the black-striped pipefish, syngnathus abaster, is a species of the syngnathidae family. this study provides data on the morphometric, meristic and genetic structuring of the caspian sea pipefish, syngnathus abaster. eight morphometric characteristics based on total length and five morphometric characteristics based on standard length were analyzed. a total of 50 specimens were collected in bra...

mitochondria1 dna (mtdna) control region sequences were analyzed to evaluate the population genetic structure of persian sturgeon (acipenser persicus) in caspian sea. a total of 45 specimens were collected from the different locations of the caspian sea. mtdna control region was amplified using pcr. direct sequencing was performed according standard method. the results showed that 12 haplotypes...

The study of interaction between fish cage culture and sediment population dynamics heterotrophic bacteria in the southern Caspian Sea (Nowshahr region)

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...

mnemiopsis leidyi population activities first were recorded during the coastal observations in 2001 in which its population considerably increased afterward and now sustained the southern caspian sea. maximum summer-autumn m. leidyi abundance was recorded in euphotic layer in 2002 (851±85 ind.m-3) and maximum biomass was in 2001 with 48.1±14.4 g.m-3) while minimum were in aphotic layer. in year...

AIM There is little information about the prevalence of Corynosoma caspicum in fish particularly Gasterosteus aculeatus in Iran and the world. The aim of the present study was to find out the prevalence of acanthocephalan infection in Babolsar district, southern coastal of Caspian Sea, Northern Iran. MATERIALS AND METHODS Between September 2012 and August 2014, a total of 360 G. aculeatus fis...

The geographical distribution and ecological preferences of Haemaphysalis in domestic animals in Iran were studied 4 times a year from April 2003 to March 2005. A total of 1,622 ixodid tick specimens were collected from 3 different zones. Among them, 108 (6.7%) Haemaphysalis ticks, consisting of 6 species, were identified; H. punctata (3.4%), H. parva (0.5%), H. sulcata (0.6%), H. choldokovskyi...

Serum biochemical parameters are important aspects in the management of endangered species such as Caspiomyzon wagneri. The objective of this survey was to determine some serum ionic and metabolic parameters and those relationships in 22 migratory population of Caspian lamprey in shirood river (a river located at the south of Caspian sea). There was no significant (P<0.05) difference between le...
