NutriFish Project Registers Significant Achievements
The project has made great strides in reducing malnutrition amongst vulnerable communities in Uganda by improving the acceptability and consumption of small pelagic fishes (SPFs). SPFs are rich in bioavailable micronutrients including iron, zinc, calcium, vitamin A and essential fatty acids (Omega 3, 6).
Overview
Malnutrition remains a serious challenge to human health and economic development in Uganda. Due to limited access to micronutrient-rich foods and animal protein, especially fish, 32% of women between 15-49 years are anemic whereas 30% are zinc deficient. 53% of children below five years of age are anemic and 70 % zinc deficient.
The nutritive value of the Small Pelagic Fishes (SPFs) cannot be underlooked in efforts to address the challenge. The SPFs are rich in bioavailable micronutrients including iron, zinc, calcium, vitamin A and essential fatty acids (Omega 3, 6). Besides, they are consumed whole, which enhances their nutritional benefits compared to the large fishes. Most consumers, including vulnerable groups in rural and peri-urban communities can purchase SPFs in small quantities at relatively affordable prices. The SPFs are therefore crucial in improving human nutrition, particularly during the first 1000 days of life (from conception to the second birth day) as they contribute to maternal health and better child development. SPFs are however not being consumed in sufficient quantities due to high levels of adulteration with grit, soil and sand; off-flavors (smelly fish); bitter taste and lack knowledge of the different methods of preparation. Traditionally, the SPFs are regarded as fish for the poor and livestock. Currently per capita fish consumption in Uganda is between 10-12 Kilograms per person per year which is below the internationally recommended amount of 26 kilograms per person per year according to the Food and Agriculture Organization (FAO).
The NutriFish Project and achievements registered
Through a project titled NutriFish, researchers from Makerere University together with their partners from the National Fisheries Resources Research Institute (NaFIRRI) – National Agricultural Research Organization (NARO), NUTREAL Limited and McGill University, Canada in 2019 set out to increase the availability, accessibility and consumption of SPFs for sustainable food and nutrition security and better livelihoods of vulnerable groups in Uganda. Led by Dr Jackson Efitre from the Department of Zoology, Entomology and Fisheries Sciences, Makerere University, and supported by the International Research Development Centre (IDRC) and the Australian Centre for International Agricultural Research (ACIAR) through their joint programme, Cultivate Africa’s Future Fund (CultiAF), the researchers developed five high-value nutritious products (baby food, sauce, maize meal, snacks, and seasoning) using Mukene. A 50g portion of the baby food flour provides more than one-third of a child’s daily protein, iron, zinc, and folic acid requirements. The researchers also developed a Mukene recipe book, containing 16 recipes rich in protein, calcium, zinc, and iron. The cookbook was endorsed by the Minister of State for Fisheries, Hon. Hellen Adoa. Through the NutriFish Project, fishers have been helped to access loans to purchase boats and fish containers which improve hygiene and quality by improving drainage and reducing compaction of fish. Two enterprise fishing groups with over 70 boats have been established and are working together – an approach which ensures more consistent supply and standards, and results in over 3.7 tons of fish caught each month. The research team also developed an application (eCAS system) for tracking fish catches. By September 2022, 8,960 records of catch data had been collected and transmitted through the eCAS system by trained local enumerators. Over 200 stakeholders are using the application, including the Directorate of Fisheries Resources and the Fisheries Protection Unit, which uses the data to help prevent overfishing.
Other achievements registered under the project include the development of solar tent driers – greenhouse-like structures that reduce the risk of contamination – provide clean and efficient storage and drying, especially during the wet season subsequently reducing post-harvest losses. The increased fish quality has doubled fishers’ incomes, from US$1 to US$2/kg, and tripled the shelf-life of dried small fish to almost five months. The driers have also attracted the attention of policymakers, with the Sectoral Committee of Parliament on Agriculture, Animal Industry, and Fisheries specifically recommending their use in April 2022 for improving fish processing. To encourage consumption of Mukene products, NutriFish developed a radio-based awareness campaign. More than 12 million listeners were reached by 29 different ‘spot’ messages in local languages and four 15-minute in-studio conversations – a significant step in tackling long-standing social beliefs that Mukene is food only eaten by poor families or animals. The project conducted awareness training with 326 people (200 women) to reduce gender inequalities. As a result, domestic violence dropped by 30%, the number of women in the fish value chain increased, more couples began to make joint household decisions, and more men carried out household tasks, increasing from 15% to 20%. The project also trained eight Graduate students, who have gained valuable skills and knowledge thus boosting critical human resource needs in the fisheries sector.
