high mortality and labor costs are associated with first-feeding sturgeon culture, particularly during the period of dietary transition from live to formulated feed. therefore we investigated the effects of various feeding treatments on the survival and growth of the persian sturgeon ( acipenser persicus ) larvae during a 20-day culture period. three replicate groups (250 fish/replicate) of fir...

A study on motility of spermatozoa of the Persian sturgeon, Acipenser persicus were carried out. The time of relative cessation of sperm activity was evaluated using microscopic observation. Sperm was activated with three different swimming medium, freshwater pH 7.5, and two different buffered saline solutions, pH 7.5. Total period of the motility of A. persicus spermatozoa was shorter in fresh...

Platelet aggregation inhibitory effect and anticoagulant properties of fractions separated from the venoms of Cerastes persicus fieldi and Echis carinatus were investigated. The partial fractionation was performed on a Sephadex G-100 column. Two fractions separated from Cerastes persicus fieldi showed anti platelet aggregation activity on ADP (200 µM)-induced platelet aggregation (ca 80% inhibi...

the persian sturgeon, acipenser persicus (borodin, 1897), is an economically important species, which mainly inhabits the caspian sea. however, little is known about its population genetic structure. in this study, variation in nucleotide sequences of the mitochondrial dna (mtdna) control region of wild stock persian sturgeon was determined to assess the genetic diversity among different natura...

extract of echinops persicus is traditionally used for a long time in iran for treatment of cough and constipation. this extract is produced by activity of bug (situphilus spp.) on the plant. we documented its anti-tussive effect in rats in our previous study.the aim of this study was to assess the anti-ulcer effect of echinops persicus in an animal model. in this study we evaluated anti-ulcer ...

the effect of starvation and re-feeding was investigated on growth, hematology and biochemical parameters in juvenile persian sturgeon (acipenser persicus). three hundred and seventyfive fish (108±0.63 g) were divided into five feeding groups. the control group (c) was fed to satiation three times a day during the experiment. the four groups were starved for 1 (w1), 2 (w2), 3 (w3), and 4 (w4) w...
