Seasonal Changes of Biochemical Composition in Cultured Bivalves

양식패류의 생화학적 체성분의 계절적 변화

Seasonal changes in biochemical composition of Crassostrea giggas and Scapharca broughtonii in the Kosong bay and Kangjin bay, southern Korea were studied over 12 months in relation to their habitat. In Crassostrea giggas, protein was high during summer in all experimental station, but lipid and carbohydrate were high during winter, and no clear difference was between experimental station. Glycogen content was sharply decreased during summer, and energy content was low but carbohydrate was high during summer. In Scapharca broughtonii, protein was low, but carbohydrate was high during summer. Lipid was high from February to March, glycogen content was low from June to September. Energy content was low during winter and no clear difference biochemical composition was between experimental station of Scapharca broughtonii.

경남 고성만과 강진만에서 서식하는 굴과 피조개에 대한 체성분의 계절적 변화를 Station별로 조사 분석하였다. 굴의 경우 대체로 조사정점에서 모두 여름에 단백질의 함량이 높았으며, 겨울 동안 지질과 탄수화물의 함량이 높아 정점 간에는 뚜렷한 차이는 없었으나, Station 2에서 다소 양호한 상태를 나타내었다. 글리코겐의 함량은 여름에 현저히 감소하였으며, 에너지 함량은 11월부터 이듬해 3월까지 높은 값을 나타내었다. 한편 피조개의 경우 단백질은 여름 동안 낮았으나 탄수화물은 높게 나타났다. 지질은 2-5월 동안 높았으며, 글리코겐의 함량은 6-9월 동안 낮았고, 에너지 함량은 겨울 동안 낮게 나타나 어장간의 뚜렷한 차이는 없었다.