NutriFish Product Launch and Dissemination Event
On 27th February 2023, the College of Natural Sciences (CoNAS), Makerere University in collaboration with the National Fisheries Resources Research Institute (NaFIRRI) and partners – International Development Research Centre (IDRC) held the NutriFish project product launch and dissemination event. The event was presided over by the Minister of State for Fisheries, Hon. Hellen Adoa represented by the Ag. Director, Directorate of Fisheries Resources, Ministry of Agriculture, Animal Industry and Fisheries (MAAIF), Mr. Tom Mukasa Bukenya. It was graced by Ms. Mercy Rurii, Programme Officer at the IDRC of Canada and a number of dignitaries from the agricultural and fisheries sector including the Director General of NARO represented by Ms. Winnie Nkalubo from NaFIRRI.
Remarks by the PI
Presenting an overview of the project and achievements registered, the NutriFish Principal Investigator, Dr Jackson Efitre emphasized the importance of SPFs in addressing nutritional deficiencies and improving livelihoods of vulnerable communities.
He appealed for the inclusion of small fishes and fish products into the national nutrition/health interventions including school feeding programs and supplemental feeding in malnutrition units at health facilities. He expressed gratitude to the funders of the project noting that it had greatly transformed livelihoods of vulnerable communities in the country. “Sincere appreciation to our implementing partners NaFIRRI, McGill University and Nutreal Ltd., who worked closely with us to effectively implement the NutriFish project. We also thank the different Government Ministries, Departments, Agencies, the donors, the private sector, and community members – who supported us throughout the project implementation.”
Testimonies by the beneficiaries
Sharing experiences, the beneficiaries appreciated the project team and funders noting that the interventions had improved the quality of their operations subsequently increasing their profits and transforming their livelihoods. “I was born at the lake and I have grown up there but I had never eaten Mukene for several reasons, but mainly due to poor preservation methods. Following the interventions by the NutriFish Project, my attitude towards Mukene changed and I now own a Mukene business which has greatly transformed my life. With the skills acquired from the trainings conducted by NutriFish, we are now able to produce and sell quality Mukene and our profits have increased. Out of the 14 members in my group, 5 of us bought boats and this has increased our income from UGX500,000 to UGX3,000,000 per month per individual,” Mercy Betty, Mukene trader at Ntoroko Fish Landing Site. According to Patrick Chakcon, a fish trader from Dei Landing Site in Pakwach, the solar tent drier has helped improve the quality of their products. “Initially, we relied mainly on open drying which is time wasting and not secure. With the introduction of the solar tent drier, many fish dealers now have time for other activities. We thank the project team and the funders for this intervention. We however appeal for more units because what we have at the moment can only dry 500kgs out of the 5000kgs harvested per day.”
Before the project, Ms. Tereza from Kikondo in Buikwe district was experiencing a lot of challenges and at some point got thoughts of suicide. She is so grateful for the intervention because she now works and can support her family.
Remarks by the Minister of State for Fisheries
In her address presented by the Ag. Director, Directorate of Fisheries Resources, Ministry of Agriculture, Animal Industry and Fisheries, Mr. Tom Mukasa Bukenya, the Minister of State for Fisheries, Hon. Hellen Adoa commended the project team for the initiative. She also appreciated the funders for supporting the project. Highlighting the value of fish in terms of exports which now stands at approximately USD177 million, the Minister said Government had prioritized fish in the agricultural sector strategic plan as a flagship commodity for investment and development in line with National Development Plan (NDPIII). “Through the Agricultural Sector Strategic Plan, promoting Small Pelagic Fishes is one of the priorities of the Ministry of Agriculture, Animal Industry and Fisheries to address issues of hunger, malnutrition and food security and improve livelihoods of the fishing communities. I’m happy that the project has come up with tangible solutions to deal with some of these challenges including unsustainable harvest and post-harvest losses.” The Ministry implored the project team share the findings widely through various regional bodies.
