Outline of Final Research Achievements	Large amounts of lipids are stored in oocyte of teleost fishes as essential energy and nutrient resources for developing embryos and larvae. However, little is known about the mechanisms underlying their accumulation and utilization in the oocytes. This study demonstrated that lipidic features of the oocytes and composition of lipoproteins, which is a principle carrier of neutral lipids, in Japanese anchovy and Black skipjack tuna as comparative models for marine teleost. Also, this study revealed that neutral lipids transport pathway into oocytes via very low density lipoprotein can be universal way to any teleost fishes.
