[Forum dialogue on dams] Documentation Sourou Mali

by CESSOUMA Bamadou

Bonjour, J'ai l'honneur de partager avec vous cet important document de planification sur le bassin du Sourou élaboré par la Global Water Initiative Mali. Il s'agit entre autre du Schéma Directeur d'Aménagement et de Gestion des ressources en Eau du Sourou (portion nationale du Mali) validé le 04 février 2012 en atelier National à Bamako. Merci et Bonne exploitation.

Grâce à ces années d'expérience et des nombreuses leçons apprises, le vieil adage est vrai: «faire simple », en particulier pendant l'apprentissage du travail. Je suis allé en Namibie avec la FAO pour la pisciculture et je sais que vous avez potentiel. Mais pour les nouveaux venus dans ce travail, il est préférable de commencer petit avec systèmes de faible intensité et faible investissement, tels que l'élevage de poissons dans les étangs, les cages ou des réservoirs, comme cela se fait au Nigeria. Il est toujours préférable d'investir dans un voyage pour visiter les fermes qui ont réussi et apprendre des erreurs des autres. i Les systèmes intensifs en eaux recyclés nécessitent une gestion qualifiée 24 heures par jour, et ce n'est pas pour les nouveaux arrivants dans le secteur. Quelques-uns des meilleurs pisciculteurs du Nigeria ont voyagé en Europe pour visiter des fermes de poissons aux Pays-Bas et les Royaume-Uni. Maintenant, il y a un certain nombre de fermes piscicoles qui ont réussi à visiter en Afrique, au Nigeria, au Ghana, en Ouganda, au Kenya, en Zambie, etc Vous pourriez envisager de visiter certains de ces pisciculteurs et réorienter vos efforts sur la base des leçons apprises > Everyone, > > A number of criteria and conditions are required for developing fish > farming and many have been tried in Africa.

suite des échanges sur les les système "RAS" Le 04/10/2012 03:32, Warren A.

Le Vietnam a récemment produit 1 million de tonnes par an de poisson-chat Pangasius, rien à partir de systèmes RAS, pourquoi? Systèmes RAS sont utiles pour: 1) Produire des espèces de grande valeur dont une bonne maîtrise de l'environnement est nécessaire. 2) Produire du poisson où la biosécurité élevé est nécessaire - SPF crevettes, le barramundi en nurserie, etc 3) Production de poissons tropicaux dans les climats où la température de chauffage est un coût important et vice-versa sans doute, par exemple si vous voulez produire du saumon en Thaïlande au moyen de refroidisseurs. 4) Production de poissons où le foncier est très coûteux - comme dans une ville. 5) Produire du poisson dans les zones arides et où le sol n'est pas adapté pour les bassins, comme dans le désert. 6) Pour les aquariums publics. > > Hi Badiane, > > If RAS systems are so profitable, how come Asia doesn’t produce > tilapia this way?

voir ci-dessous, les "mauvaises" traductions des échanges de la liste en langue anglaise concernant les systèmes de pisciculture en eaux recyclés Le projet Hydrofish ayant été créé en 2011 selon le lien http://www.hydronov.com/2010/Images/Projets/01-Diaporama/DP-IvoryCoast.htm, est-il possible d'avoir quelques information complémentaires et notamment: Avez vous déjà produit 3000 tonnes /an ou est ce une production attendue ? Le coût de production du Clarias est-il le même que celui du tilapia ? Quelles sont les quantités annuelles respectives produites ? ... En vous souhaitant un plein succès, cordialement Olivier M. Le 03/10/2012 14:14, Leslie a écrit : Je ne crois pas qu'il existe une solution unique à l'aquaculture à travers le continent. Il faut d'abord considérer la combinaison d'espèces et le climat, et puis la nature du site, la disponibilité électrique, la qualité des aliments, les connaissances et l'expérience du personnel, le marché existant et de nombreux autres facteurs. Il y a certainement une place pour les bassins de la terre et pour les cages. > I do not believe that there is a single solution to aquaculture across > the continent.

