This study was carried out to investigate the supplemental effects of dietary garlic extract (GE) on growth performance of juvenile sterlet sturgeon (Acipenser ruthenus). The first experiment was designed to determine the optimum levels of garlic extract as growth promoter during 10 weeks. Three groups (two replicates/group) of 240 fish with mean body weight of 85 g were fed with diets containi...

During teleost ontogeny the larval and embryonic stages are key stages, since failure during this period of tissue differentiation may cause malformations, developmental delays, poor growth, and massive mortalities. Despite the rapid advances in sequencing technologies, the molecular backgrounds of the development of economically important but endangered fish species like the Atlantic sturgeon ...

although the persian sturgeon, acipenser persicus , is a commercially valuable sturgeon species of the caspian sea, but there are only few reports about its parasite fauna in the southern part of the caspian sea. in this study, a total of 209 individuals of persian sturgeon were collected from two regions in the southwestern of caspian sea (guilan province, iran) from march 2009 to may 2011. af...

the changes of total calcium content of persian sturgeon, acipenser persicus follicles were investigated during different stages of germinal vesicle migration. total calcium content increased during maturation and ripening of the oocytes i.e. migration of nucleus toward the animal pole. according to data, the total calcium of follicles with polarization index (pi: the ratio of the distance of t...

hematological parameters are suitable biomarkers for evaluating the potential risk of the chemicals. the aim of this study was to investigate of acute crude oil exposure on basic physiological functions of persian sturgeon, acipenser persicus. 210 juvenile persian sturgeon (9.4 ± 1g) were supplied by the rajaei fish farm in mazandaran province, iran.  juveniles were exposed to the crude oil (15...
