Regarding Hawaii industrial longline, troll, and you may handline fisheries to own highly migratory pelagic species, both dolphinfish (mahimahi), Coryphaena hippurus, and wahoo (ono), Acanthocybium solandri, are by-the-way stuck and they are of secondary importance in order to tunas, Scombridae, and you will billfishes, Istiophoridae. Their cousin variety, field demand, and you may seemingly shorter dimensions sign up to its additional role. Yet not, because the anyone turned way more conscious about their health from the late 1970’s, combined with brand new refuse of a lot fisheries, the fresh demand for each other dolphinfish and you can wahoo increased.
