Differential scanning microcalorimetry was used to assess the conformational stability of muscle lactate dehydrogenase (M4-LDH) from skeletal muscle of Misgurnus fossilis (loach) fishes adapted to low (the “cold” enzyme) and high (the “warm” enzyme) environmental temperatures. It was found that the denaturation temperature Td was the same for both forms of lactate dehydrogenase, whereas the den...

The dojo loach Misgurnus anguillicaudatus is an endemic freshwater species in Asia. effective conservation and molecular-aided selection of M. were limited without sufficient molecular markers. In this study, 112 novel single nucleotide polymorphism (SNP) markers screened based on 2b-RAD sequencing database, 56 SNPs them developed characterized by genotyping 40 individuals using SNaPshot method...

A disease outbreak occurred in June 2012 among mud loach cultured on pond farms in Jangseong-gun, Jeollanam-do, Korea. Mortality rates reached up to 1.2% in the farm per day. Typical clinical signs were bleeding ulcer at the middle portion of head and haemorrhagic erosion of the operculum. Based on biochemical characteristics, the causative bacterium isolated from diseased fish was identified a...

The osteological and myological structures of the cephalic region and pectoral girdle of the Asiatic catŽ sh Heteropneustes fossilis are described and compared with those of several other catŽ shes, as the foundation for an analysis on the phylogeneticrelationshipsof the genusHeteropneustes. Our observation and comparisons support a close relationship betweenHeteropneustesand the clariid catŽ s...

Teleosts which represent the most prominent and diversified group among actinopterygians, are interesting in many features particularly in their complex nervous system in terms of cytoarchitecture, hodology and number of neurons. Present study has been carried out to histoenzymologically map the caudal rhombencephalic nuclei of Heteropneustis fossilis by employing a modified histochemical techn...

Organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) were measured by a gas chromatography-mass spectometry (GC-MS) in some edible fish from Huairou Reservoir and Gaobeidian Lake in Beijing, China. The concentrations of OCPs and PCBs were higher in fish (except Misgurnus anguillicaudatus) from Gaobeidian Lake than in those from Huairou Reservoir. The average concentrations of H...