Remarks by the Vice Chancellor
In his speech delivered by the Deputy Principal of CoNAS, Prof. Juma Kasozi, the Vice Chancellor of Makerere University, Prof. Barnabas Nawangwe congratulated the NutriFish Project team upon achieving the set objectives. “On the 27th June 2019, I had the honour of officiating at the launch of the innovative Harnessing dietary nutrients of under-utilized fish and fish processing by-products to reduce micronutrient deficiencies among vulnerable groups in Uganda – NutriFish Project. Today, I am happy to witness the launch of the project innovations and products. NutriFish brought together pillars of knowledge (research and academia) and the Private sector and addressed issues of maternal and child health, nutrition, and poverty reduction through a Public-Private-Partnership approach.” The Vice Chancellor noted that the project activities were in line with Makerere’s current Strategic Plan (2020 -2030) which aims at transforming the University into a research-led institution with a multi-faceted research agenda; and enhanced engagement with industry and the business sector. “As University management, we are happy that we provided conducive working conditions and facilities that enabled NutriFish and her partners to successfully implement project activities. On behalf of Makerere University Management, I extend our appreciation to the funders of the project and the implementing partners.”
Remarks by the IDRC representative
In her remarks, Ms. Mercy Rurii, Programme Officer at the International Development Research Centre of Canada commended NutriFish project as timely intervention that would largely address the challenge of malnutrition in the region. “Malnutrition has negative impact on the cognitive development of children and poses unnecessary burden on the healthcare system. Money that would be spent on other productive sectors goes into healthcare as a result of the many diseases arising from malnutrition, and this becomes a very crippling development challenge. The project team has come up with practical solutions to address this challenge. On behalf of IDRC, we commend the project team for these interventions.”
On behalf of the Principal, CoNAS, Prof. Winston Tumps Ireeta, the Deputy Principal, Prof. Juma Kasozi expressed gratitude to the funders and project partners. He appreciated the project team for the timely initiative that emphasized community engagement in line with Makerere University Strategic Goal 4.
The event featured a panel discussion on National and regional initiatives for addressing fisheries management challenges, moderated by renowned TV talk-show host, Mr. Patrick Kamara. Panelists included Mr. Tom Bukenya, Ag. Director, Directorate of Fisheries Resources, MAAIF; Ms. Joyce Ikwaput Nyeko, Deputy Executive Secretary, Lake Edward and Albert Fisheries and Aquaculture Organization Entebbe; Ms. Nelly Badaru, Gender Expert and Independent Consultant; and Mr. Boaz Musementa from the Office of the Prime Minister. They called for development of quality assurance standards for Mukene products to penetrate the international market. They also called for inclusion of women in decision making processes, strengthening of regional cooperation to minimize trans-boundary conflicts and harmonization of the legal and policy frameworks.
The event also featured an exhibition of several products developed under the NutriFish project.

A team of researchers from Makerere University has presented findings of a study on the persistent poor performance in Biology in national examinations to senior officials at the Ministry of Education and Sports.
The findings were shared during a dissemination meeting attended by the Ministry’s top management, led by Permanent Secretary Kedrace Turyagenda.
The study, commissioned by the Ministry in 2023, was conducted by researchers from the College of Natural Sciences (CoNAS) and the College of Education and External Studies (CEES). It was spearheaded by Prof. Fredrick Muyodi as Principal Investigator, alongside Assoc. Prof. Josephine Esaete (Co-Principal Investigator) and Prof. Arthur Tugume among others.
Titled “Examining the Factors Accounting for Poor Academic Performance in Biology in Uganda’s National Examinations,” the study covered all regions of the country, engaging more than 5,200 respondents across 100 districts through surveys, interviews, and observations.
Key findings
The research identified limited field-based learning and poor digital access as the most critical and consistent challenges affecting both Ordinary and Advanced Level students across all regions.
At Advanced Level, the lack of project-based learning was also cited as a significant constraint. Learners reported limited engagement with Biology beyond the classroom, a factor that weakens conceptual understanding and application in examinations.
The study further highlighted the role of community attitudes and perceptions in shaping student performance in the subject.
Recommendations
The researchers recommended increased investment in field-based learning, including field trips and project work, as well as expansion of digital infrastructure to improve access to learning resources.
Other proposed measures include strengthening school laboratory facilities, enhancing teacher capacity through continuous professional development, promoting student engagement through academic clubs and mentorship programmes, and fostering stronger family and community support for science education.
Next steps
The research team is seeking funding to pilot targeted interventions, particularly in regions most affected by the challenges identified, and to develop a monitoring and evaluation framework to guide implementation.
