—The use of model-predicted, local-scale habitat data as inputs in analyses intended to evaluate multiscale fish assemblage–habitat relationships in streams has become increasingly common as the scale at which such studies are conducted has increased. We used fish assemblage and habitat data from 208 wadeable streams in Wisconsin and Michigan to determine whether model-predicted habitat data wo...

In theHawaiianArchipelago, shelter-dependent juvenile stages ofmany reef fishes and their coral habitats are increasingly put at risk by multiple anthropogenic stressors (e.g. overfishing and habitat loss, coral bleaching and sedimentation, respectively).We assessed coral bleaching (to identify relative susceptibility among growth forms) and the use v. availability of structurally complex and s...

Sanders, Kathryn E. M.S., Purdue University, May 2012. Relative Importance of Water Quality and Habitat to Fish Communities in Streams Influenced by Agricultural Land Use in the Cedar Creek Watershed, Indiana. Major Professor: Robert B. Gillespie. Agricultural land use has been shown to negatively impact fish communities in headwater streams that also serve as agricultural drainage ditches. The...

Snow-fed river Pinder -a tributary of river Alaknanda in central Himalaya was explored for fish assemblages and habitat specificity. Altogether 27 fish species were reported from three orders, four families and nine genera. Cypriniformes order was dominating followed by Siluriformes and Salmoniformes. Shannon-Weiner diversity index (3.09 to 4.10) and Simpson index of diversity (0.81 to 0.92) of...

Low-head dam impoundments modify local habitat and alter fish assemblages; however, to our knowledge, the pattern of how fish assemblages in the impoundments relate to local habitat, tributary position, and dam characteristics is still unclear. We used data collected in 62 impoundments created by low-head dams in headwater streams of the Qingyi River, China, to examine relationships between fis...

The Sustainable Fisheries Act of 1996 and the amended Magnuson-Stevens Fishery Conservation and Management Act elevated habitat and conservation as priorities in federal fisheries management. In particular, the Essential Fish Habitat (EFH) amendment to the Magnuson-Stevens Fishery Conservation and Management Act establishes guidelines to assist fishery managers in the description and identifica...
