Projects

The 3-year program titled “Accelerating aquaculture development in Ghana through sustainable Nile Tilapia seed production and dissemination,” (TiSeed in short) was launched on February 2019 to address issues in the tilapia seed and extension system to improve productivity and profitability of tilapia cage and pond farming in Ghana, with particular focus on women and youth small-scale fish farmers.

The program runs from 2019 to 2022 and is being implemented by a consortium of international and local research institutes, led by IFPRI, supported by the Water Research Institute, (WRI) of the Council for Scientific and Industrial Research (CSIR) in Ghana, KIT Royal Tropical Institute in the Netherlands, and WorldFish. Other partners are Fisheries Commission (a government institution) and two private hatcheries (S-HOINT Ltd. and Crystal Lake Ltd.).

The program is working with other key players in the industry, including Raanan Fish Feed West Africa Ltd., Aller Aqua Feed Ghana Ltd., Ghana Aquaculture Association, National Fish Pond Farmers Association, Flosell Farms, West African Fish Ltd., National Aquaculture Technical Committee, Environmental Protection Agency. The program is a research grant funded by the Government of Netherlands and the CGIAR Research Programs on Policies, Institutions and Markets (PIM) and Fish Agri-Food Systems (FISH). This program is among the nine (9) research proposals selected and awarded through the Netherlands-CGIAR research programme on seed systems development.

Does ICT-based aquaculture extension contribute to greater adoption of good management practices and improved incomes? Evidence from Ghana

This paper aims to assess the coverage and contribution of different information and communication technology (ICT) tools (mobile phone, WhatsApp platform, television, and radio) in the dissemination of aquaculture and market information to fish farmers in Ghana. Data from a 2021 survey of 391 active fish farmers were analyzed using propensity score matching, inverse probability weighted regression adjustment, and multivariate probit regression models. Mobile phone (phone-based app, internet search, or social media) is the most used ICT tool for aquaculture advice, followed by television programs. Results show that receiving aquaculture information through ICT tools has a positive and significant average treatment effect on the adoption of good management practices, farm productivity, and farmers’ income. Farmers receiving aquaculture information from mobile phone and television programs had higher adoption of good practices, production, and income on average. Farmers receiving aquaculture information from both ICT tools and extension agents achieved the highest harvest and income on average. Results also show that the adoption of the various ICT tools is interrelated, whereas several factors—including age, education, farming experience, share of fish farming in household income, and extension contact—influence the choice of ICT tool. Mobile-based extension was more accessible to youth and more educated farmers, and it could be a good medium for reaching these groups. Television and radio programs are accessible to all types of farmers from different backgrounds; these media are currently underutilized for aquaculture promotion and their application could be enhanced and expanded for current and future projects.

Impact of fish feed formulation training on feed use and farmers’ income: Evidence from Ghana

Impact of fish feed formulation training on feed use and farmers’ income: Evidence from Ghana

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.

Sustainable aquaculture development in sub-Saharan Africa

Aquaculture must grow above the current rate of 11% per year to meet projected demand and reduce dependence on seafood imports. Government support and private investment are urgently needed for sustainable growth.
