The aim of the present study was to detect polymorphism in Insulin like growth factor-I (IGF-I) gene of beluga (Huso huso) fish using PCR-SSCP technique and also investigation of its association with growth traits (condition factor, body length and weight). A total of 150 specimens of beluga were randomly selected and DNA was isolated from caudal fin using modified salting out method. Then two ...

beluga sturgeon ( huso huso linnaeus, 1758) fingerlings are released into the caspian sea for recruiting and enhancing commercial and recreational fishing purposes. these fingerlings are reared in fresh water, but released to the estuaries that may be caused mortalities due to acute osmotic stress. in this study, the fingerlings in whole ( in vivo ) or their gill tissue ( in vitro ) were expose...

caviar is one of the valuable and most popular fish products all over the world that are obtained from sturgeons. nowadays, the wild resources of these fishes are diminished, therefore, to meet the demand for the product, farming sturgeons has been considered. the chemical composition and the amino acids profiles of the wild and farmed roe obtained from beluga (huso huso) were compared and the ...

In this report selected examples of subcellular specializations and tissue structures of the bottlenose dolphin and beluga whale kidney are presented which illustrate some unique renal adaptations of cetaceans, and other subcellular structures are depicted for here the first time by electron microscopy. Large reservoirs of glycogen in the cortical proximal convoluted tubules, some unique bundle...

In this study, the cDNA Growth Hormone (cGH) of the Belugasturgeon (Husohuso) and Russian sturgeon (Acipensergueldenstaedtii) were cloned and sequenced, and phylogenetic relationships were examined using nucleic acid and amino acid sequences. The nucleotide sequence of the Beluga GH has an open reading frame of 645 nucleotides encoding a protein 214 amino acid residues. The signal peptide cleav...

In this research, acute toxicity (LC) of zinc oxide nanoparticle on Beluga (Huso huso) andcommon carp (Cyprinus carpio) was studied. The experiment was conducted using theOrganization for Economic Co-operation and Development (No. 202) method. For bothspecies, 96hLC10 was determined to be more than 200 mg/l. To assess the effects of zinc oxidenanoparticles on blood factors, leukocyte index coun...
