Science Buddies: "Ask an Expert"

Hey Science Buddies,

My name is Ashley and I'm in 9th grade living in Corona, CA. This year my experiment is on utilizing daphnia magna to test the water toxicity from watersheds. My questions are: Do you have any suggestions on where i can buy culture starters of daphnia magna? Do you have any suggestions on what's the best way to culture them?

Please e-mail me back as soon as possible. Thank you very much!!
Sincerely,
Ashley

Hi Ashley,

A place to buy daphnia magna is at:

Note, the above is a "Sponsored Link." In other words, it is a paid advertisement. Normally, I don't select links of this kind, since most times, one is just looking for information. In this case, however, you were looking to buy a product.

The folks at Ward's Natural Science may be able to help you on your culture question as well as to which daphnia magna product meets your needs.

Hi Ashley,

Carolina Biologicals is a good place to start, I searched for "Daphnia" and got these results:

You can get just the cultures and food separately, or a kit with everything they think you need, including care instructions.

I did a Google search for "culture Daphnia" and got a few informative-looking hits.

I like this project idea, you are testing water quality by going directly an essential question: can it support living creatures?

Good luck
