Description: 

Electrofishing is an effective way to sample freshwater fish populations. However, electrofishing may cause fish injury or mortality. Proper balance between efficient sampling and minimal harm is achieved through the knowledge of electrofishing principles and proper use of the techniques and equipment available.

This three-day course will cover the principles and practices for boat electrofishing through two classroom days and one field day during which the concepts discussed in class will be demonstrated and practiced by attendees. The class will be taken on an electrofishing equipped craft, and each person will have the opportunity to practice using the boat-based electrofishing system.

This field day exercise provides attendees with real-world experience applying the concepts discussed in the classroom. The combination of classroom lecture, field demonstration, and participation exercises gives attendees the knowledge and basic experience they will need to safely and effectively electrofish.

"Learning about the theory behind shocking made understanding the techniques much easier. The course felt cohesive, and the order in which subjects were presented made for easy comprehension." James C., May 2016

"I liked how the instructor showed us how the principles of the course could be applied practically to our sampling." Anonymous, May 2016

"Great information for operating electrofishers & background understanding of how they work and why." Mollie O., May 2016

"This seems to be a good course for both beginners and experienced e-fishermen...I appreciated the calibration of the boat to illustrate the concepts in class. Also, the feedback session on the third day helped/answered real world questions." George S., May 2016
