Dr. Aaron Spares, Research Associate
After taking a SCUBA diving course at the age of 13, Aaron became hooked on marine biology. His doctorate at Dalhousie University focussed on Salmoninae and the environmental factors that influence their marine migration (Arctic char and sea-run Brook trout (Salvelinus spp.). His MSc at Acadia University researched the open ocean migration of Atlantic salmon (Salmo salar). He has also worked on bivalve (Placopecten magellanicus) aquaculture in Mahone Bay, coral reef conservation off East Africa, Striped Bass (Morone saxatilis) and Atlantic sturgeon (Acipenser oxyrinchus) tagging in Minas Basin, and Atlantic Bluefin tuna (Thunnus thynnus) tagging off North Carolina and in the Gulf of St. Lawrence. Following a two-year post-doc fellowship with the Coastal Ecology Lab and Ducks Unlimited Canada, he continues this research investigating the impact of culverts, fishways and tide gates on movements of alewife (Alosa pseudoharengus) and American eel elvers (Anguilla rostrata). Aaron loves to travel, and has devoted his career to finding out how ‘finned travelers’ get around.

 

Current Students

tl_files/sites/cel/Our Team Photos/ColinNpenguins.jpg

Colin Buhariwalla, M.Sc. Candidate
Colin graduated from Acadia University with a B.Sc. in Biology (Co-op) in 2010. He was introduced to the joys of fisheries work studying Brook Trout (Salvelinus fontinalis) during undergrad positions at the Nova Scotia Department of Inland Fisheries. Upon graduation he garnered experience with acoustic telemetry as a research assistant with Acadia Centre for Estuarine Research working on Striped Bass (Morone saxatilis) tagging projects and deployment of Ocean Tracking Network hydrophone arrays. After Acadia, Colin worked in the Diadromous Fish Division at Fisheries and Oceans Canada with the team responsible for Atlantic Salmon (Salmo salar) assessments in the Maritime region. In 2012, curiosity led Colin back to Acadia to join the Coastal Ecology Lab. He is now finishing his MSc research on the population characteristics, seasonal movements, and origins of Striped Bass in Cape Breton, NS.  In 2016, he participated in a sub-Antarctic salmonid research expedition in the Kerguelen Islands (France).  Currently, he works at the Nova Scotia Department of Fisheries and Aquaculture -Inland Fisheries Division (Pictou).

 

Danni Harper, M.Sc. Candidate
Danni is a new Masters candidate at Acadia University in collaboration with the University of Massachusetts. She completed her BScH (Co-op program) in Marine Biology at Dalhousie University in 2016. Her Honours research partnered her with the Nova Scotia Department of Fisheries and Aquaculture to investigate anoxic/uninhabitable sediments as indicators of benthic health around aquaculture sites. She has also worked on invasive species for the Department of Fisheries and Oceans Canada, Gulf Region. Throughout her undergrad she developed a passion for field work and everything marine. Her Masters research will use video surveying to estimate abundance, density, habitat preference, and aggregation size of the sea cucumber (Cucumaria frondosa) on the Scotian Shelf. Results may provide insight towards sustainable fishery development.

 

Jillian Hunt, M.Sc. Candidate
Jill originates from Gander,the inland part of Newfoundland (Yes, there are places without a view of the ocean in Newfoundland); but she grew up in Moncton/Sackville, New Brunswick. She completed her BSc in Biology and Environmental Science at Mount Alison University in 2014. At Mount A, she was introduced to field work, mainly involving wetlands. Since graduation, she has worked as a wetlands field technician. In 2017, she commenced her Masters in our lab. Her research will focus on understanding wetland health, and specifically focus on the marine nutrient signature found in aquatic invertebrates to evaluate energy input from the ocean to freshwater via anadromous fishes.

 

 

Jessie Lilly, M.Sc. Candidate
At the age of 15 Jessie became fascinated by marine biology after being certified in Scuba Diving. She completed a BSc at the University of Alberta in 2016, and then moved out East to be closer to the ocean. Jessie started her Masters in January 2018 in the Coastal Ecology lab. Her research will focus on studying the movement of Atlantic Sturgeon through the Fundy Ocean Research Center for Energy (FORCE) test site in Minas Passage. To determine if Atlantic Sturgeon pass through the FORCE test site, the Coastal Ecology Lab at Acadia will be using new high residency (HR) tagging technology developed by VEMCO. To detect a tag, only one ping of 170 kHz from HR2 tags needs to be detected by HR receivers. These receivers will record the time, data and unique tagging ID of Atlantic Sturgeon passing through the FORCE test site. This will be one of the first uses of the tagging technology in highly turbulent environments. This information central to forming predictive models of the possible effects of in-stream turbines on Atlantic sturgeon.

