THE GLOBAL AGENDA FOR SUSTAINABLE LIVESTOCK: 8-12 MAY 2017, ADDIS ABABA, ETHIOPIA







The Deputy Minister, Hon. Dr. Samuel Chief Ankama was officially delegated to attend the 7th Multi Stakeholder Partnership Meeting in Addis Ababa. He was accompanied by Mr. Renier D. Burger, Deputy Director for aquaculture in the Directorate of Aquaculture and Inland Fisheries. The main purpose of this official mission was to network with the international livestock sector towards promoting freshwater aquaculture as an integrated component of livestock (and crop/horticulture) farming in order to improve the viability and profitability of such integrated farming system.
Honourable Ankama and Mr. Burger represented Namibia in several group meetings. Hon. Dr. Ankama was also selected for the main panel discussion were he highlighted the importance of livestock farming (including aquaculture) in communal and commercial areas in Namibia with special reference to women headed households and women as owners of livestock/fish ponds.

THE GLOBAL AGENDA FOR SUSTAINABLE LIVESTOCK
 The Global Agenda for Sustainable Livestock farming/herding provides a platform, regionally and locally rooted, to comprehensively address the sector’s multiple challenges towards sustainable development. Its main orientation is based on the UN Agenda 2030 for Sustainable Development and aligns all its activities to advance the contribution of livestock to achieving the Sustainable Development Goals (SDGs).

 The 7th Multi Stakeholder Partnership Meeting focused on the multiple benefits that livestock-based solutions can provide for a broad range of stakeholders. This focus is a logical follow up of the 6th meeting held during 2016 in Panama where the links between sustainable livestock sector development and achieving of the SDGs were demonstrated.
 The meeting was guided by a multi-faceted 5 day program where, among others, tools to facilitate sustainable livestock sector development were  discussed, cases of practice change were demonstrated and learning tours to show local efforts towards sustainable sector development took place.
Venue of the Livestock Forum: Hilton Hotel in Addis Ababa
 The meeting was held at the Hilton Hotel in Addis Ababa from 8-12 May 2017and brought together more than 250 livestock specialists from over 50 countries to demonstrate the positive contribution of livestock to the lives and wellbeing of hundreds of millions of people on the planet, and foster the sustainable development of this rapidly-growing sector. Key actors in the livestock sector worldwide, donors, government and public sector representatives, UN agencies, multilateral and non-government organizations, civil society, academia and the private sector came together to discuss and propose how to best foster the sustainable development of this rapidly growing sector. Driven by population and economic growth, particularly in lowmiddle income economies, the demand for livestock products is expected to increase by about 70% in the coming 30 years. Whilst the livestock sector contributes to society in so many ways, including to food and nutrition security, it can also pose challenges to the environment and human health. This astronomical demand presents opportunities for the livestock sector to contribute to global development challenges by promoting sustained economic growth, inclusive social and human development, and the efficient use of natural resources.
 IMPORTANT TAKE-AWAY FOR NAMBIA FROM THIS FORUM

Namibia as a member of the UN are implementing provisions of the UN Agenda 2030 for Sustainable Development and protection of the environment as captured in Namibia’s Constitution, Vision 2030, the SWAPO Party Manifesto, Harambee Prosperity Plan, the consecutive five year National Development Plans implemented by relevant line ministries by means of five year Strategic Plans. Namibia also partake in several multilateral and bi-lateral agreements/cooperation in the sub-region and internationally with regard to the livestock sector.
Namibia is the world leader with regard to community management of livestock and natural resources by means of conservancies under the Community Based Natural Resource Management (CBNRM) approach. Conservation farming in communal areas should focus more on integrated farming practises by integrating crops, livestock and aquaculture to improve viability and profitability/income of households/farmers.

Note from editor: The use of Methyl Testosterone  for sex reversal of fish not yet allowed in Namibia

Tilapia production in ponds for smallholder farmers.

Fish farming results can be improved by using only male fish, especially in ponds. This is because males grow faster than females, and if there are no females they do not waste energy breeding. In mixed sex fish ponds, the other problem is unwanted breeding, and the many small fish that are then eating the food that the big fish should be eating, and this stops them
growing.
Advantages of this seed system are also less handling and transport of fish seeds, so there is less mortality and it is much cheaper than buying fingerlings from other suppliers. When harvesting, the fish are much bigger and more even in size.

How to produce your own monosex male fish.

Even if you only have one fishpond, you can produce your own male fish seeds. This can be
done using a net-cage called a HAPA. If you have many ponds, you can use one just for monosex fish and fingerling production, and even sell these to other fish farmers. Notice these HAPAs are covered with thin nets on top also to stop birds from eating your small fish and to stop the big fish from jumping out. HAPAs look like this (below).



Once you have this in place, you will need to stock it with breeding fish. In HAPAs, the number of fish to stock depends on the size of the HAPA, so for every square meter of surface area you will need three females and one male fish. Breeding fish can be from your own ponds if you have mixed-sex fish, or bought from other fish farmers, or from the Department of Fisheries. Choose good healthy fish, and if you have kept the males and females separate (you can use HAPAs for this too!) for some weeks they will be fat and will breed quickly. Do not use fish thatwere treated with MT as breeders, and yowill need to make sure you have the correct numbers of males and females, so check the sex of the fish. You can do this by looking at the sex openings which look like this. After putting the breeders together into thHAPA, after some weeks you will seethe small fish swimming around in the HAPA. Now yoneed to gently lift the net up and take out the breeding fish, leaving the small fish in the HAPA. Check the mouths of the breeders, if some of them still have eggs in the mouth, drop them back and release the net, then wait a few days and check them again.



Feeding the MT starter feed

To make all the fish male, you will need to feed the small fish, called fry, a feed that contains a chemical called Methyl Testosterone. Some farmers add this to their feed themselves, but you can also buy fish feed that already has this chemical in Zambia. This feed is called MT starter.
Once you have removed the breeders, start feeding the fry the MT starter twice or three times a day. Make sure you do not overfeed! So look and see how much they are eating and there should be no feed remaining after about an hour. You will need to feed them this feed for at least 30 days. At the end of this they should be nearly all males.
After this the small fry can be moved to open ponds, and if the HAPA is already in the pond to be stocked, it can be done simply by pushing the sides of the HAPA down into the water. If they are to be moved to another pond, take care not to hurt the fish when moving them, and not to cause them stress by being too hot or cold, or too many in a container.

If you have another small pond, you can also use that for growing these fish to the next stage, called fingerlings. This normally is for another two months. After that the fish are much stronger and can be transferred to the growout pond for the final stage without being hurt.

When harvesting a growout pond, the best practice is called a TOTAL harvest where you take all
the fish out and sell them. Draining the whole pond is the best way to do this. Then the pond can be dried, repaired and prepared by applying agricultural lime and refilled with water ready for the next crop of fish. Drying out the pond and using lime will kill any remaining fish and sterilize the pond so that you do not have unwanted fish left over or wild fish breeding in the growout pond the next time it is used. This is important otherwise the advantages of having male fish only will be lost. It also helps to prevent diseases, and allows the air and sunlight to release more nutrients that will help to grow more natural food for the fish.
MT starter feed is available from Novatek, and advice on fish farming is available to members of the Aquaculture Development Association of Zambia. Contact details are below.
