Low density culture, (0.24-0.26ind./m2) of barfin flounder, in large sized aquaria was undertaken to establish a culture system for stable procurement of the fertilized eggs. Captured females spawned repeatedly for approximately one month, and the total number of spawned eggs during a spawning season was averaged between 85, 000 to 406, 000 per one female. Both fertilizing rate and hatching rate were high, 84-87% and 39-66%, respectively, and almost same as those from artificial fertilization using eggs within one day after ovulation. These results thus demonstrated the usefulness of this low density culture for stable harvest of a number of fertilized eggs with good quality. The spawning of the barfin flounders was estimated to occur from 10p.m. to 4a.m. in the aquaria based on the serial observation of embryonic development in artificially fertilized eggs.
