Book Description
The environmental impact assessments on the use of the two feed types suggested that good feed management and overall farming practices, and improving the quality of trash fish/low-value fish or pellets reduce the impacts of feed on the water beneath and around the culture sites. In addition, a good culture site where the carrying capacity is not stressed by aquaculture and non-aquaculture activities will considerably reduce the mortality risks from biotic and abiotic hazards. The technical and economic findings of the study were noted by the farmers, and contributed to the changes in their attitudes towards the pellet feeds from negative or neutral to positive. The recommendations of the project included providing the opportunities and enabling the farmers to translate their positive attitude into actual and sustained adoption of pellet feeds.

Book Description
The Asia-Pacific region is remarkably diverse and wide ranging, geographically, in its flora and fauna, culturally, institutionally and economically. The region includes the two most populous countries in the world, China and India, a greater part of the Asian continent, the Australian continent, and many small islands, mostly in the Pacific Ocean, which are some of the smallest island nations in the world. Fisheries and aquaculture are socio-economically important sectors to most nations in the Asia-Pacific region and most nations in the region have high rates of fish consumption, mostly sourced from aquaculture although the small island nations depend to a greater extent on capture fisheries. This review entails analyses of the aquaculture sector in Asia-Pacific including the status and trends, progress made in achieving sustainable development, salient challenges, issues and anticipated future development. Status and trends are based on data extracted from the FAO Fishery and Aquaculture Statistics (FAO, 2020a; FAO, 2020b), unless stated otherwise, and are mostly for the period from 2008 to 2018 and occasionally for the period from 1990 to 2018 for relevant historical comparison and longer-term contextual analyses.

Book Description
Groupers are fascinating charismatic fishes commonly found in reef habitats around the world that sustain a global multimillionaire fishery. They are an important top predator species and therefore of paramount ecological importance for reef systems' resilience. The book, Biology and Ecology of Groupers is an up-to-date review of the main bio-ecological topics involving worldwide groupers species oriented to the academic community and managers. It covers aspects of classification and phylogenetic relationships, geographical distribution, and life history related characteristics (Section I), including the major threats of groupers populations, case studies of successful management and comments about the future of groupers in our changing world (Section II).

Book Description
This book is the proceedings of a meeting held in Bangkok in December 1992 on the use of farm-made feeds in Asia. It contains eleven country reviews of the topic, for Bangladesh, Cambodia, China, India, Indonesia, Malaysia, Nepal, the Philippines, Singapore, Thailand and Vietnam. Nine technical papers are also included. Three are on-farm feed preparation and feeding strategies - for carps and tilapias, for catfish and snakehead, and for marine shrimp and prawns. Five other working papers are on economics, the selection of equipment, feed ingredients, formulation and on-farm management, and supplementary feeding in semi-intensive aquaculture, all directed at farm-made, rather than commercial feeds. The ninth working paper is a regional overview of aquafeeds in Asia. An analysis of the material in the eleven country papers is also presented.

Book Description
The rise into global prominence and rapid growth of finfish and crustacean aquaculture has been due, in part, to the availability and on-farm provision of feed inputs within the major producing countries. More than 46 percent of the total global aquaculture production in 2008 was dependent upon the supply of external feed inputs. For the aquaculture sector to maintain its current average growth rate of 8 to 10 percent per year to 2025, the supply of nutrient and feed inputs will have to grow at a similar rate. This had been readily attainable when the industry was young. It may not be the case anymore as the sector has grown into a major consumer of and competitor for feed resources. This paper reviews the dietary feeding practices employed for the production of the major cultured fed species, the total global production and market availability of the major feed ingredient sources used and the major constraints to feed ingredient usage, and recommends approaches to feed ingredient selection and usage for the major species of cultivated fish and crustacean. Emphasis is placed on the need for major producing countries to maximize the use of locally available feed-grade ingredient sources, and, in particular, to select and use those nutritionally sound and safe feed ingredient sources whose production and growth can keep pace with the 8 to 10 percent annual average annual growth of the fed finfish and crustacean aquaculture sector.

Book Description
This technical paper provides a comprehensive review of on-farm feeding and feed management practices in aquaculture. Based on the information presented in the eleven case studies, ten specialist reviews and from other relevant publications, an overview paper presents concluding remarks and recommendations on some of the major issues and constraints in optimizing feed production, use and management.

Book Description
Fish have been a major component of our diet and it has been suggested that fish/seafood consumption contributed to the development of the human brain, and this together with the acquisition of bipedalism, perhaps made us what we are. In the modern context global fish consumption is increasing. However, unlike our other staples, until a few years back the greater proportion of our fish supplies were of a hunted origin. This scenario is changing and a greater proportion of fish we consume now is of farmed origin. Aquaculture, the farming of waters, is thought to have originated in China, many millennia ago. Nevertheless, it transformed into a major food sector only since the second half of the last century, and continues to forge ahead, primarily in the developing world. China leads the global aquaculture production in volume, in the number of species that are farmed, and have contributed immensely to transforming the practices from an art to a science. This book attempts to capture some of the key elements and practices that have contributed to the success of Chinese aquaculture. The book entails contributions from over 100 leading experts in China, and provides insights into some aquaculture practices that are little known to the rest of the world. This book will be essential reading for aquaculturists, practitioners, researchers and students, and planners and developers.

Book Description
After agreeing on the methodology and outline of the country reports, the authors of the case studies, for each feeding strategy and farming system, analyzed demographic factors (including age and marital status, education and ownership structure), physical characteristics (average number of ponds and average pond size), and other input features (stocking strategies, feeding practices, types of feed, frequency and intensity of feeding and labour utilization). The case studies also identified the principal input costs, assessed the economic rates of return (gross and net margins), returns to labour, land and capital, gross and net total factor productivity, break-even prices and production and returns on capital for each feeding strategy. Problem areas were identified for the different farming systems.

Book Description
This edition of The State of World Fisheries and Aquaculture highlights the vital role of fisheries and aquaculture in both food and nutrition security as well as economic expansion. The sector remains a major supplier of high-quality animal protein and supports the livelihoods and well-being of more than ten percent of the world's population. International trade in fish has reached new peaks as overall production has continued to rise. Yet, as the document underlines, an array of problems - ranging from the need for more effective governance to that of ensuring environmental sustainability - threatens to undermine the sector's valuable contribution to alleviating hunger and reducing poverty. Using the latest available statistics on fisheries and aquaculture, this edition presents a global analysis of the sector's status and trends.
