BIENNIAL REPORT
and confine my remarks to what may be deemed important, interesting
and to what should be printed for the information of those interested in
fish culture by the State of Wisconsin. I wish, however, to elaborate
somewhat on the subject of the conservation of fish and the necessary
restrictions in the taking, catching and killing of fish in our state.
  On the following pages will be found full and complete statistics covering
the output of our seven permanent hatcheries and three substations.
These tables give a complete statement as to the output of each hatchery,
varieties of fish hatched and planted, cost of operation, inventories, acre-
age, and value of lands, buildings and equipment.
                  HATCHERY IMPROVEMENTS.
  Since the issue of the last report by the former Commissioners of
Fisheries, the state established what may be called a "sub-station"
in
Tenney Park, Madison. This hatchery is operated only during the spring
hatching period, and is equipped forthe propagation of wall-eyed pike and
pickerel.
  An important improvement was made at the Bayfield Hatchery during
the past year. The conduit carrying the water from Birch Run pond to
the hatchery has been extended up through the pond so as to take the water
from the headwater springs. The extension is of twelve-inch vitrified pipe
and increases the length of the pipe line some 900 feet. By taking the
water directly at the springs we hope to remedy the following trouble.
In the spring when the young trout are in the hatchery troughs, the rains
and melting snow cause a heavy wash into Birch Run creek and pond.
These heavy spring floods are caused by the lands being cleared for culti-
vation in recent years. The timber and brush has been cut, the lands have
been plowed and each rain causes a heavy surface wash. The soil is a red
clay and the spring floods wash the soil into minute particles, carrying
it
into the pond in such great quantities that the water is turned a distinct
red. These clay particles are carried through the conduit into the fry
troughs, and the clay adheres to the gills of the little trout causing their
death by thousands. We expect to overcome this clay-water by taking
the water supply, as I stated above, from the head-water springs.
  It is the intention of the commission to build a number of fry ponds at
the head of Birch Run and in which we will hold and raise a great quantity
of our spring hatch of trout, until they attain the fingerling size, such
fish to be for fall planting.
  The barn at the Bayfield station was destroyed by fire on the afternoon
of September 22, 1916. The fire was caused by lightning. The loss of
the building and contents was approximately $1,500:00, which was covered
by state insurance.
  The Oshkosh Hatchery was moved from the former location in the North
Shore Park to a lot the commission purchased on the river bank. The
property has a 150 foot frontage on River street. The reason for the
change was because in the old location the hatchery was not giving satis-
factory results in the output of fry. This unsatisfactory condition was
caused by the water supply which did not afford the proper quality of
