The English version follows below La Politique environnementale de l'Afrique de l'Ouest : mieux la connaitre pour faciliter son application L’UICN, dans le cadre de son programme « Partenariat pour la gouvernance environnementale en Afrique de l’Ouest (PAGE<http://www.iucn.org/page>) », en collaboration avec la Direction de l’Environnement de la CEDEAO et l'Union économique et monétaire ouest-africaine (UEMOA) a élaboré une note de synthèse de la Politique environnementale de l'Afrique de l'Ouest [Couverture Note politique environnementale AO] Cette note de synthèse vise à donner au public les repères essentiels pour une meilleure compréhension de la politique régionale environnementale de l’Afrique de l’Ouest. Rédigée dans un langage accessible et structuré de manière à en faciliter la compréhension, la note de synthèse se veut un outil pratique à la disposition du public pour l’aider à mieux s’impliquer dans les questions relatives à la gestion des ressources environnementales. [cid:image007.jpg@01D24B1B.76616420] La note de synthèse sur la Politique environnementale de l’Afrique de l’Ouest est accompagnée par une présentation animée. Elle vise à sensibiliser davantage les décideurs et les grands publics sur les enjeux de l’environnement dans la région et le besoin d’une implication de tous les acteurs pour la mise en œuvre de la politique.

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.

[Dialoguebarrages] Manuel sur le consentement préalable, libre et éclairé

by KOUNDOUNO Jérôme

10 octobre 2016, Rome - Le droit des populations autochtones de donner ou non leur consentement à des projets de développement ayant une incidence sur leurs ressources naturelles et leurs modes de vie a pris de l'importance grâce à un nouveau manuel destiné à guider les acteurs du développement dans la conception et la mise en œuvre de ce type de projets. Le manuel sur le Consentement préalable, libre et éclairé (FPIC)<http://www.fao.org/3/a-i6190e.pdf> présente les différents moyens de s'assurer que les populations autochtones puissent donner ou non leur consentement aux interventions proposées sur leurs terres et territoires, et ceci sans contrainte, avant qu'une décision ne soit prise, et avec les informations nécessaires présentées de manière culturellement appropriée.

In English below 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.

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 ><> ><> ><> <>< <>< <>< Dr. Nabil A.

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 .

Bonjour, La plupart des éleveurs je sais obtiennent plus de 60% taux de survie des alevins. Ma suggestion personnelle est d'arrêter l'alimentation de la saumure de crevettes vous donner les alevins.

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 ….

[Dialoguebarrages] Les impacts desastreux en Irak du barrage iranien Daryan

by Thierry Uso

Cela ne concerne pas l'Afrique de l'Ouest, mais c'est néanmoins fort intéressant ;-) The Save the Tigris and Iraqi Marshes Campaign have released a report on the impact of the Daryan Dam on the Kurdistan Region of Iraq. The Daryan Dam is a large dam currently under construction on the Sirwan River in Iran. The report highlights the controversial construction of dams for purposes of self-interest in a water scarce region despite evidence of their significant negative impact both locally, through displacement, and downstream, through reduced water flows. http://www.fame2012.org/en/2016/10/28/iranian-daryan-dams-desastrous-impact… --- L'absence de virus dans ce courrier électronique a été vérifiée par le logiciel antivirus Avast. https://www.avast.com/antivirus _______________________________________________ Dialoguebarrages mailing list Dialoguebarrages(a)lists.dialoguebarrages.net http://lists.dialoguebarrages.net/listinfo/dialoguebarrages
