This chapter mainly presents the history of shrimp aquaculture in Bangladesh and impacts of shrimp farming on rural livelihoods with particular focus on income and dietary consumption, based on literature reviews and structured field surveys. The chapter also focuses on the complexities of land use patterns and recommends a holistic approach to adopt integrated zoning principles into national policies to sustain shrimp farming in Bangladesh.
Tropical sea cucumber mariculture has potential to become a profitable industry and contribute towards natural population replenishment. Here, we synthesise the fields of progress, current impediments and research opportunities in tropical sea cucumber aquaculture arising from recent studies and an Indo-Pacific symposium. We present novel comparisons of data from hatcheries, earthen ponds and sea pens from published and unpublished studies in various countries. Of the few tropical species to have been cultured, only the sandfish Holothuria scabra has been bred extensively.
This publication is based on materials covered and outputs generated during the Workshop on Risk Assessment Methodologies and Tools for Aquaculture in Sub-Saharan Africa, which was jointly held by WorldFish and FAO in Siavonga, Zambia on 28 June - 2 July 2010. The workshop was delivered as a training exercise to 17 participants from seven sub-Saharan countries and was designed to highlight current methodologies and tools available for environmental risk analysis in aquaculture development.
Two means of reducing feed costs in semi-intensive aquaculture systems in the tropics are considered: economically optimal dietary protein levels and mixing feeding schedules.
Aquaculture is still the fastest-growing food-producing sector and plays an important role in enhancing global food security and alleviating poverty. Tens of millions of people are engaged in aquaculture production, the majority of whom are small-scale farmers who have limited resources and are faced with difficulties due to increasing globalization and the resultant trade liberalization of aquaculture products. Despite these challenges, small-scale farmers remain innovative and continue to contribute to global aquaculture production.
The Brackishwater Aquaculture Development and Training Project, a cooperative effort of the Government of the Philippines, represented by the Bureau of Fisheries and Aquatic Resources (BFAR) under the Ministry of Natural Resources (MNR), the United Nations Development Programme (UNDP), and the Food and Agriculture Organization of the United Nations (FAO), became operational in April 1977. The author was project leader, representing FAO/UNDP until the project was completed in early 1983.
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.
As part of the Philippines' plan to accelerate the country's rate of aquaculture development, a study team was sent to neighboring Southeast Asian countries to observe advances for improving and developing aquaculture in the Philippines. The 3-man team, of which the author was a member, toured Malaysia, Thailand, Japan, and Taiwan. This article is a brief account of observations from the trip and interviews with authorities from selected fisheries agencies, with emphasis on freshwater aquaculture.
Hunger and malnutrition are the world’s most devastating problems and are inextricably linked to poverty. A total of 842 million people in 2011-13, or around one in eight people in the world, were estimated to be suffering from chronic hunger, regularly not getting enough food to conduct an active life (FAO, IFAD and WFP 2013).
Integration of aquaculture with agricul¬ture (integrated farming) provides balanced food production, increases farmers' income, recycles nutrients, protects the environment and optimizes food production where resources are limited. Zimbabwe is a land-locked country with abundant resources in the form of dams, lakes, streams, rivers and groundwater. The rationale for development of integrated farming in Zimbabwe is given.
