Aquaculture technologies in Bangladesh: An assessment of technical and economic performance and producer behavior


Book Description

This study evaluates the performance of a wide range of aquaculture systems in Bangladesh. It is by far the largest of its kind attempted to date. The purpose of this study was to identify and analyze the most important production systems, rather than to provide a nationally representative overview of the entire aquaculture sector of Bangladesh. As such, the study yields a huge amount of new information on production technologies that have never been thoroughly researched before. The study reveals an extremely diverse array of specialized, dynamic and rapidly evolving production technologies, adapted to a variety of market niches and local environmental conditions. This is a testament to the innovativeness of farmers and other value chain actors who have been the principal drivers of this development in Bangladesh. Data was collected from six geographical hubs. The survey was conducted from November 2011 to June 2012. Technological performance in terms of detailed input and output information, fish management practices, credit and marketing, and social and environmental issues were captured by the survey questionnaire, which had both open and closed format questions. The study generated insights that enable better understanding of aquaculture development in Bangladesh.




Securing food for all in Bangladesh


Book Description

Securing Food for All in Bangladesh presents an array of research that collectively address four broad issues: (1) agricultural technology adoption; (2) input use and agricultural productivity; (3) food security and output market; and (4) poverty, food security, and women’s empowerment. The fifteen chapters of the book address diverse aspects within these four themes. Access to sufficient food by all people at all times to meet their dietary needs is a matter of critical importance. Despite declining arable agricultural land, Bangladesh has made commendable progress in boosting domestic food production. The growth in overall food production has been keeping ahead of population growth, resulting in higher per capita availability of food over time. In the early 1970s, Bangladesh was a food-deficit country with a population of about 75 million. Today, the population is 165 million, and the country is now self-sufficient in rice production, which has tripled over the past three decades. Along with enhanced food production, increased income has improved people’s access to food. Furthermore, nutritional outcomes have improved significantly. Nevertheless, the challenges to food and nutrition security remain formidable. Future agricultural growth and food and nutrition security are threatened by population growth, worsening soil fertility, diminishing access to land and other scarce natural resources, increasing vulnerability of crop varieties to pests and diseases, and persistent poverty leading to poor access to food. In addition, the impacts of climate change—an increase in the incidence of natural disasters, sea intrusion, and salinity—will exacerbate food and nutrition insecurity in the coming decades if corrective measures are not taken. Aligned with this context, the authors of the book explore policy options and strategies for developing agriculture and improving food security in Bangladesh. Securing Food for All in Bangladesh, with its breadth and scope, will be an invaluable resource for policymakers, researchers, and students dedicated to improving people’s livelihoods in Bangladesh.




The Sundarbans: A Disaster-Prone Eco-Region


Book Description

This book explores the Sundarbans eco-region from a trans-boundary perspective, examining the cross-country interaction that helps planners to develop more efficient coastal zone planning for the delta. The dynamic ecosystem of the Sundarbans is considered the largest coastal delta in the world. It is located in the Bay of Bengal and spans across Bangladesh and West Bengal (India). Featuring chapters by experts from a range of fields, it addresses (i) risk factor analyses, and the geohydrological, climatic, natural, socio-economic, and anthropological factors related to the Sundarbans; (ii) strategies for sustainability in natural resource management in trans-boundary Sundarbans, cutting across political boundaries; (iii) improved agriculture, fisheries, and forestry practices and their impacts on the socio-economy for livelihood security; and (iv) a future road map for improvements. This book will be of value to those working in academia, as well as to experts and professionals in coastal zone planning and management.




The making of a blue revolution in Bangladesh: Enablers, impacts, and the path ahead for aquaculture


Book Description

A rapid increase in aquaculture production in Bangladesh has lowered fish prices, increased protein consumption, and reduced poverty. The Making of a Blue Revolution in Bangladesh offers a valuable case study of how this transformation in the fish value chain has occurred and how it has improved the lives of both fish producers and fish consumers and considers the future potential of aquaculture in Bangladesh.




Women and men in small-scale fisheries and aquaculture in Asia


Book Description

Fisheries and aquaculture contribute to food security and livelihoods of millions of people in Asia. Both women and men are engaged in fisheries and aquaculture. In the past ten years, many actors have worked on raising awareness on women’s contribution as well as promoting gender equality in fisheries and aquaculture. This study aims to consolidate the efforts to date to provide recommendations for action and future studies. Its objective is to answer the following questions for small-scale fisheries and aquaculture in Asia: (i) What is the division of labour between women and men in specific fisheries and aquaculture practices and what are the differences with respect to their access to assets, resources and entitlements? (ii) What are the drivers of such differences? (iii) What could be critical entry points and opportunities for addressing inequalities and discriminatory practices? To answer these questions, the study conducted an online literature search on gender and fisheries and aquaculture in Asia, selecting articles published between 2011 and 2021. This period was selected to understand the contemporary condition and state of knowledge, and since we aimed for an exhaustive list of literature, some limits in the time period was necessary. The review included both published peerreviewed papers in journals as well as other research and project reports that are available online. In total, it reviewed 253 publications on fisheries and 210 publications on aquaculture. The top four countries where studies were conducted are India (44.3 percent of fisheries and 24.3 percent of aquaculture articles), the Philippines (35.6 percent of fisheries and 17.6 percent of aquaculture articles), Bangladesh (27.7 percent of fisheries and 32.9 percent of aquaculture articles) and Indonesia (30.8 percent of fisheries and 20.5 percent of aquaculture articles). The findings based on each research question are presented in this publication.

Book Description

Key features: Takes a quantitative approach to the science of aquaculture Covers the complete landscape of the scientific basis of fish culture Promotes problem solving and critical thinking Includes sample problems at the end of most chapters Guides the reader through the technical considerations of intensive aquaculture, including fish growth rates, hydraulic characteristics of fish rearing units, oxygen consumption rates in relation to oxygen solubility and fish tolerance of hypoxia, and water reconditioning by reaeration and ammonia filtration. Discusses the environmental effects of aquaculture Includes a chapter on hatchery effluent control to meet receiving water discharge criteria Aquaculture Technology: Flowing Water and Static Water Fish Culture is the first book to provide the skills to raise fish in both a flowing water and a static water aquaculture system with a pragmatic and quantitative approach. Following in the tradition of the author’s highly praised book, Flowing Water Fish Culture, this work will stand out as one that makes the reader understand the theory of each type of aquaculture system; it will teach the user "how to think" rather than "what to think" about these systems. The book presents the scientific basis for the controlled husbandry of fish, whether it be in a stream of water or a standing water pool. Part 1, Flowing Water Fish Culture, is a major revision of the author’s initial book and includes greatly expanded coverage of rearing unit design criteria, fish growth and the use of liquid oxygen, hatchery effluent control, and recirculating systems. Part 2, Static Water Fish Culture, presents the scientific basis of fish culture in standing water systems including nutrient and dissolved gas dynamics, pond ecology, effects of fertilization and supplemental feeding, water quality management and representative static water aquacultures. Aquaculture Technology conveys the science in a manner appropriate for use by university students and teachers and others involved in fish production and aquaculture research and development worldwide. It will enable the reader to adapt to changing technologies, markets, and environmental regulations as they occur.
