After gathering a great amount of data from my previous experiments and observations, the Professor decided to change the set up of the experiment. Instead of having two zebrafish in one tank (one male and one female), Dr. Dabrowski decided to follow the methods of another spawning experiment in the past; we began to have three zebrafish in each tank (one diploid male, one triploid male, and one female). We also decided to double the amount of tanks to increase the rate at which we get data. Since one person can't observe six tanks simultaneously, I received a new partner for the experiment: undergraduate student Kevin Fischer.
The protocol for observation was very similar to the previous weeks, so I was able to help introduce Kevin to the spawning observations we were looking for. Afterwards, we weighed and measured each fish. Then, Kevin and I would both check the fertility rate of each tank.
