Juvenile Fish Passage Guidance at Hydro Stations and Improved Fish Passage trough Culverts and other Conveyances

WA21-Webinar

Juvenile anadromous salmonids often need to transit hydro stations during their oceanward migration. Injuries and even death are a result of extreme pressure differential and runner strikes.  The options to avoid passing through turbines at many stations is limited. We have developed a Behavioral Fish Guidance System that can be used to direct juvenile fish to a safe bypass such as a spillway. We have also developed a novel weir structure that can be installed in a road culvert, tunnel or other conveyance to improve passage for a variety of species and life histories. The Flexi Baffle can be modified for a wide variety of installations. The baffles are designed to have minimal effect on the capacity of structures but increase the range at which fish and other aquatic organisms can pass a structure.

Shane Scott from SSA Environmental LLC in Vancouver, Washington, USA, will share his experience working for over 20 years on the largest fish passage mitigation program in the world at the Federal Columbia River Power System. He will also talk about the development and deployment of the Flexi Baffle culvert fish passage system.

«Laichzeit!»

FIBER-Workshop

Der Workshop besteht aus einem Theorieteil am Morgen und einem Feldteil am Nachmittag. Er vermittelt Neues über die Biologie, Vielfalt und Fortpflanzung der Forellen. Mit ein bisschen Glück lassen sich während dem Feldteil Forellen beim Laichakt beobachten – ein faszinierendes Schauspiel!

Ein wichtiger Gegenstand des Kurses sind die Laichgruben. Mit ein wenig Übung sind sie gut zu erkennen und lassen sich leicht zählen. Sie geben Hinweise, ob und wie gut die natürliche Verlaichung in einem Gewässer funktioniert und spielen deshalb eine Schlüsselrolle bei der Bewirtschaftungsplanung.

SGM 2021: Symposium «Limnology in Switzerland»

This symposium is part of the 19th Swiss Geoscience Meeting from 19 to 20 November 2021 in Geneva. We invite limnologists working on different systems and scales to present their research and exchange with peers. With the symposia being held in the city of Geneva, we particularly welcome contributions that show first results from the LéXPLORE platform installed on Lake Geneva. Young researchers are particularly encouraged to participate and present their results. The session will share the poster session with the «Hydrology and Hydrogeology» session to promote an integrated view of the water resource and foster interdisciplinary research.
