Mortality was assessed and median lethal concentrations (LC50) were calculated. LC50 increased with decrease in mean exposure times for both metals. For R. sumatrana, LC50s fo...
The slender shiner Pseudopungtungia tenuicorpa (Cypriniformes; Cyprinidae; Gobioninae) is an endangered freshwater fish species endemic to Korea. The current strategies for its conservation involve the study of population genetic characters and identification of management units. These strategies require suitable molecular markers to study genetic diversity and genetic structure. Here, we devel...
