INVESTIGAT10NS IN FORTE, 1895,
—
The total for cod was 1,14:7 or 15 per haul, an average
one under the previous year. All were saleable except 56. The
.average is 8 above the favourable year of 1887, and third in the
list, the highest having occurred in 1890, when 23 per haul were :
captured.
The small trawl of the “ Garland
”
was little
‘
for successful cod—shing, the more so as work was carried on
solely by day.
In the 14:th Report a slight increase (of °7) is
…
stated to have occurred in the last ve years of the period, but ; —
this is just what would have been expected with so great a pro—
_
portion of the hauls during the winter months when cod specially,
abound in the Forth audits neighbourhood. Consequently, :
high gures for this sh are found in November, December
_
and January.
A glance at the monthly periods and hauls
(Table XI.) will show the essential difference between the two,
periods of ve years in this respect. If it had.been said. that_
out of the three highest monthly totals tWo of these occurred in”_
the latter ve years, and thus was an evidence of increase of
the species following the closure, perhaps the argument would
have been more convincing. As it stands, the inuence of the
,elosure on this species in the Forth is not appreciable. Like
other shes, constant pursuit tends to render it more wary, and
tobreak up the shoals in the nearer waters, but the ub1qu1tous
distribution’and the enormous powers of reproduction,
with the curious migration of the very young cod to the lamina—
rious région, seem to be sufcient to enable the species to hold
In the monthly totale (Tables XI. and XII.—') during the
'
decade of the “Garlahd’s ” work in the Forth, January commences
with a .proPortionally high gure (990), higher, indeed, ‘ than
'
any of the previous shes (viz.
whiting, plaice, dàb,
