1. Read the thesis paper very carefully.
2. answer the professor questions and find more research to support the answers.
1. why did I choose 3-4 hours for food digestion, Is 3-4 enough to digest all the food in zebrafish?
2. Why did I choose 2 Zebrafish in each tank?
I belive 2 fish will make the change in Oxygen measurements more, and make the observation more accurate. Because One fish in a big tank can will make the measurement less accurate( support with evidences)
3. Is the measurement of 2 zebrafish is a good idea?why not 3 or 4 zebrafish?
I believe it will have the same effect, but to save the environment I will just use 2 zebrafish.( but find the evidence that 2 zebrafish is enough)
4. Does the size of the tank will affect the measurement of zebrafish?
