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.

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.

The type we use here required you apply the quantity the fries can eat into
the water and the fries will feed on it. (inve type)

Bonjour à tous,
Nous avons eu le même problème des faibles taux de survie des juvéniles de
poisson-chat africain Djo provient principalement de cannibalisme, mais a
réussi à surmonter ce problème par quatre procédures:
1. Le classement des alevins chaque 8-10 jours (pas moins et pas plus).
2. Dépôt direct alimentaires (rotifères) pour la nouvelle alevins hachurée.
3. Construire petite brique plus approprié pour le poisson-chat de
fingerlings de réservoirs d'élevage les hapas de charbon net.
(Et la quatrième procédure était de réduire l'agressivité des géniteurs, si
vous n'appréhendé à partir de ce problème, vous pouvez l'éliminer)
Les mâles et les femelles 4. Injecter avec ovaprim ® réduit l'agressivité
et nombre accru mà d'œufs.

Dear All,
We had the same problem of low survival rates of juveniles of African
catfish which mainly came from cannibalism, but we managed to overcome this
problem through the following four procedures:
1. Grading the fry each 8 – 10 days (not less and not more).
2. Introduced live food (rotifers) for the new hatched fry.
3. Built small brick tanks which is more suitable for rearing the
catfish fingerlings than net hapas.
(And the fourth procedure was to reduce the aggressiveness of the
broodstock, if you don’t suffering from this problem you can eliminate it)
4. Inject both males and females with ovaprim ® which reduced the
aggressiveness and increased egg numbers.
Hope to find it useful.
Best regards,
Nabil

Good morning Koba
With clients and on our own R&D facility we have put enormous effort into
perfecting the survival and growth rate of African catfish over the past
years. I can tell you that there are several factors that are key to
obtaining this, including optimising both water quality & feed, but even so
a 50% survival is not realistic. If you get a 20% survival from egg to 1kg
you are doing well.
Regards,
Leslie
Bonjour Koba

qu'il ya plusieurs facteurs qui sont essentiels à l'obtention de ce, y
compris l'optimisation de la qualité de l'eau et de l'alimentation, mais
même si une survie de 50% n'est pas réaliste. Si vous obtenez une survie de

Bonjour à tous
Juste savoir si quelqu'un peut me donner des infos sur comment faire pour
avoir un taux de survie d'au moins 50% des alevins de clarias gariepinus.
En effet, le taux d'éclosion est bon mais déja à partir du 3ème jour de
nourrissage à l'artémia décapsulé on observe une forte mortalité et pour
les jours suivants. Et pourtant on fait un bon siphonnage, l'eau (eau de
forage à ph =5.3) sur les larves est renouvelée au moins 2 fois dans la
journée après s'être oxigénée.
J'ai à un moment donné pensé que la cause de la mortalité des alevins
pouvait être soit des virus, bactéries, levures ou champignons. Alors j'ai
fait installer un stérilisateur UV de 30 watt à travers lequel l'eau
transite avant d'atteindre les larves mais pas d'amélioration.
Si quelqu'un a donc une expérience en la matière je serai très sensible à
sa bonne volonté de partage.
Merci

Hello everyone
Just to know if anyone can give me information on how to get a survival
rate of at least 50% catfish fingerlings gariepinus.
Indeed, the hatching rate is good but already from the 3rd day of feeding
decapsulated Artemia there are high mortalities and for the following
days. And yet we also siphoned off water and replaced it (well water at
pH = 5.3) for the larvae repeating this at least 2 times a day after the
water had been well oxygenated.
At first I thought that the cause of the mortality of the fry could be
either virus, bacteria, yeast or fungi. So I installed a 30 watt UV
sterilizer through which the water passes before reaching the larvae but no
improvement.
So if anyone has experience in this area I will be very willing to hear
from you .
Thank you

*Email and mobile phone whats app networks developing commercial
aquaculture in Nigeria *
Dear all
Please see below note how this simple yahoo email catfish farmers forum
in Nigeria now with hundreds of members all over the country are buying
and selling not just fingerlings and market fish but also inputs
feed fertilisers etc also for questions and advice There is also a
similar equally popular Nigerian catfish farmers mobile phone whats app
group which has daily messages on the same subjects and thus huge
networks of fish farmers communicating with each other on daily basis-
In the last weeks on the catfish farmers app they have been
discussing market process for their grow out fish and how they can
potentially state and then country wide try to control prices - as
their margins are ever declining due to the continually increasing prices
per tonne of commercial feed in the country………………….
Please note this for sarnissa fish farmers in other countries -
also for those involved in aquaculture development across SS Africa
both govts and also national and international donors and investors -
These email and mobile phone whats app networks cost next to nothing to
set up and normally just the time of a dedicated individual to run them
- And the impacts and concrete positive outcomes from them are huge ….
Best wishes Will
