Food relations and production of cutthroat trout, Salmo clarki clarki Richardson, in an experimental stream

Creator:: McIntyre, John D.
Abstract:: Production, food consumption and food habits by groups of small, mixed and large sizes of cutthroat trout were studied in enriched and unenriched sections of the Berry Creek Experimental Stream, Oregon State University.

Origin and distribution of the fish fauna of the Harney Basin, Oregon

Creator:: Bisson, Peter Andre
Abstract:: A theory of the origin and distribution of fishes in the Harney Basin is presented. Blitzen River, the hydrographically and ecologically isolated creeks, and the upland tributaries of Silvies River all contain populations derived from the basin's Pleistocene connection with Malheur River of the Snake system. Colonization of many streams...

Limnology of Upper Klamath Lake, Oregon, with emphasis on benthos

Creator:: Hazel, Charles R.
Abstract:: Aspects of the limnology and benthic ecology of Upper Klamath Lake, Oregon, are described emphasizing those features that identify its uniqueness. The lake is large, shallow, and characterized by nuisance abundances of Aphanizomenon flos-aquae and midge flies. Results of this study indicate that it does not stratify and dissolved oxygen...

Growth of channel catfish, Ictalurus punctatus (Rafinesque), fed artificial diets in ponds near Corvallis, Oregon

Creator:: Suraswadi, Plodprasop
Abstract:: The experiment was conducted at the Soap Creek farm ponds near Corvallis, Oregon. Oregon Moist Pellet and Purina Trout Chow at three different rates of feeding for each diet were used to feed fingerling channel catfish stocked at the rate of 1,000 per acre. A complete random design and Fisher's...

Creator:: Phillips, Glenn R.
Abstract:: The effects of a sublethal concentration of dieldrin (0. 2 ppb) in the water on the growth and body composition of underyearling rainbow and cutthroat trout held in aquaria and fed different rations of tubificid worms or Oregon moist pellets were studied at Oak Creek Fisheries Research Laboratory, Oregon State...
