The Longline fishing method is considered ideal for catching fish that inhabit deeper waters, such as albacore, bigeye and yellowfin.
Longline fisheries supply the fresh and frozen tuna markets, with many vessels also targeting other non-tuna species. Fish are caught one by one and frozen in blast freezing systems, the same freezing method used for sashimi.
Bycatch
The average bycatch rate for longline fishing is more than 20% of the total catch. Mitigation methods, such as circle hooks and tori lines, have been developed to prevent the bycatch of marine life such as turtles and birds.
Fuel Efficiency
According to an ISSF-commissioned study, the longline method burns roughly 1,070 liters of fuel to land one ton of tuna.
