1.1. Total lipid and cholesterol concentrations in hepatopancreas, gonad and muscle were analyzed for 70 blue crabs.2.2. The concentrations were highest in hepatopancreas, then gonad, and muscle was the lowest.3.3. In male crabs, the concentrations decreased from the immature stage (feeding and growth stage) to the mature stage (breeding stage), and from August to September (breeding period) in mature males.4.4. In female crabs, the concentrations were comparatively high for peelers (pre-molting stage) and mature females in October (pre-spawning migration period).5.5. The total lipid and cholesterol concentrations were significantly, positively correlated in both sexes.6.6. The total lipid and cholesterol concentrations were independent of both body weight and tissue weight. Exceptions were the immature females whose concentrations in hepatopancreas were negatively correlated with both body weight and hepatopancreas weight, and the mature females whose concentrations in gonads were positively correlated with gonad weight.
