Updated Mar, 2021
Dear partners and stakeholders:
On behalf of the FishPass team, I am pleased to provide the March 2021 update.
Engineering Design / Construction:
- While on-site work is still on hold pending results of the ongoing legal process, the prime contractor, Spence Brothers Construction, has continued to prepare and submit contract submittals for review by the U.S. Army Corps of Engineers and AECOM (Designer of Record).
- Drs. Dan Zielinski, Andrew Muir, and Marc Gaden led a special topic in the Journal Aquaculture and Fisheries on global fish passage issues. The special topic contains studies from around the world and their unique solutions to provide fish passage at dams and barriers. All articles are freely available at: https://www.sciencedirect.com/journal/aquaculture-and-fisheries/vol/6/issue/2.
- The Dual Frequencies Identification Sonar (DIDSON) was re-installed on 17 March at the DNR fish weir to further expand a hydroacoustic data set passively documenting fish entry in the river. This system has been operated during 20 March to 1 June from 2017 to present. Telemetry systems monitoring fish movement and surveys of fish movement behavior continue as usual. In depth analysis of fish movement data has been ongoing with a recent emphasis by Assessment Biologist, Reid Swanson to analyze movement patterns and timing of movements in the lower river. An example detection history of a tagged white sucker Catostomus commersonii is provided below in Figure 1.
- Numerous sampling efforts are planned for this spring to account for COVID-19 related delays to the 2020 research schedule. Of particular importance is the implantation of acoustic transmitters in smallmouth bass Micropterus dolomieu, longnose sucker Catostomus catostomus, and white suckers. A total of 120 transmitter tags will be surgically implanted into these fishes allowing researchers to track movements of fish into and out of the Boardman River, Grand Traverse Bay, and greater Lake Michigan. The project team will also be collecting additional samples for isotope analysis in support of ongoing research projects investigating both contaminate transfer and nutrient subsides from fish spawning migrations.
