Three chitinase isozymes, HoChiA, HoChiB, and HoChiC, were purified from the stomach of the greenling, Hexagrammos otakii, by ammonium sulfate fractionation, followed by column chromatography on Chitopearl Basic BL-03 and CM-Toyopearl 650S. The molecular masses and pIs of HoChiA, HoChiB, and HoChiC are 62 kDa and pH 5.7, 51 kDa and pH 7.6, and 47 kDa and pH 8.8, respectively. Substrate specific...

Cranial spiking (CS) is among the most popular slaughtering methods for delaying rigor mortis progress of fish muscles. However, it may cause a convulsion (subsequently referred to as delayed convulsion), which undermines meat quality and taste. This study aimed elucidate mechanism underlying examine its influence on ATP consumption. Ten carps, nine tilapias, ten rainbow trouts, two ayus, three...

Large reef-associated predatory fishes play important roles in aquatic ecosystem along coast because of their ecological functions and economic values to recreational commercial fisheries. This study was carried out assess the function artificial reefs as alternative habitats for two common north Yellow Sea, China, Fat Greenling Hexagrammos otakii Korean rockfish Sebastes schlegelii.
