SUITABILITY OF SHELLFISHES FOR PROCESSING 4. Suitability of Mussel for Processing

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 from December to May next year and revealed the maximum value, 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.
