The 1885 figures are still materially
below the maximum output OF several
years ago, which exceeded 100000.
000 To considerable extent, the in
crease in the past year was due to the
resumption of the activities at the
Gloucester (Mass.) Station, which
propagates marine forms. Coupled
with its increase. there was slight

varieties, both game and commercial.
handled at interior stations.
Increase in Marine Forms.
An increase of approximately l,400.-
000, 900 in the output Of cod, paddock,
pollock and Winter founder was noted
by the bureau. However, the bureau
points out, a large percentage of this
increase Is represented by eggs fertil-
lied on the fishing boats and planted
on the spawning grounds. since funds
were not available for full-scale oper-
alton of the hatchery. The output OF
these marine forms represents between
IS and 80 per cent of the total output.
a ratio which is similar to the average
over a number of years.
While increases were registered for
the output of silver and chum salmon,
the bureau says. there was q slight de-
cline In the production Of sockeye sal
mon. This was due to negligible egg
collections at the Quinault tWash)
Station, ordinarily the biggest pro-
ducer of sockeyes since closure OF the
Alaska stations. The run Of fish did
not materialize. presumably on &C.
count Of everlasting In previous years.
Shad Remains the Same.
The production Of shad was virtual
ly the same as in 1884. An output OF
$50 900 Atlantic salmon in Maine was
significantly larger than in the pre-
vious year when Canadian eggs were
not obtainable. Land-locked salmon
were produced in lesser numbers. An
increase in output of yellow perch to
$50 100000 was derived from resump-
ton of this activity at the Potomac
River station at Fort Belvoir, Va.
Observing the state Of the supply Of
shore fish in the Middle Atlantic
States. the bureau says conservation
must be promoted by regulating the
strain of exploitation from Chesapeake
Bay southwark, rather than by drastic
restriction of the catch in Northern
waters.
Fully one-half Of the total supply Of
squeteague, soup, sea bass. founders
and minor species taken north Of the
Delaware Bay Is derived from spawn
ing in Southern waters.
Wastage in Southern Waters.
Regulation Of the New Jersey shore
fishery Is complicated by the rapid
development Of the off-shore trawl
fishery in Virginia, the bureau points

branch Of the fishing industry has
been shown to depend not only on the
abundance of fish. but ON the degree
Of availability which Is affected by
changes in water temperatures. Vast
age Of immature fish In Southern wa
tiers constitutes q heavy drain upon
the supply. Depletion has not yet been
demonstrated. although its possibility
as result Of severe exploitation In
the shore areas In the Summer and
the off-shore areas in the Winter is
clearly recognized, the bureau states.
The value of the Bureau of Fisheries
investigation in the field Of fishery
waste utilization has been very APP
parent during the past year. Studies
with respect to the utilization Of SAL
mon cannery waste have demonstrated
that valuable Ntamin-active oils and
high quality edible oil can be re-
covered from this type Of material by
proper methods Of preparation.
