Abstract

換水量を連続して直接測定する装置で, 酸素飽和の状態において水温16.0±0.1℃でマナマコ, <I>Apostichopus japonicus</I>の換水を調べた。換水は, 一回の大きな呼出と複数回のほぼ等間隔に行われる吸入を一周期として行っていた。1換水周期での呼出時間は10.6±1.3sec/cycle, 呼出水量 (Vcy, ex) は95.5±20.0m<I>l</I>/cycle/kg, 一分間当たりの呼出回数は0.7±0.1stroke/minおよび一分間当たりの呼出水量は67.5±18.8m<I>l</I>/min/kgであった。1換水周期での吸入時間 (Tin) は79.5±26.3sec/cycle, 吸入水量 (Vcy, in) は95.8±26.4m<I>l</I>/cycle/kg, 吸入回数 (If) は10.3±2.9stroke/cycle, 吸入一回当たりの吸入量は9.8±1.8m<I>l</I>/stroke/kg, 吸入一回当たりの吸入時間は7.8±1.6sec/strokeであった。Vcy, inとVcy, exの関係は, Vcy, ex=0.27Vcy, in+69 [R<SUP>2</SUP>=0.12] あるいはVcy, in=0.48Vcy, ex+53 [R<SUP>2</SUP>=0.13] で表された。IfとTinの関係は, Tin=8.2If-4.3 [R<SUP>2</SUP>=0.84] , IfとVcy, inの関係は, Vcy, in=7.0Tin-27 [R<SUP>2</SUP>=0.61] で表された。

The ventilation in the respiratory tree of the Japanese common sea cucumber, <I>Apostichopus japonicus</I>, was examined under normoxic condition at 16.0±0.1°C using newly developed equipment which continuously measured the ventilation volume. One cycle of ventilation was composed of a large exhalation and several small inhalations. The duration of exhalation per cycle was 10.6±1.3 sec/cycle, the exhalation volume per cycle (Vcy, ex) was 95.5±20.0 m<I>l</I>/cycle/kg, the exhalation frequency per min was 0.7±0.1 stroke/min and the exhalation volume per min was 67.5±18.8 m<I>l</I>/min/kg. The period of inhalation per cycle (Tin) was 79.5±26.3 sec/cycle, the inhalation volume per cycle (Vcy, in) was 95.8±26.4 m<I>l</I>/cycle/kg, the inhalation frequency per the cycle (If) was 10.3±2.9 stroke/cycle, the inhalation volume per stroke of inhalation was 9.8±1.8 m<I>l</I>/stroke/ kg, and the duration of inhalation per the stroke was 7.8±1.6 sec/stroke. The relationship between Vcy, in and Vcy, ex was Vcy, ex=0.27 Vcy, in+69 [R<SUP>2</SUP>=0.12] or Vcy, in=0.48 Vcy, ex+53 [R<SUP>2</SUP>=0.13] . The relationships between If and Tin, and If and Vcy, in were Tin=8.2 If-4.3 [R<SUP>2</SUP>=0.84] and Vcy, in=7.0 If-27 [R<SUP>2</SUP>=0.61], respectively.
