Histomorphogenesis on hindbrain in Huso huso (Beluga sturgeon) larvae
Comparative Clinical Pathology, 2019This study has been done on evolution and morphology of hindbrain structure, during larvae life from 1 to 54 dph on Huso huso. It was concentrated on significant cerebellum and medulla oblongata. The cerebellum occupied the rostral part of dorsal wall of fourth ventricle. The fourth ventricle was visible on 1 day old and by aging was majorly.

Beluga (Huso huso, Brandet 1869) bioenergetics under dietary methylmercury
Fish Physiology and Biochemistry, 2008Recently, there have been reports of increasing amounts of mercury (Hg) in muscles of beluga (Huso huso, Brandet 1869) in the Caspian Sea which exceeds its guideline level for food in the UK. Our intensive effort was to investigate the effects of dietary methylmercury (MeHg) on Beluga bioenergetics.

On the adrenergic system of ganoid fish: the beluga,Huso huso(Chondrostei)
Acta Physiologica Scandinavica, 1981The adrenergic system of the beluga,Huso huso, was studied by glyoxylic acid fluorescence histochemistry, analyses of catecholamine content in various organs and studies of the effects of acetylcholine and adrenaline on isolated strip preparations from blood vessels, spleen, atrium and ventricle.

Abstract Fisheries management has expanded from a traditional focus to a more holistic model based on a model describing the change in the number of generations of fish under the influence of age-dependent natural mortality and harvesting. We calculated the abundance, biomass, production, natural, total loss and catches from the conditional ...

The metabolic effects of feeding and fasting in beluga Huso huso
Marine Environmental Research, 2012A six week-study was conducted to determine the effect of starvation and feeding on growth, hematology and biochemical variables in sub-yearling beluga. Fish were placed on six feeding strategies: i) starved condition for 6 weeks, ii) a 2-week starvation, 2-week feeding and 2-week starvation, iii) a 2-week feeding, 2-week starvation and 2-week feeding,

Animal Reproduction Science, 2013
The ultrastructure and morphology of beluga spermatozoa (Huso huso) (Acipenseridae, Chondrostei) were studied by scanning and transmission electron microscopy. Spermatozoa of 51.27 ± 4.71 μm total length (mean ± SD) were typical of sturgeon and paddlefish spermatozoa.

Proteome modifications of juvenile beluga (Huso huso) brain as an effect of dietary methylmercury
Comparative Biochemistry and Physiology Part D: Genomics and Proteomics, 2009Methylmercury (MeHg) is the most toxic form of mercury which is bioaccumulated in the aquatic food chain. It has been shown that one of the main targets of MeHg toxicity is the brain, but there is little knowledge of the molecular mechanisms of its toxic effects.

Fatty acid composition in farmed great sturgeon Huso huso
Comparative Clinical Pathology, 2011In this study, fatty acid profiles in farmed great sturgeon Huso huso were determined and results compared with those of other farmed sturgeon species. C18:1, C18:2, C16:0, C18:3, and C18:0 were the main fatty acids found in great sturgeon flesh and represented approximately 88% of total fatty acids.

Responses to handling and confinement stressors in juvenile great sturgeonHuso huso
Journal of Fish Biology, 2009The effects of acute stressors on physiological responses of juvenile great sturgeon or belugaHuso husoL. were investigated in two experiments. In the first experiment, fish were handled by placing them in containers at either low density (LD, one fish l−1) or high density (HD, four fish l−1) for 60 s.

Histological Studies on the Otolith of Huso huso, Chondrostei
1991In Agnatha, Chondrichthyes, Dipnoi, Amphibia, Reptilia, Aves and Mammalia, the otolith is composed of many granules [1–8]. But in Teleostei of Actinopterygii, it is done of the crystals and organic matters which deposit periodically in concentric circles around one or a few spherical granules [3, 4, 7–9].