 

Emma Laskey, B.Sc. (Hon.) Candidate
Emma, a native of the Annapolis Valley, joined the Coastal Ecology Lab in 2017 to begin work for her Honours. Her research will focus on whether or not alewife (Alosa pseudoharengus) are feeding during their spawning  run. She is also assisting with tracking alewife using PIT tags and readers.

 

 

 

Rachelle Breau, Research Technician (Ducks Unlimited Canada)
Rachelle has completed two years at Saint Mary's University, majoring in Environmental Science and Geography. She works for Ducks Unlimited Canada as a summer research technician, and has helped with all alewife, American eel and marine-derived nutrient projects based out of the Beaubassin Research Station. Rachelle does not use the word 'quit' and consequently has been offered multiple opportunities to do a field-based research project as part of her education.

 

 

Sarah Stewart, B.Sc. (Hon.) Candidate, Co-op Option
Sarah discovered her love for water growing up at the tip of the Bay of Fundy in Sackville, New Brunswick.

Past Students

tl_files/sites/cel/Our Team Photos/George-Sturgeon.JPG

George Nau, M.Sc.
Hailing from Maine, George studied fishway efficiency and marine nutrient transfer within the wetlands on the border of Nova Scotia and New Brunswick. He can even make alewife jump on command (see profile photo).  George's Honours project in our lab involved analysis of long-term variation in tidal cycles and their various environmental effects on fishes, as seen in historic commercial fisheries data from the Bay of Fundy. In the past, he has spent months tagging Acipenser oxyrinchus, and harvesting/cleaning fish at an intertidal fishing weir.  He is currently holding a DFO position working with Atlantic salmon.

 

tl_files/sites/cel/Our Team Photos/DSC_3827.JPG

Seth Newell, B.Sc. (Hon.), Co-op Option
Seth Newell, from Wolfville, NS, completed an Honours project examining the annuli of Atlantic sturgeon pectoral fin spines to determine age at spawning.  While in our lab, Seth spent time hunting for mini-PAT satellite pop-off tags off Cape Breton and survived the mud and scales of alewife tagging at Beaubassin.  He is currently doing his MSc in Biology at St. F.X. University, Antigonish, NS.

 

tl_files/sites/cel/Our Team Photos/LauraSturgeonReceiver.JPG

Laura Logan-Chesney, M.Sc.
In 2012, Laura joined the lab as an Honours student. Her project involved attaching a high frequency icListen hydrophone (Ocean Sonics Ltd.) to an Atlantic sturgeon (Acipenser oxyrinchus oxyrinchus) to measure ambient noise from the Minas Basin, Nova Scotia. Following her graduation in May 2013, Laura happily stayed on in the Coastal Ecology Lab for a Masters investigating potential Atlantic sturgeon spawning rivers and breaching behaviour around Minas Basin using acoustic telemetry.  She successfully defended and submitted her MSc thesis in December 2016 and graduated in May 2017.  She worked on fisheries surveys in Minas Basin for the spring and summer of 2017, and has since secured a science teaching position at a private school in Sherbrooke, Quebec, her hometown.

 

tl_files/sites/cel/Our Team Photos/MatBass.JPG

Mathieu Grégoire
Through tagging and receiver transmission data, Mat will be able to assess the effectiveness of fishways for anadromous fish installed decades ago in Nova Scotia spawning rivers.  Mat's project started off small, but soon the scope was expanded to include many spawning rivers throughout Nova Scotia.   

 

tl_files/sites/cel/Our Team Photos/Erin-1.jpeg

Erin McConnell, B.Sc. (Hon.), Co-op Option
An Acadia student from Annapolis Royal, NS, Erin completed two Co-op placement in the lab assisting with ongoing projects and completing her honours research. For her Honours, Erin studied multi-species fish movement in the Habitant River through fishways using PIT antenna tracking systems.

 

tl_files/sites/cel/Our Team Photos/Jill -sturg.jpg

Jillian Bennet, B.Sc. (Hon.)
After graduating with an Environmental Science degree in 2014 from Acadia, Jillian joined the Coastal Ecology Lab to complete an Honours thesis. Her project was based in Saint John, New Brunswick where she studied the fish population, with a focus on Brown Trout, within Little River. The Brown Trout were tagged using both PIT and acoustic tags, which allowed their movement patterns to be tracked throughout the river system. Jillian hopes to continue with her studies in aquatic ecology.

