Comments: Construction of the dam on the Zayandeh River (where it is known as <i>Petroleuciscus esfahani</i>) has altered the ecology of the river system.  However, its effects on the distribution and numbers of the new species is unknown.  It may be relatively secure in higher tributary streams but demands on water resources from this and other rivers on the central desert plateau of Iran have increased markedly as the human population of the country has doubled in 30 years.  Freshwater resources are under threat, exacerbated by droughts, and all species found in these desert or semi-desert areas are under stress (Ref. 84539),
