In nutritional physiology, the accumulation and consumption of body fat in fish have been linked to serum lipoprotein. In order to evaluate this relationship, the serum lipoprotein variation and the seasonal changes in fat contents in cultured red sea bream were examined and related to their growth. As fish grew bigger, the fat contents increased from summer to winter, and decreased from winter to spring. The VLDL and LDL disc electrophoretic profiles were dark for the increased fat contents, and light in the other season with decreased fat contents. This suggests that VLDL and LDL are involved with body fat accumulation. The disc electrophoretic profiles for HDL_2 were hardly found during the increased fat contents seasons, but these were more evident during decrease seasons. Therefore, it is thought that the appearance of HDL_2 can be related with a lowered body fat contents, as a result of seasonal change. It can be concluded that the HDL_2 is solely involved with consumption of the accumulated fat.
