| Outline of Final Research Achievements |
In the processes of aquaculture, seedling production often faces mass mortality of developing fish. Although developing fish should metabolize various nutrients, limited knowledge is available regarding this topic. We focused on transcription factors normally found in adult livers and assessed their expression in developing zebrafish. Some of the transcription factor genes were expressed in zebrafish embryos, and their expression levels were changed in response to stressors, such as low oxygen, low temperature, low pH. These results suggest that developing fish embryos and larvae have abilities to adjust their metabolism to cope with external stresses.