The findings are expected to inform policy and interventions aimed at improving Biology performance and strengthening science education in Uganda.

Transforming Food Waste into Clean Energy: Makerere University Researchers Equip Mbarara City Residents with Biogas Production Skills
*****Led by Dr. Patience Tugume from the Department of Plant Sciences, Microbiology and Biotechnology at Makerere University, a project titled “Bio-innovation of biogas, biofertilizer, and biopesticide through the utilization of bio-waste” is promoting the transformation of household food waste into biogas and other valuable bio-products. The project team disseminated the research findings to stakeholders in Mbarara City on 15th April 2026.
About the Project
A one-year bio-innovation initiative focused on converting household food waste into biogas, biofertilizer, and biopesticides has yielded promising results in improving access to clean energy and promoting sustainable agricultural practices in peri-urban communities of Mbarara City.
The project, implemented by Makerere University in collaboration with Frevasema Ltd in Mbarara, was supported by UNESCO and the International Development Research Centre (IDRC) – Canada through the Organization for Women in Science for the Developing World (OWSD). Launched in January 2024, it is led by Dr. Patience Tugume from the Department of Plant Sciences, Microbiology and Biotechnology at Makerere University.
The initiative has been implemented across five divisions of Mbarara City – Kakoba, Kamukuzi, Nyamitanga, Biharwe, and Nyakayojo – with additional field trials conducted in Masha Sub-county, Isingiro District.
Objectives of the project
The central aim of the project was to demonstrate how biodegradable household waste can be transformed into useful products, particularly biogas for cooking, as well as organic biofertilizers and biopesticides for improved crop production.
Key objectives of the project included: establishing a spin-off centre of bioreactors at the business partner institution (Frevasema Ltd) to demonstrate sustainable production of biogas, biopesticides and bio-fertilizers; training and equipping women and youth with hands-on skills in biogas production and usage; evaluation of yields from different bio wastes; and creation of linkages between academia, the private partner and rural communities in up-scaling production of biogas, biopesticides and bio-fertilizer from household/urban biodegradable wastes.
Key Activities and Dissemination of Project Findings
The project team conducted a survey to assess community perceptions and the factors influencing the adoption of biogas as an alternative cooking energy source in peri-urban areas of Mbarara City. In addition, biodigester tanks were constructed at FREVASEMA Ltd to support training and knowledge transfer activities.
Field experiments were undertaken in Masha Sub-county, Isingiro District to evaluate the effectiveness of an integrated biofertilizer–biopesticide. Further experiments to assess biogas yield from different types of food waste were conducted at Makerere University.
The team also developed an integrated biofertilizer–biopesticide by enhancing bioslurry, a by-product of biogas production, with plant extracts known for their pesticidal properties. The effectiveness of this product was tested on the growth performance of green pepper, cabbage, and eggplant.
In line with one of the project objectives, the team also conducted hands-on training in biogas production from food waste for 35 students and 6 staff members of MAMITA Technical and Business Institute.
Dissemination workshop
On 15th April 2026, the project team led by Dr. Tugume held a dissemination workshop to share findings with stakeholders and discuss strategies for scaling up the outcomes.
Findings from the research highlight the strong potential of biogas in contributing to sustainable energy solutions, improving livelihoods, and enhancing environmental conservation through proper food waste management.
Key research findings
- The application of integrated biofertilizer–biopesticide presents a viable alternative to scarce, expensive, and environmentally harmful inorganic fertilizers for enhancing vegetable productivity.
- The study revealed that approximately 90.7% of respondents depend on charcoal and firewood as their primary cooking fuel.
- While 92.1% of respondents were aware that biogas is produced from animal and plant materials, only 7.9% recognized that food waste can also serve as a feedstock, indicating limited awareness of its full potential.
- Banana and potato peels, as well as posho and potatoes leftovers, and green vegetable trimmings, were identified as the most commonly generated food wastes.
- A majority of respondents strongly agreed that biogas is a cleaner and more sustainable energy alternative compared to firewood.
- Key barriers to biogas adoption included inadequate technical knowledge, safety concerns regarding biogas systems, and the high costs of constructing and maintaining biodigesters.
- The extremely low adoption rate of biogas technology (0.3%) indicates significant underutilization despite its potential to mitigate fuel shortages.
- There is a prevailing perception that biogas is suitable for cooking and can effectively replace biomass fuels, given the availability of sufficient feedstock from household food waste, human waste, and animal manure.
