International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

Downstream migration of 2+ salmon smolts (Salmo salar) was studied in the Meuse in the Netherlands, in the period 2009-2013. Smolts (n =897) with implanted NEDAP transponders, were released at different locations in the lower part of the Meuse in Belgium (Berwijn, Moelingen) and the upper part of the Meuse in the Netherlands (Stevensweert, Linne), and tracked by NEDAP trail stations at 41 fixed locations distributed along the Meuse and the Berwijn to the North sea (distance more than 300 km). Over the period 2009-2013 70% (n =628) of the smolts were detected. Numbers of smolts reaching …

Session A2: Fish Migration Facilities On The Salt-Fresh Water Border Of The Wadden Sea, George Wintermans

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

From the mid 1980's onwards salt-fresh water transition area's received increasing interest from water management organizations and researchers. In this development salt-fresh water nature values and migratory fishes especially, became goals or targets in water management plans. As for fishes these plans ware based on a catchment basis approach in which the salt-fresh water transition areas were both the entrance and exit of the catchment basin. The first fish migration facilities in the transition area were constructed along the coast of the Wadden Sea and gradually spread out along the Dutch coast.

In this presentation an overview is given …

Session D2: Coimbra Fishway: Restoring Connectivity In River Mondego, Ana Telhado, João Ferreira, Felisbina Quadrado, José Proença, Carlos Batista, Bernardo R. Quintella, Pedro R. De Almeida

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

River Mondego is the largest Portuguese river with its basin entirely within national territory. The Açude-Ponte dam was built in Mondego in the 80’s, along with three other large dams to mitigate floods and to allow the integrated use of river basin water resources for hydroelectric power generation, public supply, industry and irrigation.

Considering the river importance for several fish species, namely sea-lamprey and shad, a fishway was constructed. Several structural and hydraulic problems soon revealed that this fishway was inefficient therefore this dam became the first impassable obstacle in the River Mondego. In 2011, after several years of …

Session B2: A Quantitative, Traits-Based Approach For Choosing And Prioritizing Study Species For Evaluating The Impacts Of Turbine Passage, Brenda M. Pracheil, Mark S. Bevelhimer, Glenn F. Čada, Chris R. Derolph, Ryan A. Mcmanamay

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

The choice of study species when conducting environmental assessments of hydropower facilities is of great importance from a licensing and policy perspective. Power analyses are commonly used to provide quantitative backing for the numbers of study organisms and trials used, but there is not frequent use of quantitative methods for choosing appropriate study species. Species choice can be especially important when measuring the impacts of ecosystem alteration, such as in a hydropower system, when study species must be chosen that are both sensitive to the alteration and of sufficient abundance for study. In this study, we step through two …

Session E2: Cross Border Practical And Applied Experiences With Germany; The Alosa Alosa Life(+) Project, Gerard De Laak, Dr. Andreas Scharbert

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

In 2007 a LIFE+ project aiming at the reintroduction of the allis shad to the Rhine system started by Rheinische Fischereiverband 1880e.V. and partners. Between 2008 and 2012 about eight million shad larvae were produced and transported to Germany where they have been released in the Hessian and North Rhine-Westphalian parts of the Rhine basin. In 2014, the first year after a 4 to 5 years period in the sea, hundreds of Allis Shad have been recorded returning to the Rhine system for spawning. In order to form the basis for a future allis shad stock in the Rhine, …

Session C2: How Migrating Fish Survives Between Law, Politics, And Permits For Hydropower, Marcel Van Den Berg, Harriet Bakker, Jasper Van Kempen, Dju Bijstra

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

Although hydropower is a small energy source in the Netherlands, it is often discussed in the media, among stakeholders, and in politics. On the one hand, the Dutch government promotes the development of sustainable energy. On the other hand, these projects can cause damage to migratory fish. Since the Dutch large rivers are crucial as main ports for many migratory fish species, the water manager (Rijkswaterstaat) has developed an official policy rule for a transparent decision-making on hydropower issues. The rule provides a specific framework for decision makers when assessing projects for hydropower stations. It aims to allow for …

Session A2: From Banging Your Head Into A Tidal Barrier To Migration Further Upstream. Migration Doesn't Stop At The Coastline, Peter Paul Schollema

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

For many decades the abundance of small diadromous fish has been monitored in the Waddensea region by IMARES on a small selection of locations. In 2001 Rijkswaterstaat Noord Nederland initiated a 3 year study at 23 locations to get a better spatial understanding of the abundance of diadromous fish at the different tidal barriers. This study was carried out by RIKZ and Wintermans Ecologenbureau in close cooperation with several Regional Water Authorities, professional fishermen, sport fishermen and many other volunteers. As part of the “Ruim Baan voor Vissen” project this study was repeated from 2012-2014 in order to determine …

Session B2: Certification Of ‘Fish-Friendliness’: Looking Through A Glass Darkly, Maarten Bruijs

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

The past years, improvement of fish survival at hydropower dams has shifted from development of fish guidance systems towards the development of ‘fish-friendly’ turbines. A variety of technical features of turbines is altered in order to reduce mortality of fish passing the turbine. Data on mortality rates at traditional, currently applied turbine types, shows a great variation for fish species and life stages. ‘Improvements’ applied in novel turbine types must thus be tested thoroughly, both in small-scale (laboratory) flume test as well as under real-time field condition, before any conclusion can be drawn for long term application.

