Description

Trawling is a method of fishing that involves pulling a fishing net through the water behind one or more boats. The net that is used for trawling is called a trawl. Pelagic trawling is also known as midwater trawling. This kind of trawling catches pelagic fish such as anchovies, shrimp, tuna and mackerel, whereas bottom trawling targets both bottom-living fish (groundfish) and semi-pelagic fish such as cod, squid, halibut and rockfish. Pelagic trawls are typically much larger than bottom trawls, with very large mesh openings in the net, little or no ground gear, and little or no chaffing gear.

MSP Challenge

Industrial and Pelagic Trawl Catch is a month-by-month, computer generated data layer following this fleet's fishing efforts calculated by the ecosystem simulation. This fleet doesn't fish in areas that are protected against industrial and pelagic trawl.

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).

Data Source

The industrial and pelagic fleet catch data layer comes from the EwE simplified North Sea model based on Mackinson and Daskalov 2007 and ICES WGSAM 2015 Keyrun. Ecospace based on Romagnoni et al 2015. The model was adjusted for use in the MSP Challenge by Giovanni Romagnoni.
