the aim of this study was to investigate on obtained caviar quantity status of sturgeon at fishing grounds of the southwestern caspian sea. data of catches by means of fixed gill nets in sturgeon fish fishing grounds and beach seine were used during 5 years survey (2005-2009). a total of 1361 female sturgeon was caught including: 788 acipenser persicus, 410 a. stellatus, 60 a. guldenstaedti, 70...

species composition, relative abundance, absolute abundance and biomass of sturgeon species were studied during the years 2008-2009. eighty five stations were covered in the stratified random sampling design in depths less than 1om using 9m bottom trawl (head line) and in depths more than 10m using 24.7m bottom trawl (head line). more than 70 specimens of acipenser persicus were caught during t...

The micropyle number in the ova of sturgeon species from the South Caspian Sea was investigated. The study was conducted on female broodfishes of three species of sturgeon (Persian sturgeon Acipenser persicus, Stetates sturgeon A. stellatus and great sturgeon Huso huso) included 44 Persian sturgeon, 13 stellate sturgeon and 8 great sturgeon specimens. Fifty eggs were randomly collected from eac...

although the persian sturgeon, acipenser persicus , is a commercially valuable sturgeon species of the caspian sea, but there are only few reports about its parasite fauna in the southern part of the caspian sea. in this study, a total of 209 individuals of persian sturgeon were collected from two regions in the southwestern of caspian sea (guilan province, iran) from march 2009 to may 2011. af...

persian sturgeon (acipenser persicus) is a valuable fish caught in the caspian sea. in this study, effect of frying, the most common cooking methods on nutritional properties of the persian sturgeon fillet were investigated. the raw and fried samples were analyzed for amino acid composition, protein and fat content, in vitro digestibility and nutritional parameters. the results showed that the ...

the late sexual maturity in sturgeon and the absence of morphological differences between males and females makes sex discrimination difficult. identification of sex at an early life stage is of high interest in caviar production because it allows efficient selection of females. in this study, the genome of 10 mature male and 10 mature female specimens of persian sturgeon (acipenser persicus...
