ENTOMOLOGISTS, BOTANISTS, and AGRICULTURISTS all
have occasion to concern themselves with bees. The en-tomologist is fascinated by their complex behavior pat-terns, the botanist needs to evaluate their significance infloral biology, and the agriculturist must take them into account as vital factors in crop production. Finally, the apiculturist often wishes to...

In July and August 1961, nine lots of 500 juvenile silver salmon each were subjected to one-, two-, three- and four-week periods of complete starvation. The three- and four-week periods produced the best growth checks for that time of year, but were generally of inferior quality to those produced in...
This report describes the preliminary results of a study to compare effects of clear-cut and staggered logging on fish and other aquatic resources in small headwater streams. The results of this study were published in ODFW Fishery Research Report 9 in 3 parts.
Coastal cutthroat ecology: F-72-R-2 This document contains the initial results of a study initiated in 1965 to determine the magnitude of the cutthroat trout fishery on the Siuslaw River estuary, as well as the contribution of hatchery fish to the catch.
Kokanee Ecology F-71-R-1 This document is a report on the preliminary investigation into the Kokanee salmon in Odell Lake. As such, it includes catch results of Kokanee from various fishing vessels and days, as well as for fry from trawling. Data includes sizes of fish at various depths and times....
This report measures the effects of logging on the production and yield of Coho salmon, coastal cutthroat, and steelhead trout in small coastal streams. It contains descriptions of the physical and biological environment before logging, and describes some immediate effects of logging, such as such as a decrease in dissolved...
This document discusses the influence of density, fertilization, and the environment on the growth, survival, and yield of salmonid fry reared in freshwater impoundments.
