가공적성을 판정하기 위한 기초자료로서 진주담치의 년중 월별 비만도와 화학성분을 분석한 결과는 다음과 같다. 1. 비만도는 $12~4$월이 높았다. 2. 글리코겐은 $12~5$월까지는 $2.7~3.9\%$로서 비만도의 지표인 F값과 G값이 높은 $12~3$월 사이에 높았고, F값과 G값이 가장 높았던 3월과 12월에는 $3.9\%$로서 가장 높았다. 그리고 단백질 함량은 $7~8$월에 가장 높았다. 3. 비만도 및 화학성분 측정결과로서 가공적성을 판정한다면 가공원료로서 여수 연안의 진주담치 채취적기는 $12~4$월 및 $7~8$월이라고 볼 수 있다.
This study was attempted to establish the basic data for evaluating the processing suitability of the mussel, Mytilus edulis, cultured by hanging method in Yeosu Bay, Korea. Seasonal variations in condition index and chemical .composition of the mussel were carried out from March 1978 to February 1979. The results are as follows: 1. The condition index was highest from December to April next year. 2. The glycogen content of mussel was 2.7 to $3.9\%$ from December to May next year and revealed the maximum value, $3.9\%$ in December and March. F and G-values as the condition indices of the mussel showed also the highest value from December to March. 3. The protein content of mussel was highest from July to August. 4. By the results of condition index and chemical composition of the mussel, the suitable harvest season as raw materials for processing is determined to be from December to April next year and from July to August.
