Morphological and Histological Study of Kidney in Juvenile Great Sturgeon (Huso huso) and Persian Sturgeon (Acipenser persicus)
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...
متن کاملCryopreservation 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 کاملLactococcus lactis subsp. lactis infection in Bester sturgeon, a cultured hybrid of Huso huso × Acipenser ruthenus, in Taiwan.
Approximately 5300 hybrid sturgeons with an average body weight of 600-800 g were farmed in 3 round tankers measuring 3m in diameter each containing 28,000 L of aerated groundwater. According to the owner's description, the diseased fish had anorexia, pale body color, and reddish spots on the abdomen. The morbidity and lethality rates in this outbreak were about 70% (3706/5300) and 100% (3706/3...
متن کاملHeteroplasmy in the mtDNA control region of sturgeon (Acipenser, Huso and Scaphirhynchus).
Data from 1238 fishes from 19 sturgeon species and 1 paddlefish were used to analyze heteroplasmy in sturgeon. Lengths of central repeat units ranged from 74 to 83 bp among sturgeon species. No repeat sequence was found in the paddlefish, Polyodon spathula. A general feature of the repeat units was the presence of termination associated sequence (TAS) motifs. About 50% of 138 interspecific muta...
