Understanding Aquaculture

Understanding Aquaculture PDF Author: Jesse Trushenski
Publisher: 5m Books Ltd
ISBN: 1789180635
Category : Science
Languages : en
Pages : 268

Book Description
Roughly half the seafood we eat comes from farms, and yet many consumers remain hesitant, even resistant to buying farmed fish. Aquaculture is compared with both terrestrial agriculture and capture fisheries and has endured considerable, often unfounded, criticism. Understanding Aquaculture addresses the controversial aspects of aquaculture, answering common questions about the industry and farmed seafood. Are farmed fish safe to eat? Are wild fish more nutritious? Do fish farms pollute the environment? Understanding Aquaculture sets the record straight for the world's most important source of seafood. Aquaculture is critical to food security, both now and in the future, and an informed and supportive public is needed to ensure its potential is fully realized. Informative and engaging, this book is a thoroughly researched resource for students and practitioners, but manages to put the facts within reach of casual readers.

Understanding and measuring the contribution of aquaculture and fisheries to gross domestic product (GDP)

Understanding and measuring the contribution of aquaculture and fisheries to gross domestic product (GDP) PDF Author: Food and Agriculture Organization of the United Nations
Publisher: Food & Agriculture Org.
ISBN: 925131280X
Category : Technology & Engineering
Languages : en
Pages : 83

Book Description
The contribution of aquaculture and fisheries to gross domestic product (GDP) is one of the most widely used indicators of its economic performance. Despite strong interest in and great efforts made towards assessing the contribution of aquaculture and fisheries to GDP, there is a general lack of understanding or consensus on how to properly measure the sector’s contribution to GDP and effectively use the measures for evidence-based policy and planning for sustainable aquaculture and fisheries development. While a fisheries GDP measure has been included in the Sustainable Development Goals (SDGs) of the 2030 Agenda for Sustainable Development (i.e. SDG Indicator 14.7.1: Sustainable fisheries as a percentage of GDP in small island developing states, least developed countries and all countries), it is nevertheless a Tier III indicator for which no internationally established methodology or standards are yet available. This paper contributes to improving the understanding and measurement of aquaculture and fisheries’ contribution to GDP by: (i) using input-output models (including mathematical formulas and numerical examples) to formulate and clarify a set of measures of aquaculture and fisheries’ contribution to GDP; (ii) discussing alternative methods to estimate the measures under data-poor environments; (iii) suggesting an empirical methodology and general guidelines on the estimation and reporting of the measures; and (iv) exploring how to utilize the measures for evidence-based policy and planning. The conceptual framework and empirical methodology suggested in the paper will help move towards internationally established methodology, standards and guidelines on measuring aquaculture and fisheries’ economic contribution.

Publisher: WorldFish
ISBN:
Category :
Languages : en
Pages : 44

Book Description
This study explored how climate-smart agricultural and aquaculture innovations may lead to more successful climate adaptation efforts and enhanced resilience for both men and women in households and across communities, as well as to improved and equitable outcomes in terms of income, nutrition and livelihood opportunities. Specifically, it investigated efforts to target women with household aquaculture innovations to understand (1) if such approaches enable women to use or benefit from them; (2) if and how usage impacts the sustained use of these innovations; and (3) if it would be possible to scale out these innovations to achieve largescale development outcomes.

Genomics in Aquaculture to Better Understand Species Biology and Accelerate Genetic Progress

Genomics in Aquaculture to Better Understand Species Biology and Accelerate Genetic Progress PDF Author: José Manuel Yáñez
Publisher: Frontiers Media SA
ISBN: 2889199576
Category : Genetics
Languages : en
Pages : 153

