Electrofishing Services

Peninsula Environmental provides fish exclusion, removal and relocation, including electrofishing services to tribes, private and public industry.

Our team of biologists, equipped with Smith-Root’s LR-24 Backpack Electrofisher, are prepared to work in a variety of locations on the Olympic Peninsula and Puget Sound region to sample fish populations for a variety of client needs. We’ve worked on fish barrier removals, logging road installations and fish sampling projects.

Who We Serve

  • Public and private construction
  • Fish barrier removals
  • Logging
  • Tribes

What We Do

  • Fish exclusion via electroshocking, gillnetting, and trapping
  • Underwater SCUBA and snorkeling surveys
  • Safely work in a variety of environments within a spectrum of water environments
  • Minimize and eliminate potential harm to fish
  • Efficiently capture fish using proper electrofishing settings
  • Employ techniques and settings for a variety of target species in different life stages


  • We use industry standard electrofishing equipment, the Smith Root LR-24. This electrofishing unit has variable voltage that can be fine-tuned for working with listed species: voltage can be adjusted to 5 volt increments, frequency in 1 Hertz increments, and duty cycle (pulse width) in 1% increments.

What is fish exclusion?

Projects that require in-water work often require safe fish exclusion practices. Work typically requires removing and relocating any aquatic organisms from the in-water work area and making sure they remain out until work is complete.

Projects such as culvert replacement, fish barrier removal, and stream realignment typically require fish exclusion services. Whenever fish-bearing or potentially fish-bearing waters are dewatered prior to construction a fish exclusion plan and process are required. Impacts to water quality, like turbidity, or injury to fish may also require fish exclusion even if the work area is not fully dewatered.
