The content of cholesterol, total phosphatide and crude fat of the brains of 22 samples (from 0.867 to 732g. in weight) were estimated. The analytical results are shown in table 1.
The content of cholesterol of the brain have a tendency to increase with the body weight of carp, but there seems opposite tendency in the case of total phosphatide. Both sex and season of the sample has no influence on the content of cholesterol and phosphatide of the brain.
General analysis was carried on some of the carp brains and its result is shown in table 2.
