For waters where a population estimate has not been made, a regression model based upon population estimates from other waters will be used. The margin of safety used depends upon the age of the population estimate and whether a regression model was used.

NR 23.055 Modifications in daily bag limit and minimum size limit in response to tribal harvest. NR 23.055(1)(1)
Adjustment. I
n order to prevent a total harvest of more than 35% of the adult walleye population or 27% of the adult muskellunge population, the secretary may lower the daily bag limit on walleye or adjust size limits for walleye or muskellunge in specific waters in response to the harvest goals or actual harvest of the Chippewa Bands for their spear, net or trap fisheries. The adjusted daily bag and size limits shall be in effect until the first Sunday in March of the year following the tribal harvest. The safe harvest levels on individual waters shall be determined by the department.
NR 23.055(1)(a)
(a)
Walleyes. The daily bag limit may be reduced in response to harvest by the Chippewa Bands' spear, net, or trap fisheries. The extent of the reduction depends upon the percent of the safe harvest taken and the age of the population estimate used to determine the safe harvest or if a regression model was used to determine the safe harvest. The daily bag limits to be used with the different percentages and for various basis of determining the safe harvest are as follows:
-
See PDF for table NR 23.055(1)(b)
(b)
Muskellunge. The minimum size limit will be increased when the department is notified by the Chippewa bands that their
harvest goal on an individual water is 60% or more of the safe harvest. The minimum size limits to be used with different percentages of the safe harvest are as follows:
-
See PDF for table NR 23.055(2)
(2)
Readjustment. In response to actual tribal harvest, the secretary may raise the daily bag limit or reduce the minimum size limit to the limit specified as appropriate using the percent of the safe harvest level expected to be harvested as indicated in sub.
(1). If a new population estimate is made, the safe harvest level shall be changed accordingly and the daily bag limit or minimum size limit shall be adjusted according to the percentage of the new safe harvest level that is expected to be harvested as indicated in sub.
(1). The readjusted daily bag and size limits shall be in effect until the first Sunday in March of the year following the tribal harvest.
NR 23.055(3)(a)
(a) Reduced daily bag limits calculated pursuant to this section are individual lake limits and may be combined, but no person may exceed a total daily bag limit of 5 walleyes.

(b) While fishing no person may possess fish on any water in excess of the bag limit or under the size limit for that water.
