Fixed gillnets consist of a sheet of network stretched on stakes fixed into the ground, generally in rivers or where the sea ebbs and flows, for entangling and catching the fish. Drift nets are nets which are not anchored. They are usually gillnets, and are commonly used in the coastal waters of many countries.
The drift and fixed nets fishing fleet is much smaller in terms of total catches than the bottom trawl or the industrial trawl. This method of fishing allows targeting the desired species and size, with reduced by-catch and discard, so this fleet has a lower ecosystem impact compared to the trawl fleets. Drift nets are deployed in the current and are allowed to float freely, while fixed nets are anchored to the sea bottom.

Description

The drift and fixed nets fishing fleet is much smaller in terms of total catches than the bottom trawl or the industrial trawl. This method of fishing allows targeting the desired species and size, with reduced by-catch and discard, so this fleet has a lower ecosystem impact compared to the trawl fleets. Drift nets are deployed in the current and are allowed to float freely, while fixed nets are anchored to the sea bottom.

MSP Challenge

Drift and Fixed Nets Catch is a month-by-month, computer generated data layer following this fleet's fishing catch calculated by the ecosystem simulation. This fleet doesn't fish in areas that are protected against drift and fixed nets.

A plan can also include a change in the fishing efforts for this fleet per EEZ. Activate the Fishing controls by ticking the appropriate checkbox under section 2b in the Plan Wizard. Subsequently change the Fishing effort sliders under the Fishing tab of the Plan Details (maximize the Plans Monitor and select your plan).

In the North Sea, the Drift and Fixed Nets fleet catches numerous of the larger species, including:

Types

  • Very Low Density
  • Low Density
  • Medium Density
  • High Density
  • Very High Density
