of Bothnia. In the fall the fleet moves southwards to fish the region
between Gotska Sand8 and bsel, as well as the eastern Gotland Basin. In
the fall of some years good catches are made also near Visby and bland.
During the main period for line fishing (December to February) the
Danzig Deep, bounded by the cornerpoints Rixh8ft, Mittelbank, Memel, and
Kahlberg still remains the most important fishing ground. During this time
fishing also takes place neax Bornholm. With this the entire Baltic Sea
between about 54 ° N and 63 ° N serves as fishing ground for the driftnet and
driftline fishery. The Gulf of Finland and the region west of Bornholm
have hitherto not been fished (Fig. 6).
2.3.2. The fishing season
For biological and climatological reasons two fishing.periods
have to be distinguished during the course of the year: the summer, with
small landings, and the colder season with good yields.
Because windy and stormy weather predominates during the period
of best harvests, hitherto only driftlines• have been used exclusively.'
During spring and later also during fali, fishing with driftnets predomin-
ated. The Danish fishermen prefer this division until the time'of writing,
because the driftline fishery still plays an important role for them.
Fishing from Gotland is carried out in a similar manner. In contrast,
driftline fishing is of little importance for the Swedjàh cutters fro*
Blekinge. There driftnets are the main gear. Until 1960 the fishing aeason
for the German cutters was divided in a manner similar to that in Denmark.
After the introduction of synthetic nets one switched, however, more and
more to driftnet fishing also during the winter.months. Since then, salmon
fishery is being carried out from August to June predominantly with dxift-
'nets, line fishing, however, is being used only during the winter mdenths,
