Abstract
Fish protein concentrate (FPC) and lipids were prepared from the muscle of the stromateid fish, Cubiceps gracilis, to investigate their nutritive effects on rats. The FPC wsa found to rather promote the growth of rats with the protein efficiency tatio 3.84, which is higher than that of casein, 3.26. The muscle lipid represented mainly by diacyl glyceryl ethers (DAGE's) showed a nutritional value comparable to that of cottonseed oil. The rats fed with a DAGE diet accumulated in their liver lipid detectable amounts of DAGE's which were similar in composition to those of the muscle lipid of C. gracilis.
