INVESTIGATIONS IN FORTE, 1889 AND 1890.
141
dabs was below (by 3) that of 1888.
Cod and gurnards re—
mained. about the same in each year, as did others.
The
increase in the number of the “ witches ” in this and the
previous year is a fact of interest.
All the Stations except IV., VI. and IX. showed a reduction
in the average
of the food—shes captured.
Station IV. had
only an increase of 6, yet this was the highest average (272)
-
of the year.
The increase per haul at Station VI. was 31, and
at Station IX. only 8.
_
In contrasting the diminished averages of 1889 with the
previous year it must not be forgotten that the former has the
disadvantage of including ve winter months in its working—
period, whereas the latter has but two. Under these circum—
stances it is perhaps remarkable that the reduction was not
Î
greater. Yet such does not indicate that a serious diminution
of the shes of the area had taken place; but is the effect of a
_
_
_
well—known seasonal variation.
A considerable increase took place in the captures of 1890,
seventy—nine hauls producing a total of 18,270 shes or an
average of 231 per haul.
Of these 14,953 or an average of 189
per haul were saleable, and 3317 or an average of 452 unsaleable.
The work giving this result was carried on during 10
months, ve of which were winter months, viz. February, March,
April, November and December, and ve warmer or productive
.
months, viz. May, July, August, September and October. While
the three rst
_
mentionedwinter months, however, produced
respectively 501, 720 and 891 shes of all kinds, the two last
months of the year gave respectively for seven hauls 1970 and
.
for nine hauls 1753 shes, a very considerable addition to the
;
totals.
The captures in the warmer months were as follow :—
May with 9 hauls' 1479, July with 7 hauls 2432, August With
6 hauls 2284, September with 5 hauls 2067, and October with
9 hauls 4173.
It is clear that if July, August and September
had had as many.hauls as October the result would have been
different, for these are productive
months.
In an inqu1ry
like the present, therefore,
it is important
to have the data
equivalent throughout, or at any
rate to be cautiousin drawing
_
deductions from results obtained under different conditlons.
