BIENNIAL REPORT
Michigan, Lake Superior or Green Bay, or within one-fourth mile of the
shore hne of Door county, or in any of the harbors or bays of Door county.
  3. An absolute closed season in Lake Superior during the period from
September 15 to November 1, and in Lake Michigan and Green Bay
during the period from October 20 to December 1.
  4. Stipulate the minimum size of lake trout, whitefish, chub, herring,
bluefin, pike, pickerel and other fish that may be caught, had in possession
or under control.
  The statistics on Lake Michigan and Green Bay show that last year the
state licensed the use of 12,533,665 feet or 2,375 miles of gill nets. Do
you
realize this means that if the licensed gill nets were joined they would
reach from New York to Chicago, to St. Paul and then down to the City
of New Orleans? Over two million set hooks were used. It is said that
a man cannot count a million dollars, one at a time, in a life time. This
will give you some understanding as to the dire necessity of placing upon
the Statutes of Wisconsin, fishing laws that are truly in the light of con-
servation, laws that should be simple, each to understand, laws that may
be enforced and laws that, when violated, the violater may be brought
into court and the state be able to secure a conviction.
                     DISTRIBUTION OF FISH.
  A great majority of the people interested in the planting of fish are of
the opinion that because the fish hatchery is located in their midst, noth-
ing further is necessary to furnish fry for distribution. They do not under-
stand that we must either have a large number of breeding fish on hand,
or that we must catch a large number of mature fish during the spawning
season to obtain eggs for hatching. Brook and rainbow trout and black
bass are the only varieties of fish that we raise for propagation purposes,
and keep in our ponds, from which to obtain eggs for the hatchery.
  At the time we started the 1916 distribution of fry, our files contained
approximately 17,000 applications for fish of the various varieties. These
applications were received from every part of the state. All told, ap-
proximately 206,000,000 fry were planted in the waters of Wisconsin by
this Department. Of this number, some 140,000,000 brook and rainbow
trout, pickerel, pike and muskellunge were planted in inland waters. The
remaining 66,000,000 consisted of lake trout, whitefish, bluefin and chub,
which were planted in the outlying waters of the Great Lakes and Green
Bay.
  The following table will show how the eggs of the different species of
fish vary in size. We use as a basis the number of eggs per quart.
    Brook trout average .  .............. . 13,000 to the qutrt
    Rainbow. trout average ...............  10,000 to the quart
    Lake trout average               ..............7,000 to the quart
    Wall-eyed pike average       .............. 150,000 to the quart
    W hitefish  average .................................. .........  40,000

    Muskellunge average          ............... 50,000 to the quart
    Bluefin average.  .     ........................... 120,000 to the quart
  The prevailing color of fish eggs in healthy condition is of an amber hue.
If the eggs have not been properly fertilized or if there has been an undue
