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.

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 .

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 ….
