BULLETIN OF THE UNITED STATES FISH COMMISSION, 
PENNAMAQUAN EIVER. 
Near the lake, Pemiamaqiian Elver is shallow, rocky, and rapid. Farther down 
it is more slug’gisli and boggy for the remainder of its course, and abounds in the 
common fresh water plants. It has three milldams: one at Pembroke village, another 
about a half mile above, and a third about 3 miles np. The last we did not have the 
opportunity of examining. Salt water makes its way nearly np to the lower dam. 
No artiticial lishways have been constructed, but when the water is sufficiently 
high fish can pass through some rude excavations in the rocks at the ends of the 
dams, 
Alewives are said, at one time, to have run up the river in abundance, but 
since then the numbers have greatly diminished. Many young ones, however, were 
seen coming down this season. Pickerel up to 3 pounds in weight are reported to be 
common, 
A small brook enters at Pembroke, i]i which trout are said to be caught, as well 
as in the brackish water at its mouth. On October 0 several hauls of the 25-foot 
seine were made in the river for about 14 miles above the second dam. The common 
water plants, such as cat-tails, lily pads, pickerel weed, etc., were abundant, though 
dead at this time. Spiders, water bugs, insect larvne, and snails were exceedingly 
numerous among the grass and weeds. 
The temperature of the water was 62*5° F. 
The fish taken were Notemigonus chrijsoleucus, very common; IaicIhs reticulatus, 
common; Lepomis gibbosus, common; Perea Jiavescens, common. 
The abundant fresh- water plants, muddy bottoms, coves, and lagoons supplied 
with x)ickerel weed and water lilies, afford an ideal home for pickerel. 
Boyden and Peunamaciuan lakes also seem more suited, in their general charac- 
teristics, to such fishes as pickerel, chubs, suckers, and horupouts, than to trout, 
salmon, or other species of like habits. 
List of Fishes obtained in Boyden Lake and Pennamaquan Lake and Biver. 
Ameiuriis nebulosits (Le Snear). “Hornpoiit.” 
Catostoinus teres (Mitcliill). “Sucker.” 
Notropis meyaiops (Eafiuesqne). “Eed-fiimed 
Minnow.” 
Semotilus buUaris (Eatinesque). “ Chub.” 
Noternigonusclirysoleucus (Mitchill). “Shiner.” 
Clupea asHvaUs Mitchill. “Alewife.” * 
Osmerus mordax (Mitchill). “Smelt.” 
Funduhis diaqihanus (Le Sueur). “Fresh-water 
Minnow.” 
Lucius retieulatus (Le Sueur). “Pickerel.” 
Anguilla ehrysypa Eafinesque. “ Eel.” 
Lepomis gibbosus (Linnaeus). “Sunhsh.” 
jilicropterus dolojnieu Ijiicepede. “Black Bass.” 
Perea jiavescens (Mitchill). “ Yellow Perch.” 
* The specimens appear to be the young of Clupea cesiiralis, agreeing with this species in the black 
peritoneum. In the somewhat larger eye and slightly higher dorsal tin, they differ, however, from 
the usual aspect of C. cestivalis and approach Clupea pseudoharengus.
