Artemia

As spring proceeds, it is not always easy to collect pond food with the right size and in the right abundance for all fry. For example, when fishing for food I now need to skim the water surface carefully to get the smallest zooplankton. Contrary to my original plans, I thus decided to raise some Artemia. It is used as a supplement, or as the basic food to raise alevins to a size where I do have zooplankton available in.

To reduce noise and save some energy, I don’t use an aerated and heated bottle anymore. Siberian Artemia ggs harvested from Kulundinskoe Lake are hatched in small containers, in volumes of 500 ml to which I add 10 grams of seasalt. The Artemia hatches gradually at room temperature. When abundant, I separate the husks from the nauplii in a bottle with a valve. The nauplii are tapped and rinsed with tap water (which doesn’t contain chlorine).
This type of Artemia nauplii survives well in the fish tanks, often until the next morning.

  1. I’ve reduced the water depth to 1 centimeter and things seems to work even better.
