ELECTRO-FISHING

At this time of year, LLFT turns its attention to electrofishing. 

Electrofishing is a fish sampling technique using electric currents and electric fields to control fish movement and/or immobilize fish, allowing the capture of fish. Scientists use electrofishing to survey fishes and monitor the size of populations and determine the species in a community. It is an efficient capture method that can be used to obtain reliable population estimates, length-weight relationships, and age and growth on most streams. 

For the avoidance of any doubt:

  • electro fishing doesn't kill his
  • it's not as easy as it sounds
  • the entire body of water doesn't become a blanket of electricity
  • all the fish are released once they have been studied.

Initial indications for this year are that things are looking healthy, with a uniform mix of fish in terms of trout and salmon populations.
