The horizontal distribution and vertical migrations of the limnetic zooplankton in Crater Lake, Oregon

Creator:: Hoffman, F. Owen
Abstract:: During the summers of 1967 and 1968 the horizontal distribution and did vertical migrations of zooplankton were studied within the unique environment of Crater Lake. Sampling of the horizontal distribution was done by towing plankton nets vertically in different locations. The vertical distribution was sampled by towing at different depths...

The migratory pattern of audlt sockeye salmon (Oncorhynchus nerka) in Bristol Bay as related to the distribution of their home-river waters

Creator:: Straty, Richard R.
Abstract:: The individual stocks of sockeye salmon that make up the annual spawning migration to the Bristol Bay region of Western Alaska are produced in the lakes and streams of ten major river systems, which discharge into the bay over a shoreline distance of 120 miles.

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...

Abstract:: Numerous tests were applied to rainbow trout of eleven months of age to determine whether ascorbic acid is an essential element of the diet of these fish. Although previous work had been done on this question, conflicts in the results, the large reliance upon abnormal symptoms such as lordosis and...

A review of the Gadopsidae, with a description of a new species from Tasmania

Creator:: Parrish, Richard H.
Abstract:: The taxonomic placement of Gadopsidae is discussed and an evaluation of its osteological relationships with related families is given. Similarities to the more primitive genera of the trachinoids, notothenioids, and uranoscopoids are noted and the inclusion of Gadopsidae in the Trachinoidae is recommended. A description of the geological history of...
