Current Research (2016-2018):

In sub-Saharan Africa, fish is an important source of protein, essential micronutrients, and minerals in the diet of most households. Thus, fish and their sustainable production are major contributors to food security and improved livelihood in Ghana and Tanzania. However, supply of fish is low, causing limited consumption levels. Through five investigations, this project builds on previous AquaFish work to enhance the various facets of aquaculture and its contribution to food supply, nutrition, and health in Ghana and Tanzania. The cost of quality feed frequently limits aquaculture production; hence, researchers continue working to develop cost-effective diets from locally available ingredients (e.g., earthworm, maggot meals) and evaluate the profitability of such feeds in comparison to commercial feeds. To aid fish farmers in determining better methods of feeding, fertilizing, and managing water quality, the project will compare fertilization and feeding strategies and evaluate the physical, chemical, and biological characteristics of ponds during grow-out. To better inform stakeholders along the fish-value chain and more efficiently support markets, researchers will train farmers and fishermen on the use of a cell-phone-based information system and broaden its applicability to include marine fisheries. Through a household survey on dietary diversity and an analysis of household consumption practices, researchers plan to formulate policy measures that improve aquaculture and fisheries practices in order to increase household food security.

Continuing Research:

  • Spat Collection and Nursery Methods for Shellfish Culture by Women (13QSD01PU) – Work Plan
  • Coastal Women’s Shellfish Aquaculture Development Workshop (13BMA01PU) – Work Plan
  • Enhancing the Nutritional Value of Tilapia for Human Health (13SFT02PU) – Work Plan

Research (2013-2015):

This project builds on previous CRSP work to examine the various facets of aquaculture and its contribution to food supply, nutrition, and health in Ghana and Tanzania. Information sharing and trading through a cell phone-based seafood market information system will increase income for tilapia farmers in Ghana. Capacity building efforts to facilitate the participation of women in shellfish aquaculture in Tanzania will be accomplished through a series of trainings and workshops. A value-chain analysis of tilapia and catfish will help to expand aquaculture markets. Results from the various investigations will help to achieve the goals of improving human nutrition, improve efficiency in the value chain, increase incomes for aquaculture producers and traders, diversify production systems, and help reduce postharvest losses through efficient market information sharing mechanisms.
