A total of 48 female spirlins Alburnoides sp. from the Kesselian stream (South Caspian Sea basin, northern Iran) were examined during a period from July 2008 to June 2009 to obtain data on fecundity, and to determine the spawning season of this carp. The mean absolute fecundity of females spirlin was 1722.92 (653.88) eggs. The fecundity has positive correlation with the size of the female. The...

BACKGROUND Knowledge about Alburnoides remains lacking relative to many other species, resulting in a lack of a systematic position and taxonomic diagnosis. Basic biological information for Alburnoides has been constructed, and it is necessary to understand further and obtain more information about this species. Its phylogenetic relationships are still debated and no molecular data have been us...
a fish species prefer a particular habitat where provides its biological requirements, hence, understanding their habitat use and preferences are crucial for their effective management and protection. this study was conducted to assess the habitat use and selection patterns of alburnoides namaki , an endemic fish in jajroud river, namak lake basin, iran. the river was sampled at 18 equally spac...
