Description and prediction of broad-scale spatial variability in expression of anadromy in female Oncorhynchus mykiss in the John Day River, Oregon, USA

Creator:

Mills, Justin S.

Abstract:

Partial migration is a common migratory behavior where some individuals in a population migrate and others do not. Patterns of partial migration can vary dramatically, especially for species that inhabit a wide range of environments. I described and predicted spatial variation in marine migration (anadromy) of female Oncorhynchus mykiss (steelhead...

An economic analysis of alternative water allocations and habitat investments for anadromous fish production, John Day Basin, Oregon

Creator:

Cerda, Arcadio Alberto

Abstract:

This thesis focuses on the economic efficiency of alternative habitat, streamfiow, and land use allocations within a major drainage of the Pacific Northwest. Specifically, productivity of present habitat and streamfiow conditions is evaluated with respect to anadromous fish species (chinook salmon and steelhead trout) in the John Day River Basin,...
