The effects of vitrification on the embryo viability of the Persian sturgeon (Acipenser persicus) were investigated in this study. Vitrificant solutions (VS1-VS6) were prepared by combining propylene glycol (PG) as basic cryoprotectant plus other permeable and non-permeable cryoprotectants in different concentration. Embryos at neurulation stage were selected and incubated in six vitrificant so...

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...

Objectives Astrodaucus persicus (Apiaceae) is one of the two species of this genus which grows in different parts of Iran. Roots of this plant were rich in benzodioxoles and used as food additive or salad in Iran and near countries. The aim of present study was evaluation of antimalarial and cytotoxic effects of different fractions of A. persicus fruits and roots extracts. Materials and Metho...

Legally certified sturgeon fisheries require population protection and conservation methods, including DNA tests to identify the source of valuable sturgeon roe. However, the available genetic data are insufficient to distinguish between different sturgeon populations, and are even unable to distinguish between some species. We performed high-throughput single-nucleotide polymorphism (SNP)-geno...

Aim. The aim of this study was to conduct an analysis long‐term changes in the number sturgeon populations and its relationship with fishing regime current state Ural River basin, as well develop measures for conservation restoration their resources. Discussion. Six species inhabit waters basin: Huso huso Linnaeus, 1758; Acipenser gueldenstaedtii Brandt & Ratzeburg, 1833; persicus Borodin, ...

The present study was conducted to evaluate the status of the parasite fauna in Acipenser persicus at different development stages, in order to find prevention protocols for parasitic diseases in this valuable species. For this purpose, sampling from each sex breeder, 10 egg samples, 5-day-old larvae (n = 20), 20-day-old larvae (n = 80) and fingerling of A. persicus (n = 60) r...
