This book was released on 1999 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fishing continues to be the most energy-intensive food production method in the world today, and it depends almost completely upon oil fuel-based internal combustion engines. There are as yet no signs of any other energy source that could substitute the internal combustion engine in either the medium or short term. The industry continues to be exposed to global fuel prices and it cannot be assumed that these will remain stable indefinitely. Small-scale fisheries account for nearly half of the world's fish production and, although they are generally more labour-intensive than larger industrial fisheries, they are increasingly affected by energy costs. In developing countries, in spite of the energy conservation initiatives of the 1980s (subsequent to the dramatic rise in the cost of fossil fuels), mechanization continues to increase. Fuel costs have ever more influence not only on consumer prices but also on fishermen's and boat owners' net incomes. When levels of employment and cost-sharing systems are considered, it becomes even more important from a social perspective to improve and maintain energy efficiency within small-scale fisheries. This guide presents information on the key technical areas that affect energy efficiency, but only part of the information presented herein will be applicable to any particular fishing situation. The guide is not a result of new original fieldwork but draws on much of the research and experience of the past two decades, updated where possible to include new technical developments. The guide is divided into two major sections: the first relates to changes in operational techniques rather than changes in technology; the second presents information of relevance to vessel operators who are either considering the construction of a new vessel or overhauling and re-equipping an existing vessel.

This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The recent sharp increase in the price of fuel has had a major impact on the economics of operating fishing vessels. Fishing boat owners and operators struggle to meet this challenge and ask what measures can be taken to reduce the heavy burden of increased fuel cost. Litres of fuel required per tonne of fish landed varies widely depending on the fish specia and fishing method used. Fuel saving methods have to be tailored to each fishing method and fishery. This manual aims to provide practical advice to fishing boat owners and crews, boatbuilders and boat designers and fisheries administrators on ways to reduce fuel costs. It focuses on small fishing boats measuring up to 16 m (50 ft) in length and operating at speeds of less than 10 knots. This covers the majority of the world's fishing boats. It also serves as a guide for those involved with fuel savings for small vessels used in support of aquaculture activities. The manual provides information to boat designers and boat builders on hull shape for low resistance and the selection of efficient propellers. The first chapters of this manual deal with fuel saving measures that can be taken on existing boats without incurring major investment costs. The most effective measures include reducing boat service speed, keeping the hull and propeller free from underwater fouling and maintaining the boat engine. It also suggests that changing fishing methods can save fuel. The final chapters of this manual provide information regarding the fuel savings that are possible by changing from a 2-stroke outboard engine to a diesel engine, installing a diesel engine, and using sail. Selecting economic engine power on the basis of the waterline length and the weight of the boat is discussed. Advice is given on the choice of gear reduction ratio and of propeller related to service speed, service power and propeller rpm. Data are provided to assist with the design of a new fuel-efficient boat and the selection of an optimum propeller. The information contained in this manual is accompanied by many illustrations to make the main points more easily understood. Detailed background information is provided in the appendices. The appendices also contain blank tables that may be used to calculate potential fuel savings, cost of engine operation, the weight of a boat and the diameter and pitch of a propeller."--Publisher's description.

Download or read book Reducing Climate Impact from Fisheries written by Staffan Waldo and published by Nordic Council of Ministers. This book was released on 2014-05-19 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Few doubt the impact from human activities on global warming and the negative consequences of rising temperatures for both terrestrial and marine ecosystems. Efficient policy instruments are needed to change the development. This report uses empirical models to analyse how CO2 emissions, fleet structure, economic performance, and employment opportunities are affected by imposing management instruments to reduce climate impacts. These instruments include both fisheries management such as larger stock levels and more efficient fleets, and energy policy such as fuel taxes or CO2 trading schemes. To get a representative view of the Nordic fisheries, the analysis contains case studies from all the Nordic countries: Sweden, Denmark, Norway, Iceland, Greenland, the Faroe Islands and Finland. The fleet segments analysed range from coastal small-scale trap nets to large off-shore trawlers.

This book was released on 2020-06-01 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: This techno-economic performance review of selected fishing fleets in North and South America presents the findings of four country level studies of fishing fleets in the United States of America, Brazil, Chile and Peru. The review includes financial and economic information of 21 fishing fleet segments, including shrimp and groundfish trawlers, demersal trawlers, longliners, purse seiners, dredgers as well as hook and line fishing vessels. Analysis of the costs and earnings data of these important fishing fleet segments in North and South America, using survey data from 2012 -2017 for the US fleet segments and 2018 data for the South American countries’ fleets showed that 81 percent of the fleet segments had a positive net cash flow. The net profit margins of 38 percent of the 21 fishing fleet segments were >10%. Two-thirds (67%) of the fleet segments presented positive results in terms of their capital productivity as the return on fixed tangible assets (ROFTA) was positive. Twenty four percent of the fleet segments showed return on investment (ROI) figures of twenty percent or more. A majority of the Chilean and Peruvian fleet segments had ROIs of ten percent or higher in 2018. The financial and economic performance of the fishing fleet segments is not only affected by the seafood prices, but also by the fisheries management regime in place, fish species targeted, fish stock status and fishing methods and technologies applied. The age structure of the fishing vessels shows an increasing trend for most of the fishing fleet segments in this review, which adds to the apparent profitability of the vessels in these fleet segments as depreciation and interests on loans are minimized.