The current …

Session A2: Like Shooting Fish In A Barrel: Migratory Behavior Of Fish At Intertidal Fish Passes In Dutch Wadden Sea, Jeroen Huisman

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

The Wadden Sea is a large intertidal area in the Northwest of Europe and is listed on the UNESCO’s World Heritage List (UNESCO 2009). The tributaries and estuaries in the Dutch part of the Wadden Sea are relatively small and as such have suffered extensive habitat loss and habitat degradation due to empoldering and measures ensuring flood protection e.g. pumping stations, weirs and sluices.

The Wadden Sea and its intertidal barriers offer a unique opportunity to investigate migratory behaviour of fish and fish pass functioning with regards to diadromous fish. To facilitate fish migration intertidal fish passes in the …

The Eels (England and Wales) Regulations 2009 came into force on 15 January 2010 to support the UK in implementing EC Council Regulation (1100/2007). Under this European Regulation, the UK must take actions to halt and reverse the decline in the European eel stock, aiming to meet a target set for the number of mature adult eels leaving each river basin to …

Session E2: Benefits Of New Management Of The Haringvliet Sluices And The Effects On Fish Migration, André Breukelaar

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

The Rhine West Water Council is responsible for the regional implementation of the Water Framework Directive (WFD) and contributes to the River Basin Management Plan of the Rhine. The Rhine-West river basin is situated in the most western part of the Netherlands. It is highly industrialized and urbanized. Yet it is of major ecological importance with several ecologically important areas and main open connections from the sea to the rivers of the Dutch Delta. Thus, the Rhine-West region is a gateway to Europe, both economically and ecologically.

Session B1: Lessons Learned From Tropical Storm Irene 2.0: How Flood Resiliency Benefits Of Stream Simulation Designs Are Changing Policy Within The U.S., Nathaniel Gillespie, Robert Gubernick, Dan Cenderelli, Mark Weinhold, Brian C. Austin, Daniel Mckinley, Amy Unthank, Kurt Gernerd

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract

Stream simulation design is a geomorphic, engineering, and ecologically-based approach to designing road-stream crossings that creates a natural and dynamic channel through the crossing structure similar in dimensions and characteristics to the adjacent, natural channel, allowing for unimpeded passage of aquatic organisms, debris, and water during various flow conditions, including floods. A retrospective case study of the survival and failure of road-stream crossings was conducted in the upper White River watershed and the Green Mountain National Forest in Vermont following record flooding from Tropical Storm Irene in August 2011. Damage was largely avoided at two road-stream crossings where stream …

Session D1: Towards Effective, Bi-Directional Selective Fish Passage, Thomas Pratt, Rob Mclaughlin, Andrew Muir

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

Barriers interfere with aquatic connectivity by preventing or limiting migratory fishes from spawning and other life history processes, and there is increasing pressure to restore connectivity. However, conflicting management objectives exist in many jurisdictions where barriers to fish movement inhibit the restoration of native fishes but protect native fish communities above barriers from undesirable invasive species. In the Laurentian Great Lakes, barriers are an important management tool in the control of invasive Sea Lampreys. Sea Lampreys remain highly destructive in the Great Lakes, and are a constant threat to a 7 billion dollar fishery. Developing selective, effective bi-directional fish …

Session D1: Experimental Study On Flow Patterns In Vertical Slot Fishways, Verena Höger, Martin Henning, Franz Nestmann

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

The vertical slot fishway is one of the most commonly used fish passage facilities in Germany. The flow conditions within fishway play an important role in the establishment of ecological connectivity, because they determine whether fish can pass, with regard of their given swimming performance.

Earlier studies have shown that two different types of flow patterns, separated by a transition area, may develop in the pools depending on the width-to-length (B/L) ratio of the pools and the slope of the fishway.

In order to gain insight in the formation of different flow patterns, an extensive study of different geometric …

Session A1: Effects Of Sluices On Migrating Elvers And Other Fish In A Dutch Salt Water / Fresh Water Gradient, Bas Van Den Boogaard, Joost Bergsma, Bart Schaub, Lucienne Vuister

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract

Many of the formerly gradual transitions between marine and freshwater habitats have been severely altered by man-made constructions. In the Netherlands, water managers are implementing numerous measures to decrease the negative effects of these barriers on fish migration (e.g. constructing fish passages). Adjusting sluice management to restore a salt water / fresh water gradient, however, is a novel way of accommodating fish migration. To effectively apply this measure, more knowledge is required on how fish migration is influenced by sluices.

