The use of alien species is a proven means to increase production and value from aquatic ecosystems. In the Mekong/Lanchang basin, alien species such as tilapia (Orechromis spp.) play an important role in providing cheap and readily available protein to rural and poor sectors. However, alien species are now recognized as one of the most significant threats to aquatic biodiversity. Several steps are necessary for effective use and control of alien species, but one of the most important was identified to be following codes of practice similar to that developed by the International Council for the Exploration of the Sea.

The Expert Consultation on the Development of the Sustainable Aquaculture Guidelines was held in Rome, Italy from 17 to 20 June 2019 to come out with a proposal for developing the Sustainable Aquaculture Guidelines to be presented in August 2019 at the tenth session of the Sub-Committee on Aquaculture of the Committee on Fisheries (COFI). The specific objectives of this Expert Consultation were to propose criteria for selecting case studies aimed at providing lessons learned for the development of the Sustainable Aquaculture Guidelines, and methodologies for documenting the case studies, for analysing the case studies to identify the lessons learned, and for developing the Sustainable Aquaculture Guidelines by also making use of existing guidelines. The consultation was attended by 15 experts, one resource person and FAO staff. The consultation was organized into both plenary and group discussions. The Experts agreed on a proposed methodology for identifying and selecting the lessons learned from strategies and experiences of aquaculture development worldwide; a methodology for documenting and analysing the lessons learned; a list of thematic modules; a gap analysis between existing guidelines and needs for new ones, and; an updated roadmap for the development of the Sustainable Aquaculture Guidelines.

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.

Tilapia Culture, Second Edition, covers the vital issues of farmed tilapia in the world, including their biology, environmental requirements, semi-intensive culture, intensive culture systems, nutrition and feeding, reproduction, seed production and larval rearing, stress and disease, harvesting, economics, trade, marketing, the role of tilapia culture in rural development and poverty eradication, and technological innovations in, and the environmental impacts of, tilapia culture. In addition, the book highlights and presents the experiences of leading countries in tilapia culture, thus making it ideal for tilapia farmers and researchers who seek the most relevant research and information. The new second edition not only brings the most updated information within each chapter, but also delivers new content on tilapia transfers, introductions and their impacts, the use of probiotics and other additives in tilapia culture, tilapia trade, including marketing, and sustainability approaches and practices, such as management practices, ecosystem approaches to tilapia culture, and value chain analyses of tilapia farming. - Presents the biology of tilapia, including taxonomy, body shapes, geographical distribution, introductions and transfers, gut morphology, and feeding habits - Covers semi-intensive tilapia culture in earthen ponds, tanks, raceways, cages, recirculating systems, and aquaponics - Provides the latest information on brood stock management, production of monosex tilapia, seed production, and larval rearing under different culture systems - Highlights the most common infectious and non-infectious diseases affecting farmed tilapia, with a full description of disease symptoms and treatment measures - Provides an in-depth exploration of tilapia economics, trade and marketing

Coastal deltas represent one of the most diverse biophysical regions in the tropical developing world. These regions are also home to large human populations and are significant areas of agricultural production and industrialization. Tropical deltas currently face a number of environmental pressures stemming from their intensive use and rapid development, and new threts are emerging as a result of global climate change and expected sea-level rise. Focusing on the developing countries of Asia, Africa and South America, chapters explore the impact of development strategies and existing land and water management practices on delta environments. New management techniques are also explored, which address conflicts between rice-based agriculture, aquaculture, fisheries, and the emerging threat of climate change. Illustrating the current key management challenges involved in protecting tropical deltaic systems in the face of environmental change, this book will be an essential reference for students, researchers and policy makers in agriculture, environmental science and aquaculture.

The Working Group on Aquaculture (WGA reviewed the decisions and recommendations of the third session of the Commission held in Doha, Qatar from 9 to 11 May 2005, and the activities of the WGA that followed. Among the activities, the experts acknowledged that progress had been made with regards to the technical arrangements that would lead to the preparation of the RECOFI Regional Aquaculture Information System (RAIS). The WGA acknowledged that the legal and policy framework project proposal remained a major regional priority and agreed to actively seek funding support from the Commission Members as well as to approach regional donor agencies through the coordination of the RECOFI Secretariat.--Publisher's description.

Due to the increasing pressure of a globalized economy and under the effects of a changing climate, biological invasions have become a frequent feature of marine and freshwater environments. Global fisheries and aquaculture are therefore required to adjust to these changes, with the dual aim of reducing the negative ecological consequences caused by these species and making the most of the advantages they might bring. Here, capitalizing on a wide spectrum of management actions which can be implemented to control and/or adapt to aquatic invasions, nine measures are presented; they can be grouped under environmental, social or socioeconomic strategies, exploring their potential, main challenges and enabling factors. The nine measures, provided with key recommendations, are: #1: Develop and manage a commercial fishery #2: Promote recreational harvesting #3: Explore market opportunities #4: Implement outreach programmes #5: Foster stakeholder engagement #6: Implement spatial control #7: Implement biological control #8: Restore ecosystems #9: Do nothing These suggestions, discussed among a group of international experts and presented in a synthetic form, may be used as a practical resource (though not an exhaustive one), to aid in the evaluation and identification of appropriate fisheries management responses to aquatic invasive species in the context of climate change. While it may not address all the complexities of the subject, it provides a starting point for adaptation strategies, recognizing the diverse legal, cultural and socioeconomic conditions in different fishery contexts, offering valuable insights for policymakers, fisheries managers, and practitioners who have to deal with aquatic invasions.
