Memorial University political science prof David Close threw some cold water on people who think "custodial management" is a simple answer to fisheries problems.
Close said while CM is easy to advocate it is almost impossible to achieve. He said it is not at all clear that Canada could unilaterally lay claim to waters outside the 200 mile exclusive economic zone.
If that isn't good enough for you, there's a slightly different view from the dean of the Dalhousie law school. it adds up to the same thing, though: CM is easy to say but hard to do.
