The consumptive use of wild species is an important aspect of the relationship between humans and the marine environment. For consumption to be sustainable, its conditions must be consistent with conservation.
As one way of fostering those conditions, the concept of rotating closed areas -- alternately closing and re-opening areas to fishing, allowing time for stocks to rebuild after each open season -- has gained the recent attention of some fisheries managers. In the northeastern US scallop fishery, for example, areas that have been closed for half a decade were re-opened this summer for huge catches; the fishery's managers are now considering re-opening the areas every 3-4 years. With managers and researchers elsewhere considering the idea, this could be an emerging trend in fisheries management.
A closed area of the ocean -- even one re-opened cyclically for fishing -- fits most definitions of "marine protected area," including that of the IUCN (MPA News 1:4). The idea of re-opening a closed area to fishing may be unacceptable to conservationists who favor permanently closed areas for the protection of biodiversity. But some managers suggest that such re-openings could be a way of securing buy-in from the fishing industry on the use of various kinds of MPAs.
