Popis: | During the past 40 y, commercial production of softshell clams,Mya arenaria, in the soft-bottom intertidal zone in Maine, United States, has decreased nearly 75%whereas dockside revenues have increased ca. 200%. The fishery is comanaged by coastal communities (some individually, some working together as a regional unit) and the state of Maine acting through its Department of Marine Resources. A number of shellfish management tools are available to clammers and stewardship committees to help increase or improve harvests. One of these, used by some communities, is the “conservation closure.” This is when large acres of mudflats (sometimes≥200) are closed to harvesting and fallowed for periods as long as a year because either the area is no longer productive, too few legal size clams (≥50.8-mm shell length) exist, or the community wishes to practice some direct measure to improve harvests such as transplanting clams from one area of the intertidal to another.
