We surveyed large wood volumes in relation to the distribution and density of rainbow trout Oncorhynchus mykiss and steelhead (anadromous rainbow trout) in 15 stream reaches in the upper Salinas River watershed, California, which represents the southern end of the species\^a\texteuro\texttrademark range. The main tree species contributing to large ...

Analysis of data from four extensive fish surveys in the Sacramento\^a\texteuro\textquotedblleftSan Joaquin estuary indicated that splittail Pogonichthys macrolepidotus, endemic to the Central Valley of California, declined by 62\% over a 13-year period. Splittails are now found mostly in the estuary, a fraction of their former range. In a gill-net...

We used monthly otter trawling and beach seining to sample the fishes of Suisun Marsh in the San Francisco Estuary from 1979 to 1999. We collected nearly 173,000 fish, mostly young of the year, representing 28 native species and 25 alien species. Catch data were related to temperature, salinity, water transparency, and several measures of freshwate...

We used eight microhabitat variables to examine the assumption that the variables normally included in instream flow studies are adequate to discriminate among species\textquoteright microhabitats. When eight variables were available in stepwise-discriminant analysis models to distinguish among the microhabitats of four fish species in a northern C...

Young-of-year largemouth bass in Clear Lake, California, switched from feeding largely on blue-gill (Lepomis macrochirus) to feeding largely on Mississippi silverside or on a mixture of prey species following the establishment of the silverside in the lake in 1967. Choice of prey, however, was influenced by relative abundance of the prey, the habit...

The life histories of the mimic shiner (Notropis volucellus), the common shiner (N. cornutus), and the bluntnose minnow (Pimephales notatus), from a small Minnesota Lake, were compared in order to find out how temperate fish species segregate ecologically and how accurate dietary studies are for showing ecological differences among similar co-exist...

Examination of 510 stomachs of Sacramento perch from five localities showed that they feed primarily by picking insect larvae and snails from the bottom and aquatic plants or by capturing zooplankton, fish, or emerging insects in midwater. The diet varies with season and size of fish but no daily feeding rhythms were found. Similarity of their diet...

Overall fish abundance, abundance of introduced, native, and seasonal fish groups, and species diversity declined over a 14-year period in Suisun Marsh, a portion of the San Francisco Bay estuary, and were associated with decreases in freshwater outflow and increases in salinity. Fish groups showed different patterns of abundance; large fluctuation...

The introduction of new species into aquatic communities to increase fish production is a management technique that often has created more problems than it has solved. In large measure, this is due to the inability to correctly predict impact. Loop analysis is a tool of systems analysis and may be useful in predicting systems behavior of an aquatic...
