Intraspecific and interspecific nucleotide sequence variations of the mtDNA control region (D-loop) were studied with mtDNAs isolated from tissue specimens of more than 1400 sturgeons of nine species: Russian sturgeon Acipenser gueldenstaedtii , Persian sturgeon A. persicus , Siberian sturgeon A. baerii , Amur sturgeon A. schrenkii , Fringebarbel sturgeon A. nudiventris , sterlet A. ruthenus , ...
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...
in this study the lc50 96h values of water-soluble fractions (wsf) of the caspian sea ? exploited crude oil were determined in beluga, huso huso fingerlings. the fingerlings averaged 2.42 ? 0.11 g in weight were exposed to wsf crude oil at concentrations 24.75, 27, 29.25, 31.5, 33.75, 36, 38.25 ppm. the treatments were performed in three replicates and all changes in the specimens were determin...
lactic acid bacteria are characterized as gram-positive, usually non-motile, non-sporulating bacteria that produce lactic acid as a major or sole product of their fermentative metabolism. in this study, the presence of lactobacilli were investigated in the intestines of beluga ( huso huso) and persian sturgeon ( acipenser persicus ), inhabiting caspian sea. the obtained data showed that various...
