In February and March hardly any vessels are fishing so that the figures
for the yield show peaks about the end of the year and in spring. The
Polish statistics shows the greatest landings from November to January
and from April to May. This separation is still more pronounced for the
Swedish fishermen from Blekinge and Gotland, who carry out a pure fall
fishery and who obtain the highest yields from September to November and
from March to May.
2.3.5. The composition of the catch in the pelagic fishery
As has already been said, the sea trout are not recorded sep-
arately in the landing statistics. In order to ascertain their shaxe one
has to have recourse to market investigations.
• The results of the available analyses have been summarized in
Table 19. There are no Swedish records for the Baltic Sea proper'. When
one assumes that the percentage of the Swedish share in seà trout ià about as
high as the Danish one, one obtains for the total catch in the Baltic Sea
proper 10 per cent in 1958/9, 25 per cent for 1959/60 , 12 percent for
[p.:259]
1961/2, and 22 per cent for 1962/3 of sea trout. In the Polish catches the
share amonted in the.last few years numerically to over 80 per cent. In
the proper Baltic 'Sea alone it ameunted to 20 per cent in the season 1959/60 . •
In any case it is astonishing that up to one quarter of the yield of the
pelagic salmon fishery consists in some years of sea trout.
The'German Catches show'from January/February on an increase
in the share of sea trout,loecause at that time the fishermen work frequ
ently in the Danzig Deep. There the sea trout that originate'in the Vistula'
occur in large numbers. The total catch. of a cutter at that time can occas-
ionally conaist tô 70 per cent of this kind. Accordin'e, to the data at hand,
the share of' seà -trout is independent of whether driftlines . -or driftnets
are being used.
