Chub mackerel, ''Scomber japonicus'', are the most intensively fished scombroid mackerel. They account for about half the total capture production of scombroid mackerels.<ref name=FAOdata /> As a species, they are easily confused with Atlantic mackerel. Chub mackerel migrate long distances in oceans and across the Mediterranean. They can be caught with [[drift net]]s and suitable [[trawl]]s, but are most usually caught with [[surround net]]s at night by attracting them with lampara lamps.<ref>{{cite web | title = Chub mackerel | url = http://www.sicilianfishontheroad.com/en/il-pescato-siciliano/il-pesce-azzurro/lanzardo | archive-url = https://web.archive.org/web/20130313192422/http://www.sicilianfishontheroad.com/en/il-pescato-siciliano/il-pesce-azzurro/lanzardo | archive-date = 2013-03-13 | url-status = dead | publisher = Sicilian Fish on the Road | access-date = 2012-04-06 }}</ref>

The remaining catch of scombroid mackerels is divided equally between the Atlantic mackerel and all other scombroid mackerels. 
Just these two species (Chub mackerel and Atlantic mackerel) account for about 75% of the total catch of scombroid mackerels.<ref name=FAOdata />

Chilean jack mackerel are the most commonly fished non-scombroid mackerel, fished as heavily as chub mackerel.<ref name=FAOdata /><ref name=FAOmurphyi /> The species has been [[Overfishing|overfished]], and its fishery may now be in danger of collapsing.<ref name=nytimes>

Smaller mackerel behave like [[herring]]s, and are captured in similar ways.<ref name=Clapham1941 /> Fish species like these, which [[Shoaling and schooling|school]] near the surface, can be caught efficiently by purse seining. Huge purse-seine vessels use spotter planes to locate the schooling fish. Then they close in using sophisticated sonar to track the shape of the school, which is then encircled with fast auxiliary boats that deploy purse seines as they speed around the school.<ref>

Suitably designed [[Trolling (fishing)|trollers]] can also catch mackerels effectively when they swim near the surface. Trollers typically have several long booms which they lift and drop with "topping lifts". They haul their lines with electric or hydraulic reels.<ref>{{cite web | title = Fishing Vessel type: Trollers | url = http://www.fao.org/fishery/vesseltype/360/en | publisher = [[FAO]] | archive-url = https://web.archive.org/web/20190403212959/http://www.fao.org/fishery/vesseltype/360/en | archive-date = 2019-04-03 | url-status = live}}</ref> [[Fish aggregating device]]s are also used to target mackerel.<ref name=hi>{{cite web | url = http://www.himb.hawaii.edu/FADS/ | title = The FAD FAQ | access-date = 2019-05-06 | archive-url = https://web.archive.org/web/20181029004642/http://www.himb.hawaii.edu/FADS/ | archive-date = 2018-10-29 | url-status = live}}</ref>
