Audience: Commercial fishers, vessel operators, skippers, and crew
Estimated reading time: 10–15 minutes


Learning Objectives

By the end of this lesson, you will be able to:

  • Understand what Electronic Monitoring (EM) is.
  • Recognize the main components of an EM system.
  • Explain how EM supports sustainable and profitable fishing.
  • Describe what happens during a fishing trip using EM.
  • Understand your responsibilities when using an EM system.

Introduction

Electronic Monitoring (EM) is becoming an important part of modern fisheries management. Rather than relying only on human observers, EM systems use cameras, sensors, GPS, and specialized software to document fishing activities.

For fishers, Electronic Monitoring is more than a regulatory requirement—it is a tool that helps demonstrate responsible fishing practices, improve data quality, and increase confidence in seafood products.

What Is Electronic Monitoring?

Electronic Monitoring is a system that automatically records fishing operations using several technologies working together.

A typical EM system includes:

  • High-definition cameras
  • GPS receiver
  • Hydraulic or drum rotation sensors
  • Control unit (computer)
  • Hard drives or secure storage devices
  • Power supply and backup battery

Together, these components create a record of fishing activity during each trip.


Why Is Electronic Monitoring Used?

Electronic Monitoring helps everyone involved in fisheries.

Benefits for Fishers

  • Demonstrates compliance with fishing regulations.
  • Reduces the need for onboard human observers.
  • Provides objective evidence of fishing practices.
  • Supports market access for sustainably harvested seafood.
  • Builds trust between fishers, regulators, and consumers.

Benefits for Fisheries Management

  • Improves catch reporting.
  • Provides accurate effort data.
  • Supports stock assessments.
  • Helps protect sensitive species.
  • Encourages sustainable fisheries.

How Does an EM System Work?

The process is straightforward.

Before Leaving Port

The skipper should:

  • Verify cameras are clean.
  • Ensure sensors are functioning.
  • Check available storage.
  • Confirm the system powers on correctly.

During Fishing

When fishing begins:

  1. The vessel leaves port.
  2. GPS records vessel position.
  3. Sensors detect fishing activity.
  4. Cameras automatically record key events.
  5. Fishing continues as normal.

The crew should continue fishing according to normal operating procedures while ensuring cameras remain unobstructed.


After the Trip

Once the trip is complete:

  • Data are securely stored.
  • Information may be uploaded or collected.
  • Authorized reviewers analyze selected footage.
  • Results support catch verification and fisheries reporting.

What Do the Cameras Record?

Depending on the fishery, cameras may observe:

  • Gear deployment
  • Gear retrieval
  • Fish coming aboard
  • Sorting activities
  • Retained catch
  • Discards
  • Protected species interactions

The goal is to document fishing operations—not continuously monitor crew behavior.
