The examined teleost fishes were six species of Cottida, seven of Percida, one of Anguillida, one of Pleuronectida and one of Notacanthida. These sixteen species were caught from 300-500m depths. The component fatty acids of the neutral lipids in flesh, viscera, liver and gonad of the examined fishes were determined by gas-liquid chromatography. The results showed that the component fatty acids in liver consisted of large amounts of monoenoic acids, and small amounts of polyenoic acids. A similar tendency was also recognized in the case of the flesh of five species and the viscera of six species. The ratios of monoenoic acids to polyenoic acids in the component fatty acids of the liver were above 4. It was thought that this indicates a characteristic fatty acid composition in the neutral lipids of deep-sea fishes.
