Introduction:
To observe the hatching and the survival of Artemia in different water salinities
Objective:
- Genus of aquatic crustacean known as the 'Brine Shrimp'
- Two types of eggs: thin-shelled eggs and thick shelled eggs
- Food source for fish
- Live in salt lakes
- Almost never found in open sea areas
- Optimal conditions:
- 15~35 ppt salinity
- Highly oxygenated water
- Temperature of 25~28 degrees Celsius
- Water pH of 8~9
Experiment Information:
Conditions of test Environment:
Variables:
-Semi Controlled ( Natural environment conditions reproduced in a container)
Physical:
- Temperature at 28 degrees Celsius
- Illuminated 24/7 for the whole experiment
Chemical:
- pH of 8~9
Hatching- Brine Shrimp eggs
Perception- Sight
Growth and Development/ Survival: Counted using grid method
Parameters Used:
Effects of Water Salinity on the Hatching and the Survival of Artemia Salina
Hypothesis?
Prediction:
Optimal hatching salt concentration is 15 ppt
# of brine shrimps in 35ppt
# of brine shrimps in 10ppt
# of brine shrimps in 15ppt
# of dead brine shrimps in 10ppt
By Annes Yoo-Jin Kim and Marie-Sara Savard
# of dead brine shrimps in 35ppt
# of dead brine shrimps in 15ppt
Equipment List:
Lab Day/Section: Teusday/11
T.A: Victor
- Baking Soda
- 6 1L Bottles
- 1 Heating Lamp
- Tap Water
- NON-IODIZED SALT
- 1 Measuring Cup
- Brine Shrimp Eggs
- 3 Petri Dish
- 1 Airpump
- 3 Flexible Airline Tubing
- Magnifying Glass
Methodology:
To count the number of brine shrimps present in each petri dish... we used this grid method
Results:
Conclusion:
Best salt concentration:
10 Parts per thousand
