MicroRNAs (miRNAs) exert important roles in animal growth, immunity, and development, and regulate gene expression at the post-transcriptional level. Knowledges about the diversities of miRNAs and their roles in accessory air-breathing organs (ABOs) of fish remain unknown. In this work, we used high-throughput sequencing to identify known and novel miRNAs from the posterior intestine, an import...

The problem of osmoregulation in teleosts has been extensively studied by a number of workers to the effect that the basic plan of adaptive water and salt balance is figured out in its outline(Krogh, 1939; Baldwin, 1949; Black, 1951; Gaunt and Birnie, 1951; Fontaine, 1953, etc.). Several lines of evidences are available for physiological interpretation of observed osmotic phenomena in terms of ...

In dojo loach (<i>Misgurnus anguillicaudatus</i>), although most wild types are gonochoristic diploids that genetically differentiated into 2 groups, A and B, clonal lineages appear in certain localities. Clonal loaches have been considered to hybrid origins between the groups by a series of genetic studies. this study, using FISH with newly developed probe (ManDra-A), we identified...

A new species of nemacheilid loach, Triplophysa longliensis, is described from Yudonghe River, a small tributary of Pearl River in Guizhou Province, China. It can be distinguished from other valid Triplophysa loaches by the following combination of characters: body smooth and scaleless; head tapering; lips thin and smooth; posterior chamber of gas bladder highly developed, long, bag-shaped, tip...
