Abstract
For studying growth of sea squirt, Halocynthia roretzi, from laboratoy grown seeds, in situ culture experiment was carried out off Hansando located in the southern part of Korea from February 1984 to July 1986. In the growth of the mean body height, sea squirt grew up to 9.15 cm during the above period after they were seeded at about 0.05 cm. The meat weight of 1.27 g at the beginning increased to 41.69 g from February 1985 to March 1986. The decreasing tendency in body height, body breadth, total weight and meat weight of sea squirt was observed during the summer season in 1985 when the water temperature reached
