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...

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...

this study compared the effects of different levels of dietary fat on growth performance, liver enzymes and blood biochemical of juvenile siberian sturgeon (acipenser bearii) was designed for 12 weeks. for this reason 135 fish (15.6 ± 0.33g; mean ± sd) at nine 500 liter fiberglass tanks, each one containing 15 fish. three experimental diets with the same protein (42 %) and 3 fat levels 10, 15 a...

The Sox9 gene of Acipenser sturio, one of the most primitive vertebrates, was analyzed. No sex-specific differences were observed. Sturgeon Sox9 consists of three exons and two introns with completely conserved exon-intron boundaries showing high levels of homology to other vertebrate Sox9 sequences, especially in the N-terminus region containing the HMG box. We found strong evidence for negati...
