Schizothorax prenanti is an endemic fish in the mountain rivers of southwestern China with unique protection value. To further explore the vortex motion of hydraulic habitats, which is closely related to the fish breeding process, the cross-sectional vorticity was used to evaluate the hydraulic conditions of the natural spawning habitat of S. prenanti. A coupled level-set and volume-of-fluid (C...

The infection status of Clonorchis sinensis metacercariae (CsMc) was examined in freshwater fish from a highly prevalent site, Wicheon (a branch of Nakdong-gang), which is located in Gunwi-gun, Gyeongsangbuk-do, the Republic of Korea. Total 1,162 fish in 32 species were examined by the artificial digestion method through 6 years. CsMc were detected in 720 (67.5%) out of 1,067 fish (26 spp.) and...

background: the breeding performance is an important parameter to evaluate the breeding success in captive condition. the optimum hormone dose in combination with latency period is desirable for getting best breeding performance in fish. objectives: the objective of the study was to find the spawning latency period in the hormonal induced reproduction of snow trout with two inducers (ovaprim an...

Dal Lake a Sub-Himalyan urban Lake is one of the most beautiful lakes of India and second largest in Jammu & Kashmir. Intensive farming practiced in the surrounding area of Dal Lake and its floating gardens leads to an enhanced vulnerability of crops to pests and indiscriminate use of pesticides. Possible transfer of these hazardous molecules from vegetable fields to the aquatic environment of ...

The Qinghai-Tibet Plateau (QTP) is a biodiversity hotspot, resulting from its geological history, contemporary environment and isolation. Uplift of the QTP and Quaternary climatic oscillations are hypothesised to have influenced the genetic diversity, population structure and dynamics of all QTP endemic species. In this study, we tested this hypothesis by assaying variation at two mitochondrial...

The schizothoracine fishes, members of the Teleost order Cypriniformes, are one of the most diverse group of cyprinids in the QinghaieTibetan Plateau and surrounding regions. However, taxonomy and phylogeny of these species remain unclear. In this study, we determined the complete mitochondrial genome of Schizopygopsis malacanthus. We also used the newly obtained sequence, together with 31 publ...