- Potato and posho residues were identified as the most suitable primary feedstocks for biogas production due to their high nitrogen content, volatile solids, and total organic carbon (TOC).
- Effective collection and proper segregation of food waste are essential for ensuring a consistent and uncontaminated supply of feedstock for biogas production systems.
- Further research is recommended on integrated biogas systems that combine anaerobic digestion with other renewable energy technologies, such as solar energy or bioelectrochemical systems, to improve overall energy recovery efficiency.
- Vegetables treated with the integrated biofertilizer–biopesticide consistently exhibited superior performance across all growth parameters compared to those treated with inorganic fertilizers (including 5% cypermethrin pesticide) and untreated controls.
Stakeholder engagement and appreciation of the initiative
During the dissemination workshop, Dr. Patience Tugume, the Principal Investigator, expressed gratitude to UNESCO and the International Development Research Centre (IDRC)-Canada, through the Organization for Women in Science for the Developing World (OWSD), for funding the project. She appreciated the research team composed of Dr. Asiimwe Savina, Prof. Maud Kamatensi-Mugisha, Prof. Bazirake Byarugaba, Ms. Catherine Kiconco and Mr. Muhumuza Robert for their contribution. She equally appreciated all participants for contributing valuable information to the study.
Stakeholders commended the project for its relevance and community impact.
Prof. Bunny Lejju Julius from Mbarara University of Science and Technology, appreciated the project team for developing an innovation that directly addresses community needs and aligns with the principles of the competency-based curriculum, particularly the translation of academic knowledge into practical application. He advised that sustainability of the initiative could be strengthened through a multiplier approach, where the trained learners cascade the knowledge to other community members. He further recommended the identification of institutional staff who can undergo training at the spin-off centre and subsequently serve as trainers within their respective communities.
The portable biodigester system was recognized as a simple, affordable, and practical technology with the potential to provide a cost-effective alternative to charcoal and electricity. Participants noted that while resistance to change remains a challenge, continuous awareness creation is essential to promote adoption and facilitate behavioral change.
Mbarara District Forest Officer, Ms. Ainembazi Joses, highlighted the importance of the biogas production project in environmental conservation. She noted that the initiative contributes to reducing deforestation by offering an alternative to firewood and charcoal, thereby supporting sustainable natural resource management.
The Local Council Chairperson of Mailo-Biharwe Division, Mr. Didas Katabazi, appreciated the project team for the innovative work and its potential benefits to the community. He pledged to use his office to advocate for increased government support to scale up the project.
The Resident City Commissioner of Mbarara City expressed concern over the rising levels of deforestation in the district and commended the Principal Investigator for spearheading the innovation. He reaffirmed the government’s commitment to supporting science and innovation. He emphasized the importance of integrating environmental protection with agricultural productivity, explaining that food security remains a national priority. He further noted that the project demonstrates the concept of waste valorization, where organic waste is transformed into valuable products such as biofertilizers and biopesticides, thereby enhancing agricultural productivity. He pledged to engage the Office of the President to support wider dissemination of the project outcomes. Additionally, he encouraged the trained students to act as ambassadors of the project by sensitizing communities on the benefits of biogas as an alternative source of cooking energy.
Way forward
- The government should invest in constructing bio digesters for households at subsidized prices or offer them financial assistance to cater for bio digester construction.
- Awareness campaigns about the production and use of biogas and associated benefits should be intensified in communities to dispel the negative perceptions.
- Provision of technical training in operating and maintenance of biogas installations should be conducted.
- Sorting of wastes at household level should be emphasised to separate biodegradable from non biodegradable ones.
- The integrated bio-fertilizer-bio-pesticide is an effective, sustainable strategy to increase vegetable productivity while improving soil health in nutrient-limited soils.
- The project recommends adoption of bio-fertilizers (e.g., bio-slurry) which are affordable and can be made from kitchen and market waste to reduce dependence on expensive chemical fertilizers to improve crop growth while controlling pests safely in addition to being safe for humans and the environment.
Donation of portable biodigester systems
As part of the commitment to translate research into tangible benefits, the project awarded two women and MAMITA Technical and Business Institute with portable biodigester systems for installation and use in their households and institution respectively. These systems will serve as demonstration units within the community showcasing the practicality, affordability, and impact of clean energy solutions at the household level.
