Studies on Biochemical Characteristics of File-fish, Catherine modestus 1. Changes of General Components for One Year

말쥐치의 생화학적 특성에 관한 연구 1. 일반성분의 년간 변화

The ratio of the eatable flesh taken from the filefish and its chemical components were investigated from March 1980 to February 1981 and the results are as follows :1. The ratio of the eatable flesh taken from the fish was low during March to June and high during July to December. 2. The moisture content was $81.4-82.0\%$ during March to June, $77.5-80.1\%$ during July to December and $79.4-81.4\%$ during January to February. 3. The protein content was $15.4-15.7\%$ during March to June, $17.0-19.9\%$ during July to December and $16.1-17.0\%$ during January to February. 4. The Lipid content was $0.31-0.41\%$ during March to January, $0.46-0.84\%$ during July to January and $0.43\%$ during February. 5. The carbohydrate content was $0.3-0.4\%$ during March to July, $0.5-0.7\%$ during August to January and $0.3\%$ during February. In conclusion, the ratios of the eatable flesh taken from the filefish and its protein content were highest during July to December in one year.
