Illegal Fishing

Slide 4 - Slide

Illegal fishing means that the fishermen enter the territorial waters of a country or regulated marine zone without permission or without a license for the fish they intend to catch. In basic terms they are stealing from these waters.
Ask students to answer the following question using www.LessonUp.app or discuss in the classroom.  

“How can a legal fishing vessel (licensed) be guilty of operating illegally?”

Introduction to IUU fishing and the impact of overfishing.
Unreported fishing

Slide 5 - Slide

Unreported means that a fishing vessel may have a license with an allocated quota for fishing a particular species, such as tuna, but then catches more than their quota and they fail to report it.

When vessels are inspected the information recorded in the fishing logbooks are compared against what is in the fish holds of the vessel to determine if the catch has been reported correctly.

Introduction to IUU fishing and the impact of overfishing.
Unregulated fishing

Slide 6 - Slide

Unregulated refers to areas in the ocean where there may not be a quota or any regulations in place, either in that location or for the type of species.

There are areas of the ocean that are not subject to any regulation, generally because they are not controlled by a particular country or form part of any regulated zone.  Fishing vessels can head to these areas knowing no one is likely to be patrolling or monitoring fishing activities.

Regulating the fishing industry is a huge task, given the size of the oceans and the scale of commercial fishing operations. There are thousands of illegal fishing vessels out at sea at any moment in time.
Introduction to IUU fishing and the impact of overfishing.
IUU fishing is approx 30% of global fishing catch

Slide 7 - Slide

The United Nations estimates that 30% of the global fishing catch comes from Illegal, Unreported and Unregulated (IUU) fishing. This amount varies by region from 15% to 40%.

Slide 8 - Slide

By-catch is basically anything that is caught in fishing nets or on lines, that the fishermen don’t want or are not allowed to legally catch.

Generally, they remove the by-catch from the nets and return it to the ocean.  However, many of these animals will have already died before they are freed. By-catch could be other species of fish, turtles, dolphins, sharks or even whales.

Slide 9 - Video

It is estimated that around 26% of the global fishing catch is by-catch.
