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...

The objectives of this study were to evaluate fish guild compositions and national river health using a multi-metric model of the Korean index of biological integrity using fishes (K-IBIF) in four major Korean watersheds along with water chemistry and habitat quality. Tolerant and omnivore fish species dominated all the watersheds, and the proportions of tolerance guilds and trophic guilds refl...

conclusions a high prevalence of sleep disorder was found in this population, specifically among female students. analysis of the relationship between sleep disorder and academic performance indicates a significant relationship of psqi scores with marital status, habitat, smoking, physical activity, and academic performance. results a total of 177 respondents, with a response rate of 55%, were ...

~ Riparian vegetation increases stream channel complexity and directly contributes to aquatic habitat through inputs of logs and branches. In turn, the provision of complex habitat has a major influence on aquatic biodiversity. ~ Logs and branches can enhance stream stability, regulate sediment transport and exert significant control on channel complexity in bedrock rivers and channel geomorpho...

the objective of this study was to diagnose integrative ecological health of an urban stream,which is located in the asian temperate region. the research approach was primarily based on the index ofbiological integrity (ibi) using fish assemblage and a qualitative habitat evaluation index (qhei). and these indexes were compared with long-term conventional chemical dataset during 1996-2005. for ...

The fish assemblage structure was analyzed in the streams of Kumaon Himalaya of Uttarkhand State, India. Seven sites were sampled by using different fishing gears during Jan, 2007 to December 2008. The physical features like stream habitat, stream classifications, fish assemblage at different sites, habitat preference and riparian vegetations were registered for each site. In the present invest...
