Biological Monitoring

alt


AAE Tech Services Inc. is experienced in the collection and analysis of data to better understand ecological changes to ecosystems over time. Ecological and biological monitoring programs are typically designed to evaluate both positive and negative human impacts on the environment, including changes to invertebrate, plant, fish and wildlife populations. Water quality sampling, sediment sampling, and habitat assessments are additional components common to many monitoring programs.

Representative Projects

 

Pigeon River Bridge Construction Lake Whitefish Spawning Survey

AAE monitored fish spawning on the Pigeon River during construction of Pigeon River Bridge B5. Fish were captured upstream and downstream of the bridge daily using gill nets to determine if bridge construction activities were negatively impacting fall and winter-spawning fish species such as Lake Whitefish.


Whiteshell River Survey

The Whiteshell River project evaluated changes to the river made twenty years prior to improve habitat for trout and other fish species inhabiting the river. The study was designed to compare riffle elevations, pool depths, and habitat from the original study (conducted in 1990) to current conditions.

 

Rusty Crayfish Monitoring on Falcon Lake, MB

Rusty Crayfish (Orconectes rusticus) is an invasive species that was discovered in Falcon Lake, MB by M. Lowdon in 2007. This was the first time a Rusty Crayfish was discovered in Manitoba waters. In 2009, Manitoba Water Stewardship initiated a monitoring program on Falcon Lake to better understand the impacts this invasive species would have on our native fish, plant and invertebrate communities.

 

Minnedosa Spawning Shoal Investigations

A three-year monitoring program was conducted at Lake Minnedosa, MB, to evaluate the effectiveness of a spawning shoal constructed as compensation for embankment stabilization works. The spawning shoal was designed to increase fish spawning habitat within the Lake. Egg mats and kick sampling were the methodologies used to assess egg deposition. Additionally, trap netting and gill netting were incorporated into the study to assess fish utilization of the spawning shoal.

 

Little Grindstone and Moose Lake Spawning Shoal Investigations

Small Craft Harbours built breakwater structures to protect the harbours at Little Grindstone, MB on Lake Winnipeg and at Moose Lake, MB. To compensate for the destruction of fish habitat, spawning shoals were built along the breakwater structures. AAE Tech Services Inc. was hired to conduct a three-year monitoring program to assess the effectiveness of the newly created spawning habitat on each breakwater structure.

  

 

Goodman's Landing and Matheson Island Spawning Shoal Investigations

Small Craft Harbours built breakwater structures to protect the harbours at Goodman's Landing and Matheson Island on Lake Winnipeg.  To compensate for the destruction of fish habitat spawning shoals were built along the breakwater structures.  AAE Tech Services was hired to conduct a three-year monitoring program to assess the effectiveness of the newly created spawning habitat on each breakwater structure.

 

Walleye Spawning Survey Basket River

Basket River is a north basin Lake Manitoba tributary. Historically, the river sustained large walleye runs, but beaver activity limited fish access throughout the river. Beaver dams were removed and thirteen riffles were constructed within the river to restore spawning habitat. AAE Tech Services was contracted to conduct a Walleye spawning survey to document successful upstream larval emergence and to determine numbers of fry produced within the river. 

 

Walleye Spawning Survey Bear Creek

Beaver dams were removed and three spawning shoals were built to increase spawning habitat within this north basin Lake Manitoba creek. AAE Tech Services Inc. was contracted to evaluate the effectiveness of the newly constructed spawning shoals and document changes to the river that took place once all the barriers were removed. Fish surveys were also conducted to determine the species utilizing the restored creek.
