Relative growth of fins in the fourhorn sculpin, Myoxocephalus quadricornis, from the upper Great Lakes Relative growth of fins in the fourhorn sculpin, Myoxocephalus quadricornis, from the upper Great Lakes
Livers of 445 wild bobwhites taken in Iowa, Wisconsin, and Illinois in late fall and winter of 1947-48 were assayed for vitamin A. All contained vitamin A; but the amount in many was so low that it is estimated that 4% of the birds would have died directly from lack of vitamin A within 3 weeks or that as much as 42% might have been affected enough to make them die from predation and...

Environmental changes in Lake Erie Environmental changes in Lake Erie
Comparison of data compiled during the past 60 years with those from recent studies shows that major changes have occurred in the bottom and fish faunas of Lake Erie. The bottom fauna was formerly dominated by the nymphs of Hexagenia, but at present midge larvae and oligochaetes are most abundant. Blue pike (Stizostedion vitreum glaucum) and cisco (Coregonus artedii), which formerly...

Downstream movement of lampreys and fish in the Carp Lake River, Michigan Downstream movement of lampreys and fish in the Carp Lake River, Michigan
An inclined-screen trap was installed on the Carp River, Emmett County, Michigan, in the spring of 1948 and has been in almost continuous operation since that time. The major goal of this project--a precise determination of the length of the larval life of sea lamprey--was not attained because of the contamination of the stream above the dam with spawning lampreys. The lampreys and other...

Use of 3-trifluormethyl-4-nitrophenol as a selective sea lamprey larvicide Use of 3-trifluormethyl-4-nitrophenol as a selective sea lamprey larvicide
The recent discovery of a group of chemical compounds that are significantly more toxic to sea lampreys than to other aquatic organisms offers promise of an early and effective control of this pest. The sea lamprey has all but destroyed the lake trout populations of Lakes Huron and Michigan. In Lake Superior, production of the lake trout fishery has declined to record low levels. Only a...

Records, ages, and growth of the mooneye, Hiodon tergisus, of the Great Lakes Records, ages, and growth of the mooneye, Hiodon tergisus, of the Great Lakes
Mooneyes (Hiodon tergisus) are very scarce in the upper three Great Lakes since only four specimens have been received from Lake Michigan, one from Lake Huron, and none from Lake Superior. The published statistics of the mooneyes are erroneous. Those of 1931 of Lake Michigan were perhaps chubs (Coregonus spp.) and those of Lake Huron of 1929 were also chubs and of 1934, 1949, and 1951...

Recent changes in the walleye fishery of northern Green Bay and history of the 1943 year class Recent changes in the walleye fishery of northern Green Bay and history of the 1943 year class
Production, fishing intensity, and availability of walleyes (Stizostedion vitreum vitreum) fluctuated widely in the commercial fishery of northern Green Bay in 1929-57. The catch ranged from 16,000 pounds (8 percent of average for the 1929-53 base period) in 1942 to 1,294,000 pounds (633 percent) in 1950. The index of fishing intensity ranged from 17 (1941) to 400 (1950) and that of...
