MeetingMeeting documentA review on oceanic tuna fishery in Sri Lanka and estimation of the length-weight relationships for yellowfin tuna and bigeye tuna 2013
Also available in:
No results found.There are three domint oceanic tu species frequently found in Sri Lankan waters mely yellowfin tu (Thunnus albacares), bigeye tu (Thunnus obesus) and skipjack tu (Katsuwonus pelamis). This paper reviews the trends of oceanic tu landings in Sri Lanka. Also, attempt was made to estimate the length weight relationships of two major species: yellowfin tu (Thunnus albacares) and big eye tu (Thunnus obesus). The annual production of oceanic tu has increased rapidly over the period 1950-2010 and the hi ghest production was reported in 2004. Skipjack tu was the major contributor throughout the period followed by yellowfin tu. Oceanic tu resources are frequently targeted by offshore fishing crafts of three categories: UN3A (9.8 - 12.2 m in length), UN3B (12.2-15.2m) and UN4 (15.2-18.3m). Gillnet has effectively been contributing for catching oceanic tu. The estimated length -weight relationships for yellowfin tu (Thunnus albacares) and bigeye tu (Thunnus obesus) were W= 0.033L2.848 and W=0.011L3 .08 respectively.

DocumentOther documentInternational Year of Forests 2011 – Celebrate forests every day 20112011 is a special year for forests and for all who care about them. To inaugurate it, FAO has created a special issue of Unasylva. More than 100 international days are celebrated throughout the year, in recognition of a vast range of issues, occupations, activities and cultural values important to humanity. What better way to demonstrate the myriad functions of forests than to show that forests have a link to almost all of them? The Unasylva Editor, Andrea Perlis, has compiled a collec tion of images that illustrate these links. With only photos and the briefest of stories, the issue expresses the theme of the international year – “Forests for people” – by showing how forests are important to nearly all kinds of human activity. So when you celebrate Peace Day in 2011 – or International Women’s Day, or Human Rights Day, or World Health Day– even International Civil Aviation Day – you can celebrate forests.

Book (series)Technical reportPesticides residues in food 2010 - Joint FAO/WHO Meeting on Pesticides Residues REPORT 2010
Report of the Joint Meeting of the FAO Panel of Experts on Pesticide Residues in Food and the Environment and the WHO Core Assessment Group on Pesticide Residues Rome, Italy, 21–30 September 2010

No results found.The annual Joint Meeting of the FAO Panel of Experts on Pesticide Residues in Food and the Environment and the WHO Core Assessment Group on Pesticide Residues was held in Rome, Italy, from 21 to 30 September 2010. The FAO Panel of Experts had met in Preparatory Sessions from 16 to 20 September. The Meeting was held in pursuance of recommendations made by previous meetings and accepted by the governing bodies of FAO and WHO that studies should be undertaken jointly by experts to evaluat e possible hazards to humans arising from the occurrence of pesticide residues in foods. During the meeting the FAO Panel of Experts was responsible for reviewing pesticide use patterns (use of good agricultural practices), data on the chemistry and composition of the pesticides and methods of analysis for pesticide residues and for estimating the maximum residue levels that might occur as a result of the use of the pesticides according to good agricultural practices. The WHO Core Asse ssment Group was responsible for reviewing toxicological and related data and for estimating, where possible and appropriate, acceptable daily intakes (ADIs) and acute reference doses (ARfDs) of the pesticides for humans. This report contains information on ADIs, ARfDs, maximum residue levels, and general principles for the evaluation of pesticides. The recommendations of the Joint Meeting, including further research and information, are proposed for use by Member governments of the respective agencies and other interested parties. -
Book (stand-alone)General interest bookHarmonized World Soil Database version 2.0 2023
Also available in:
No results found.The Harmonized World Soil Database version 2.0 (HWSD v2.0) is a unique global soil inventory providing information on the morphological, chemical and physical properties of soils at approximately 1 km resolution. Its main objective is to be useful for modelers and to serve as a basis for prospective studies on agroecological zoning, food security and the impacts of climate change. HWSD v2.0 also serves an educational function, illustrating the geographical distribution of soils as well as their properties globally. HWSD v2.0 is easily accessible and user-friendly.
