The authors determined the general chemical components of the ascidian, Cynthia roretzi V. DRASCHE collected at the Onagawa Bay in Miyagi Prefecture. The results obtained were as follows: 1. The height, width, total weight, test weight, muscle weight and viscera weight of the ascidian were 4.5-13.4cm, 2.7-8.lcm, 17-195g, 11-139g, 3-50g and 2-21g, respectively, (Table 2). 2. The contents of moisture, crude protein, crude fat, crude ash and glycogen were 75.12 ± 1.61%, 9.36 ± 0.85%, 2.35 ± 0.41%, 1.65 ± 0.21% and 11.56 ± 1.42% in the muscle, and 78.31 ± 1.64%, 13.19 ± 0.87%, 3.19 ± 0.44%, 1.75 ± 0.41% and 3.52 ± 0.93% in the viscera, respectively, (Table 3). It should be remarked that the ascidian contained a large amount of glycogen compared with other marine invertebrates such as mollusca and crustacea.
