Disease prevention in the trout hatchery
With the comparatively recent evolution of fish hatching into true fish culture the problems offered by fish disease have likewise evolved from more or less of a petty annoyance into a first class headache.

Treat - think - and be wary, for tomorrow they may die
For some very strange reason it is easy to minimize the villian's role, played by disease-producing organisms, in the theater of modern fish culture. Much concern is felt over the food bills footed each month by the hatcheries, but very little is thought about the dead fish which are picked from the hatchery troughs during the same period.

Michigan's commercial fisheries of the Great Lakes
Five races of cottontail rabbits belonging to three species occur in Virginia. One of them, the Mearns cottontail (Sylvilagus floridanus mearnsi), is reported here for the first time. It occurs in six southwestern counties of the state, while the eastern cottontail (S. f. mallurus) occurs in the remainder of the state with the exception of Smith and Fishermans islands off the eastern coast of Cap

The food of the lake trout (Cristivomer namaycush namaycush) and of the lawyer (Lota maculosa) of Lake Michigan
This paper reports on a qualitative and quantitative analysis of the contents of 4,979 lake trout stomachs (593 examined in 1930 and 1,253 collected in 1931 from southern Lake Michigan, 1,446 from northern Lake Michigan and 1,687 from Green Bay in 1932), and of a total of 1,528 lawyer stomachs (172 examined in 1930 and 734 collected in 1931 from southern Lake Michigan, 612 from northern Lake Michi

Morphometry of the cisco, Leucichthys artedi (Le Sueur), in the lakes of the Northeastern Highlands, Wisconsin
In an earlier study (Hile, 1936) a detailed investigation was presented of the age and growth of the ciscoes of Trout Lake, Musckellunge Lake, Silver Lake, and Clear Lake in northeastern Wisconsin. It was demonstrated that the growth rate of the cisco varies widely from lake to lake within the same geographical area, and that these differences in growth rate show a close correlation with certain e
