 Across much of its range, it is a frequent catch (intentional or not) in bottom trawls and probably also set nets and demersal gillnets; the meat is eaten and the rough skin is made into a type of leather called shagreen for use in wood finishing.Angel sharks in general are highly threatened by commercial trawl fisheries due to their susceptibility to capture and low rate of reproduction, and angel shark species elsewhere are known to have declined markedly under fishing pressure.Trawling activity in the Yellow Sea and other parts of the northwestern Pacific is intense and, coupled with pollution, has had a serious impact on the local ecosystem.
