Item Considering Fish as Recipients of Ecosystem Services Provides a Framework to Formally Link Baseline, Development, and Post-operational Monitoring Programs and Improve Aquatic Impact Assessments for Large Scale Developments(Springer, 2022-05-21) Brown, Carolyn J. M.; Curry, R. Allen; Gray, Michelle A.; Lento, Jennifer; MacLatchy, Deborah L.; Monk, Wendy A.; Pavey, Scott A.; St-Hilaire, André; Wegscheider, Bernhard; Munkittrick, Kelly R.In most countries, major development projects must satisfy an Environmental Impact Assessment (EIA) process that considers positive and negative aspects to determine if it meets environmental standards and appropriately mitigates or offsets negative impacts on the values being considered. The benefits of before-after-control-impact monitoring designs have been widely known for more than 30 years, but most development assessments fail to effectively link pre- and post-development monitoring in a meaningful way. Fish are a common component of EIA evaluation for both socioeconomic and scientific reasons. The Ecosystem Services (ES) concept was developed to describe the ecosystem attributes that benefit humans, and it offers the opportunity to develop a framework for EIA that is centred around the needs of and benefits from fish. Focusing an environmental monitoring framework on the critical needs of fish could serve to better align risk, development, and monitoring assessment processes. We define the ES that fish provide in the context of two common ES frameworks. To allow for linkages between environmental assessment and the ES concept, we describe critical ecosystem functions from a fish perspective to highlight potential monitoring targets that relate to fish abundance, diversity, health, and habitat. Finally, we suggest how this framing of a monitoring process can be used to better align aquatic monitoring programs across pre-development, development, and post-operational monitoring programs.Item Freshwater mussel assemblages of the Wolastoq / Saint John River, New Brunswick: Establishing baseline population metrics and habitat associations(University of New Brunswick, 2022-02) Lippert, Emma; Curry, R. AllenFreshwater mussels are among the most imperiled animals in the world and continue to experience reductions in distributions and range, and the loss of species from communities. As keystone species and ecosystem engineers, they provide ecosystem services that benefit both the surrounding freshwater environment, e.g., protecting, and sustaining ecosystem functions and water quality. Surveys for freshwater mussels are used to learn about the status of mussel populations and the health of aquatic ecosystems, yet there is a lack of current and historical data for freshwater mussel populations in most of Atlantic Canada. Baseline population data is becoming increasingly important amid threats such as continued anthropogenic pressures, invasive species, and climate change. I present the results of extensive freshwater mussel surveys throughout the Wolastoq / Saint John River, New Brunswick, the river with the greatest freshwater mussel diversity in the Maritimes. These surveys help to establish baseline population metrics for the Saint John River and allowed me to determine associations between freshwater mussels and their physical habitat. This baseline information can be used to help better understand the basic ecology of the freshwater mussel community as well as guide freshwater mussel management, conservation, and future freshwater mussel research efforts in the Wolastoq / Saint John River, New Brunswick, and Atlantic Canada.Item Genomic population structure of Striped Bass (Morone saxatilis) from the Gulf of St. Lawrence to Cape Fear River(Wiley Open Access, 2020-07-14) LeBlanc, Nathalie M.; Gahagan, Benjamin I.; Andrews, Samuel N.; Avery, Trevor S.; Puncher, Gregory N.; Reading, Benjamin J.; Buhariwalla, Colin F.; Curry, R. Allen; Whiteley, Andrew R.; Pavey, Scott A.Striped Bass, Morone saxatilis (Walbaum, 1792), is an anadromous fish species that supports fisheries throughout North America and is native to the North American Atlantic Coast. Due to long coastal migrations that span multiple jurisdictions, a detailed understanding of population genomics is required to untangle demographic patterns, understand local adaptation, and characterize population movements. This study used 1,256 single nucleotide polymorphism (SNP) loci to investigate genetic structure of 477 Striped Bass sampled from 15 locations spanning the North American Atlantic coast from the Gulf of St. Lawrence, Canada, to the Cape Fear River, United States. We found striking differences in neutral divergence among Canadian sites, which were isolated from each other and US populations, compared with US populations that were much less isolated. Our SNP dataset was able to assign 99% of Striped Bass back to six reporting groups, a 39% improvement over previous genetic markers. Using this method, we found (a) evidence of admixture within Saint John River, indicating that migrants from the United States and from Shubenacadie River occasionally spawn in the Saint John River; (b) Striped Bass collected in the Mira River, Cape Breton, Canada, were found to be of both Miramichi River and US origin; (c) juveniles in the newly restored Kennebec River population had small and nonsignificant differences from the Hudson River; and (d) tributaries within the Chesapeake Bay showed a mixture of homogeny and small differences among each other. This study introduces new hypotheses about the dynamic zoogeography of Striped Bass at its northern range and has important implications for the local and international management of this species.Item Interannual variation in spawning success of striped bass (Morone saxatilis) in the Saint John River, New Brunswick(Wiley, 2019-11-08) Andrews, Samuel N.; Linnansaari, Tommi; Leblanc, Nathalie; Pavey, Scott A.; Curry, R. AllenBarriers such as dams have been cited as a serious threat to striped bass survival, especially when they affect or impede migration and access to spawning grounds. On the Saint John River, New Brunswick, the installation of the large Mactaquac Dam in the immediate vicinity of a historic striped bass spawning location was suspected to have caused the arrest of striped bass reproduction and the collapse of the native striped bass population. In 2014, juvenile striped bass of confirmed Saint John River origin were documented in the river for the first time since 1979. In the current study, we examined juveniles from 6 years of sampling to determine corresponding years of successful recruitment. We also tracked adult striped bass matching the ancestry of native Saint John River juveniles to determine the timing and location of spawning. Over 5 years, we observed an annual upstream migration by adult striped bass to historic spawning areas near Fredericton, identified a dominant year class of Saint John River origin juveniles reproduced in 2013, and linked the apparent successful production of year classes to definable discharge conditions, that is, extended periods of sustained flow >36 hr downstream from the Mactaquac Dam. The results of this study suggest important first management actions towards recovering and sustaining the re-discovered striped bass population in the Saint John River, New Brunswick.Item Mactaquac Aquatic Ecosystem Study Report Series 2015-001, Contract Deliverable 3.1.1.1 – Interim Report on the Predicted Hydrological Regime: Future Discharge at Fredericton (Station 01AK003)(2015) Curry, R.
