Available in PDF, EPUB and Kindle. Book excerpt: There are over 1300 species of cyprinids in Asia, and these are utilized by people for food (capture fisheries and aquaculture) and as ornamental species. This publication focuses on cyprinid species that are bred in hatcheries and used in aquaculture and restocking activities. Introduced and threatened species of cyprinids in Asia are also discussed. We are well aware that we have not covered many other cyprinid species that are utilized by people in Asia in various ways: wild species in capture fisheries, self-recruiting species in aquaculture ponds and other water bodies, and aquarist species.
Download or read book Biology and Aquaculture of Tilapia written by José Fernando López-Olmeda and published by CRC Press. This book was released on 2021-11-10 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews up-to-date knowledge on the biology and aquaculture of tilapia, with special focus on the Nile tilapia (Oreochromis niloticus). Tilapia are a group of fish species that have become one of the most cultured worldwide, currently having a big economic impact on both developed and developing countries. The first 12 chapters of the present book cover different aspects of tilapia biology such as genetics, nutrition, osmoregulation, pathology, reproduction and development. Each chapter includes both basic knowledge and its application to tilapia culture. The last 3 chapters are devoted to cutting-edge techniques for the industry of tilapia aquaculture. Experts from both academia and research institutes provide their expertise on the present book.

This book was released on 2020-06-19 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, the aquaculture sector in Ghana has experienced tremendous growth—driven mainly by large-scale cage farms—but it has been unclear how the rural poor have shared in this growth. A research project has been initiated to help diagnose, design, and test interventions for better inclusion of the rural poor, women, and youth in the tilapia value chain. This report describes the baseline data on 603 small-scale tilapia farmers in Ghana. The data collected during two-hour face-to-face interviews during May–July 2019 are disaggregated by socioeconomic indicators, gender, and age group. Baseline data show that 9 percent of farm managers and owners were women, and an additional 9 percent of farms engaged women in some decision-making. Moreover, women contributed 16 percent of family labor and 5 percent of hired labor on farms. Youth represented 14 and 24 percent of owners and managers, respectively, but contributed 68 percent of the total family and hired labor on farms. A large majority of managers and owners had at least high school education, with a third of owners and a quarter of managers attaining at least a college degree. In Brong Ahafo and Ashanti regions especially, most farmers engaged mainly in crop farming and non-farm businesses as their main livelihood, with fish farming as a small contributor to overall household income and livelihood. Farmers in all regions had poor record-keeping and management practices and low compliance with sanitation, fish health, and food safety standards. A wide variety of input usage, management practices, and performance was observed among fish farms. As a result, the profitability of fish farms was also wide-ranging, between –12.00 and 46.00 cedi per m2, with an average of 8.82 cedi per m2. Despite wide variability in production and profits, the majority of farmers experienced positive profits. On average, a farmer received a profit of 2.4 cedi per kilogram of tilapia produced or a 27 percent profit margin. These encouraging figures indicate that farmers who adopt good aquaculture practices can achieve respectable profits.

Download or read book Conservation of Fish and Shellfish Resources written by J. E. Thorpe and published by Elsevier. This book was released on 1995-06-20 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish and shellfish comprise annually nearly 70-million tons of the world's edible animal protein. However, because of this demand, previously vast stocks have often been exhausted to the point of near extinction. The first book of its kind in the area of freshwater/marine biodiversity, this extensive work reviews the present status of genetic resource management, its needs and constraints, various intervening human factors such as pollution and overfishing, and problems posed by different species and life-styles. This discussion of the conservation of fish and shellfish resources is illustrated by four diverse groups: Atlantic salmon, cupped oysters, common and Chinese carp, and Nile tilapia. These results, produced by the collaboration of nine leading population and production geneticists, aquaculturists, and behavioral and developmental ecologists should become a fundamental resource useful to biologists, scientists and advisors exploring current issues in the fishery sciences. - Four page color plate section - Database of key organizations for contact purposes - Foreword by Dr. Mike Strauss, Am. Assoc. for the Advancement of Science; and Dr. Peter Day, Rutgers University - Four in-depth case studies by international experts - Editors are major names in marine/freshwater fisheries science - Originally sponsored and reviewed by U.S. National Academy of Sciences

This book was released on 2019-07-24 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conservation, sustainable use and development of aquatic genetic resources (AqGR) is critical to the future supply of fish. The State of the World’s Aquatic Genetic Resources for Food and Agriculture is the first ever global assessment of these resources, with the scope of this first Report being limited to cultured AqGR and their wild relatives, within national jurisdiction. The Report draws on 92 reports from FAO member countries and five specially commissioned thematic background studies. The reporting countries are responsible for 96 percent of global aquaculture production. The Report sets the context with a review of the state of world’s aquaculture and fisheries and includes overviews of the uses and exchanges of AqGR, the drivers and trends impacting AqGR and the extent of ex situ and in situ conservation efforts. The Report also investigates the roles of stakeholders in AqGR and the levels of activity in research, education, training and extension, and reviews national policies and the levels of regional and international cooperation on AqGR. Finally, needs and challenges are assessed in the context of the findings from the data collected from the countries. The Report represents a snapshot of the present status of AqGR and forms a valuable technical reference document, particularly where it presents standardized key terminology and concepts.
