Description:
Mackerel is a common name applied to a number of different species of pelagic fish, mostly, but not exclusively, from the family Scombridae. They are found in both temperate and tropical seas, mostly living along the coast or offshore in the oceanic environment.
Mackerel typically have vertical stripes on their backs and deeply forked tails. Many species are restricted in their distribution ranges, and live in separate populations or fish stocks based on geography. Some stocks migrate in large schools along the coast to suitable spawning grounds, where they spawn in fairly shallow waters. After spawning they return the way they came, in smaller schools, to suitable feeding grounds often near an area of upwelling. From there they may move offshore into deeper waters and spend the winter in relative inactivity. Other stocks migrate across oceans.

MSP Challenge 2050:
In the MSP Challenge Game the Mackerel population is part of the Ecological model, driven by Ecopath with Ecosim.
Impact from different pressures:
The following table shows the impact different pressures have on the Mackerel biomass.
| Pressure | Impact |
|---|---|
| Noise | 1: low impact |
| Surface Disturbance | 0: no impact |
| Bottom Disturbance | 0: no impact |
Impact from different fleets:
The following table shows the t/km2 mackerel the different fleets catch.
| Fleet | t/km2 |
|---|---|
| Bottom Trawl | 0,008 |
| Industrial and Pelagic Trawl | 0,210 |
| Drift and Fixed Nets | 0,000 |
