Fisheries in CBNRM Training: Namibia Nature Foundation, Rundu 25-29 June 2018

Britta Hackenberg and John Hazam from Namibia Nature Foundation opening the Fisheries in CBNRM training workshop at Sarusungu Lodge, Rundu
A five day training workshop on fisheries protected areas (reserves) with a Community Based Natural Resource Management (CBNRM) approach was hosted by the Namibia Nature Foundation (NNF) with EU funding at Sarusungu Lodge in Rundu from 25 to 29 June 2018. 

The training was targeted towards Conservancies, Ministry of Fisheries and Marine Resources (MFMR) staff in the Directorate of Aquaculture and Inland Fisheries (DoAIF) and Ministry of Environment Tourism (MET) staff in the north east of Namibia. DoAIF staff from Katima Mulilo, Kamutjonga Inland Fisheries Institute (KIFI) and Rundu participated  as well as representatives from conservancies in Kavango West and East Regions and MET staff. The workshop was attended by 24 participants and facilitators

Ms. Britta Hackenberg from NNF opened the training workshop and highlighted the objective of exploring different alternatives towards the creation of community based fish protected areas/reserves within and outside conservancies. The five day workshop studied these alternatives in detail with professional guidance from Mr. John Hazan and Dr. Clinton Hay. Legal implications of Conservancies and Community Forest were scrutinized as well as other relevant legislation (Communal Land Reform Act, Traditional Authorities Act, Inland Fisheries Resource Act etc.). The role of Traditional Authorities (TA) and CBNRM were discussed. Dr. Clinton Hay presented the history of fisheries management and Fish protected Areas (FPA's) as well as the impact of the KAZA project and others like SAREP and OKACOM. He also presented guidelines on FPA establishment and fisheries in CBNRM.  Dr. Hay and Dr. Francois Jacobs (KIFI) also presented scientific evidence on the importance of FPA's with science based management recommendations. Dr. Hay also presented on how to develop a management plan for an FPA.

The workshop was very much participatory. Participants shared experiences with existing FPA's (Sikunga and Impalila), law enforcement and bilateral issues. The workshop drafted a way forward programme to guide legislative intervention and  progress with planned FPA's in the Kavango Regions and Zambezi Region.

KIFI Aquaculture: screening 3-Spot brood stock for conditioning

KIFI staff eagerly collecting 3-Spot tilapia for screening, separating male and female for conditioning
KIFI staff started the screening of 3-Spot tilapia (Oreochromis andersonii) in order to separate males from females. Over winter conditioning  of the males and females will take place in pond K1 (male) and K2  (female) from June to August. Final selection of brooders (200 male and 400 female) and replacement (60 male and 120 female) will take place during August 2018 for conditioning in order to start breeding from October 2018 to March 2019 according to the Aquaculture management plan of KIFI (last image). 

Job well done...!!!

Fish Harvest: Epalela Fish Farm: 24 August 2017



Epalela Fish farm hosted a fish harvest for the public on Thursday, 24 August 2017. The event was attended by droves of  community members and other distinguished guests who wanted to buy fresh fish. The event was organised by staff of the Directorate of Aquaculture and Inland Fisheries (DoAIF) from Onavivi and Ongwediva Inland Aquaculture Centers. More than 7 ton fish was harvested (7, 430 ton tilapia and 75kg catfish), processed and sold to the public.

Master of Ceremony, Dr. Moses Maurihungirire, Permanent secretary of the Ministry of Fisheries and Marine Resources

Proceedings were led by Dr. Moses Marihungirire, Permanent Secretary of the Ministry of Fisheries and Marine Resources as Director of Ceremonies. Honourable Dr. Chief Ankama delivered the main address. In his address Hon. Ankama passionately talked about the current state of aquaculture. He brought several of the local fish farmers to the front to showcase them as  an example of successful fish farmers and encouraged further steps to uplift the production potential of aquaculture by local farmers. He also encouraged integrated production with crops and livestock to further improve profitability of such ventures.

Hon. Chief Ankama, Deputy Minister of Fisheries and Marine Resources with some of  the fish farmers in the north
Mr. Renier Burger, Deputy Director of the Directorate of Aquaculture and Inland Fisheries during the Vote of Thanks explained that the  focus of our fish farms has moved from merely producing fish to becoming research demonstration facilities, whereby the focus is on research to improve the economic viability of aquaculture. In this case production is merely a function of research with the purpose to achieve the lowest possible production cost with highest possible yield. This research oriented approach resulted in Epalela fish farm achieving an internationally recognized Feed Conversion Ratio (FCR) of 1.57:1 (1.57 to 1) during 2013/14 from previous FCR’s of way over 2.5:1 (2.5:1). This means that only 1.57kg of fish feed is needed to produce 1kg of fish as opposed to more than 2.5kg of fish feed to produce the same amount of fish and represent a massive decrease in production cost. Fish feed constitutes about 70% of the production cost of fish with a gravity flow system as we have at Epalela. The current feed price (2017) from Zambia is N$9/kg FOB Livingstone. With transport the feed is landed at Onavivi at a total cost of N$10,46/kg (N$1,46/kg). Thus the production cost of the fish harvested during this event could be as low as N$23, 46/kg (FCR 1.57:1) He further stated that the depletion of the inland fishery resource (Zambezi, Kavango Rivers) resulted in a shortages of popular bream species at the open fish markets resulting in an increase in the price of these species to over N$50/kg. There is therefore huge scope for commercial investment in freshwater aquaculture as we are now in a situation whereby there will be sufficient return on investment for the industry to proliferate at a selling price of N$50 and above. There is also much potential for the development of a niche market for local tilapia, which is one of the tastiest fishes around.

Mr. Oliver Numbwa from Onavivi IAC then guided the proceedings of the harvest, processing and a lunch served with fresh fish amongs others

Report by: De Wet Siluka and RD Burger
Hon. Bernhard Esau (MP), Minister of Fisheries and Marine Resources (MFMR) visited Fonteintjie Fish Farm in Keetmanshoop on Thursday, 17 August 2017. He was accompanied by the Hon. Lucia Basson (Governor of Kharas Region), Hon. Hilma Nicanor (Deputy Minister of veterans' Affairs and the Champion of the establishment of Fonteintjie Fish Farm), and a delegation from //Karas Regional Council. MFMR staff that accompanied Hon. Esau was Mr. Renier Burger (Deputy Director: Aquaculture and Inland Fisheries), Ms Unda Tjihuiko and Ms. Kalenasho from Hardap Inland Aquaculture Centre along with Mr Simasiku (MFMR Keetmanshoop Office). Mr. Simasiku guided the delegation through the old section of the farm and then through the uncompleted facility still under construction.

Hon. Esau expressed his deepest concern with the continuous delay in the completion of this aquaculture facility supposed to have already being producing fish for the community. The Ministry of Fisheries and Marine Resources already paid for the facility in full and are now delayed by other role players.

The orchard and old ponds at the facility is taken good care of by the Directorate of Aquaculture and Inland Fisheries staff based in Keetmanshoop under the leadership of Mr. Simasiku.
