Artificial breeding of Japanese pearl oyster, Pinctada martensii was carried out, following the culture method devised by Prof. T.

The development of larvae is illustrated in Figs. 1-9, Shell size at the time of unbo-deve-lopment was 90-110 μ in height and 100-110 μ in length. Settling occurred when larvae reached 170-200 μ in height and 200-250 μ in length. In thank No. c-1 with a capacity of 8, 000 litre, it was possible to obtain over 137 thousands of spat, 17.1 per cent of the number of straight hinge veligers set free at the start. The records of cultures are summarized in Tables 2-5.
