Escolar

Escolar is also known as snake mackerel and sometimes sold as butterfish, oilfish, or white tuna. This species occurs in southern waters, mainly the Indian Ocean and around southern Africa and is caught at great depths as bycatch in tuna fisheries. World’s largest escolar supplier is Namibia.

This species looks like a large mackerel because of is long body form. Escolar has an average size of 1,5 meters and weighs on average 13 kg. In the Netherlands, escolar is mainly sold smokes or filleted. This species lives in deep waters, at 200-885 meters depth. This species has a slow reproduction rate which makes him vulnerable for overfishing.

Escolar has a high fat content (gempylotoxines) which are hard to digest. Even though it is not poisonous, consumption of gempylotoxines can lead to stomach ache and diarrhea. A good alternative to escolar is catfish.

Final assessment

Explanation assessment

The escolar or butterfish is fully exploited and is therefore under considerable pressure.

This species is often caught as bycatch in trolling or drifting longline tuna fisheries. In addition to oilfish, there is also a high level of other bycatch, including sharks, juvenile swordfish, undersized tuna, as well as endangered seabirds, turtles and small cetaceans.

The fishery for butterfish is not managed, partly due to the lack of a reliable stock estimate. Management of this species is ineffective.
