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...

Assessments of the biological control potential of muddy loaches, Misgurnus mizolepis, were conducted against Aedes togoi, Culex pipiens pallens, and Culex inatomii larvae both in the laboratory and in small rice plots in Pusan, Korea, from June to September 1997. Medium-sized fish consumed almost all of 500 3rd-stage larvae of Cx. pipiens pallens offered daily in the laboratory. Predation by t...

The aim of the present study was to establish a protocol of sperm cryopreservation in Misgurnus anguillicaudatus and verify the applicability of the obtained protocol in other loach species. We evaluated the following parameters: inseminating dose, thawing temperatures (20, 25 and 30 degrees C for 10s), extenders (loach or cyprinid extenders), internal cryoprotectants (dimethyl sulfoxide (DMSO)...

Two distinct cDNAs encoding aquaporins (mmAQPs 1a and 3a) were isolated and characterized from mud loach Misgurnus mizolepis. The identified mud loach AQP cDNAs encode for polypeptides of 260 and 302 amino acids. Topology predictions confirmed six putative membrane-spanning domains connected by five loops and the Nand C-terminal domains being cytoplasmic. The mud loach AQPs 1a and 3a showed bro...
