Fisheries Research and Management

Scientists from LGL have fisheries expertise working with:

  • Anadromous species (adult and juvenile salmon, Pacific lamprey)
  • Marine species (halibut, rockfish, eulachon, herring, tuna, coral reef species)
  • Freshwater species (trout, bull trout, burbot, white sturgeon)
  • Invertebrates (crab, lobster, shrimp, molluscs, bivalves)
  • Aquatic habitats (freshwater and marine)

Objectives of our research programs commonly include:

  • Distribution, abundance, and population dynamics
  • Design and implementation of harvest management plans
  • Impact assessments and mitigation strategies
  • Habitat enhancement, restoration, and management
  • Run reconstruction analyses
  • Capacity building
  • Analysis and review of complex fisheries issues
  • Bycatch analysis and mitigation

Specialized methodologies:

  • Radio-telemetry (VHF, fixed-station, mobile boat-based, mobile aerial)
  • Acoustic telemetry, 3-D analysis
  • Selective fishing methods (fishwheels, weirs, and various net-capture techniques)
  • Computer programming and simulation modeling
  • Advanced statistical analysis
  • Geographic information systems (GIS) analysis
  • Telemetry Manager (proprietary software developed and owned by LGL)
  • Hydroacoustics (including DIDSON and sidescan sonar)
  • Aerial surveys
  • Animal marking techniques (surgical [peritoneal] implants, Floy tags, PIT tags, esophageal implants, operculum tags, elastomer dyes) 
  • Underwater video monitoring
  • Tracking of fishing vessels and effort using GPS (electronic logbooks)
