    Abstract Feed accounts for 60–80% of tilapia production costs, and high feed cost and limited feed access are major issues faced by fish farmers. A potential solution is for farmers to produce their own feeds using cheaper and locally available ingredients. This paper evaluates the feed formulation training implemented in Ghana as part of the Fisheries Commission's activities under the Ghana Aquaculture for Food and Jobs program. This paper analyzes baseline and follow-up survey data using difference-in-difference estimation and analysis of covariance. One year after the training, results show positive impact on the farmers' knowledge of feed formulation, quantity of feed formulated, feeding and management practices, productivity, and income. Feed formulation training encouraged more farmers to formulate their own feeds and maintained or increased total feeds used in their facilities from 2018/2019 to 2020/21. Among the farmers who did not receive training, feed formulation activities and feed quantity used reduced from 2018/19 to 2020/21. A common practice is the use of locally available quality commercial feed as starter feed for smaller fish and own-formulated feeds as a complement for or alternative to commercial growout feeds for bigger fish. Especially when constrained by lack of funds, many farmers reduce the use of commercial feeds and formulate their feeds using cheaper and locally available raw materials to maintain similar levels of feeding intensity. Feed formulation acts as an important coping strategy in the context of small-scale farmers with limited financial resources. This study recommends scaling out feed formulation training and expanding research on optimal fish nutrition using locally available and low-cost raw materials, in combination with commercial feeds, to maximize productivity and incomes for farmers.

    Abstract Globally, countries have resorted to social distancing, travel restrictions and economic lockdowns to reduce transmission of COVID-19. The socioeconomic costs of these blunt measures are expected to be high, especially in sub-Saharan Africa where many live hand-to-mouth and lack social safety nets. Social Accounting Matrix multiplier model results show that Ghana's urban lockdown, although in force for only three weeks in April 2020, has likely caused GDP to fall by 27.9% during that period, while an additional 3.8 million Ghanaians temporarily became poor. Compared to the government's revised GDP growth rate of 1.5% for 2020, the model predicts a contraction of 0.6 to 6.3% for 2020, depending on the speed of the recovery. The US$200 million budgeted for Ghana's Coronavirus Alleviation Program will close only a small part of the estimated US$ 2.3 billion GDP gap between the fast recovery scenario and government's revised GDP trajectory.

    Abstract This paper provides empirical evidence on the processes and strategies of encouraging women's entrepreneurship and the impact of women's entrepreneurship on their empowerment in the context of emerging aquaculture value chains in Sub-Saharan Africa. We do this by analyzing two survey rounds with 500 fish-producing household, A-WEAI, 11 in-depth interviews, and 7 FGDs of women in six major producing regions in Ghana. Baseline data show that 9% of fish farm managers/owners were women; and women contributed 16% of labor days. Gender norms persist around aquaculture as men's job; only few women entered aquaculture. Once women entered aquaculture, they were at least as productive and profitable as men on average. Women aqua-entrepreneurs were at least as empowered as the men aqua-entrepreneurs. Being able to break the popular perspective and gender norm that "aquaculture is a men's job" and still started and operated aquafarms, these women were empowered to begin with. Their engagement in aquaculture had benefited them and empowered them more. The majority of the spouses of men aqua-entrepreneurs were not involved in aquaculture, and had lower empowerment score and were less likely to be empowered than the women and men aqua-entrepreneurs. Most of them indicated that they would like to get involved in aquaculture as it will generate more income. We discuss in this paper opportunities and strategies to involve more women in fish-producing households and to encourage new female farmers to enter aquaculture and other aspects of the value chains.

    Abstract Aquaculture in Ghana is experiencing tremendous growth, led mainly by large-scale commercial cage operators. A major objective of the government and its partners is to ensure that this rapid growth is sustainable and includes small-scale farmers and poor rural producers. This paper evaluates the aquaculture trainings implemented in six main tilapia-producing regions in Ghana as part of the Ghana Tilapia Seed Project. The impact evaluation is designed as a cluster randomized controlled trial, with half of the producing districts randomly-assigned as the treatment and the rest as the control, complemented by qualitative interviews. One year after the trainings, results show positive impacts on the adoption of good record-keeping, water management, and some biosecurity practices, and on productivity and incomes. In terms of mechanism, improved management practices resulted from reducing overstocking, reducing inbreeding, maintaining water level for fish ponds, regular pond clearing and establishing physical barriers, following advice and recommendations on feeding practices, and complementing feeding practices with farmers’ own feed formulation. Half of the trained farmers experienced lower fish mortality, faster growth, and heavier fish at harvest. Marketing and processing advice through the trainings and complementary FishConnect WhatsApp platform likely contributed to higher incomes, although the platform's coverage and regular updating can be improved.

    Abstract Over the past decade, the aquaculture sector in Ghana has experienced tremendous growth—driven mainly by large-scale cage aquaculture. Pond aquaculture, traditionally extensive and with limited external inputs, has been transforming over the same period. Farm profitability was wide-ranging, between −12.00 and 46.00 Ghanaian cedi (GHC) per square meter (m2), with an average of GHC 8.82/m2 for farmers active in 2019. Despite wide variability in production and profits, the majority of farmers experienced positive profits—on average, GHC 3.24 per kilogram of tilapia produced, or a 27% profit margin. Farmers who adopted good aquaculture practices and intensified their production have high productivity and positive profits. Nonetheless, the cost to produce 1 kg of tilapia in Ghana (roughly US$1.51 on average) was much higher than in other major tilapia-producing countries (averaging roughly US$0.78 to 1.29). COVID crisis further affected fish farmers: 54% experienced difficulties in accessing inputs, 56% experienced difficulties selling their fish, and farmgate fish prices went down in April–August, although slowly bounced back by end of 2020. Improving the competitiveness and resilience of Ghanaian tilapia sector will require improved seed, increased adoption of good management practices, lower-cost quality feed, and enabling policies and regulations.

    Abstract Ghana has a long history of intervening in food markets to balance consumers’ expectations of low and stable food prices, farmers’ demands for high farmgate prices, and traders’ demand for predictability in seasonal price patterns. However, government interventions may also alter the behavior of markets and alter incentives or risks for all market actors. The Planting for Food and Jobs (PFJ) initiative, launched in 2017, signaled a renewed commitment from government to agriculture and is Ghana’s flagship strategy for boosting smallholder production, strengthening market linkages, and developing value chains. Given this significant policy shift, we examine agricultural commodity price patterns before and after 2017 to identify potential structural shifts in price behavior in maize, tomato, and onion markets, three key sectors targeted by PFJ. Results show maize and tomato prices drop below their long-term trend under PFJ, but not onion prices. Tomato and onion prices exhibit smaller seasonal price variations. These results are indicative of a structural shift in food markets, although further analysis is required to conclusively attribute these changes to PFJ.
