Constraints and promising interventions to strengthen fish seed systems in Sub-Saharan Africa: Evidence from Ghana

CONTEXT Aquaculture has surpassed capture fisheries in terms of production and is among the fastest growing food sectors. It has great potential to contribute to food security and nutrition, poverty reduction, jobs, and environmental sustainability. Fish seed is increasingly considered to be a major driver and disabler of aquaculture development. However, little is known about how fish seed systems operate, their challenges and opportunities, or entry points for strengthening them. OBJECTIVE This study analyzes primary data on the challenges and opportunities faced by various actors along the fish seed chain, documents the lessons from a fish seed project (Ghana Tilapia Seed Project, 2019–2022), and provides an analysis of entry points for strengthening fish seed systems. METHODS Using an analytical framework that tracks germplasm base, seed production and quality, seed availability and distribution, and the information flow along the fish seed value chain, we analyze the case of Ghana, the top producer of farmed tilapia in sub-Saharan Africa. The study uses a mixed-methods approach, including value chain analysis, action-oriented research methods, and statistical analysis of survey data. RESULTS AND CONCLUSIONS Findings indicate that the initial rapid growth in tilapia production in Ghana was partly due to an improved local strain released in 2004; however, the recent stagnation is largely caused by seed-related issues (poor maintenance and improvement of germplasm base, seed quality and availability, lack of information and coordination, and lack of enforcement of regulations). This study highlights the successes and lessons learned from the Ghana Tilapia Seed Project on broodstock distribution, training on fingerling production, establishment of nurseries, and training of fish farmers. The lessons highlight the need for policy changes and capacity building related to strain development and broodstock management. SIGNIFICANCE These findings fill the large gap in evidence on the functioning of fish seed systems and how to strengthen them. They can directly inform ongoing country-level efforts and programs aiming to develop aquaculture.

The characteristics of community seed schemes for grains and legumes: Insights from northern Nigeria

CONTEXT Despite the significant roles that intermediary seed systems play in the supply of quality seed in developing countries, including Africa South of the Sahara, the knowledge gap remains generally substantial regarding the general characteristics and seed quality assurance performance of intermediary seed systems like community seed schemes (CSS), which still predominantly operate outside the formal seed systems. OBJECTIVE We aim to narrow the knowledge gap on seed production practices implemented by CSS and their economic characteristics, the extent of seed quality assurance achieved, and potential challenges CSS is facing. METHODS Using primary survey data of seed producers of key grains (maize, rice, and sorghum) and legumes (cowpea and soybean) from 380 CSS in Kano state in northern Nigeria, we qualitatively assess seed production characteristics, financial structures of their seed production, aspects of quality assurance measures they engage, and potential roles of external support like training on their implementation of these quality assurance measures. RESULTS AND CONCLUSIONS We discovered that many of the interviewed CSS have emerged endogenously, taking up seed production to address the challenges in access to quality seed in their locality. Their seed production has often grown into viable businesses that have provided potentially significant additions to their incomes. Oftentimes, these CSS implemented some seed quality assurance measures, including making closer visual checks of seed, checking germination rates, and bagging/packing seed, among others. However, fuller seed quality assurance may be significantly skill-intensive, and most CSS still do not implement many of the recommended measures under some of the intermediary quality assurance standards like quality declared seed. Our qualitative assessment suggests that future support for CSS can focus on technical support to raise the ability to engage in broader categories of quality assurance activities in financially viable ways and to improve the awareness and knowledge of different varieties and access to early generation seed. SIGNIFICANCE The quality assurance provided by existing community seed schemes in Nigeria may be relatively limited, particularly in terms of proper maintenance of seed production field and the quality of original varieties that they intend to multiply. Providing external support through training and technical assistance may be an effective way to transform community seed schemes into critical providers of seed quality assurance in intermediary seed systems and fill gaps in the formal seed system.
