samples from five sturgeon species including persian sturgeon (acipenser persicus), russian sturgeon (a. gueldenstaedti), great sturgeon (huso huso),ship sturgeon (a. nudi-ventris) and stellate sturgeon (a. stellatus) were collected from the south caspian sea. dna was extracted from the fins, eggs and skeleton muscle of the five species. rapd markers were used for identifying different kinds of...
The effect of native probiotic (mixtures of Lactococcus lactis and Lactococcus lactis ) on growth rate and some of the hematological and immune system parameters of juvenile Huso huso were investigated.. One hundred fifty six Huso huso individual with average weight of 2.92±0. 16gr ± SD were fed by company Biomar diet (protein: 47%, lipid: 16%, carbohydrate:3/2%) that add probiotic to level of...
Sturgeon aquaculture is an emerging worldwide industry both for human consumption as well conservation. Several transmissible diseases limit this including mycosis by dematiaceous fungi such Veronaea botryosa . This study reports the first diagnosis of phaeohyphomycosis in a beluga sturgeon ( Huso huso ) Italy.
The structures of the pyruvate kinases isolated from rabbit and sturgeon muscles were compared. Both enzymes are composed of subunits of 56000 mol.wt. Amino acid compositions of the two enzymes are similar, but not identical. Examination of the peptides produced by CNBr cleavage demonstrated that there are at least some highly homologous regions in the two proteins. There are only two replaceme...
Hydroelectric dams are an important source of electricity globally, but they can also cause total dissolved gas (TDG) supersaturation in rivers. TDG harm fish through a condition called bubble trauma (GBT), which has been studied primarily salmonids, such as rainbow trout and steelhead salmon (Oncorhynchus mykiss), seldomly non-salmonids like white sturgeon (Acipenser transmontanus). We assesse...
copper (cu) is an essential element required by all living organisms, since at least 30 enzymes are known to use cu as a cofactor. cu is also toxic in excess and liver and gills are known to be target organs for it. in the present study, 240 siberian sturgeon juvenile (with initial weight 29.2 ± 3.1 g and initial length 21.8 ± 1.4 cm) were randomly distributed in 12 fiberglass tanks at 4 differ...
