Abstract

酸素消費量は, 10~1月および4~6月の水温9.6~24.2℃の間ほぼ一定で, 有機質重量比の小さい2~3月に著しく小さい値を示した。しかし, 短時間で水温を上下させると, それに伴って変化した。低酸素下においては, 酸素飽和度を低下させても水温9.9℃では70.5%まで, 15.3℃では62.0%まで, 19.9℃では58.1%まで, 24.2℃では54.7%まで, 28.0℃では29.0%までほぼ酸素飽和の状態での値を維持していた。

In the sea urchin, <I>Hemicentrotus pulcherimus</I>, the amount of oxygen uptake (Vo<SUB>2</SUB>) was almost constant from September to June (9.6-24.2°C), except in February and March. In February and March, the ratio of organic matter weight to total body weight was the lowest in the year, but in other months the ratio was almost constant. However, Vo<SUB>2</SUB> increased with 3°C rise in the water temperature per hour interval and decreased with lowering of the water temperature. Under hypoxic conditions, until the oxygen saturation in water fell to 70.5% at 9.9°C, 62.0% at 15.3°C, 58.1% at 19.9°C, 54.7% at 24.2°C and 29.0% at 28.0°C, Vo<SUB>2</SUB> remained at the levels of the normoxic condition.
