Title:  Enhancing Aquaculture Production Efficiency, Sustainability, and Adaptive Measures To Climate Change Impacts In Bangladesh

Theme: Environmental Management for Sustainable Aquatic Resources Use

Lead US University: North Carolina State University

Host Country & Partner Institutions:
Bangladesh: Bangladesh Agricultural University, Khulna University, Patuakhali Science and Technology University, Shushilan NGO

Current Research (2016-2018):

Bangladesh, one of the most densely populated countries in the world, has high rates of poverty and widespread malnourishment, particularly among women and children. Sustainable aquaculture in Bangladesh is one solution for increasing food security, enhancing dietary nutrition, and improving the economic livelihoods for its poorest citizens. However, technical, environmental, and economic barriers limit aquaculture production in the country. This project, through five investigations, seeks to address such barriers by developing technologies for enhancing aquaculture production efficiency, intensification, and sustainability to improve household income and nutrition, particularly for low-income farming households. With the hope of increasing feed efficiency and reducing associated costs, researchers will evaluate the effectiveness of nutritional conditioning and characterize the respective changes in gut microbial communities and nutrient absorption in tilapia. To address environmental and economic concerns for the existing farming industries of shrimp and prawn, researchers will continue to assess the potential for farming Pangasius catfish in brackish (hyposaline) waters in regions traditionally reliant solely upon shrimp farming.  Researchers will also examine a novel polyculture/land-farming strategy, culturing Mola (Amblypharyngodon mola) with prawns and using pond muds as fertilizer to grow fresh vegetables on unflooded gher-dykes. Lastly, researchers will evaluate the effects of reducing feed and investigate polyculture technology, particularly in indigenous, air-breathing fishes such as Shing and Koi (nutrient rich and hardy fish), to enhance incomes and dietary nutrition, while reducing environmental impacts. To maximize the adoption and impact of improved technologies, researchers will hold a series of workshops and trainings, complemented by the distribution of outreach materials.

Research (2013-2015):

Bangladesh is one of the most densely populated countries in the world, with high rates of poverty and widespread malnourishment, particularly among women and children. Aquaculture in Bangladesh is considered a high food security priority for enhancing dietary nutrition and improving the economic livelihoods for its poorest citizens. However, technical, environmental, and economic barriers limit aquaculture production in Bangladesh. This project seeks to develop technologies for enhancing aquaculture production efficiency, intensification, and sustainability to improve household income and nutrition. One component of the project will incorporate reduced-feeding protocols and polyculture technology to improve production culture efficiencies, particularly in indigenous, air-breathing fishes such as Shing and Koi (nutrient rich and hardy fish). Research on feed conversion of tilapia will be conducted to lay the groundwork for the development of probiotic supplements for improving fish growth. To address environmental and economic concerns for the existing shrimp farming industry, research will examine “Best Management Practices” as well as assess the potential for farming Pangasius catfish in brackish (hyposaline) waters in regions traditionally reliant solely upon shrimp farming. A novel polyculture/land-farming strategy will be tested, culturing Mola (Amblypharyngodon mola) with prawns using pond muds as fertilizer to grow fresh vegetables on unflooded gher-dykes.

With a focus on women-led households in coastal Bangladesh, particularly those reliant on the sale of mudcrab (Scylla serrata) as a sole source of income, a value-chain analysis on mud-crab farming will be conducted to identify how this industry can be further developed for their benefit.
