While some Of us may depend
upon the position of the sun to de-
termine when spring has arrived
and others by the opening day OF
the baseball season. for the angler,
spring is here when the trout sea-
son is open.
This sport is participated in by
all classes from the President to the
farmer boy far removed from the
centers of population. AS the num-
Der of fishing poles has increased
rapidly, it has been necessary to in
crease the number of hatchery units
engaged in propagating fish to keep
our waters stocked with fish.
Forty-two of the states operate 359
hatcheries, representing an invest
ment of more than $500, 900 and
operating expenses of $2,645, 900,
with an annual output of game and
food fish and eggs approximating

report of the bureau Of fisheries.
Scheme Works Well
In addition, last year the federal
bureau Of fisheries operated seventy
seven stations and substations in
thirty-Six states, including the ter
ritory of Alaska and the District Of
Columbia. It also co-operated with
ia private organizations which
were interested in taking the tiny
fish from the bureaus hatcheries
and rearing them to a lingering size
before releasing them in their
streams to face the struggle for ex-
istence under natural conditions.
This cooperative arrangement is
working out very we'll, some OF the
co-operativeS claiming to have de-
veloped as good fishing as ever ex-
listed in their waters.
Of the ia c~ooperatives, "a are in
Wisconsin, 80 in Pennsylvania, Is in
Minnesota and 8 in New York. The
bureau supplied the co-operativeS
with more than 5000, 900 fish, mostly
trout.
Shipped to Foreign Lands
In addition, nearly $4,000, 900 fish
eggs were assigned to state and ter
ritoriaI fish commissions, and 3,000,-
600 trout and whitefish eggs were
shipped to foreign countries, includ-
ing Canada, Cuba, Japan, Peru and
Switzerland, and $50 small mouth
black bass fingerlings to Sweden.
The anglers interest lies chiefly
in two groups of fishes, first the
cold water species such as brook,
rainbow, Loeb Leven and black
spotted trout and grayling and land
locked salmon, and secondly In
warm-water species - the BASES,
sunf1shes, crappies and yellow perch.
The bureaus output of the cold
water game fishes exceeded 60,000,-
900 and of Warm-water species 20O,-
900, 900.
In recognition Of the Importance
of raising more fish to the lingering
size before releasing them in the ma
tural streams, the bureau was able
to increase it's output as compared
with the previous year by 27,760 900
fish or q per cent.
Conditions Favorable
Because of adequate rainfall in
the Mississippi valley which per-
mitted the river to recede slowly,
the necessity for rescue operations
was greatly curtailed, the output
amounting to 5000, 900 only in COM
parison with $50, 900 600 in normal
years.
A careful survey of conditions in
the upper Mississippi wild life and
fish refuge is being made to deter
mine the best methods of increasing
the natural productivity of these
waters of bass and other game fish.
The survey has revealed that the
fish trapped in the Sloughs through
the winter perish, revealing the need
for complete rescue operations.
Brood bass ponds have been &C
quired, the resulting fry to be used
for stocking the sloughs during the
summer months where the young
fish will find very favorable condi-
tions for growth and from which the
principal enemies of the young fish
have been excluded. BY such means
it is hoped greatly to augment the
supply of fish in which the anglers
