Experts Workshop on Fishway Design Principles to Enhance Sustainability of Inland Fishery in the Southeast Asian Region
Activity 20 Maret 2016


SEAFDEC IFRDMD dispatched two researchers (Dr. Dina Muthmainnah and Ms. Sevi Sawestri) to participate on Experts Workshop on Fishway Design Principles to Enhance Sustainability of Inland Fishery in the Southeast Asian Region. The Workshop has objective to obtain information from experts on works related to biology and ecology related to fish migration and fishways, as well as their recommendations for undertaking of activities under the ACIAR-supported project on “Application of fish passage design principles to enhance sustainability of inland fishery resources in the Southeast Asian region”, particularly on criteria for fishway design towards enhancing the sustainability of inland fishery resources in the Southeast Asian region.

The Workshop organized on 6-10 March 2016, by arranging an excursion program and workshop. Excursion program was arranged for participants to visit fish passage at Sui Reservoir in Cham Phone District; and fish friendly floodgates in Huay Papak, Huay Kae and Huay Phin in Xayburi District, Savanakhet Province in Lao PDR on 6 March 2016. Participants also observed fishway facilities at Thoranit-naruemit Watergate, and Na Koo Watergate in Nakhon Phanom Province; and Suraswadi Watergate in Sakon Nakhon Province in Thailand on 7 March 2016. Theworkshop session held on 8-10 March 2016 in Sakon Nakhon Province, Thailand. The Workshop attended by regional and international experts on relevant subject (e.g. fish biology, ecology, fishway designs), relevant officers and experts of the Department of Fisheries and the Royal Irrigation Department of Thailand, SEAFDEC Secretary-General, concerned officers of the SEAFDEC Secretariat, TD, and IFRDMD.

As we know that inland ecosystems and fisheries are considered as very important for Indonesia, and there are several stakeholders involved in the utilization of inland water resources. In our country, all activities that are likely to cause impacts on the environment, and there is no regulation concerning the construction of fish passage facilities. There are various management authorities (e.g. for the aspects of irrigation, hydropower, fisheries, tourism, sports, etc.) involved in the construction/operation of cross river obstacles. The decline of several fish species, as well as impacts on water quality and flows, were observed after the construction of several cross-river obstacles. However, most of the constructions do not have a fish passage facility as such facilities were constructed only when strongly required or upon pressure by the community or other bodies e.g. for Perjaya Dam in Ogan Komering Ulu District, South Sumatra Province, Batang Hari Dam in West Sumatra Province, Wawatobi Dam in South Sulawesi and Sulewana Dam in Centre Sulawesi). The problems concerning the construction of fish passage facilities include the lack of awareness and knowledge of the appropriate design of fish passage facilities.

The workshop was noted that clear standard/criteria for design of fishways (both for upstream and downstream migration) is necessary to facilitate communication with decision makers to understand specific criteria/requirements for fishways. Information on benefit of fishway to biodiversity and contribution to nutritional requirement of people should also be included. (#dina mth).
