For this lab we were testing the effect of light on ghost shrimp activity.  We chose to study this  in particular about ghost shrimp so we could understand a little bit more on ghost shrimp activity.  It showed us both their normal life and then how it changes when they have more or less light.   To being in the lab we had 7 shrimp in a tank with just the normal room light, after observing them for three days we added a sheet over the top of the tank and only slightly lifting it to make observations we did this for three days as well.  

The Data:

Room Light:

12-9-14

-Shrimp are staying along the bottom.

-Seem to move around and not stay in one place.

 

12-10-14

-Climbing on rocks hanging out their not doing much.

 

12-11-14

-Moving around, looking through rocks.

 

Changed to Dark:

12-12-14

-  Staying around the ground not moving much (but they aren’t dead).

 

12-15-14

-Staying in one place running away from light.

 

12-16-14

-Staying in one place, not moving much.

 

   

 

    The main problem we ran into while doing this lab was the amount of time.  As a group we would have liked to put them through extreme light, but never got a chance to.  Next time I would either shorten the days we studied in each amount of light to be able to squeeze all three in the time allowed.

 

    In conclusion I found that our hypothesis was correct that they would be much more active in the light, but I wish we would have gotten a chance to test extreme light, but they enjoyed moving around and digging through the rocks throughout the normal light days, but seemed to not move much when they were put in the dark.  This lab taught me a lot about the behavior of an animal I didn’t know much about before we started.
