This species has a history of use in the Chinese traditional medicine trade. Known as Hailong (Shi et al. 1993), it has been observed for sale in traditional medicine stores in Sydney, Australia (C. Woodfield, pers. comm., Martin-Smith and Vincent 2006). The origins of the specimens that enter the medicine trade have not been established, although it is likely there are from wild populations as S. biaculeatus rearing in aquaculture facilities has not been reported. Live specimens are also sold as pets for home aquariums and this trade could threaten wild populations if individuals are being removed from the wild to fulfill the home aquarium industry demand (S. Bartnik, pers. obs).
