Progress and the future for tilapia farming and seed production in Bangladesh

Tilapia farming has great potential in Bangladesh. Tilapia promises to become a primary cultured species for freshwater and brackish water ecosystems, and therefore may also be a major source of employment. Bangladesh could become one of the leading Asian countries for tilapia seed production and grow-out farming. This article looks at the current status of Tilapia farming and seed production in Bangladesh.

Market potential and challenges for expanding the production of sea cucumber in South-East Asia

The marketing system for sea cucumber in South-East Asia is generally inefficient, and marketing channels are multilayered. Information asymmetry encourages proliferation of redundant players in the distribution system, while high transaction costs keep the overall marketing margin high but the price received by collectors low. This paper is limited to establishing the major features of the marketing system for sea cucumber in South-East Asia.

Impact of tannery effluents on the aquatic environment of the Buriganga River in Dhaka, Bangladesh

This study presents an overview of the existence and effects of six heavy metals, chromium (Cr), lead (Pb), cadmium (Cd), mercury (Hg), manganese (Mn), and aluminum (Al), in tannery effluents released to the Buriganga River in Dhaka, Bangladesh. The pollutants were found in three different sources, such as effluents from tanneries, contaminated river water and three species of fish: climbing perch (Anabas testudineus), spotted snakehead (Channa punctata), and Black tilapia (Oreochromis mossambicus) caught from the river.

Vertical agriculture: Homestead horticulture suspended in sacks

Suspending horticulture in sacks above the ground can result in higher levels of productivity for vegetables when the challenges of unfertile or saline soil, flooding, waterlogging, and land and water constraints are regularly encountered. Previously used feed and fertilizer sacks are filled with a high-productivity soil mixture. Vegetables are grown on the top and/or in holes cut into the sides of the sacks. While growing vegetables in sacks has existed for many years in Bangladesh, the technique has been modified by WorldFish in collaboration with farmer researchers.

Overview of sea cucumber aquaculture and sea-ranching research in the South-East Asian region

South-East Asia has traditionally been the global centre of production of tropical sea cucumbers for Chinese markets. Early research into culture methods took place outside this region, notably in India, the Pacific region and China. However, recent investment in Holothuria scabra (sandfish) culture has led to some significant advances within this region. The Philippines and Vietnam have been at the forefront of recent efforts, with involvement from substantial national programs and local institutions as well as international donors and scientific organisations.

Integrated floating cage aquageoponics system (IFCAS): An innovation in fish and vegetable production for shaded ponds in Bangladesh

Farmer participatory action research was carried out from July to December 2013 to design and construct a technology known as IFCAS (integrated floating cage aquageoponics system) for growing fish and vegetables in shaded ponds in the Barisal region of Bangladesh under the EU funded ANEP (Agriculture and Nutrition Extension Project). This article attempts to assess how this integrated technology fits into the socio-economic conditions of farming households and physical characteristics of the pond.

Governance structures and sustainability in Indian Ocean sea cucumber fisheries

Good governance is paramount to the sustainability of fisheries, and inclusiveness of stakeholder groups has become the centerpiece in the ethos of managing small-scale fisheries. Understanding the effect of governance network structures on fishery sustainability can help guide governance to achieve desired outcomes. In the present study, the fishery context and governance structure of sea cucumber fisheries in the Indian Ocean were evaluated.

Climate-smart house: Housing that is cyclone resistant and food, energy and water efficient in Bangladesh

Since cyclones Sidr (2007) and Aila (2009), communities in southern Bangladesh have increasingly needed to protect their homes and livelihoods from destructive natural disasters. WorldFish embarked on a climate-resilient housing project in 2013, building a prototype climate-smart house that is resilient to cyclones and is also water, food, energy and space efficient. This brief describes how the climate-smart house provides protection against cyclones and flooding and supports efficient use of water and energy.

Cereal Systems Initiative for South Asia in Bangladesh (CSISA-BD) : Women farmers training case study update

The USAID-funded Cereal Systems Initiative for South Asia in Bangladesh (CSISA-BD) project is a five-year initiative implemented through a collaboration between three CGIAR member centers, the International Rice Research Institute (IRRI), International Maize and Wheat Improvement Center (CIMMYT) and WorldFish. The project aims to increase household income, food security and livelihoods in impoverished and agriculturally-dependent regions of Bangladesh.

Aquaculture technology exchange between Bangladesh and Nepal in the Agriculture and Nutrition Extension Project

Technology and knowledge transfer has been a great challenge for many developing countries in South Asia due to poor information and communications technology networks. A limited number of institutions focused on science and technology, weak linkages among private and public institutions and political instability. These factors have hampered the successful transfer and diffusion of new and proven technologies between countries.
