“…Levels of basal cortisol in serum, in this study were similar to other previous studies on sturgeons, such as in Scaphirhynchus albus , Acipenser medirostris , Acipenser oxyrinchus , Polyodon spathula and H. huso (Barton, Rahn, Feist, Bollig & Schreck ; Barton, Bollig, Hauskins & Jansen ; Lankford, Adams & Cech ; Baker, Wood, Litvak & Kieffer ; Webb, Allert, Kappenman, Marcos, Feist, Schreck & Shackleton ; Hoseini, Hosseini & Nodeh ; Yousefi, Abtahi & Kenari ). However, basal levels in this study were considerably lower than those of previous studies on the same species (Kamangar, Rasaee, Amiri, Abtahi & Bahmani ; 35 ng mL −1 ; Hajirezaee, Rafiee & Hushangi ; 100 ng mL −1 ; Falahatkar, Akhavan et al . ; 10 ng mL −1 ; Falahatkar, Poursaeid, Efatpanah, Meknatkhah & Biswas ; 18–45 ng mL −1 ).…”

The physiological ionoregulatory, metabolic and immune responses of Persian sturgeon, Acipenser persicus, to acute stress were investigated. Water levels were lowered to the fish dorsal scutes, and fish were blood-sampled before stress (pre-stress), and 0, 6, 24 and 72 h after stress. Results showed that serum cortisol rapidly increased after stress, returning to initial levels at 24 h. Serum glucose significantly increased at 6 h, declining to the pre-stress levels at 72 h. Serum triglyceride and cholesterol showed significant decreases at 0 h, then increasing to higher than the initial levels at 72 h. Serum T 3 and T 4 significantly decreased at 0 h and recovered at 72 h. Serum chloride levels showed no significant changes while serum calcium showed a significant increase at 0 h and a further increase until 72 h poststress. Serum total protein and alternative complement activity showed a significant initial decrease and recovery at 24 h with further increase at 72 h. Serum lysozyme activity increased significantly at 24 and 72 h after stress. Serum total immunoglobulin significantly increased at 0 h and peaked at 24 h. This is the first work showing thyroid hormone and immunological responses in Persian sturgeon subjected to stress, and the results show that this species follows a classical hormonal and energetic stress response, although, in the low range among the sturgeons. Although transient and moderate, confinement stress can induce significant changes in the innate immune response.

“…Plasma lactate levels were analyzed based on the colorimetric method described by Barton et al (). Analysis of insulin‐like growth factor I (IGF‐I) was measured by RIA according to Kamangar et al (), using a commercial kit (Mediagnost, Reutlingen, Germany). As both purified sturgeon IGF‐I and specific antibody against this antigen were unavailable, IGF‐I concentrations were measured using a polyclonal antihuman IGF‐I and human IGF‐I as antigen, following the manufacturer's instructions.…”

The influence of three different initial stocking densities (low stocking density [LSD] = 1.5 kg/m2; medium stocking density [MSD] = 3 kg/m2; and high stocking density [HSD] = 6 kg/m2) in flow‐through systems was evaluated on growth and welfare in beluga, Huso huso, and ship sturgeon, Acipenser nudiventris, juveniles for 2 mo. Fish were kept in 18 concrete square tanks (2.0 × 1.0 × 1.2 m3) at 22.3 ± 0.4 C and under a natural photoperiod. In both species, the growth performance in terms of final body weight, weight gain, specific growth rate, and feed intake significantly decreased with increasing stocking density (P < 0.05). In both species, the percent of neutrophils increased after 60 d of trial (P < 0.05). Moreover, hematocrit and white blood cell counts increased after 60 d of trial in ship sturgeon (P < 0.05). Plasma immunoglobulin significantly decreased with increasing stocking density in both species. Plasma insulin‐like growth factor I decreased with increasing stocking density in beluga; however, it was not affected in ship sturgeon. Overall, these results showed that the LSD group in both species demonstrated more homogeneous and higher growth rate than the MSD and HSD groups.

“…Serum cortisol level was determined using a commercial RIA kit (Coated Tube Cortisol 125 I RIA Kit, BNIBT, Beijing, China) according to the manufacturer's instruction. The assay using the cortisol RIA kit was validated by demonstrating parallelism between the sample dilution curve and the standard curve (Kamangar et al 2007). In this assay, 500 ll 125 I-cortisol and 25 ll fish serum/cortisol standard were added into the assay tube coated with anticortisol antibody and incubated for 45 min at 37°C.…”

This study investigated the effects of different stocking densities on growth and serum concentrations of thyroid hormones and cortisol in Amur sturgeon, Acipenser schrenckii. Fish were reared at low, medium, and high stocking densities (initial experimental densities were 0.30, 0.75, and 1.78 kg m(-2), respectively) for 70 days. The results showed that high stocking density had negative effects on growth and feeding efficiency, and altered serum levels of thyroid hormones and cortisol in Amur sturgeon. A significant decrease in specific growth rate was observed as stocking density was increased. The feeding rate decreased significantly in the medium and high density groups, indicating that high stocking density reduced the food consumption of sturgeon. Food conversion ratio increased with increasing stocking density, suggesting that high stocking density might inhibit fish growth through decreasing food conversion efficiency. Serum concentrations of total triiodothyronine, free thyroxine, and free triiodothyronine were inversely related to stocking densities, whereas serum total thyroxine level of sturgeon stocked at different densities remained stable. Also, higher stocking density resulted in an elevation of serum cortisol level, indicating that the sturgeon stocked at the higher density experienced density-dependent physiological stress. These results suggest growth suppression caused by high stocking density might be related to both crowding stress and the declines in peripheral circulating levels of thyroid hormones, as well as associated with the reductions in both food consumption and food conversion efficiency.
