Science Fair Project Proposal
How will Salinity Effect Brine Shrimp Growth
Purpose
The purpose of this experiment would be to determine how change in salinity levels would affect the size and growth rate of a Brine Shrimp. This project would be used to find out which Ph level has the best effect on the Brine Shrimp.
I became interested in this type of project when I attended Marine Biology at Central Campus. We learned a lot about the specific balance needed between an animal and its habitat. We often traveled over three hours to pick up loads of shrimp, from the Omaha Zoo, to feed some of our various aquatic animals. So I did some research on the different ways that you can raise the shrimp and how it affects them.
The information I gain through my research and experimentation with my project can be used to better culture brine shrimp so that they may be raised and developed more efficiently. This would particularly help people like the Omaha Zoo, and Des Moines Marine Biology class because they are also presently doing a lot of research with the Brine Shrimp. In the end, the experiment would help to find a way to raise the largest Brine Shrimp possible there for helping anyone who also has to feed fish.

Science Fair Brine Shrimp: The Effects of Salinity, and different foods on Brine Shrimp Growth
Purpose:
To design and conduct a laboratory investigation to determine how different factors may affect the hatching and development of brine shrimp eggs. How can you get the largest and healthiest Brine Shrimp possible?
Factors:
How would different salinity levels within reason effect the growth of the salt water species known as Brine Shrimp? Also what would happen if we added the factor of different food substances such as different Algae or man made food.
Additional Information:
Though the different food types would have to be monitored more closely because Brine Shrimp are always eating and are well known filter feeders. I have provided a list of what is healthy to feed them along with a range of possible salinity levels that would be safe to use for science fair.
The most common Brine shrimp is the Artemia and they are often used as live food for aquariums.
Through exstensive research I have found that the Artemia begins by the hatching out of a dormant cyst.
The cysts can stay in a dormant type state for many years as long as they stay totally dry. When the cysts are placed in salt water, they can rehydrate themselves and resume their development.
Other variables that are important would include but not be limited to:
pH light and oxygen. A pH of 7.5-8.5 is best. It can be lowered by using muriatic acid or increased with baking soda. A only small amount of light is necessary for hatching it is also beneficial to their growth. On average it will take the Brine Shrimp 7-8 days to grow hatch and mature.
Salinity: 33-38 ppt.
