River, north of Iran were sampled to study the relationship between fish
assemblage and habitat variables, including elevation, water depth, river
width, river slope, current velocity, number of large stone, average stone diameter,
substrate index, potamal cover index and periphyton cover index. Canonical
correspondence analysis was used to determine the relationship between fish
assemblage and habitat variables. The results indicated that presence-absence
and abundance of <i>Alburnoides samiii </i>were related to elevation, depth,
number of large stone, stone diameter and velocity; presence-absence and
abundance of <i>Oxynoemacheilus bergianus, Cobitis keyvani, Barbus cyri </i>, <i> </i>and <i> Ponticola iranicus </i>
were related to number of large stone, stone diameter, velocity, elevation, and
depth; and presence-absence and abundance <i>Acanthobrama microlepis, Carassius
auratus </i>, <i> and Pseurasbora parva </i>
are related with large stone, slope, elevation, and depth. The relationships
between habitat variables and fish assemblage provide insight into their
ecology and can aid effective fisheries management in the Sefidrud River basin <span dir="rtl"> </span> <span dir="rtl"> </span> <b> <span lang="ar-sa" dir="rtl" xml:lang="ar-sa"> <span dir="rtl"> </span> <span dir="rtl"> </span>. </span> </b> </span> </p> <p> </p> </div>}, number={2}
