Product Description

We have the latest magnet for separating polarised egg cases directly in the hatcher vessel close to the point of harvesting Artemia nauplii. It has a single magnetic rod which is designed to be easy to clean and includes a grippy handle. Suitable for use with our 17 L hatcher.

Harvesting Methods

Method 1: Direct harvest: suitable for small hatching volumes

Small tanks can be harvested without any specific preparation. Simply separate the cysts from the nauplii by inserting the SEP-Art EasyMag tool into the hatching tank. Repeat the handling until all the cysts are collected and a pure nauplii suspension is obtained.

Method 2: After concentration. Suitable for small to relatively large hatching volumes.

  1. Discontinue the aeration upon completion of the hatching. Preferably cover the tank.
  2. Allow the empty shells to rise in the hatching suspension for about 5 mins. Simultaneously, the nauplii and the full unhatched cysts will accumulate near the tank’s outlet.
  3. Harvest the hatching tank (excluding empty shells floating at the surface) in a net or other collecting device.
  4. Transfer the collected nauplii and unhatched cysts to a concentrator – tank and add clean sweater to about 10% of the initial hatching volume, applying strong aeration.
  5. Submerge the SEP-Art EasyMag for about 1 min in the concentrated suspension (until fully loaded with cyst shells and empty cysts).
  6. Withdraw the loaded Sep-Art EasyMag from the Artemia suspension and remove the attached cysts and shells from the surface of the magnets with a gentle water flow (collect in a separate net for later disposal0.
  7. Apply steps 5,6, and 7 until the Artemia nauplii suspension is fee from cysts and a pure Artemia nauplii suspension is obtained.
