Cryopreservation of Beluga (Huso huso) Sperm: Effect of Different C
Semen obtained from four Beluga males (Huso huso) was cryopreserved using extender; Tris-sucroseKCl (30mM Tris, 23.4mM sucrose, 0.25mM KCl, PH 8.0) supplemented with MeOH at concentration of 5%, 10% and 20%. Semen was diluted, respectively, with ratios of 1:0.5, 1:1 and 1:2 with extender and frozen in liquid nitrogen vapor.Frozen sperms after 30 and 60 days were excluded from freezing. Experime...
متن کاملEffect of freezing rate on motility, adenosine triphosphate content and fertilizability in beluga sturgeon (Huso huso) spermatozoa.
Broodstock selection programs are currently underway for sturgeon species. To complement and further these selection programs we need to develop sperm cryopreservation procedures. In the present study, we describe the effects of freezing rate (-10°C, -15°C, -20°C, -30°C and -40°C/min) on gamete quality characteristics (i.e., duration of motility (s), motility percentage (%), ATP content (nmol/1...
متن کاملMineral Status of Juvenile Beluga (Huso huso) Fed Citric Acid Supplemented Diets
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...
متن کاملReproductive effects of dietary soy phytoestrogens, genistein and equol on farmed female beluga, Huso huso
In this study, 54 five-year-old farmed female beluga at stage II of sexual maturation were treated with 0 (control), 0.2, 0.4, 0.8 and 1.6 g of dietary soy equol (EQ) and genistein (GE) per each kilogram (kg) of diet during a year. Blood samples were collected and ovarian biopsy was performed quarterly. Results showed that 64.4% of the Huso huso sexually matured at EQ 0.4 g/kg and reached stage...
متن کاملEffect of hypoxia, normoxia and hyperoxia conditions on gill histopathology in two weight groups of beluga (Huso huso)
The influence of dissolved oxygen concentration on gill histopathology of great sturgeon (Huso huso) was evaluated in two weight classes (initial weight 280.9?49.2 g and 1217.9?138.1 g respectively). Oxygen treatments included hypoxia (2-3 mg/l), normoxia (5-6 mg/l) and hyperoxia (9-10 mg/l). The fish were acclimated to experimental tanks for one week then randomly distributed into 9 tanks i...
