1. Speaker: 21723 Ching-Po Huang Teacher:??? Effects of physical environmental change on Zebrafish and the Paradise fish’s breeding

2. ∙Objectives ∙Materials ∙Experiments ∙Discussion ∙Acknowledgement

3. Experiments are designed to measure the number of the embryos hatched after the physical environment for breeding (that is, the aquarium wall) change. The study will help us determine whether the breeding of the embryos is affected by the breeding environment. Objective

4. Zebrafish (Danio. rerio) Paradise fish (Macropodus. opercularis) Aquarium Plastics corrugated board Glass Acrylic Sandpaper Power supply Aluminum foil Materials

5. Experiment 1: Colors of the walls affected the number of hatched fish

7. Experiment 2: the change of materials affect the number of hatched fish

9. ※ The result will be continued. (mesh number: 60#, 100#, 150# and 220#) Experiment 3: The textures of the walls affect the hatching process

10. ※ The result will be continued.

11. Questions remain whether the differences in the number of hatched fish is significant enough for me to claim that changes have an effect on the breeding pattern of the fish.
