Sturgeons are ancient and commercial fishes which posses’ primitive characteristics and due to their great inflections are able to live in both freshwater and marine environments. So their kidney has great ability for adaptation process. In order to find the structure and distribution of kidney nephrons in juvenile Huso huso and Acipensr persicus, sampling of head, body and caudal parts of kidn...

In this study the cranial nerves development of H. huso are explained from 1 to 54-days-old (1, 3, 6, 15, 21 and 54 days). Despite all the researches on fish brain, there are no study on nerves evolution on H. huso during their larvae life. For this research 40 samples of larvae H. huso were obtained (from each age, about six samples were selected). The specimens were maintained in fiberglass t...

Palíková M., J. Mare‰ , J. J i rásek : Characteristics of Leukocytes and Thrombocytes of Selected Sturgeon Species from Intensive Breeding. Acta Vet. Brno, 1999, 68: 259–264. Analysis of leukocyte and thrombocyte characteristics in Acipenser baerii, Acipenser stellatus and Huso huso sturgeons at the age of about 200 days kept under intensive breeding conditions is presented. The differential le...

A study was conducted to investigate the effects of dietary citric acid (CA) (0, 1, 2 and 3%) on the Calcium(Ca) and Phosphorus(P) content of muscle, scute and serum of Beluga (Huso huso) juveniles (25.1±1.9 g). After 8 weeks feeding on the experimental diets, Calcium(Ca) and Phosphorus(P) content of muscle, scute and serum were measured. The results revealed that addition with 2% and 3% CA sig...

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...

Background: The Endothelial PAS domain-containing protein 1 (EPSA1) is the key transcriptional regulator of hypoxic response and Vascular Permeability Factor (VPF) is an important growth factor for vascular development and angiogenesis. OBJECTIVES: In the present study, the levels of the EPSA1 coding gene and VPF transcripts were evaluated during Larval development of Beluga, Huso huso. METHODS...

Sturgeons are ancient and endangered species whose populations have been greatly reduced over the past few centuries due to habitat destruction overfishing for production of expensive caviar. All sturgeon listed in CITES Appendix II limit their trade; therefore, accurate identification is crucial. In this study, we performed whole-genome resequencing five species, including Kaluga (H. dauricus)...

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 , ...
