| Research Abstract |
Gastric digestion was studied in the isolated ex vivo stomach of rockfish. The digestibility of the ex vivo stomach was compared to in vivo and in vitro stomachs so that this technique could be used as a new artificial gastric digestion method. The digestibility was varied among groups(in vivo ; 68%, ex vivo ; 51%, in vitro ; 33%, respectively), however, the ex vivo technique appears a better digestibility than the artificial digestion using an in vitro test. These findings suggest that the ex vivo stomach should be useful in evaluation of fish gastric digestion, as a new artificial method.