At Spaarndam (the Netherlands), a complex of pumping stations and sluices separates salt water and fresh water. Within this …

Session B1: Fish Passage In Large Rivers: Challenges And Solutions, Walter Reckendorfer, Gerd Frik, Roland Schmalfuss, Sabine Käfer, Gerog Loy

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract

Understanding and facilitating fish passage in large rivers is a major challenge. This challenge stems in part from the scarcity of surveys of large river, due the inherent difficulties associated with studying them. In addition large rivers host a great number of fish species differing in size, ecological requirements and swimming abilities. Notwithstanding the limited information regarding these topics, EU and national legislation require passage facilities for all species and size classes to reach the “good ecological status” till 2027.

VERBUND, the largest power plant operator in Austria, is responsible to implement these measures on a variety of big …

Session B1: Fish-Friendly Management Of First Dams In The Tidal Area Of The Gironde Estuary (France, Sw), Vanessa Lauronce, William Bouyssonnie, C. Rigaud

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract

The particular case of the first dams met by the European eel migrating in the tidal area of the Gironde estuary is examined here. For these obstacles, typological elements are proposed, based on the nature of the hydraulic dams, but also on that of its downstream and upstream areas. Various technical tries are already performed to minimize impact of these dams, in tidal areas. These obstacles exist to prevent and limit entrance of salt or brackish water in the swamp and to prevent floods. Glass eel and tidal and marine young species colonize theses areas carried by the stream. …

Session C1: Assessing Longitudinal Connectivity Affected By Cross-Sectional Barriers In A Riverine Bidirectional Network, Gonzalo Rincón Sanz, Carlos Alonso, Joaquín Solana, Santiago Saura, Diego G. De Jalón

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

Disruption of longitudinal connectivity is a main problem in most of the world rivers. Spain, as a country with one of highest rates of cross-sectional obstacles per river, needs a strategy to restore longitudinal connectivity in riverscapes. Graph theory based approaches have proven as a suitable tool to measure the connectivity in the landscape. Unlike terrestrial habitats, where it has been profusely used, riverine systems still remain scarcely studied under this focus. There is a need to adapt the currently available knowledge on terrestrial habitat connectivity assessment to the management of river networks. In our study the broadly used …

Session D1: Modelling The Efficiency Of A Vertical Slot Fishway For Anadromous Fishes, Gabriela R. Cardoso, Ana F. Belo, Catarina S. Mateus, Carlos M. Alexandre, Esmeralda Pereira, Ana Telhado, João Ferreira, Felisbina Quadrado, Bernardo R. Quintella, Pedro R. Almeida

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

Several types of fish passage are increasingly being installed in river barriers to restore the longitudinal connectivity of fragmented riverine habitats. A vertical slot fishway installed in the Açude-Ponte weir at Coimbra (River Mondego, Portugal) was monitored to model the efficiency of this infrastructure for anadromous fishes (i.e., sea lamprey Petromyzon marinus L.; allis shad Alosa alosa L. and twaite shad Alosa fallax Lacépède, 1800) throughout 2013 and 2014 spawning seasons.

Fish passage was assessed using a video recording system. Simultaneously, eight abiotic parameters, considered as potential predictors of fishway’s use by anadromous fishes, were continuously recorded during …

Session D1: Classification Of Flow Patterns In A Nature-Oriented Fishway Based On 3d Hydraulic Simulation Results, Rebekka Czerny, Peter Oberle, Franz Nestmann

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

In order to fulfill the requirements of the EU Water Framework Directive concerning the restoration of fish passage in rivers, various types of (near-natural and technical) fishways have been built in recent years. For optimization of planned structures as well as for monitoring of the performance of existing fishways, their hydraulics has to be studied. 3D hydrodynamic numerical modelling is a useful tool to predict hydraulic quantities and analyse flow pattern. Many studies using hydraulic simulations deal with technical fishways. In contrast, nature-oriented fishways have rarely been numerically modelled so far.

In the framework of R&D activities at Karlsruhe …

Plenary Speaker: Universal Lessons From Fish Passage Research, Design And Application In Australia, Martin Mallen Cooper

International Conference on Engineering and Ecohydrology for Fish Passage

Dr. Mallen-Cooper has been a specialist fishway biologist for 30 years and has designed over 200 fishways in Australia and overseas, from fish locks and fish lifts on large dams to low-level pool-type and nature-like fishways. His approach to projects is to clarify ecological function, develop migration models and integrate fish behavior into all aspects of dam, weir and fishway design. A key aspect of this is integrating biology, hydrology and hydraulics, which has led to new approaches and applications in fishway design and improved ecological function.

In the last 10 years Dr. Mallen-Cooper has had a significant focus on …

Plenary Speaker: Fish Passage In An Era Of Broken Rivers: New Approaches A Reason For Hope?, Zeb Hogan

International Conference on Engineering and Ecohydrology for Fish Passage

Abstract:

Fish passage in an era of broken rivers: new approaches a reason for hope?

In an era of decline of large-bodied, migratory fishes, river connectivity has been shown to be increasingly important for the conservation of native biodiversity. From North America to Asia, Europe to South America, issues with river connectivity influence – for better or worse - the life cycle, and population status, of migratory fishes. In the Mekong River Basin, the world’s largest fishes, including the Critically Endangered Mekong giant catfish Pangasianodon gigas and giant pangasius Pangasius sanitwongsei, face extinction because of mainstream dams on the lower …
