The Spotted Estuary Smooth Hound (Mustelus lenticulatus), also known as the rig or lemonfish, is a small to medium-sized shark species primarily found in the coastal and estuarine waters of New Zealand and southern Australia. Renowned for its mild flavor and firm texture, it is a significant target for commercial and recreational fisheries, particularly in New Zealand, where it is one of the country's most valuable inshore shark species. New Zealand leads the world in harvesting this species, with a well-managed fishery that utilizes both set nets and trawl methods, and exports much of its catch, especially to Australia and the UK. Australia also harvests this species, though to a lesser extent, mainly in the southern states. The fishing industry for the Spotted Estuary Smooth Hound is characterized by strict quotas and sustainability measures in New Zealand, ensuring the long-term viability of both the species and the fishery.
