Two sea urchins, Strongylocentrotus nudus and S. intermedius are recently being caught as animals of economical importance in Hokkaido. According to Kinoshita (1958), their animal has amounted to as much as about 7,000 tons in average from 1953 to 1957. To know the spawning habits of these animals supplies not only one sort of interesting information on their life-history from the biological viewpoint, but also an important part of the basic information on the sea urchin fishery. Such information includes such items as the gametogenic cycle, spawning season and size at first maturity. Among the studies dealing with the spawning habits of Echinoidea are those by Miller & Smith (1931), Tennent, Gardiner & Smith (1931), who illustrated...
