La meilleure façon d'éliminer les solides consiste à utiliser des réservoirs ronds à drain central. Je suppose que vous avez des canalisations rectangulaires, vous avez donc besoin d'un bassin de décantation à l'intérieur du réservoir (difficile à réparer les réservoirs existants) ou juste à côté, où l'eau peut rester immobile pour que les solides se déposent. Ensuite, vous pouvez pomper l'eau dans les réservoirs de production. Je ne voudrais pas acheter la souche Akosombo tilapia. Ils sont soupçonnés d'être porteurs de maladies et ne poussent pas très bien. Je pense que la meilleure approche pour le Togo serait d'importer le tilapia GIFT d'une source fiable. Randy The best way to remove solids is to use center-drain round tanks. I assume you have rectangular raceways, so you need a settling basin either inside the tank (hard to fix existing tanks) or just next to it, where the water can become still so the solids will settle. Then you can pump the water back into the production tanks. I wouldn't buy Akosombo strain tilapia. They are suspected to harbor diseases and do not grow very well. I think the best approach for Togo would be to import GIFT tilapia from a reputable source.

Azolla Pisciculture Aquaculture Togolaise Request SARNISSA email forum francaise Hello everyone. I am a Togolese fish farmer. I raise make tilapia by raising fish in tanks. I would like to know if one or more people have experimented with azolla by putting it directly in the tanks and if this has helped to improve the quality of the water. The second thing I would like is if there is a technique or fixtures that allow to recover in a subsidiary structure the waste (food remaining, the fish faeces) from the tanks (without necessarily draining the water in the bottom of the tank ). My last request is to look at the improved strain called Akossombo from Ghana ? . I would like to know where I could find some. Thank you for your contributions. Viwanou EDORH Tel: 0022897881818 Bonjour à tous. Je suis un pisciculteur togolais. Je fais du tilapia en elevant les poissons dans des bacs. Je voudrais savoir si une ou des personnes ont fait des expériences avec l'azolla en la mettant directement sur les bacs et si cela a a contribué à améliorer la qualité de l'eau. La deuxième chose que je voudrais est s'il existe une technique ou des montages qui permettent de recuperer dans une structure annexe les déchets (nourritures restantes, les cacas des poissons) provenant des bacs (sans obligatoirement vider le bac). Ma dernière demande regarde la souche ameliorée dite Akossombo. Je voudrais savoir où je pourrais en trouver. Merci pour vos contributions.
