the genus alburnoides jeitteles, 1861 in iran is reviewed, and diagnoses are presented for all eight recognized species. alburnoides eichwaldii, a. holciki, a. idignensis, a. namaki, a. nicolausi, a. petrubanarescui, a. qanati and a. tabarestanensis are considered valid and three new species are described: alburnoides coadi sp. n., from namrud river in kavir basin, a. parhami sp. n., from atrak...
population of vimba vimba persa was investigated using microsatellite markers originated from two regions along the iranian coastline of southern caspian sea (anzali lagoon and havigh river in gilan province). totally 153 alleles were identified. the highest number of alleles per ca3 loci was 17 and the lowest 3 in z8145 loci with means of 7.6. observed and expected heterozygosity averages were...
The results of this study indicated that the synoptic patterns that lead to heavy rainfall in 22 March 1996, 24 mar 1995 and 17 November 1994 in the northern portion of FARS province includes: the low pressure that located in eastern part of Mediterranean and Black sea and southern part of Caspian Sea that created by trough that located at the middle level of atmosphere. In addition to this low...
traditionally, capoeta populations from the southern caspian sea basin have been considered as capoeta capoeta gracilis. study on the phylogenetic relationship of capoeta species using mitochondrial cytochrome b gene sequences show that capoeta population from the southern caspian sea basin is distinct species and receive well support (posterior probability of 100%). based on the tree topologie...
abstract many people know the important effects of caspian sea winds and storms on the economy of three provinces of iran including gilan, mazandaran, and golestan that they form one exclusive and extent area which have moderate and humid climate. this paper used a synoptic climatologically approach, which combine a number of atmospheric factors. using daily and monthly winds data including the...
A partial sequence of the mtDNA ND5 gene region was used for population study in Persian sturgeon (west and east areas of southern Caspian Sea). The result showed that although this approach was informative for phylogenetic study in sturgeon, it was less informative for population study in Persian sturgeon.

The bony fishes of the Caspian Sea are the species whose reserves are decreasing due to Pollution, habitat destruction, exploitation and illegal fishing. Regarding the extent of illegal fishing in Golestan province and lack of sufficient studies in this regard, this study examines the changes in illegal fishing and identifies the factors involved in its occurrence. Using descriptive-analytical ...
