Fish Passage Design, Construction and Monitoring

This would be where I would add some text to give context to these publications. Did you author/co-author? What’s in them and how are they important to the user?

2017 Glenore Weir Cone Fishway Monitoring Report

The Glenore Weir Fishway project was initiated to meet the legislative requirements for the continued provision of fish passage in the Norman River as part of the raising of Glenore Weir. The major specific objective of this report was to evaluate the success of the new cone fishway technology constructed on the new weir. In the 2017 wet season, monitoring of the cone fishway was completed. In total, 27 species of fish were collected from the cone fishway, meeting its original design objectives of providing passage for the migratory fish community of the Norman River. In fact, the innovative cone design passed thousands of fish from a wide range of fish species and size ranges.

Fitzroy Barrage Cone Fishway Upgrade and Monitoring Report

The Fish Friendly Fitzroy: Bypassing the Barrage project was initiated to improve fish passage in the lower Fitzroy Basin and restore fish communities in the lower 150 km of stream habitat. The major specific objective was to evaluate the success of an innovative new cone fishway technology as well as remediate the existing vertical slot fishway to enhance upstream passage of super-abundant small-bodied fish (<100 mm long). From 2014-16, monitoring of the two major modifications (i) new cone fishway, (ii) tailwater stabilisation pool, to increase functionality of the new cone and existing vertical slot fishway was completed. In total, 19 species of small-bodied fish were collected with the cone fishway meeting its original design objectives of passage of very small native fish. In fact, the innovative cone design passed the most fish per hour of any Australian fishway and the work also significantly extended the functionality of the vertical slot.

Prioritising Barriers to Upstream Fish Passage – Barwon and Moorabool Catchment

A barrier prioritisation process was refined and adapted specifically for the Barwon and Moorabool catchment to identify and recommend ecological, social and resource-efficient priorities. The prioritisation demonstrated that while there are hundreds of barriers within the catchment, remediation of a small number of the highest priority barriers will significantly increase the habitat available to migratory fish. A strategic restoration approach is recommended herein which will greatly aid in restoring access to the different aquatic habitats of the Barwon and Moorabool catchment, along with recommendations for a series of well-known and innovative fishways for the Corangamite CMA to take forward.

2018 Achieving fish passage outcomes at irrigation infrastructure; a case study from the Lower Mekong Basin

Irrigation infrastructure expansion threatens the diversity of freshwater fish worldwide by creating migration barriers which can block access to important nursery, feeding and spawning habitat. Lao PDR is a landlocked country situated within the Lower Mekong River Basin where there is a substantial dependency on rice and fish for food, income and livelihoods. The country is experiencing an unprecedented boom in irrigation infrastructure investment, with modernisation programs being implemented in every province. Despite significant investment in infrastructure upgrades, and the potential impact on freshwater fish, little consideration has been given to fish passage solutions. In 2008, we commenced a fish passage program in Lao PDR. The intent of this case study is to outline the pivotal elements of the program of knowledge development and transfer, in the context of river connectivity and fisheries management in Lao PDR. We also highlight challenges in international research in development and lessons learned

2019 Fish passage developments for small-bodied tropical fish: field case studies lead to technology improvements

In tropical coastal lowland rivers, there are frequent upstream migrations of post-larval and juvenile diadromous fish from estuaries into freshwater. Tidal barriers completely block these pathways and have contributed to major losses of freshwater biodiversity. In northern Australia, early efforts to improve tropical river fish passage with salmonid-style fishways completely failed. Since the mid-1990s, low gradient vertical-slot and rock fishways improved fish passage, but the smallest and most abundant fish (i.e. from 10 to 100 mm long) often still failed to ascend. Since the mid-2000s, there was a paradigm shift in hydraulic design criteria for new fishways, with a renewed focus on: (i) low turbulence, (ii) maximized roughness and hydraulic boundary layers to optimise fish ascent. The success of these new designs for passage of very small (from 9 mm long) diadromous fish on low head barriers (i.e. <3 m high) was assessed by developing a conceptual model of fish movement to inform fishway design criteria, tabulating past and present fishway design criteria, and conducting a series of brief field case-studies. It was concluded that while there have been improvements in passage of small-bodied fish at tidal barriers, further experimental work is still needed to test and refine current eco-hydraulic fishway design criteria.

2012 Waterpark Creek Fishway Project

Waterpark Creek Weir was ranked the 16th most important barrier to fish passage in the 2008 Barrier Prioritisation and a vertical slot fishway was constructed in September 2010. Pre- and post-construction fish community sampling revealed an increase in overall species abundance and diversity. Fish between 21mm and 600mm successfully ascended the fishway, including both juveniles and adults of a range of species.

2010 Amity and Bridge Creeks Fish Passage Project

Amity Creek (ranked 3rd highest in priority) and Bridge Creek (ranked 25th highest in priority) were chosen for remediation following the 2008 Prioritisation report. In May 2009, a partial width rock ramp fishway was constructed on the concreted rock fill causeway located on Amity Creek, while a culvert baffle fishway was constructed on the road crossing over Bridge Creek. Fish community sampling was undertaken before and after the construction with results demonstrating that the partial width rock ramp fishway on Amity Creek is successful at passing juvenile and adult migratory fish species. A total of 397 fish between 12 and 321 mm successfully ascended the fishway, with small prey species and juvenile diadromous species making up the majority of the catch. Over 84% of the native freshwater fish species recorded upstream of the fishway in Amity and Bridge Creeks were recorded using the fishway.

2008 St Lawrence Wetland Fish Passage Improvement

In 2007, two rock ramp fishways were constructed at the St Lawrence wetlands to facilitate fish passage over the tidal bund between the estuary and the freshwater wetland. Post-construction sampling revealed a four-fold increase in total catch, and increases in species diversity and relative abundances.

2013 Moores Creek Fishway Sampling Report

In July 2012, a partial-width rock ramp fishway was constructed to remediate a pipe culvert causeway that was acting as a barrier to fish passage on the lower reaches of Moores Creek in the centre of Rockhampton. Fishway sampling results confirmed the fishway was successful at passing both juvenile and adult fish, including bottom and surface dwelling species, larval (long-finned eel), post larval (sea mullet) and juvenile (barramundi) life history stages.

2015 Fitzroy Basin Fish Barrier Prioritisation Update

The 2015 project updated the progress of installing fish passage at barriers, to provide refined guidance for future remediation works and to assess achievement against targets set in the Fitzroy Water Quality Improvement Plan

2008 Fitzroy Basin Fish Barrier Prioritisation Report

The first comprehensive fish barrier prioritisation project undertaken in the Fitzroy Basin and only the second undertaken in Queensland at this scale. The primary objective of the prioritisation was to provide a list of priority instream barriers in need of fish passage remediation in the region.
The project led to the installation of fishways at instream barriers throughout the region including Amity, Moore’s and Waterpark Creeks. See Ferguson et. al. 2008, Moore and Marsden 2010, Moore and Marsden 2011, Donaldson et. al. 2012 and Moore and Marsden 2013.
