1. Medaka Fish By: Jenna Knox Pd.3

2. The life Of Dexter Dexter was the Japanese Medaka fish that our lab group was given to observe and study. We received Dexter on April 8, 2011 and watched him hatch on April 19, 2011. The first day Stage 18

3. In the beginning The first thing we did was name our fish Dexter. We then placed the fish egg onto the microscope and looked at the forming fish inside. We recorded the stage that the egg was in and then took a picture. Day 4 Stage 30

4. A few days later Dexter grew extremely fast it was amazing. One day you could barely tell it was a fish and in like 2 days you could see everything coming together. The hardest part of this whole project was finding what stage the fish was in. The first day we got our fish it was in Stage 18

5. Different stages Day one Dexter was at stage 18 Day two Dexter was at stage 23 Day three Dexter was at stage 28 Day Four Dexter was at stage 30 Day Five Dexter was at stage 32-33 Day Six Dexter was at stage 35 The last day Dexter was at stage HATCHED!

6. Finally hatched The whole time we were looking at the Medaka fish I really wanted to see it hatched. But after it hatched I realized I was expecting more than what I saw. Even though I knew that the fish was very small I imagined that the fish would be pretty big after it hatched. It really wasn’t any bigger than the egg. Actually it was hard to see the fish in the water swimming around.

7. As first time parents I was really excited to watch a baby fish while it was growing inside of it’s egg. It was really exciting. Also I was proud because the fish survived long enough to hatch and didn’t die previous to hatching. I honestly thought that I was going to kill it when I put it on the slide or took it off. I was afraid to squish it or something along the line of that.

8. Scares!!!! One day when I was putting Dexter onto the slide he got stuck in the dropper. My heart sunk I thought, “This is it, I just killed our poor little fish.” But with the help of Shaylyn we got the fish out of the dropper and on to the slide.

9. What are these people doing to me? Honestly I felt bad for our fish. We had to flip him around and shove him in a dropper every day. If I were Dexter I would be thinking, “What the heck is this? An earth quake?” I think I would also be slightly dizzy.
