Gas content of swim bladder of Wallago attu and oxygen consumption in Isoparorchis hypselobagri (Trematoda)
Tóm tắt
The swim bladder gas of Wallago attu contains O2 (22–58 mm Hg) and the presence or absence of Isoparorchis hypselobagri does not influence the O2 content of the swim bladder. Glucose increases the O2 consumption of I. hypselobagri by 50%. With the passage of in vitro culture time, the rate of O2 consumption gradually decreases to the extent of 64% on the 40th day. The optimal temperature for O2 consumption is 30° C beyond which the rise in temperature is detrimental to the fish trematode as manifested by the decrease in their O2 consumption.
