DocumentOther documentThe trawl Fisheries of the western Bay of Bengal 2013
Also available in:
No results found.The Western Bay of Bengal (WBoB) trawl fishery is typically a tropical multispecies mixed fishery with a history of commercial exploitation since early 1960s. The nature of fishing changed dramatically with the introduction of trawlers. In the last 50 years, trawlers have become immensely popular and have emerged as the most important fishing craft in the region. The trawl fishery extends from 8oN (off Kanyakumari on the south) to 22oN (off Sunderbans in the north), accessing fishing grounds bet ween 10 m and 150 m depth, but often restricted to a maximum depth of about 70 m. Thus trawling by Indian fishermen has remained exclusively a coastal activity and deep-‐sea trawling is occasional. The main gear is the bottom otter trawl, with two variants, namely the shrimp trawl and fish trawl. The difference between the two variants is that the shrimp trawl scrapes through the bottom with more sinkers, and the fish trawl is hauled slightly off bottom with more floats. The fishery is complex with operation from craft varying in length and efficiency. All trawlers are mechanized, with the engine placed inboard. Being multispecies, the fishery exploits species that widely vary in their life history traits and habitats. Approximately 800 species of elasmobranchs, teleosts, crustaceans, molluscs and echinoderms are taken by the trawls, and at least 300 species contribute to the fishery. -

Also available in:
No results found.Trawl fisheries are an important component of the capture fisheries sector in Malaysia. Although small in terms of percentage of licenses issued (11.79%), their significance is underlined by their contribution to the overall landings (48.19%), as shown in the table below for the year 2011. -
DocumentOther documentA brief introduction to trawl fishery and management issues in Vietnam 2013
Also available in:
No results found.Trawl fisheries play an important role in Vietnam marine capture fishery, not only in terms of total number of fishing effort, but also in catch volume. According to DECAFIREP1 (2013), currently, there are about 19,700 trawlers which were categorized by different fishing fleets based on engine capacity (HP), namely below 20 CV, 20-‐ ˂50CV, 50-‐ ˂90CV, 90-‐ ˂ 150CV, 150-‐ ˂ 250CV, 250-‐ ˂ 400CV and above 400CV. Trawlers occur in all 28 coastal provinces but dominant in the certain provinces, such as the northern cluster: Quang Ninh (1,257 units), Thanh Hoa (1,296 units); the southern cluster including Binh Thuan (1,227 units), Ba Ria – Vung Tau (1,980 units), Ben Tre (2,878 units) and Kien Giang (3,156 units). The small trawlers (bellow 90 CV) normally fish shrimp, prawn while big trawlers focus on fish including small pelagic fishes (anchovy, sardine, scads…) and others. Mainly, shrimp trawlers concentrate in Kien Giang, Ben Tre, Ca Mau and Bac Lieu provinces. Below 90 CV trawlers account for about 46 % total number of trawlers in the country.

Book (stand-alone)High-profileStatus of the World's Soil Resources: Main Report 2015
Also available in:
No results found.The SWSR is a reference document on the status of global soil resources that provides regional assessments of soil change. The information is based on peer-reviewed scientific literature, complemented with expert knowledge and project outputs. It provides a description and a ranking of ten major soil threats that endanger ecosystem functions, goods and services globally and in each region separately. Additionally, it describes direct and indirect pressures on soils and ways and means to combat s oil degradation. The report contains a Synthesis report for policy makers that summarizes its findings, conclusions and recommendations.The full report has been divided into sections and individual chapters for ease of downloading:

BookletCorporate general interestEmissions due to agriculture
Global, regional and country trends 2000–2018
2021Also available in:
No results found.The FAOSTAT emissions database is composed of several data domains covering the categories of the IPCC Agriculture, Forestry and Other Land Use (AFOLU) sector of the national GHG inventory. Energy use in agriculture is additionally included as relevant to emissions from agriculture as an economic production sector under the ISIC A statistical classification, though recognizing that, in terms of IPCC, they are instead part of the Energy sector of the national GHG inventory. FAO emissions estimates are available over the period 1961–2018 for agriculture production processes from crop and livestock activities. Land use emissions and removals are generally available only for the period 1990–2019. This analytical brief focuses on overall trends over the period 2000–2018. -
ProjectProgramme / project reportReview Of Experiences With And Present Knowledge About Fish Aggregating Devices - BOBP/WP/23 1983
Also available in:
No results found.A review of experiences worldwide and of present knowledge about fish aggregating devices (FADs) was carried out by the BOBP during 1981. Nearly 150 institutions and experts were requested to contribute. This paper draws on these replies as also on other published material. The paper describes a spectrum of FADs ranging from very simple and cheap traditional applications for nearshore waters to modern, highly sophisticated and expensive products for off-shore aggregation of tunas and tuna-l ike fishes. Some of the experimental designs described here are worth considering for indicative fishing trials. The preparation of this paper is an activity of the Bay of Bengal Programme for Small-Scale Fisheries Development, referred to in brief as BOBP. The BOBP is funded by the Swedish International Development Authority (SIDA) and the United Nations Development Programme (UNDP) and executed by the Food and Agriculture Organisation of the United Nations. Countries bordering the Ba y of Bengal are members of the Programme. Its main aims are to develop, demonstrate and promote methodologies to improve the conditions of smallscale fisherfolk and to assess and monitor fishery resources.
