Aquatic Science

Expertise develops with practice and, when it comes to aquatic science, we've done our share of practising. This is one of our cornerstone disciplines, after all. As such, we can leverage everything we've learned to your benefit resulting in efficient, cost-effective and useful results. From baseline inventories to impact assessment and mitigation planning, we're prepared to design and implement a program tailored to your project needs.

Fisheries and Fish Habitat

  • Baseline data collection within lake and river systems
  • Habitat compensation and restoration including design, on-site implementation, oversight and monitoring
  • Fish and fish habitat monitoring programs
  • Fisheries research including lake trout spawning / incubation studies and Nechako and Upper Fraser River White Sturgeon populations
  • Telemetry and tracking of migration (acoustic and radio)
  • Habitat suitability assessments/modeling (includes hydrodynamic modeling)
  • Detailed fluvial geomorphic assessments, channel stability
  • Stream crossing surveys, fish passage determination, and stream classification
  • Stock assessment and population estimates (including sonar experience)
  • Fish sampling using various methods. EDI has a full-suite of sampling gear including a jet-boat electrofisher.

Watershed Studies

  • Watershed assessment to determine landscape level disturbances and hydrologic recovery
  • Terrain and terrain stability mapping
  • Watershed hydrology and modeling
  • Watershed hydrology for ungauged catchments
  • Terrain stability mapping for risk of sediment delivery to streams
  • Instream flow assessments
  • Sediment source surveys to locate and assess mass wasting occurrences and impacts
  • Riparian Areas Regulation (RAR) Assessments Riparian condition assessments with respect to stream bank stability, large woody debris input and fish habitat, and floodplain delineation
  • Digital (GPS) bathymetric mapping of lakes and large rivers

Aquatic Invertebrates, Sediment, and Periphyton

  • Drift sampling, kick net, plant hook, Ekman grab, plankton net, pelagic haul, Surber samples
  • Environment Canada CABIN methodology trained staff
  • Abundance, biomass, and taxonomy analyses

Water Quality

  • Baseline study design and implementation
  • Expertise in analyses relevant to Canadian and Provincial Water Quality Guidelines

Marine Mammals and Waterfowl

  • Breeding waterfowl surveys
  • Nest assessments
  • Population inventory


  • Underwater baseline assessments (pre-operation) and monitoring (fallow periods)
  • Sea lice monitoring and training
