The scientific and common names used follow Bailey 
(1970). The families of fishes are arranged in phylo- 
genetic sequence, following the classification proposed by 
Greenwood et al. (1966). Within each family, however, 
genera and species are listed in alphabetical order. For 
each species a statement about its present distribution js 
given, and supplemental records and their sources are 
listed. 
Ichthyomyzon castaneus Girard—The chestnut lam- 
prey is occasionally taken from pool 20 downstream to 
the mouth of the Ohio River, but it is extremely sporadic, 
if still present at all, above pool 20. Supplemental rec- 
ords for pools 7-9 (UMRCC 1953) and 4, 5, 10, and 11 
(Nord 1967), but based on specimens collected almost 
20 years ago, are available. Starrett, Harth, & Smith 
(1960:342) noted that in Illinois the species no longer 
occurred as far north as its type-locality (Mississippi 
River, Galena, Illinois), but in Wisconsin recent records 
are available from the Fox and Yellow rivers (George 
C. Becker, personal communication, August 10, TORO 
Ichthyomyzon unicuspis Hubbs & Trautman.—The 
‘ilver lamprey is occasionally taken from pool 10 down- 
stream to the mouth of the Ohio River, but it is un- 
-ommon below the mouth of the Missouri River. Sup- 
olemental records are available for pools 5 and 7-9 
‘UMRCC 1953). Although our opinion is based on 
pecimens collected nearly 20 years ago, we believe the 
pecies still occurs above pool 10. 
Acipenser fulvescens Rafinesque.—The lake sturgeon 
$ Tare in the river. In 1966 an Illinois commercial 
isherman secured two specimens near Quincy that had 
| combined weight of 56 pounds, and a Missouri fisher- 
nan caught a 32-pound specimen near Elsberry. Supple- 
nental records are as follows: pools 4, 8-10 (UMRCC 
953), 3, 6, 17, 19, 20, and 22 (Nord 1967). 
Scaphirhynchus albus (Forbes & Richardson) .—The 
allid sturgeon is extremely rare. It is represented by 
small specimen given to Barnickol & Starrett (1951: 
90) in 1944 by a fisherman, who caught the fish near 
1e mouth of the Missouri River (the type-locality) , and 
small specimen secured at river mile 75 in the spring 
f 1970. A record for Keokuk (Coker 1930) is not 
ccepted because it is quite old. There is no other 
vidence of the occurrence of the pallid sturgeon in 
le Mississippi above the mouth of the Missouri River. 
Scaphirhynchus platorynchus (Rafinesque). — The 
lovelnose sturgeon is taken occasionally from Lake Pepin 
) the mouth of the Ohio River. Supplemental records 
€ as follows: pools 4 (UMRCC 1965) , 5-6 (UMRCC 
68) , 7-9, 12, 14, 18-20, 25, 26 (UMRCC 1955), 10, 
L, 13, and 15 (UMRCC 1960): 
Polyodon spathula (Walbaum).—The paddlefish is 
ken occasionally from pool 9 downstream to the mouth 
the Ohio but is rare in the upper pools. Supplemental 
cords exist for pools 4, 5 (UMRCC 1953), 6, 8 (Nord 
67), 9 (UMRCC 1958), 10-15, 17-20, 22, 24 (UM 
CC 1961), 25, 26 (UMRCC 1963), and B-26 (Bar- 
ckol & Starrett 1951). 
Lepisosteus osseus (Linnaeus) —The longnose gar is 
nerally distributed and seemingly more common above 
an below the mouth of the Missouri River. Supple- 
ental records are as follows: pools 3-5 (UMRCC 
5 
1964), 8-10 (UMRCG £953) 5o1 1 yell 6a 7,519) 24, 
and B-26 (Barnickol & Starrett Lob lan 
Le pisosteus platostomus Rafinesque.—The shortnose 
gar is widely distributed and especially abundant below 
the mouth of the Missouri River. Supplemental rec- 
ords are available for pools 2-5 (UMRCC 1964), 6, 8, 
9 (UMRCC 1953), 7 (UMRCC 1958), 11, 12, 14, 15, 
25 (Barnickol & Starrett 1951), 16, and 17 (Starrett 
& Barnickol unpublished). 
Lepisosteus spatula Lacépéde.—The alligator gar is 
rare. In addition to the published records of Barnickol 
& Starrett (1951), photographs of a 130-pound speci- 
men from Cairo and a 110-pound specimen from Chester, 
both caught by Illinois commercial fishermen in 1965, 
are available through the kindness of Mr. O. M. Price 
of the Illinois Department of Conservation. 
Amia calva Linnaeus—The bowfin js widely dis- 
tributed and seemingly more common in the impounded 
pools above the mouth of the Missouri River than be- 
low. Supplemental records are as follows: pools 3-6, ‘by 
26 (UMRCC 1963), 7, 8, 22 (UMRCC 1961), 9, 10,

rett 1951), and 21 (UMRCC 1965). 
Anguilla rostrata (Lesueur) —The American eel is 
occasionally taken from Lake Pepin to the mouth of the 
Ohio River. Supplemental records are available for pools

Alosa alabamae Jordan & Evermann.—The Alabama 
shad is extremely rare and is represented by one small 
specimen taken in 1962 in a seine haul at river mile bo2: 
An old record for Keokuk, reported as A. ohiensis by 
Coker (1930), has not been plotted. 
Alosa chrysochloris (Rafinesque) .—The skipjack her- 
ring is moderately common near the mouth of the Ohio 
River and occasional as far upstream as pool 15. Sup- 
plemental records are: pools 13 (UMRCC 1958), 16, 17 
(Nord 1967), and 20, 21 (Barnickol & Starrett 105 1N 
Other early published records are not plotted. 
Dorosoma ce pedianum (Lesueur) —The gizzard shad 
is abundant throughout the river. There is a supple- 
mental record for pool 2 (UMRCC 1965). 
Dorosoma_petenense (Ginther).— The threadfin 
shad is moderately common near the mouth of the Ohio 
River. 
Hiodon alosoides (Rafinesque) —The goldeye is com- 
mon from pool 20 downstream to the mouth of the Ohio 
and especially common below the mouth of the Missouri 
River. Supplemental records are as follows: pools 3, 4,

Hiodon tergisus Lesueur.—The mooneye is widely 
distributed but is much more common above pool 20 in 
less turbid pools than it is below pool 20. Supplemental 
records exist for pools 3-5 (UMRCC 1964), 6-11 
(UMRCC 1953), 14, 15 (Barnickol & Starrett TOS Vie