 

tl_files/sites/cel/Our Team Photos/nathan-sturgeon.jpg

Nathan Stewart, B.Sc. (Hon.)
A Biology student from Wolfville, NS, Nathan conducted his honours project on aging sturgeon from the Saint John River to determine the age-growth relationship within the population. This project was done in cooperation with researchers at the Bedford Institute of Oceanography, and its results will be useful in management of the Saint John River sturgeon fishery. Nathan moved on from the Stokesbury lab to  complete his Masters at Trent University in Ontario.  A notable accomplishment for Nathan was his authoring or co-authoring three peer-reviewed publications for work he completed during his stint in the CEL lab.

 

tl_files/sites/cel/Our Team Photos/Sam's 'By God' Catch - inner Antigonish Harbour, West River estuary, Jan'12 - Copy.jpg

Sam Andrews, M.Sc.
After growing up in Saskatoon, Saskatchewan, Sam moved out east to earn his B.Sc. in Marine Biology at Dalhousie University. His MSc at Acadia tracked the movements of alewife throughout three fishways in the Tantramar Marshes. This information served as the first step towards evaluating fish passage through anthropogenic obstructions throughout the Maritimes.  Sam is perhaps one of the most talented and addicted fishermen to survive our lab's field work.  If Sam wasn't catching fish, it was highly possible there wasn't any there. He has moved on to pursue his PhD researching Striped Bass in the St. John River Estuary.

 

tl_files/sites/cel/Our Team Photos/Jeff-sturgeon.JPG

Jeffrey Beardsall, M.Sc.
Jeff received his B.Sc. (Hon.) from Acadia University in Psychology and Biology. He studied how physiological stress responses influence fish behaviour and their adaptive function for survival. Jeff's work in the Stokesbury lab included collection of blood samples from Atlantic sturgeon (Acipenser oxyrinchus oxyrinchus). The blood samples were used to measure stress associated with two capture methods (fish weir and trawling techniques). Various physiological indicators of stress and physical activity (i.e. plasma cortisol, glucose, lactate, ions, and pH) were used to identify the capture method that minimizes physiological disturbance and the likelihood of subsequent impairments.  He also tracked long-range movements of Atlantic sturgeon in the Bay of Fundy using PAT tags.

 

tl_files/sites/cel/Our Team Photos/montana-sturgeon.JPG

Montana McLean, M.Sc.
Montana earned her B.Sc. (Hon.) at the University of Guelph, Ontario. Her research at Acadia involved the use of passive acoustic receiving technology paired with coded transmitters to investigate the movement of Atlantic sturgeon (Acipenser oxyrinchus oxyrinchus) in the Minas Basin, Bay of Fundy. Her project also involved the investigation of fine-scale movement patterns in order to examine spatial distribution using VR2W Positioning System technology. Along with gut analysis via gastric lavage and taxonomic identification of prey, she identified areas of critical feeding habitat as well as principle components of the Atlantic sturgeon diet. Montana is now working on her PhD at Dalhousie University studying White Sturgeon in the Fraser River, BC. 

 

tl_files/sites/cel/Our Team Photos/Marylise1.jpg

Marylise Lefèvre, M.Sc.
Starting out her career as a veterinary technician in France, Marylise Lefèvre, soon decided that her calling was to work as a field biologist. Among other projects, she has worked on reintroducing and tracking California condors in Big Sur, California and chimpanzees in the Republic of the Congo. After completing her B.Sc. in Wildlife Biology at McGill, Marylise worked for the Atlantic Salmon Federation research project on the Rivière Saint-Jean on Quebec's north shore, using acoustic telemetry equipments. Two years later, she came to Acadia to study the effects of environmental factors (water temperatures, diel and tide cycles) on the seaward migration of Rivière Saint-Jean Atlantic salmon juveniles and to define their emigration pathways in the Gulf of Saint Lawrence.

 

tl_files/sites/cel/Our Team Photos/sierra-receiver.JPG

Sierra Wehrell, M.Sc.
Sierra grew up near the shores of the Bay of Fundy and completed her B.Sc. (Hon.) at Acadia University. Her honours thesis was a survey of the groundfish caught by summer trawl fishery in Minas Basin and Scots Bay. This began her interest in sustainable, small community fisheries and the challenges involved in the recovery of overexploited fish stocks. After 2 years of adventures in Alaska and working for the Canadian government, Sierra returned to Acadia to start a Master's thesis. Atlantic sturgeon have been intensely studied since the 1970s but the details of their marine migration in Canadian waters remain unknown. Sierra hopes to shed some light on this aspect in this small part of the vast ocean.
