The Isle of Man in the British Isles is famous for the queen scallop, or "Manx queenie" as it is known locally. Due to the vagaries of landings over the years, Manx fishermen have worked on technical conservation regulations, in order to ensure that stocks of the queenie have remained robust. These have included restrictions on fishing times, closed seasons, and limitations on the number of dredges permitted. There are also two conservation areas in the island's territorial waters; one has been in place since 1989 and the other was created in 2008; these areas are closed to mobile fishing. These conservation areas are supported by the fishing industry; the fishermen themselves started the initiative to create the Douglas closed area. Data analysis appears to support the viability of these areas, which appear to help ensure that the Manx queenie can be fished sustainably.
