How to measure a Daphnia

  , ,

📥  Zooplankton

One of my biggest problem in the past weeks was measuring the size of Daphnia we have in Vobster Quay. That's very important to understand how they can affect the mixing during the vertical migration and their life stage. Daphnia usually live for 2 months reaching the maximum body length. So different sizes means different ages.

Unfortunately the microscope I have in the Water Quality Lab @UniBath in Civil Engineering wasn't that powerful and even using my Snapzoom microscope adapter didn't help that much. The image was too blurry and I couldn't use even the ruler!
