Since the introduction of 200-mile exclusive economic zones in the lat
e 1970s, Norway and Russia/The Soviet Union have shared a common respo
nsibility for management of the fish resources in the Barents Sea. At
the moment, the major fish stocks in the area are in a favourable cond
ition, partly due to a successful operation of the Norwegian-Russian r
egime. However, in the last few years, new threats to the resource bas
is have arisen. The article discusses various challenges to the curren
t regime, concluding that it has dealt properly with the issues which
fall within its competence. Above all, the control bodies of the respe
ctive states have engaged in a fruitful cooperation within the scheme
of the existing regime in order to cope with an extended Russian over-
fishing of quotas. The focal point is, however, whether Russian author
ities are in a state to implement the decisions taken in the joint for
a. A danger exists that reports - in an old Russian tradition are adju
sted to the image of ''how things should be'' rather than depicting th
e real state of affairs. Another major challenge to the Barents Sea fi
sh stocks is the unregulated fishing of third country vessels in the s
o-called Loophole. Although this is a jurisdictional question being de
bated within a UN context - i.e. in principle not an issue for the joi
nt Norwegian-Russian regime - Norway and Russia have taken a common st
and towards the third countries, thus expressing a shared responsibili
ty for the state of the fish resources.
