During the culture period from October 2010 to June 2011,
highest SGR was found at the fish farm station immediately after
the start of the experiment (October 13–28), showing 7.2±3.6%
(mean±SD, n=47). As the sea cucumbers grew, SGR at the fish
farm stations decreased and the growth stagnated after April, 2011
(Fig. 6a–c), when the water temperature attained 17 °C (Fig. 2). At
the control station, maximum SGR was found during the period of
October 28 to November 10, however, the growth stagnated after
February, 2011, then the weights decreased gradually after April
