Evolution and distribution of the coregonids
Increased knowledge of the morphological and physiological plasticity of the coregonids has minimized the significance of conflicting morphological data that have retarded the development of an evolutionary theory. Of the four phyletic lines recognized through worldwide studies,Coregonus originated in the lake and stream area of northwest Eurasia, Stenodus andProsopium evolved in the rivers of Sib

The control of the upstream movement of fish with pulsated direct current
Alternating-current electromechanical devices installed in the mouths of streams have proved effective in stopping the spawning migrations of the parasitic sea lamprey (Petromyzon marinus) which has seriously damaged Great Lakes fisheries. In a few streams, excessive mortality has occurred to other fish at the alternating-current barriers. A direct-current unit was developed in an attempt to reduc

Structure and growth of scales of yellow perch of Green Bay
The appearance of the scales of yellow perch differs with the location on the fish's body. Comparison of scales of Green Bay perch taken above and below the lateral line reveals the former to have more sharply defined circuli and to exhibit fewer false annuli and less of the shading that impedes accurate assessment of age.
Estimates of age from modes in length-frequency distributions and from scal

Recent changes in the deep-water fish populations of Lake Michigan
The deep-water fish fauna of Lake Michigan consisted of lake trout (Salvelinus namaycush), burbot (Lota lota maculosa), seven species of chubs or deep-water ciscoes (Leucichthys spp.), and the deep-water sculpin (Myoxocephalus quadricornis). Other species occupied the deep-water zone but were not typically part of the fauna.
Lake trout, burbot, and a well established commercial fishery held the ch

The near extinction of lake trout in Lake Michigan
After the collapse of the commercial fishery for lake trout (Salvelinus namaycush) in Lake Michigan in the late 1940's, the further decline of the population was traced by records of numbers of small lake trout (mostly 11 to 16 inches in total length and 3 to 5 years old) caught in small-mesh nets of the chub (Coregonus \[= Leucichthys\] spp.) fishery. By 1951 the estimated abundance of these lake

History of Red Lakes fishery, 1917-38, with observations on population status
A historical account traces the development of the commercial fisheries of the Red Lakes, Minnesota, from its inception in 1917 as a war measure through 1938. The trends of production and catch per unit of effort were followed for the principal species with notes on statistics of the minor fishes. Life history data were recorded for the walleye and yellow perch. A historical account was present

H-bomb in the garden patch
Effect of newer insecticides on survival and reproduction of birds, especially quail and pheasants. According to author (who disclaims responsibility for title of paper), material here is essentially the same as that presented by him in Atlantic Naturalist 11(3), 1956 and Agr. & Food Chem. 4(10), 1956.
