Impending extinction of salmon, steelhead, and trout (Salmonidae) in California

Environmental Biology of Fishes, 2012
California contains the southernmost native populations of most Pacific Coast salmon and trout, many of which appear to be rapidly headed toward extinction. A quantitative protocol was developed to determine conservation status of all salmonids native to the state.

Focused aquifer regeneration produced outsized gains for a threatened fish in a populated, dryland watershed

Ecosphere
A combination of groundwater pumping and shifting precipitation patterns is drawing down aquifer levels in many of the world's drylands and is predicted to generate widespread loss of perennial streamflows over the next few decades.

Growth of coastal cutthroat trout, Oncorhynchus clarkii clarkii, in intensively monitored urban and natural streams in Puget Sound and the Strait of Juan de Fuca

Frontiers in Ecology and Evolution
Coastal cutthroat trout (Oncorhynchus clarkii clarkii) are considered indicators of stream health, yet paradoxically, they often persist in degraded urban watersheds. To evaluate how cutthroat trout perform in a small urban watershed, we compared several
