except salmon, bass, shad, and trout may be taken for bait or scientific purposes 
by means of hand or cast nets (42). The only tackle permitted is hook and line 
and trot line having hooks not less than 2 feet apart, and hand or cast nets to take min- 
nows for bait; other tackle may be used by the owner to take fish from private springs 
or ponds, and persons other than the owner shall not take fish from such waters (42). 
Drugs, explosives, and electricity shall not be used to take fish (46, 47). Fishing on 
lands of another person without permission is forbidden (48).

hearing, in what manner, in what numbers, in what places, and at what time wild 
animals (includes fish) may be taken (29.21). : 
Closed seasons (omitting provisions for special counties or bodies of water) are as 
follows, all dates being inclusive: Black bass from March 2 to June 14; “Oswego 
bass, green bass, and yellow bass,’’ from March 2 to May 28 (as these names are popular 
synonyms for black bass it is impossible to know certainly what the closed season is, 
in this State, for black bass); yellow perch and sunfish in counties bordering on the 
Mississippi River, and rock bass, white bass, catfish, muskellunge, pike perch, and 
pickerel in the State generally, from March 2 to May 28; trout, from September 1 to

Bag limits are 10 black bass, 30 rock bass, 35 trout, 10 pike perch, 15 pickerel, 2 
ee 10 catfish, but no catfish limit on Mississippi River, 30 pounds of bull- 
head (29.19). 
All fishing is prohibited in streams and creeks containing trout, during the close 
season for trout; or at any time in any spring hole or artificial well connected with 
any of the waters of the State; or by means of shutting or drawing off water for that 
purpose; or within 200 feet (more in some localities) of any fishway, lock, or dam 
except with hook and line (29.26). 
Not more than three lines may be used, each having not more than two hooks or

use of snag line or snag pole is prohibited (29.27). 
Fishing through ice is prohibited in certain waters; spearing of pickerel through 
the ice is permitted in the Mississippi River and its lakes, bays, bayous, and sloughs; 
fish shelters may be used on the Mississippi River and certain other waters (29.28). 
Explosives, poisonous substances, and other substances deleterious to fish life, or 
which might attract fish in unusual numbers shall not be used for taking fish, except 
that cisco may be baited with oatmeal for the purpose of catching them with hook 
and line through the ice (29.29). 
Minnow seines not over 40 feet long (100 feet in Great Lakes waters) and 5 feet 
deep, and dip nets not exceeding 6 feet in diameter, may be used for taking rough 
fish minnows for bait; but in trout streams they must be used only under the super- 
vision of a deputy warden (29.32). 
Net and set-line fishing is regulated as follows: No apron or other device to catch 
small fish shall be used in pound net; no net shall shut off more than one-half the 
channel or passageway of any stream, or be set within 1,000 feet of any other net; no 
licensee shall join his net to that of any other licensee; flags bearing the license 
number must be maintained over nets and lines; licensees in Great Lakes waters 
must permit State officials to accompany them and the officials may at any time 
raise set lines; except in specified Great Lakes waters, no net shall be drawn or lifted 
from one hour after sunset until sunrise; all rough fish taken in nets in inland waters 
shall be brought to shore and disposed of, but not returned to the water; sizes of nets 
specified mean the size, stretch measure, at the time of use (29.30). 
Set lines may be used in certain waters with hooks not smaller than 5-0, and with

Elaborate and complicated regulations are provided for net and set-line fishing in