Efectivement, ce n'est pas de petits investisseurs qui seront en mesure de le mettre en place, mais seuls des investisseurs de premier plan peuvent se permettre d'en disposer. En ce qui concerne le coût de production par kg pour mon cas, le "RAS" que je dirige en Côte d'Ivoire, il est d'environ 1000 f cfa (mais le prix de vente est excellent), il peut être plus élevés que celui des cages oudes étangs de production. Mais combien de production, vous pouvez le faire dans l'année avec la RAS tandis que pour les cages ou les étangs que vous ne pouvez pas faire plus de 2 récoltes. Nos RAS ont seulement 0,4 ha de superficie et nous produisons 3.000 tonnes à l'année. 0,4 ha de l'étang ne peuvent pas le faire. L'impact sur l'environnement de la RAS est inférieure à celui des cages ou des étangs. Le peu d'eau qui rejetée est traitée et réutilisée Le problème de la RAS en Afrique, c'est qu'ils n'ont jamais été géré par des gens compétents. Faire la pisciculture n'a jamais signifié que pour pouvoir gérer un "RAS",il ne fallait pas de la haute technologie (?) Votre poste (position ?) ne prend pas en compte de nombreux facteurs. Pensez que le RAS ne fonctionnera pas en Afrique, c'est vraiment arrêter le développement de ce secteur. > > RAS is now essential for the development of aquaculture in Africa. ok > the cost is high (energy, tech, food, etc...) but it is very > profitable.

Bien qu'il n'y ait pas de doute que RAS a sa place dans le schéma général des choses, la plupart des applications de ces technologies sont généralement seulement rentables pour des tâches telles que des écloseries et holding systèmes.En Afrique, avec une telle richesse de sites encore inexploités pour les étangs alimentés par gravité et des plans d'eau de qualité pour les cages, il faudra longtemps avant que RAS puissent produire des poissons au même prix. > Dear All, > > Well said Nick! > > Many of the people selling such systems are technical sales people > with little or no background in Aquaculture in Africa, and some simple > calculations would show their systems are not competitive with > traditional pond-based or cage-based production techniques.

Mariculture commerciale, une autre opportunité pour l'Afrique

by sidiki keita

Chers membres du forum Après 3 jours de Symposium sur la mariculture à Dakar, je suis une fois encore convaincu de l'importance et de la possibilité de développer les potentialités aquacoles en Afrique Sub saharienne. A travers la COMHAFAT en collaboration avec SARNISSA, le CIRAD/IFREMER, les participants ont bénéficié des expériences réussies en Namibie, Afrique du Sud ....avec peu de moyens et un système de production simple et reproductible. Comme il se trouve que les potentiels de mariculture sont riches et diverses en Afrique, une telle rencontre de partage d'expériences reste un des meilleurs créneaux de transfert de compétence. La production des fruits de mer ( abalones, huitres, crevettes....) à travers la mariculture reste une source de revenue très intéressante pour nos populations mais aussi de lutte contre l'insécurité alimentaire. Alors faut il la saisir? Amicalement Sidiki KEITA, Directeur régional de la pêche et de l'aquaculture, Guinée Forestière, N'Zérékoré République de Guinée Tel: (00224) 63460143 / 64460143 / 67717020 E mail: sidikikeita(a)yahoo.fr

Re: [Sarnissa] Sympossium on potential for mariculture development in sub-saharan Africa: Dakar Senegal-26 to 28th Dec.

by Olivier MIKOLASEK

Le symposium vient de conclure sur le potentiel de commercialisation de la mariculture en Afrique sub-saharienne à Dakar-Sénégal était unique en son genre auquel j'ai jamais assisté. Cet événement a rassemblé un large consortium de praticiens de la mariculture : investisseurs privés, chercheurs, producteurs, établissements de formation, ONG et dirigeants du Gouvernement et commerçants pour partager leur vision du développement de la mariculture. J'ai réalisé qu'il se passe beaucoup de chose en Afrique dans le développement de la mariculture dont nous devons tirer des leçons. Par conséquent, les potentiels de la mariculture sont riches et diversifiées en Afrique. Cependant, plus de planification réaliste est nécessaire pour réaliser ce potentiel en mariculture comme cela a été résumé dans le dernier jour de la présentation. Aussi pour permettre aux autres personnes d'apprendre de nous, nous avons besoin de documenter nos activités de terrain. Je pense que Will et Beatrice partageront le rapport final de la symposium avec la communauté SARNISSA.