This book was released on 2023-11-06 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: To make small-scale fisheries in Thailand more sustainable, fishers need to invest in responsible fishing operations and technologies, reduce overfishing, contribute to fisheries management, and implement climate change adaptation measures. The Southeast Asian Fisheries Development Center and FAO carried out an assessment of the sustainability of currently used fishing technologies and operations in Thailand, to identify options for innovation and improvements. This circular provides information on the current technological status of the Thai fishing fleets, the costs of fishing operations, the management of the main fisheries, and on the status of the main marine fisheries resources targeted by the various fishing fleets. Options for introducing technological innovations for fishing vessels include the reconfiguration of the hull by installing a bulbous bow, stabilizing fins, duct propellors and wave resistance reduction measures. On-board equipment innovations identified include hydraulic hauling systems, power blocks, refrigeration systems, fuel flow monitoring systems, solar panels, and LED lights. To improve safety, vessel owners are recommended to provide lifesaving equipment, radio communications and firefighting equipment, first aid kits, cooking and sanitation facilities, emergency stops on winches and hauling devices, lightning conductors, and distress signal devices. Fishing gear innovations such as circle hooks, low-resistance gears, turtle excluder devices, juvenile and trash excluder devices, and fish aggregating devices are also important innovations for fishing vessel owners to consider.This circular gives fishing vessel owners and financial service providers in Thailand insights in the innovations available, to make better informed fisheries investment decisions.

Download or read book The State of World Fisheries and Aquaculture 2020 written by FAO and published by Food and Agriculture Organization of the United Nations. This book was released on 2020-06-01 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2021-06-11 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: This review of the techno-economic performance of the main global fishing fleets discusses the outcomes from 20 country-level studies of fishing fleets from Africa, Asia, Europe, North and South America. It includes financial, socio-economic and technical information from 103 major (semi-) industrial fishing fleet segments, which are responsible for an estimated 39 percent of marine capture fisheries production worldwide. The analysis of vessel characteristics reveals substantial differences in fishing capacity (in terms of vessel length, tonnage and power) between fleet segments. An increase in the gross tonnage of average vessels was observed in fleet segments also covered in previous reviews. Substantial increases in average length overall and engine power were observed in several Asian fishing fleets. The age structure of the fishing fleets in most regions, except Asia, shows an upward trend. An analysis of the costs and earnings data showed that labour and running costs were the two main cost components for the majority of fleet segments. Ninety-two percent of 97 fleet segments reported a positive net cash flow in the year they were surveyed, in the 2016–2019 period. Net profit margins of 10 percent or more were realized by average fishing vessels in 73 percent of the fleet segments. Returns on investment (ROIs) of 10 percent or higher were realized by 61 percent of the fleet segments. The review also discusses developments in fishing technologies. These developments, along with a general increase in seafood prices, successful fisheries management in some areas, and improved fleet capacity management in Europe and North America, have all contributed to the ongoing, positive financial and economic performance of the main global fishing fleets in recent years.

This book was released on 2020-10-26 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: This techno-economic performance review of selected fishing fleets in Asia presents the findings of six country level studies of fishing fleets in Bangladesh, China, India, Indonesia, Japan and the Republic of Korea. The review includes financial and economic information of 27 major fishing fleet segments, including trawlers, gillnetters, long liners, jiggers, purse seiners, as well as pole and line fishing vessels. An analysis of the costs and earnings data of these important fishing fleet segments in Asia was carried out using national statistics of 2017 for the Japanese and the Korean fleet segments and 2018-19 survey data for the other countries. Eighty-nine percent of the 27 fishing fleet segments reported positive net cash flows. Seventy percent of the fishing fleets realized net profit margins of more than 10 percent. Eighty-one percent of the fishing fleets reported positive results in terms of their capital productivity, as theirs returns on fixed tangible assets (ROFTAs) were positive.The review shows that investments in fishing vessels and fishing operations of these major Asian fishing fleets are generally profitable. Marine capture fishing is a financially viable economic activity in all six major fishing nations included in the review. It generates enough income to cover depreciation costs, interest and loan repayments, and provides sufficient financial resources for reinvestment. Nearly 60 percent of the fishing fleets generated returns on investment (ROIs) of 15 percent and higher, which signals an attractive sector for investments. The total gross value added (GVA) of the 27 fishing fleets to the Asian regional economy was substantial and estimated at around USD 66 billion. The review also reveals a need for adequate management measures, including fleet capacity management plans, to improve the status of fish stock in the region and maintain a healthy and profitable fishing sector.

This book was released on 2020-06-01 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: This techno-economic performance review of selected fishing fleets in Europe presents the findings of European country level studies of fishing fleets of Denmark, France, Germany, Italy, Norway, Spain, Turkey and the United Kingdom of Great Britain and Northern Ireland. The review includes financial and economic information of 42 fishing fleet segments, including demersal trawlers, purse seiners, pelagic trawlers, long-liners, coastal fishing vessels using passive gears, pots and traps fishing vessels and small-scale hand-liners. Analysis of the costs and earnings data of 42 of the main fishing fleet segments in Europe in 2016 showed that all types of vessels had a positive gross cash flow. The average net profit margin of the 41 fishing fleet segments analysed was very good with 20 percent. Eighty-five percent of the fleet segments presented positive return on fixed tangible assets (ROFTAs) of 10 percent and higher. However, 38 percent of the fleet segments demonstrated return on investment (ROI) percentages lower than 10 percent. Comparing the 2016 financial and economic performance results with those of some of the same fleet segments included in the 2002-03 review study, it is clear that general fishing fleet performance in Europe improved. All eight countries together saw a decrease in the number of fishing vessels between 2008 and 2016 of 10 percent, from nearly 60 000 to less than 54 000 vessels. Each of the countries also saw a reduction in total fleet capacity in gross tonnage (GT) and kilowatts (kW). The vessel age structure showed an increasing trend for most of the fishing fleet segments.