Book Description
From a global perspective aquaculture is an activity related to food production with large potential for growth. Considering a continuously growing population, the efficiency and sustainability of this activity will be crucial to meet the needs of protein for human consumption in the near future. However, for continuous enhancement of the culture of both fish and shellfish there are still challenges to overcome, mostly related to the biology of the cultured species and their interaction with (increasingly changing) environmental factors. Examples of these challenges include early sexual maturation, feed meal replacement, immune response to infectious diseases and parasites, and temperature and salinity tolerance. Moreover, it is estimated that less than 10% of the total aquaculture production in the world is based on populations genetically improved by means of artificial selection. Thus, there is considerable room for implementing breeding schemes aimed at improving productive traits having significant economic impact. By far the most economically relevant trait is growth rate, which can be efficiently improved by conventional genetic selection (i.e. based on breeding values of selection candidates). However, there are other important traits that cannot be measured directly on selection candidates, such as resistance against infectious and parasitic agents and carcass quality traits (e.g. fillet yield and meat color). However, these traits can be more efficiently improved using molecular tools to assist breeding programs by means of marker-assisted selection, using a few markers explaining a high proportion of the trait variation, or genomic selection, using thousands of markers to estimate genomic breeding values. The development and implementation of new technologies applied to molecular biology and genomics, such as next-generation sequencing methods and high-throughput genotyping platforms, are allowing the rapid increase of availability of genomic resources in aquaculture species. These resources will provide powerful tools to the research community and will aid in the determination of the genetic factors involved in several biological aspects of aquaculture species. In this regard, it is important to establish discussion in terms of which strategies will be more efficient to solve the primary challenges that are affecting aquaculture systems around the world. The main objective of this Research Topic is to provide a forum to communicate recent research and implementation strategies in the use of genomics in aquaculture species with emphasis on (1) a better understanding of fish and shellfish biological processes having considerable impact on aquaculture systems; and (2) the efficient incorporation of molecular information into breeding programs to accelerate genetic progress of economically relevant traits.

Understanding and Applying Risk Analysis in Aquaculture

Understanding and Applying Risk Analysis in Aquaculture PDF Author: James Richard Arthur
Publisher: Food & Agriculture Org
ISBN:
Category : Technology & Engineering
Languages : en
Pages : 113

Book Description
Risk analysis, simply put, is "science-based decision-making." An integrated approach to risk analysis will assist the aquaculture sector in reducing risks to successful operations from both internal and external hazards and can similarly contribute to protect the environment, society and other resource users from adverse and often unpredicted impacts. This leads to improved profitability and sustainability of the sector, while at the same time improving the public's perception of aquaculture as a responsible, sustainable and environmentally-friendly activity. This document presents peer-reviewed technical papers and contributions from international experts.

The State of World Fisheries and Aquaculture 2020

The State of World Fisheries and Aquaculture 2020 PDF Author: FAO
Publisher: Food and Agriculture Organization of the United Nations
ISBN: 9251326924
Category : Technology & Engineering
Languages : en
Pages : 224

Book Description
The 2020 edition of The State of World Fisheries and Aquaculture has a particular focus on sustainability. This reflects a number of specific considerations. First, 2020 marks the twenty-fifth anniversary of the Code of Conduct for Responsible Fisheries (the Code). Second, several Sustainable Development Goal indicators mature in 2020. Third, FAO hosted the International Symposium on Fisheries Sustainability in late 2019, and fourth, 2020 sees the finalization of specific FAO guidelines on sustainable aquaculture growth, and on social sustainability along value chains. While Part 1 retains the format of previous editions, the structure of the rest of the publication has been revised. Part 2 opens with a special section marking the twenty fifth anniversary of the Code. It also focuses on issues coming to the fore, in particular, those related to Sustainable Development Goal 14 and its indicators for which FAO is the “custodian” agency. In addition, Part 2 covers various aspects of fisheries and aquaculture sustainability. The topics discussed range widely, from data and information systems to ocean pollution, product legality, user rights and climate change adaptation. Part 3 now forms the final part of the publication, covering projections and emerging issues such as new technologies and aquaculture biosecurity. It concludes by outlining steps towards a new vision for capture fisheries. The State of World Fisheries and Aquaculture aims to provide objective, reliable and up-to-date information to a wide audience – policymakers, managers, scientists, stakeholders and indeed everyone interested in the fisheries and aquaculture sector.

