Stellenbosch University seeks to spread best aquaculture practices across Africa

1 August 2019, at 7:30am

“Aquaculture is crucial to addressing major economic problems in Africa today,” according to Henk Stander, researcher at the Aquaculture Division of the Department of Sciences at the University of Stellenbosch. “Whilst fish catches have declined considerably, there’s a pressing need for more marine protein to cope with high population growth.”

Stander was speaking at the recent workshop on Critical Insights in Fish Farming, jointly run by Ghana’s Ainoo-Ansah Aquaculture Centre, the University of Cape Coast and South Africa's Stellenbosch University. The programme was attended by senior managers in the aquaculture industry and investors in the process of starting fish farms.

Jacob Ainoo-Ansah, CEO of the centre and coordinator of the programme, said that the programme brought aquaculture practitioners up to date with current trends.

“For example, we dealt with issues relating to aquaponics at some depth, because it is becoming important to optimise the use of water, and the appropriate systems must be integrated in our fish farms. In the light of new challenges being encountered with diseases, we also took a good look at health and disease management. And since most fish farmers today are eyeing the export market, we surveyed the international market. Fortunately, we had two competent resources persons to guide us. We expect to increase this collaboration in the coming months.”

Stander noted that most African countries were implementing aquaculture strategies and that the sector could play a useful role all over Africa, even in the countries that are producing high volumes of fish. He cited two interesting examples.

“In Malawi the inland water bodies have been overfished, and per capita fish consumption has dropped from 14 kg in 1970 to the current 5.4 kg. The need to increase production is urgent, and aquaculture possesses the capacity to help increase fish supply. What is needed now is investment feed and technology, and in training.

“Namibia is a major fish exporter, but the bulk of her output comprises high value fish. Her per capita fish consumption is 11 kg, and the Minister of Fisheries and Marine Resources recently expressed his dissatisfaction with this figure, and committed himself to raise it to the world average of 21.4 kg per year”.

Stander also added that effective training, especially related to the use of new technology, is crucial for successful aquaculture production.

“New technology is available today which makes it possible to achieve high returns on investment and to achieve badly needed fish output. It is our hope at Stellenbosch to contribute to the transfer of skills through this programme.”

Mark Joscelyne, also of Stellenbosch University, said their extensive experience in aquaculture research and extension service to farmers will be useful to African fish farmers at this crucial stage in the development of the industry.

“This workshop provided us with a good appreciation of the needs of the African industry. We have considerable experience in both research and in assisting fish farmers. This training programme offers a platform for close collaboration with colleagues around Africa.”

Isaac Bello, a Nigerian bank director, is taking early retirement to start a fish farm in Lagos State. “I have already secured a sizeable plot of land and mobilised some capital. I have been planning to enter aquaculture for some time now. I am glad I attended this programme because it has offered me the depth of information I needed. I have also made some useful contacts which will be beneficial in the near future. Now I know exactly what to do when I return to Nigeria”.

After more than two decades in the mining industry, Atta Mensah, a civil engineer, has secured an extensive tract of land in Okorase in the Ashanti Region, having tested the soil and found it suitable for fish farming.

“There is a generous supply of good quality water. I will adopt the strategy to suit a combination of fish and vegetable and crop production,” he said.

Ainoo-Ansah is excited about the response to the online course which the centre is running jointly with Stellenbosch University.

“It’s reaching our target group – people working in aquaculture who may not have the opportunity to attend formal courses. The course has been designed to suit the needs of African fish farmers today, and we hope to be able to reach many people all over Africa in the shortest possible time,” he said.

Professor Anthony Afful Broni, vice-chancellor of Ghana’s University of Education, has high hopes for the online course.

UMass Sustainable Aquaculture Online Courses

Aquaculture is an increasingly important source of safe, nutritious, and sustainable seafood for people worldwide. Globally, aquaculture production must double by 2030 to keep pace with demand. These increases in demand for aquaculture products, food security considerations, and job creation have generated an increased need for skilled workers.

Discover how you can be part of this rapidly expanding industry.

“Distance learning is a very useful method of training African farmers. Most of them do not have the capacity to attend formal courses. And as the head of a university for which distance education is a key activity, I find this online aquaculture course very innovative. The content material available to the student is considerable, and is presented in a manner that makes learning very practical.”
