The CGIAR Initiative on Aquatic Foods aimed to build the resilience of aquatic food systems and unlock their full potential by scaling research and innovations. Working closely with research partners in fisheries and aquaculture, civil society, industry, and governments, the Initiative contributed to the reduction of greenhouse gas emissions from the production of aquatic foods, and enhance ecological and social resilience through development and dissemination of improved fish strains, better management practices, integrated fish-rice production systems, and fish-friendly irrigation systems.
Imagining island food system futures with Indigenous foods: A tok stori on the experiences and potential of traditional food systems in provinces of Solomon Islands
(Brief, 2024-12-31) Wate, Jillian Tutuo; Tikai, Pitakia; Lodu, Esther; Vaike, Lyn; Saeni-Oeta, Janet; Bennet, Gregory; Eriksson, Hampus
Transition to unhealthy food choices and lifestyles is causing health problems for Solomon Islanders. Due to these circumstances, a tok stori was organized in 2023 to start addressing the following question: “what does a vision for a healthy and safe food system comprise?” (Tutuo et al. 2023). To follow up on these discussions, WorldFish and the Kastom Gaden Association (KGA) organized a second series of forums called Island Food Systems in Transition: Strengthening Indigenous Food Systems in Solomon Islands. The forums were hosted in Gizo, Western Province, on June 13, 2024, and in Buala, Isabel Province, on August 14, 2024 . These forums brought together rural actors and key stakeholders (i) to talk about traditional farming and aquatic foods under a nutrition-sensitive approach and (ii) to listen to ideas about what the future of food systems in Solomon Islands could look like at the provincial level.

Sustainability impacts of ecosystem approaches to small‑scale aquaculture in Bangladesh
(Presentation) Rossignoli, Cristiano
Aquatic food is vital for food security in Bangladesh, where fish accounts for up to 60% of animal-based protein intake. As the world’s 5th largest aquaculture producer, the sector has expanded significantly, supporting livelihoods and food security. Small-scale aquaculture, particularly in inland ponds, dominates production, contributing 94% of national output. Around 4.3 million rural households (20% of the population) manage homestead ponds, typically 0.08–0.10 hectares in size. This presentation introduces the EcoPond Model, along with the methodology and key findings, highlighting how ecosystem-based approaches enhance sustainability, improve resource efficiency, support biodiversity, and strengthen climate resilience in small-scale aquaculture.
Development of an economic trait prioritization for Tilapia in Nigeria: Survey (deliverable 2) progress summary
(Internal Document, 2024-06-26) Cole, Steven; Adams, Chris; Byrne, Tim
Deliverable 2 (participatory survey and typology analysis) uses economic weights calculated in Deliverable 1 (economic modelling) to capture trait preference and typologies based on survey feedback from key stakeholders. In Tilapia, these surveyed stakeholders will include farmers and hatchery operators, but may also encompass other value chain actors, including wholesalers /retailers depending on primary breeding objectives. The Deliverable 2 output will be a set of trait preference coefficients that fine-tune (up or down) economic values from Deliverable 1 based on input from each typology. Applying these trait preference coefficients to economic values help in understanding stakeholder’s trait improvement preferences and ensures the systematic integration of stakeholders’ preferences into selection and breeding decisions to support faster and more balanced rates of genetic gains and deliver improved fish species that meet industry needs.

