Histology and lipid accumulation of gibel carp normal liver and fatty liver. a Liver morphology of gibel carp. b Historical structure of liver tissues. The black column is scale bar (50 μm). c Number of hepatocytes on an area of 10 μm square. d ORO staining of liver tissues. Red color indicates lipid droplets. The black column is scale bar (50 μm). e ORO red pixels (X 105) in equivalent area. Asterisks stand for the significant differences between normal liver and fatty liver (**: p < 0.01). NL: normal liver, FL: fatty liver
