Founders of fish culture - European origins
Just where true fish culture appeared in history depends entirely upon what one considers fish culture to be. If the transportation of fishes from regions of plenty to those of few is to be regarded as fish culture - as it is by some even today - then this story should start in remotest antiquity and deal with an amazing series of failures. However, fish culture to be classed as a science must inc

Mortality of fish in Lake Erie
The food habits of Blue Grouse vary from a simple winter diet that is made up predominantly of coniferous needles to a complex diet during the summer months, characterized by great variety of foods including green leaves, fruits and seeds, flowers, animal matter and coniferous needles. The spring and fall, which represent the transition periods between these two, are characterized by feeding habit

Net selectivity on the Great Lakes
Two experiments, using 784 bobwhite quail chicks, were conducted at the Patuxent Research Refuge, Bowie, Maryland, to find a growing diet that would meet wartime restrictions. In 1941 a diet containing 14 per cent sardine fish meal was formulated and gave satisfactory results from the standpoints of survival and growth. Since fish meal now is scarce, search was made for a diet without war-restrict

Summary of investigations on the morphometry of the cisco, Leucichthys artedi (Le Sueur), in the lakes of the northeastern highlands, Wisconsin
The morphometric studies on the cisco or lake herring, Leucichthys artedi (Le Sueur), which are briefly summarized in this paper are part of a program of investigation of the fishes of the lakes in the northeastern highland district, Wisconsin. For the morphometric studies, 1,548 specimens were employed, all of them collected in the summers of 1931 and 1932 from four 'type' lakes, selected on the

Low production may not mean depletion
Five feeding tests were conducted at the Patuxent Research Refuge, Bowie, Maryland, to determine the value or dwarf and smooth sumac fruits as the sole diet of quail, as well as a supplement to other feedstuffs.....When whole sumac fruits were force-fed quail, either alone or in combination with millet seed, many of the sumac seed were defecated undigested, whereas the millet seed was digested.

Age determination of fish from scales; method and application to fish cultural problems
THE SCIENCE of "scale reading", or determination of the age of fish from the examination of their scales, is less than 40 years old. Yet today the publications on the subject are to be numbered by the hundreds, and there is scarcely any phase of fish and fishery work that has not been benefited by this powerful tool for investigation. Fish culture is no exception to this rule. It is because of the
