INVESTIGATIONS IN sr ANDREWS BAY, 1884.
and the average catch by this 'net is improved in darkness, the =“
commercial ships had an advantage. The returns of the
“ Garland,” therefore, from the beginning have to be considered”
to some extent on their own merits.
Instead of continuing the 5
work of 1884, extending it, and lling in gaps, new experiences,
of less moment in the question, were created, and the come :
parison
results rendered more complicated.
:
lu 1884 the four hauls by the poWerful trawl‘ers from:
:
Granton took place in January and May, and as subsequent
_
experience in the “ Garland” showed, these two months were
'
not characterised by very high averages.
They yielded 2,521:
saleable shes, composed early in January of 402
6 large cod, 343 plaice, 245 whitings, and 18 dabs, besides other
forms in small numbers such as thornbacks (which are absentî
_
from the returns of the “ Garland”), About a fortnight
.
in the same month, the saleable round shes were still moreÎ
abundant, Viz. 98 large haddocks, 639 small haddoCks, 122
whitings, 77 plaice, besides cod, turbot, brill, grey skate, thom—
back, and long—.rough’dànbs. The other two hauls were
on
the lst and 2nd of May in daylight, and it is interesting
to observe the change that had occurred in the sh-fauna_
Taking the two hauls together for -brevity, it is found that the:
