MODEM FISH CULTURE.


Great Descovsry Recently Made BY Fran
co.'s Lugrin. Of Geneva.
For y number Of years past the
Swiss Government and several private
firms and individuals have made de-
ternined efforts TO rcssock the OK.
hausted lakes md streams Of Switzer-
land. Until quite lately III these
efforts proved practically abortiye.
But recently NJ. Francois Lugrin. Of
Geneva, invented . highly successful
process for propagating in large guam
titles and at nominal cost various
species OF minute crabs. etc, upon
which the young fry OF various fish
feed during the first few months Of
their lives. This new means of BUS
tanning the young fish upon natural
food until they attain sufficient size
and strength to make their way sue
cessfulIy in open water has solved the
hitherto most serious obstacle in fish
culture. Hitherto all such attempts
have had only negative result: at all
events. 1t is impossible to cite a single
case of success. Tens and hundreds
Of thousands OF small fry have been
Matched and turned into the waters of
Geneva, among which were several
species which it was hoped to acclima-
tie, but never fish OF these species
has been caught or seen. Notable
success, however, has been achieved
by the system Of Messrs. Lugrin and
Du Roveray.. who own and manage the
piscicultural establishment at Gremaz.
in the French Department Of Ain.
Near the end OF December, 1886.
Messrs Lugrin and Du Roveray, as
we learn from the American Consul at
Marseilles, received from this country
six thousand eggs of species of sal
mon which was unknown in Europe
until artificially propagated there.
The eggs in question were duly
Matched, and the young fish kept in
the tanks at Gremaz. fattening upon
the abundant living food provided by
the Lugrin process, until the oath
of April, at which time five Thousand
Of them were put into the lake Of
Annecy, beautiful sheet of water in
the department OF Haute Sayoie. At
this time these robust young fish had
attained an average length Of LILO
inches, and weighed about / ounces
each. On the LIST of September, one
hundred and thirty days after Being
thus planted, two of these fish were
caught at different points of the lake,
and were officially weighed and
measured. Each had attained length
Of 81 inches, and weighed Al ounces.
They had thus trebled in weight. and
nearly doubled in length, in little
more than four months. Many other
specimens of the same brood have
tebeen taken in the nets of the fishermen
of Annecy, but they are, OF course,
liberated, it being rigidly forbidden to
interfere with the final result OF an
experiment which has begun so
promisingly.
Commenting. upon these facts, the
Swiss journals regard the problem OF
restocking their depleted @waters as
substantially solved. and Mr.. Lugrin
has received from official sources
many fattering congratulations.
The fatal difficulty hitherto has been
that, owing tostheabseaee of Unavailable
food and the intense cold of the Swiss
lakes and rivers, most of which are
fed from glaciers, the tender young
fish which have been turned into the
water few weeks after Matching,
have persisted from cold, hunger and
other accidents, whereas the robust
and vigorous yearlings, already old
enough to catch living food and fight
their way, have striven with the ex-
traordinary results above stated, It
is estimated that a thousand WELL
grown and healthy yearlings are OF
more value for stocking open waters
than a million of the delicate creatures
Of the tender age at which they have
been hitherto planted, for want of
means-to properly feed them when in
confinement. IN. Y. Ledger.