The Ministry of Fisheries and Marine Resources (MFMR) fisheries policy aims to facilitate sustainable use of inshore and inland fisheries for rural men and women that access, use and benefit from them, through improved preservation, market access and enhanced livelihood opportunities. Accordingly, the MFMR has carried out research to identify challenges and opportunities in the smoked fish value chain. This brief summarises some of the findings, including the origins and development of Shortland Islands smoked fish production from a traditional subsistence form to a marketable commodity. The focus is on the process from fish landing through to sales, and the gender differentiation of roles in production and marketing.
Impact assessment of aquaculture in small reservoirs pilots in northern Ghana: a baseline technical report
(Report, 2024-12-30) Zane, Giulia; Buisson, Marie-Charlotte; Appiah, Sarah; Asare, G.
The CGIAR Resilient Aquatic Foods Systems Initiative (RAqFS) aims to enhance the resilience of aquatic food systems by addressing systemic challenges. As part of this initiative, the International Water Management Institute (IWMI) partnered with the CSIR Water Research Institute and the Fisheries Commission of Ghana in 2023 to co-design and implement an aquaculture pilot in four small reservoirs across four communities in the North-East Region of Ghana. The pilot project engaged groups of 10-15 individuals in each community, ensuring the inclusion of youth and women, and provided them with technical training and essential inputs to undertake tilapia cage culture. The groups cultivated fish in August-September 2023 and completed the first cycle in September-October 2024.
Predicting turbidity dynamics in small reservoirs in Central Kenya using remote sensing and machine learning
(Journal Article, 2025-02) Steinbach, S.; Bartels, A.; Rienow, A.; Kuria, B. T.; Zwart, Sander Jaap; Nelson, A.
Small reservoirs are increasingly common across Africa. They provide decentralised access to water and support farmer-led irrigation, in addition to contributing towards mitigating the impacts of climate change. Water quality monitoring is essential to ensure the safe use of water and to understand the impact of the environment and land use on water quality. However, water quality in small reservoirs is often not monitored continuously, with the interlinkages between weather, land, and water remaining unknown. Turbidity is a prime indicator of water quality that can be assessed with remote sensing techniques. Here we modelled turbidity in 34 small reservoirs in central Kenya with Sentinel-2 data from 2017 to 2023 and predicted turbidity outcomes using primary and secondary Earth observation data, and machine learning. We found distinct monthly turbidity patterns. Random forest and gradient boosting models showed that annual turbidity outcomes depend on meteorological variables, topography, and land cover (R2 = 0.46 and 0.43 respectively), while longer-term turbidity was influenced more strongly by land management and land cover (R2 = 0.88 and 0.72 respectively). Our results suggest that shortand longer-term turbidity prediction can inform reservoir siting and management. However, inter-annual variability prediction could benefit from more knowledge of additional factors that may not be fully captured in commonly available geospatial data. This study contributes to the relatively small body of remote sensing-based research on water quality in small reservoirs and supports improved small-scale water management.
Baseline study: Digital fisheries and scaling postharvest technologies to reduce aquatic food waste and loss in coastal Kenya
(Dataset) Manyise, Timothy; Brako Dompreh, Eric
The baseline study on Digital Fisheries and Scaling Postharvest Technologies to Reduce Aquatic Food Waste and Loss in Coastal Kenya provides a comprehensive dataset on the socio-economic characteristics, fisheries management practices, and postharvest challenges faced by fisherfolk and fish traders. Conducted across the coastal counties of Mombasa, Kwale, Kilifi, Lamu, and Tana River, this study employs a mixed-methods approach to assess the adoption of postharvest technologies, digital tools, access to resources and participation, and infrastructural gaps affecting fisheries productivity and fish loss and waste. The findings highlight critical barriers, including limited awareness of digital technologies, inadequate cold storage facilities, and financial constraints that contribute to significant postharvest losses. The dataset serves as a foundational resource for policymakers, researchers, and development practitioners seeking to enhance fisheries management, strengthen fisheries value chains, and promote sustainable aquatic food systems in Kenya’s coastal regions.
Introducing the Nusatupe innovation hub – showcasing the best of the sustainable island food systems
(Video) Palmer, Neil; Eriksson, Hampus; Wate, Jillian Tutuo; Bennet, Greg; Saeni-Oeta, Janet
It must be one of the most unusual and remote research outposts within CGIAR: The Nusatupe innovation hub inhabits the southwestern corner of the tiny coral atoll of Nusatupe, in Western Province, Solomon Islands. Surrounded by aquamarine waters, and with a Marine Protected Area close by, Nusatupe has been the site of a WorldFish research station for 40 years or so – remote from the rest of the world but very close to the lives of Solomon Islanders. Its recent transformation from a research station into an innovation hub is part of a much needed reinvention of the facility, to ensure it is responsive to the needs of local institutions, fishers, farmers and youth. It now undertakes and showcases a range of activities from coral replanting to fish preservation and handling, to indigenous food gardens, bringing in visitors from around Solomon Islands to show what nutritious, sustainable island food systems can look like.
Big Data for Small-scale Fisheries - Peskas in Timor-Leste
(Video) Palmer, Neil; Tilley, Alexander; Sozinho, Villiam
Small-scale coastal fisheries in Timor-Leste (East Timor) are a vital source of food and income for thousands of people. But the lack of data on where fishers go and how much they catch has made it challenging for the government to develop policies to support and sustain the sector. Enter Peskas, a groundbreaking digital catch monitoring system developed by WorldFish with support from the Royal Norwegian Embassy in Jakarta, Pelagic Data Systems, and the CGIAR Initiative on Aquatic Foods. Peskas captures and shares critical fish catch data that enables smarter decision-making, and more sustainable management of coastal fisheries. In this short film you’ll learn all about how the innovation works, set in the stunning surroundings of Timor-Leste. Peskas is now being scaled up to four African countries with the support of UK International Development. Shot and produced by Neil Palmer for WorldFish.

Report on the progress of selection of TiLV disease resistance
(Internal Document, 2024-12-31) Izadi, Fariba
Infectious disease is one of the main issues threatening the success and sustainability of Nile tilapia production. The Tilapia Lake Virus (TiLV) has emerged as a major threat to Nile tilapia. Combining the new trait data with genomic tools identified several significant QTLs throughout the Nile tilapia genome. In addition, the first tests of genomic selection have been performed in the GIFT breeding program, which promises to increase the response to selection while also reducing the inbreeding rate compared with a pedigree-based approach.

Community fish refuge (CFR) pond monitoring: surface and groundwater study at Sras Ang CFR, Prey Veng Province, Cambodia
(Report, 2024-12-30) Oeurng, C.; Sok, T.; Hout, M. H.; Ich, I.
This technical report delves into the essential task of gathering validation data, focusing on surface and groundwater related data monitoring through the deployment of field equipment. The primary objective is to comprehensively monitor surface water and groundwater levels, along with rainfall, on a regular basis. This hydrologic monitoring initiative is conducted within the context of a case study centered on rice-fish systems, specifically community fish refuges (CFRs) in Prey Veng Province, Cambodia. The selected study area, Prey Veng Province, features a network of community fish refuges. The chosen pond, "Sras Ang", was converted into a fish refuge in 2010 and has a protected status during both wet and dry seasons. The monitoring approach included the installation of instrumentation for continuous monitoring of surface water and groundwater levels, as well as rainfall. Groundwater gradient assessments were conducted, and soil data was collected for further analysis. The collected data was used to create a preliminary water balance assessment, considering factors such as effective rainfall, surface water runoff and groundwater recharge. The study also incorporated anthropogenic influences, like water abstractions and discharges. The project involved site visits, community meetings, and the establishment of monitoring plans. Rainfall data, potential evaporation rates, groundwater levels, and pond water levels were collected and analyzed to understand the hydrological dynamics of the area.