Welfare of fishes in aquaculture

Welfare of fishes in aquaculture PDF Author: Food and Agriculture Organization
Publisher: Food & Agriculture Org.
ISBN: 9251316910
Category : Technology & Engineering
Languages : en
Pages : 18

Book Description
The welfare of fish in aquaculture is of increasing public concern in Europe and thus of growing importance for fish farmers. Although the topic can be regarded as controversial, due in particular to the lack of available knowledge, there is nevertheless an urgent need for fish farmers, authorities and scientists to develop criteria, approaches and practices to monitor and safeguard the welfare of cultured fish. The objective of this document is to provide the opinion of EIFAAC Member institutions– as the reference body in the field of inland fisheries and aquaculture – on how, given the current state of scientific knowledge, fish welfare issues can be integrated into best practice guidelines for fish culture. This report deals with the welfare of farmed finfish and neither addresses capture fisheries, be they commercial or recreational, nor welfare issues related to the culture of crustaceans and molluscs. The report focuses on the welfare issues of on-growing fish while giving little to no attention to larvae/fry and broodstock. Likewise, the report focuses primarily on the culture conditions for farming of fish and gives little attention to welfare aspects related to transport and slaughter. Finally, emphasis is given to the culture of freshwater fish, but marine species are included where appropriate. It is understood that the principal welfare issues are comparable for freshwater and marine fish culture.

FAO's work on climate change

FAO's work on climate change PDF Author: Food and Agriculture Organization of the United Nations
Publisher: Food & Agriculture Org.
ISBN: 9251339899
Category : Technology & Engineering
Languages : en
Pages : 79

Book Description
The Food and Agriculture Organization of the United Nations (FAO) works towards ending hunger and poverty while using precious natural resources sustainably. The fisheries and aquaculture sector makes substantial contributions to food security, livelihoods and global trade. Global production of fish and other aquatic animals continued to grow and reached 179 million tonnes in 2018, and about 59.5 million people were engaged in the primary sector of capture fisheries and aquaculture. Fishery net exports generate significantly more revenue for developing countries than other agricultural commodities such as rice, coffee and tea. Millions of people are struggling to maintain reasonable livelihoods through the fisheries and aquaculture sector. These are the people who are the most vulnerable to the impacts of climate change. Climate change adds to the many threats and obstacles that already confront them in their day-to-day lives. Particular attention must be given to the most vulnerable if the sector is to continue to contribute to meeting global goals of poverty reduction and food security. This publication presents FAO’s work on climate change and fisheries and aquaculture. It includes examples of FAO’s support to countries so that they are better able to adapt to the impact of climate change in the fisheries and aquaculture sector. It also brings together FAO’s most up-to-date knowledge on climate change, including a portfolio of adaptation tools and measures used to support countries’ climate commitments and action plans.

Agricultural Risk Transfer

Agricultural Risk Transfer PDF Author: Roman Marco Hohl
Publisher: John Wiley & Sons
ISBN: 1119345650
Category : Business & Economics
Languages : en
Pages : 440

Book Description
Gain a holistic view of agricultural (re)insurance and capital market risk transfer Increasing agricultural production and food security remain key challenges for mankind. In order to meet global food demand, the Food and Agriculture Organisation estimates that production has to increase by 50% by 2050 and requires large investments. Agricultural insurance and financial instruments have been an integral part to advancing productivity and are becoming more important in increasingly globalized and specialized agricultural supply chains in the wake of potentially more frequent and severe natural disasters in today’s key producing markets. Underwriting, pricing and transferring agricultural risks is complex and requires a solid understanding of the production system, exposure, perils and the most suitable products, which vastly differ among developed and developing markets. In the last decade, new insurance schemes in emerging agricultural markets have greatly contributed to the large growth of the industry from a premium volume of US$10.1 billion (2006) to US$30.7 billion (2017). This growth is bound to continue as insurance penetration and exposure increase and new schemes are being developed. Agricultural (re)insurance has become a cornerstone of sovereign disaster risk financing frameworks. Agricultural Risk Transfer introduces the main concepts of agricultural (re)insurance and capital market risk transfer that are discussed through industry case studies. It also discusses best industry practices for all main insurance products for crop, livestock, aquaculture and forestry risks including risk assessment, underwriting, pricing, modelling and loss adjustment. Describes agricultural production risks and risk management approaches Covers risk transfer of production and financial risks through insurance and financial instruments Introduces modelling concepts for the main perils and key data sources that support risk transfer through indemnity- and index-based products Describes risk pricing and underwriting approaches for crop, livestock, aquaculture and forestry exposure in developed and developing agricultural systems Become familiar with risk transfer concepts to reinsurance and capital markets Get to know the current market landscape and main risk transfer products for individual producers, agribusinesses and governments through theory and comprehensive industry case studies Through Agricultural Risk Transfer, you’ll gain a holistic view of agricultural (re)insurance and capital market solutions which will support better underwriting, more structured product development and improved risk transfer.
