Progress report on the sea lamprey study
SUMMARY: The Peromyscus leucopus on a 17-acre study area were live-trapped, marked, and released over a seven-day period. On the three following nights intensive snap-trapping was done on the central acre of the study plot. The animals caught by snap traps in the central acre represented the population of the central acre and several surrounding acres. By the currently accepted methods of

A definition of depletion of fish stocks
Attention was focused on the need of a common and better understanding of the term depletion as applied to the fisheries in order to eliminate if possible the existing inexactness of thought on the subject. Depletion has been confused at various times with at least ten different ideas associated with it but which, as has has heen pointed out, are not synonymous at all. In defining depletion we mus

Age and growth of the lake whitefish, Coregonus clupeaformis (Mitchill), in Lake Erie
Although the whitefish has by no means ranked first from the standpoint of production, it has always been an important commercial species in Lake Erie. Trends in the output of whitefish have differed in the United States and Canadian waters of the lake. The 1893–1946 average annual yield of 1,201,000 pounds in the United States was only 38.3 percent of the 1879–1890 mean of 3,133,000 pounds, where

The present status of the United States commercial fisheries of the Great Lakes
This review of the trends in production on the Great Lakes suggests that great biological changes have taken place. The general abundance of the choicer varieties, and of some of the less choice fishes, has been lowered considerably; and the prospects are that this level will fall still farther. In addition, the niches occupied by these finer species in the lakes have not been filled by coarser

The age, growth, and distribution of the longjaw cisco, Leucichthys alpenae Koelz, in Lake Michigan
The longjaw (Leucichthys alpenae) was found at all of the 109 stations fished in the open lake during 1930–1932 and at 29 of the 32 stations in Green Bay in 1930 and 1932. Koelz (1929) found the longjaw at 35 localities, 33 of which were different from those fished in 1930–1932. The species was most abundant in water with a depth of less than 70 fathoms, but was found as deep as 97 fathoms. The lo
