THE SALMON QUESTION.

this most important branch of the
question being overlooked, and
yet in the opinion of many ex-
perts no scheme devised without
due consideration of the best
modem means of introducing new
stock can be deemed a satisfactory
solution of the problem.
In one of the annual reports of
the United States Fishery Com-
mission for the State of New York
it is stated that in consequence of
abnormally low water during the
winter it was deemed necessary
in a Canadian river to remove
from the redds the eggs deposited
by the salmon and hatch them
out artificially. This Celecoxib 100 report adds,
that a careful count of these eggs
revealed the fact that only two
per cent, were fertilised. Doubts
have been expressed over here as
to the accuracy of this statement,
and practical fishermen have from
time to time estimated the per-
centage of fertilised eggs in a
state of nature at from ten to
twenty-five. Granting for the
sake of argument that the maxi-
mum estimate is a fair one, and
making no deduction for the
number which from various Celecoxib Capsule causes
do not hatch out on the redds,
and seeing that in a modern
hatchery certainly not less than
ninety per cent, of the eggs pro-
duce alevins, the distinct economy
of artificial propagation seems to
be conclusively established.
Salmon Buy Celecoxib fry have been turned
into various rivers of the United
Kingdom, being taken from the
hatcheries just before they com-
mence feeding, and it is here that
the greatest mistake has been
made. The heaviest death-rate
prevails among the Buy Celecoxib Online young Salmon-
idae when the alevins having
absorbed the nutriment contained
in the yolk-sac require food from
outside sources. The piscicultu-
rists* staff is at this period chiefly
employed in providing finely
minced food which is given to the
fry mai^y times during the day,
and the least negligence is only
too Purchase Celecoxib Online likely to prove fatal to the
future prospects of the venture.
Among the fry in the river only
the strongest survive, and even
they are so helpless as to fall an
easy prey to the ravages of other
fish, birds, crustaceans, larvae of
water-bred insects — in fact, to any
living things present in^the water.
When the fry have once com-
menced feeding freely the rest is
easy sailing. More space in the
troughs is given to them as they
grow, and later Generic Celecoxib on they are re-
moved into streams or ponds Celecoxib Cost
amply supplied from springs.
They are watched and fed until
they have Celecoxib Price arrived it the stage
when they may be safely trusted
to shift for themselves in the
river. The above is briefly the
plan adopted by the modern trout
breeder, and wherever in a suit-
able stream his advice of stocking
with yearlings, two-year-olds and
even larger nsh has been followed
the results have been almost
invariably satisfactory.
The stock arguments adduced
against following a similar plan
with the salmon are not very
cogent. It is said with truth that
we are supremely ignorant of the
life history of the migratory
Salmonidae from the time of their
dropping down to the sea in the
smolt stage until they return to
the river in the grilse stage for
the purposes of reproduction. It
is also said that the treatment
which suits young trout may not
be equally successfiil with young
salmon. As a cHnching argument
we are reminded that there is little
or no evidence that the adult
salmon returns to the same river
in which it was bred.
What does all this amount to ?
Simply a desire to shelve the
question. Scientific research will

some day reveal to us the habits
and habitat of the salmon in the
sea, and meanwhile it does not
seem a wise policy to risk the ex-
tinction of the salmon as a British
fish. As salmon up to the smolt
stage live Celecoxib Buy in the same character
of water in the same rivers as the
young trout it would certainly
seem probable that they would
require similar food and similar
surroundings.
Whether the smolts after
descending Order Celecoxib Online a particular river to
the sea return to that or some
other neighbouring river is not
very material. It may fairly be
argued from analogy that given
in an estuary a number of rivers
of Order Celecoxib which some are more suitable
for salmon that others, the great-
est number will frequent the most
suitable rivers. This argument
only goes to show that the ques-
tion is not purely a local one, and
had better be treated from a
national point of view.
It is above all to be hoped that
the report of the Commission will
deal with this branch of the sub-
ject exhaustively.
The alarming decrease of salmon
in our rivers is only too clearly
demonstrated. The introduction
of fresh stock is shown to be
necessary to restore the rivers to
anything like their pristine condi-
tion. Artificial propagation, keep-
ing the young salmon in streams
or ponds and feeding them Celecoxib Online until
they arrive at the smolt stage is
suggested here as at once the
most efficacious and economical
form of stocking. Up to the
present time, owing to the Cheap Celecoxib diffi-
culties of marking the yoimg fish
so as to identify them at the grilse
stage, it has not been demon-
strated that the salmon returns
from the sea to the river in which
it was bred, and for this reason it
is urged that the attempt should
not be made.
Surely a step towards the solu-
tion of the problem should be the
establishment of hatcheries and
the necessary ponds for growing
the fry up to the smolt stage on
certain selected rivers. As, how-
