According to the lactadehydrogenase locus, genetic diversity of 9 samples Volga sevryuga different origin was studied. In total, 733 pieces young sevryuga, 99 producers and 107 were four-year-olds with MPERZ. To assess variability lactate dehyrogenase allozymes, method polyacrylamide gel electrophoresis used, as most appropriate for assessing influence environment in natural domesticated popula...

–Growth rates of juvenile lake sturgeon (initial weight 8 to 9 g, temperature 17.5° C), fed twice a day on brown worms for 56 days increased from -1.5% BW/d (% body wet weight/day) at zero ration to 2.6% BW/d at a ration of 13.2% BW/d. Maintenance ration was 1.6% BW/d. Fish fed larger rations had higher energy densities and lower water content. Appetite (average volitional daily food consumptio...

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 aims of the study were to observe the dissolution profile of four types of selected fruit powder fast dissolve tablet and apply different dissolution profile comparison methods, in order to select most applicable method. Spray dried powder of pitaya, pineapple, guava and mango were used as raw material. Each type of fruit powder tablet has identical dissolution profile. Dissolution profiles...
