“…The freshwater osmolality and ion levels found in this study were similar to those found in other acipenserids (McEnroe & Cech, 1985;Altinok et al, 1998;LeBreton & Beamish, 1998;McKenzie et al, 1999;Martinez-Alvarez et al, 2002;Rodriguez et al, 2002;Baker et al, 2008;Amiri et al, 2009;He et al, 2009;Zhao et al, 2011) including studies on A. brevirostrum (Jarvis & Ballantyne, 2003;Krayushkina, 2006). As noted in previous studies, the resting freshwater osmolyte concentrations of acipenserids are generally lower than those found in most teleosts (Kieffer et al, 2001).…”

This study focused on the acute physiological responses to saltwater exposure in juvenile shortnose sturgeon Acipenser brevirostrum. In two separate laboratory experiments, 2 year-old A. brevirostrum were exposed to either full (32) or half-strength (16) seawater for up to 24 h. First, oxygen consumption rates were used to estimate the metabolic costs over 24 h. Secondly, blood and muscle samples were analysed at 6, 12 and 24 h for water loss, various measures of osmoregulatory status (plasma osmolality and ions) and other standard haematological variables. Juveniles exposed to full-strength seawater showed significant decreases in oxygen consumption rates during the 24 h exposure. Furthermore, seawater-exposed fish had significantly increased plasma osmolality, ions (Na(+) and Cl(-)) and a 17% decrease in total wet mass over the 24 h exposure period. To a lesser extent, increases in osmolality, ions and mass loss were observed in fish exposed to half-strength seawater but no changes to oxygen consumption. Cortisol was also significantly increased in fish exposed to full-strength seawater. While plasma protein was elevated following 24 h in full-strength seawater, haemoglobin, haematocrit and plasma glucose levels did not change with increased salinity. These results imply an inability of juvenile A. brevirostrum to regulate water and ions in full-strength seawater within 24 h. Nonetheless, no mortality occurred in any exposure, suggesting that juvenile A. brevirostrum can tolerate short periods in saline environments.

“…Rochard et al, (1990) identified three types of life history style in sturgeons and according to them the Persian sturgeon belongs to type 2. Similarly, the acclimation capacity of Persian sturgeon to various salinities fits also the scheme suggested by Krayushkina (2006). Spending most of its life in the Caspian Sea with salinities ranging between 10 to 15 ppt.…”

The osmoregulatory system was studied in wild adult and reared juvenile Acipenser persicus to determine the effect of habitat and salinity on the ionic system. The mean osmolarity in blood serum of sturgeons from the Caspian Sea, estuary, the Kouraneski ponds and the rearing tanks were 305.3 ± 14.3, 308.7 ± 25.8, 265.0 ± 19.1 and 259.3 ± 8.8 mosmol/L, respectively. The mean concentrations of Na + were 151.2 ± 6.3, 152.2 ± 8.4, 142.5 ± 5.9 and 131.4 ± 4.1 meq/L, whereas mean concentrations of K + were 2.7 ± 0.9, 3.6 ± 0.9, 3.1 ± 0.5 and 2.6 ± 0.5 meq/L, respectively.The determined concentrations for Magnesium ion in fish of the four studied origins were 1.5 ± 0.2, 1.5 ± 0.3, 0.8 ± 0.2 and 0.7 ± 0.2 meq/L, respectively and those for Calcium were 2.31 ± 0.51, 2.61 ± 0.51, 1.85 ± 0.58 and 1.46 ± 0.43, respectively. The Pearson's correlation coefficient and regression equations indicated that Mg ++ (r = 0.38) and Na + (r = 0.41) are among the effective ions to influence the blood serum osmotic pressure in A. persicus in brackish water and fresh water, respectively. The study also looked at potential differences between males and females, however the osmotic pressure in blood serum were habitat but not sex dependent.

A 12 week growth study was carried out to investigate the supplemental effects of dietary garlic powder (GP) on growth, feed utilization and whole body composition changes of fingerling sterlet sturgeon Acipenser ruthenus (averaging weight, 5.5 g). Following a 24-h fasting, 540 fish were randomly distributed to each of 18 tanks (30 fish/tank) under a semi-recirculation freshwater system. The GP of 0.5% (GP0.5), 1% (GP1), 1.5% (GP1.5), 2% (GP2) and 3% (GP3) was added to the control diet (GP0) containing 43% protein and 16% lipid. After the feeding trial, weight gain (WG) of fish fed GP1.5, GP2 and GP3 were significantly higher (p<0.05) than those of fish fed GP0, GP0.5 and GP1. Feed efficiency and specific growth rate (SGR) showed a similar trend to WG. Protein efficiency ratio of fish fed GP1.5, GP2, and GP3 were significantly higher (p<0.05) than those of fish groups fed the other diets. A significant difference (p<0.05) was found in whole body composition (moisture, crude protein, crude lipid, ash, and fiber) of fish at the end of the experiment. Significantly higher (p<0.05) protein and lipid retention efficiencies (PRE and LRE) were also found in GP1.5, GP2, and GP3 groups. Broken-line regression model analysis and second order polynomial regression model analysis relation on the basis of SGR and WG indicated that the dietary optimal GP level could be greater than 1.77% and 1.79%, but less than 2.95% and 3.18% in fingerling sterlet sturgeon. The present study suggested that dietary GP for fingerling sterlet sturgeon could positively affect growth performance and protein retention.
