Brown trout was selected because it is&amp;nbsp;the most recreationally and economically important species in the study areas.&amp;nbsp;Habitat models are designed for a wide variety of planning applications where habitat ecology&amp;nbsp;is an important consideration in the decision process. Habitat Suitability Index curves used in&amp;nbsp;this study describe the instream suitability of the habitat variables most closely related to&amp;nbsp;stream hydraulics and channel structure (e.g., velocity, depth) for two life stages of the brown&amp;nbsp;trout (adults and juvenile). The Brown Trout data are used provisionally to the complete&amp;nbsp;absence of any local HSI development. For this preliminary application, depth and velocity&lt;/div&gt;
&lt;div&gt;values were converted into their corresponding habitat suitability index values using a GIS&amp;nbsp;software.&amp;nbsp;Among the HSC examined here, there were those that were cited by Boove (1978) and&amp;nbsp;Raleigh et al (1986) and their development is based on literature sources or professional&amp;nbsp;opinion. The demonstration applied here clearly identifies some of the utility in using HSC to&amp;nbsp;potentially identify critical low-flow periods, where additional flow reductions may adversely&amp;nbsp;affect water use, recreation, and aquatic species. The proposed method should be&amp;nbsp;complemented with the ecological information of native fish species, and tested for&amp;nbsp;transferability in other regions of Greece.&lt;/div&gt;</style></abstract></record></records></xml>
