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

Hatching:

>

# of brine shrimps in 35ppt

<

# of brine shrimps in 10ppt

# of brine shrimps in 15ppt

Survival:

shortest

# 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

longest

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:

Predictions

Best salt concentration:

10 Parts per thousand
