 While large enough to perhaps be dangerous , the bignose shark seldom comes into contact with humans due to its preference for deep water . This species is a bycatch of gillnet , bottom trawl , and deep @-@ set pelagic longline fisheries ( particularly those targeting tuna ) in many parts of its range . It is regularly taken in Cuban waters and used to produce liver oil , shagreen , and fishmeal . Elsewhere , such as in Southeast Asia , the meat is consumed and the fins shipped to East Asia for shark fin soup . The bignose shark is not used commercially in United States , where it is listed as Prohibited Species under the 2007 Fishery Management Plan for Atlantic tunas , swordfish and sharks , or in Australia .
