Bonjour
Utilisez Gemna 0.1 mm de Skretting ou Essence 0.2 mm- 0.3 mm de COPPENS.
J'obtiens de très bons résultats et je produit 150 000 à 200 000 alevins toutes les 2 semaines avec deux femelles.
Artemia causer une mortalité élevée que vous avez dit quelque chose de mal sur la formule. Je l'ai laissé depuis 2 ans pour cette 2 fois de nourriture sèche mentionnée.

Hello
Use Gemna 0.1 mm of Skretting or Essence 0.2 mm- 0.3 mm from COPPENS.
I get very good results and produce 150 000-200 000 fries every 2 weeks with two females.
Artemia cause high mortality as you told something wrong on the formula. I left it since 2 years for this 2 time of dry feed mentioned.
Thanks

Hello Neil,
Sorry for the lateness of my reply.
Kindly Google 'inve artemia' u ll be shown the product and the producer. For years hatcheries around depend on this product for the fries feed. I guess they changed something in the formula which is now making the fries to die once they start feeling on it.
I wouldn't mind if i can have access to what u use over there and be able to produce my own artemia. The best we do now is get 0.5-0.8mm of feeds meant for fingerlings. Grind to powder and feed the fries.
Tunde
