No results found.The workshop “Fish passage design at cross-river obstacles – experiences from different countries, with potential relevance to Mongolia” was jointly organized by FAO and the Taimen Conservation Fund (TCF) of Mongolia and held in Mongolia in April 2014. Workshop participants included representatives from the Ministry of Nature and Green Development of Mongolia, the Egiin Gol Hydro Power Plant Project Unit (EGHPPPU), the Dorgon hydropower station, the Mongolian Mining Corporation, the National Wat er Association, civil society and the TCF. Workshop participants presented two country reports on the status of fish passage development, research and construction in Mongolia, and on the biology and behaviour of the most important fish species to be considered in planning fish passage facilities in Mongolia, and in particular in the Eg River. The resource persons presented knowledge on different fish passage issues from both the biological and the engineering perspectives. Although the known fa cts are mainly derived from studies in North America and Europe, the basic aspects can serve as “food for thought” also in other regions, including Mongolia. Information provided and designs presented should, however, under no circumstances just be copied but have to be adapted to local conditions (taking into due consideration the species present) while respecting the important basic design criteria which are valid for all passes of the same type at all locations, whether in Europe, North Ameri ca or Asia. As regards the planned Eg River hydropower plant, the workshop did not have a unanimous view concerning the need for, and the usefulness and the environmental impacts of, the planned dam construction. However, all workshop participants unanimously agreed that, should the dam on the Eg River be constructed, a fish passage system would be needed to mitigate the blocked upstream and downstream passage for maintaining genetic exchange between fish in the Eg and Selenge Rivers. The worksh op agreed that trap-andtransport for both upstream and downstream fish passage, with the option of later modifications, would be the only viable solution for this Eg River power plant. However, the resource persons clearly held that based on their assessment during the field visit and the additional information provided during the classroom sessions – from a fish ecological, biodiversity and fisheries point of view – the dam must not be constructed at the planned location because it would inflic t irreversible damage to the aquatic ecosystem. In fact, the excellent ecological status of the Eg River just upstream of the confluence with the Selenge River (and also further upstream in the watershed) calls for the preservation of the given morphological and hydrological characteristics. Alternatives should be sought as regards either the location of the dam (i.e. consider to construct one dam or several smaller dams on one or several other rivers that are less important for taimen) or the t ype of energy produced (solar or wind). Furthermore, the resource persons held that, most importantly, the workshop must not be seen as encouragement to construct new dams solely because the principles of the design and construction of fish passage facilities are known. -
Book (stand-alone)Fish passes. Design, dimensions and monitoring. 2002(Originally published in German by Deutscher Verband für Wasserwirtschaft und Kulturbau e.V.) Many fish species, like salmon and sturgeon, undertake extended migrations as part of their basic behavior, and other fish and invertebrates also undertake short-term or small-scale migrations at certain phases of their life cycles. Activities such as dam construction for water supply and power generation, channelization for navigation and flood control, land drainage and wetland reclamation for agricul tural and urban use all have profound impact on the aquatic ecosystem and thus on natural fish populations. Fish passes are often the only way to make it possible for aquatic fauna to pass obstacles that block their up-river journey. Based on knowledge and experience from mainly Europe and North America, this book describes the various types of fish passes, with special emphasis to "close-to-nature" solutions. It is hoped that this book contributes largely to increase the awareness of the need f or unobstructed fish passage and to multiply the number of well-designed and well-dimensioned fish passes around the globe to restore lost migration routes.

Book (series)Report of the FAO/APFIC/SEAFDEC Regional Workshop on Port State Measures to Combat Illegal, Unreported and Unregulated (IUU) Fishing. Bangkok, Thailand, 31 March–4 April 2008. 2008

No results found.This document contains the report of the FAO/APFIC/SEAFDEC [Food and Agriculture Organization of the United Nations/Asia Pacific Fisheries Commission/Southeast Asian Fisheries Development Center] Regional Workshop on Port State Measures to Combat Illegal, Unreported and Unregulated Fishing, that was held in Bangkok, Thailand, from 31 March to 4 April 2008. The objective of the Workshop was to develop national capacity and promote bilateral, subregional and/or regional coordination so t hat countries would be better placed to strengthen and harmonize port State measures and, as a result, implement further the 2001 FAO International Plan of Action to Prevent, Deter and Eliminate Illegal, Unreported and Unregulated Fishing, the 2005 FAO Model Scheme on Port State Measures to Combat Illegal, Unreported and Unregulated Fishing and contribute to the development of a legally-binding instrument on port State measures. The Workshop addressed: the background and framework fo r port State measures; the FAO Model Scheme including national plans of action to combat IUU fishing and IUU fishing activities in Southeast Asia; the FAO Model Scheme and regional approaches and the 2007 draft Agreement on Port State Measures to Prevent, Deter and Eliminate Illegal, Unreported and Unregulated Fishing; key elements of national laws, and the role of the Asia Pacific Fisheries Commission and the Southeast Asian Fisheries Development Center; national coordination and impl ementation of port State measures; industry perspectives on port State measures, and responses to the questionnaire on port State measures. Working groups were formed to enhance the participatory nature of the Workshop and as a means of engendering broader and deeper discussion on concepts and issues relating to port State measures. A fictitious case study exercise was also undertaken to demonstrate how a port State might deal with a realistic IUU fishing problem. The final session o f the Workshop sought to identify key issues to be addressed on a regional basis as follow-up to the Workshop. Funding and support for the Workshop were provided by the FAO Regular Programme, by the Government of Norway through the Trust Fund for Port State Measures (MTF/GLO/206/MUL) and the FishCode Programme (MTF/GLO/125/MUL [Sweden-SIDA] [SWE/05/IUU Port State Measures/IUU fishing]).
