a Measurements to be from end of nose to fork of tail. Limits on sale only, and do not apply to minnows 
used for bait. Limits given by weight are as follows: Blue or channel catfish and drum, 2 pounds; carp 
and buffalofish, 3 pounds. 
b Fish measurements are taken for “‘the length of the entire fish from the extreme tip of the snout to the 
extreme end of the tail fin,’ and turtle and terrapin for the extreme ends of the upper shell. Restrictions 
do not apply to pole and line fishing. The limit on lake trout and whitefish is 1; pounds, dressed. The 
catfish restriction is confined to “blue and channel catfish.” 
c Section 2542 and ch. 42 of 1917. The size limit on trout does not apply to boundary waters. 
dA different size limit (in interstate waters) is set for the species of sturgeon, being 1 pound for the sand 
sturgeon, shovel-nose sturgeon, or hackleback Se an ela platorhynchus (Rafinesque), and 3 pounds 
for the rock sturgeon or lake sturgeon Acipenser rubicundus Le Sueur; the former would perhaps include 
the white sturgeon Horbaceplisig acts albus Forbes and Richardson. The restrictions as to interstate 
waters do not apply to hook and line or spear fishing. 
ane bereapia restriction is only on the diamond-back. Size limits for salt-water species are fixed by 
other acts. 
f Sections 4827 and 4873 and ch. 471 of 1917. Measurements are taken from tip of snout to fork of tail; a 
different size limit is set for the two species of pike perch, being 14 inches, or 1 pound dressed, for the wall- 
eye, and 10 inches for the sauger. The limit on lake trout and salmon from inland waters is 16 inches. 
Catfish under 15 inches tip to tip rough, or 12 inches dressed, shall not be taken in nets in interstate waters. 
The limits for international waters are: Sturgeon, 15 pounds dressed; lake trout, 2 pounds round, or un- 
dressed, and 1} pounds dressed; whitefish, 16 inches; wall-eye, 14 inches, or 1 pound round; muskellunge, 
30 inches; sauger, 10 inches. The language of the statute is not perfectly clear, but these restrictions seem 
to be limited to international waters. Mussels, except “pigtoes,’’ shall not be taken smaller than 1} inches. 
9 Measurements are taken from end of nose to fork of tail. The restrictions are applicable only to fish 
sold. The catfish restriction is limited to ‘blue and channel catfish.” 
h Measurements are made from end of nose to longest tip of tail (1449). Restrictions on striped bass, 
buffalofish, bullhead, carp, catfish, “‘pike,”’ yellow perch, sturgeon, and whitefish apply only to com- 
mercial fishing in the Lake Erie dis rict, and even here it is jawiul to retain 3 per cent, by weight, of under- 
sized fish, or 10 per cent of ‘‘pike’’; the whitefish limit is 1? pounds. Catfish and sturgeon shall not be 
brought ashore in such condition that the length can not be measured. 
iThe limit on sturgeon applies only to boundary lakes (1913, act 71, sec. 10). 
j Measurements are taken from end of snout to center of fork of tail. 
k Measurements are taken from tip of snout to tip of tail. The restrictions as to Great Lakes fish limit 
only licensees in those waters; any such licensee taking undersized fish shall bring them ashore and notily
