Strongylocentrotus intermedius is the most important species for production of uni in Japan and China. Demand has exceeded supply from fisheries as stocks have been depleted and field culture is limited in production. This had led to interest in on‐land aquaculture as a potential source to increase production of uni. Studies have shown culture on land is feasible and that formulated feeds support gonad production. This paper reports high gonad production (gonad indexes of 35) using dry formulated feeds that exceeds maximum indexes for S. intermedius in the field and equals that reported for raft culture. The availability of a dry formulated feed that is effective in production of uni increases the potential for land‐based aquaculture of S. intermedius .
