Management of the Nova Scotia sea urchin fishery : a nearly successful habitat based management regime / R.J. Miller and S.C. Nolan. : Fs70-1/2000-109E-PDF

In the Nova Scotia green sea urchin fishery licensees fish either competitively, usually limited to the waters adjacent to one county, or fish restricted zones with only one license per area. There are no seasons and only a small area is regulated by quota. Restricted zones are an important part of a habitat-based management regime. In exchange for the privilege of exclusive access to fishing grounds, fishers are obligated to fully use and enhance the habitat carrying capacity. Enhancement is accomplished by manipulating the urchin stock and its food. Advantages of the restricted zones over competitive fishing are: reduced costs of enforcement and assessment, lower cost of fishing, higher value of catch, reduced barriers to sharing information, and freedom to implement a harvest plan without interference from other fishers. Disadvantages are high start-up costs, unwillingness of some fishers to release area they are not fishing, and strong opposition from outside the fishery.
