Effect of anoxic incubation on the oxygen uptake of Isoparorchis hypselobagri (Digenea: Trematoda).

Anoxic incubation for varying periods of Isoparorchis hypselobagri from the swim bladder of the catfish Wallago attu, led to an accumulation of oxygen debt on the part of the parasite. With increasing length of anoxic incubation, there is a corresponding increase in post-anaerobic oxygen uptake, and the longer the period of incubation is, the greater is the time taken to return to a normal rate of oxygen uptake.
