A growing number of fly anglers now practice catch and release in
Norway and other Scandinavian countries, but the vast majority of
anglers in those countries still fish mainly for the pot. At least
those I have met and seen etc. One also occasionally reads about it on
various boards and in magazines etc. Although it would doubtless be
very difficult to determine absolutely. In quite a few places the
decline of fish stocks has lead to a change of attitude in regard to
catch and release. It is a moot point whether it actually makes much
a of difference of course.Although obviously every sizeable fish
released and not killed does make some difference to the breeding
stock,.

In that particular film, the fishery shown is a very young fishery,
bass have only been found there in the last ten years or so, as a
result of the water warming up.

Around the UK coast, where bass are also found, the majority of fly
anglers also release them. This is also because bass are slow growing
fish, and taking too many would jeopardise the fishery very quickly.
Indeed, commercial fishing has already seriously jeopardised the
fishery in many places, resulting in far fewer fish, and a much lower
average size.

A growing number of fly anglers are not usually pot fishermen per se
anyway. This also depends somewhat on the species being targeted.
Fish like mullet and bass are invariably released.
