Fish Habitat Assessments
Fish Habitat Assessments
Fish habitat can be defined as those areas used by fish for feeding, reproduction, and shelter or the waterways or migration corridors connecting these specific areas. Lakes, streams, rivers, marshes, wetlands, reservoirs, canals and even ditches can be considered fish habitat. For an individual fish species, habitat requirements are often quite different depending on the life stage of the fish. For example, spawning or overwintering requirements are quite different for an individual species. At AAE Tech Services we evaluate and describe fish habitat along waterways to facilitate individuals, groups, government agencies or large corporations working around water to develop plans in order to mitigate or minimize the impact or destruction of fish habitat. Fish habitat assessments are also undertaken to identify areas in need of rehabilitation or enhancement to improve fish habitat to help sustain healthy fish populations.
St. Malo Fisheries Assessment
AAE was contracted to conduct a fisheries assessment for the St. Malo-Rat River system in Southern Manitoba. The construction of the Rat River Dam in 1959 created St. Malo Lake, which is a valued recreation destination for many Manitobans. However, the health of the St. Malo Lake fishery has been in decline in recent decades prompting local conservation authorities to tackle the problem. As such, AAE was hired to conduct a thorough assessment of the system, which includes bathymetry mapping, fisheries assessment via electro-fishing and hoop netting, riparian habitat assessment, benthic invertebrate presence/abundance, stream profiling, stream velocity measurements and in-steam fish habitat assessments. Based off the data collected, we also have provided the contractor with several recommendations to enhance fish stocks, develop additional spawning habitat within St. Malo Lake and improve fish access to the upstream Rat River high quality spawning habitat.
Whiteshell River Fish and Habitat Assessment
AAE Tech Services was contracted to evaluate fish habitat enhancements that were made twenty years prior to increase trout habitat within the Whiteshell River. Riffle elevation heights and pool depths were assessed. Fisheries inventories were conducted to assess fish utilization within the enhanced reaches of the river.
Aquatic Habitat Survey Whitefish Lake Tributaries
Whitefish Lake is a popular fishing site for many residents of Swan River. Two tributaries of Whitefish Lake, Lagoon Creek and North Creek, have historically supported large Walleye spawning runs. The local fishing group contracted AAE Tech Services to assess available fish habitat within the creeks and to provide the group with recommendations and guidelines to restore spawning habitat.
Whiteshell River Winter Fish and Habitat Assessment
Winter sampling was conducted on the Whiteshell River to better understand conditions fish face during winter. Pool depths, hydrology, ice formation, dissolved oxygen levels, and nutrient loading were assessed. Fish inventories were also conducted to document fish utilization and overwintering strategies.
Fish Habitat Assessment of Selected North Basin Lake Manitoba Triburaties
The Lake Manitoba fishery is a valuable commodity within Manitoba. AAE Tech Services was contracted to conduct an assessment on numerous north basin Lake Manitoba tributaries. The primary goals of the project were to gather baseline data documenting the aquatic habitat conditions and to compile a list of recommendations to enhance the natural spawning habitat around the lake to ultimately help restore healthy fish populations.
Lafarge Steep Rock Quarry Fish and Fish Habitat Assessment
A detailed fish and aquatic habitat assessment was conducted on the Lafarge Steep Rock Quarry to provide recommendations on developing the quarry into a sustainable catch and release fishery. A bathymetric survey was a component of the project to document habitat conditions and water depth within the quarry.
