Palíková M., J. Mare‰ , J. J i rásek : Characteristics of Leukocytes and Thrombocytes of Selected Sturgeon Species from Intensive Breeding. Acta Vet. Brno, 1999, 68: 259–264. Analysis of leukocyte and thrombocyte characteristics in Acipenser baerii, Acipenser stellatus and Huso huso sturgeons at the age of about 200 days kept under intensive breeding conditions is presented. The differential le...

Experimental trials of acclimatization of juvenile Persian sturgeon, Acipenser persicus to different salinites of 0,5,10, 15ppt were studied. The juvenile Persian sturgeons in three weight classes (1.5, 3, 5g) have been  transfered from freshwater to different concentrations of saline water.  Na+, k+, Cl- concentrations of blood serum and the changes in the number and size of chloride cells wer...

In order to does this study, 150 Persian sturgeons having 75g mean weight transferred to 500 liter tanks. After dividing the fishes into two groups (experimental and control), the fingerlings fed by concentrate food that contained different levels of Zataria multiflora essential oil (15, 25, 50, 100 g/kg) for 8 weeks. Finally, sampling carried out on blood and serum of fishes. After preparin...

Abstract Although the Cretaceous is widely regarded as a time of great evolutionary transition for freshwater fish fauna North America, fossil record this period notoriously poor, consisting mostly fragments and isolated skeletal elements. Exceptions include acipenseriforms, discussed in paper, some exceedingly rare teleosts. Here we describe two new species well-preserved sturgeons (Acipenseri...

this study was done on 4 and 5 years old great sturgeon cultured in brackish water ponds in bafgh salt water fisheries research station during one year. we examined somatic growth indices and effects of different diets on blood parameters and total length and weight. diet with constant protein (%40) and different energy levels (400,425,450,475 cal/100g) were fed to 74 pieces of great sturgeons ...

In quantitative real-time PCR, the mRNA level can be quantified in relative terms based on the expression ratio of mRNAs of the target gene and an internal reference gene. Since, an internal standard should be expressed at a constant level among different tissues of an organism at all stages of development, and should be unaffected by the experimental treatment, the stability of different refer...

For rare and endangered species, bioenergetics modeling can represent a valuable approach for understanding issues of habitat value and connectivity among potential habitats within nurseries in restoration programs. We used multivariable bioenergetics and survival models for Atlantic sturgeon to generate spatially explicit maps of potential production in the Chesapeake Bay. For the period 1993e...
