as “…a pest to anglers”, particularly in the commercial linefishery, where the fisherman perceive these sharks to be ‘stealing’ their bait and make a point of killing the shark before discarding it. Bycatch mortality can be considered to be close to 100% in those fisheries where persecution exists (pers. obs.); therefore, fishery pressure for these species is grossly underestimated.
