“…In 2018, the Shahid Beheshti Sturgeon Restoration and Genetic Conservation Center (Rasht, Iran), released over 1.5 million sturgeon fry into these rivers [ 42 ]. However, post-release, there have been reports of considerable deaths and financial damages caused by environmental stresses [ 43 , 44 ]. Therefore, it is crucial to assess the fry’s ability to tolerate different stressors for a successful release into rivers.…”

Aquatic environments face frequent exposure to organophosphate pesticides, such as diazinon, which are frequently utilized in agriculture. The goal of this study was to evaluate the effects of diazinon exposure on fish and to investigate the potential of the HSP inducer (HSPi) in developing a defense mechanism. To achieve this, several factors were analyzed, including the HSP70 gene expression, levels of immunity markers (lysozyme, IgM, and C3), antioxidant status, and the activity of acetylcholine esterase (AChE). Stellate sturgeon (Acipenser stellatus) fry, was exposed to diazinon (25, 50, and 75% of 96h-LC50) for 6 days after pre-treatment with an HSP inducer (HSPi), TEX-OE® (a prickly pear cactus extract), for 4 hours. Two HSPi concentrations, 100 and 200 mg.L-1, were used. Pre-treatment with HSPi significantly enhanced HSP70 gene expression in the gill and liver, as well as immune markers in the blood of Acipenser stellatus. Diazinon-treated groups exhibited higher antioxidant activities of SOD, CAT, and T-AOC. Increased activity also observed in control fish pre-treated with HSPi. However, stellate sturgeon receiving both diazinon and HSPi+diazinon experienced a significant decrease in AChE activity in comparison with control group. Cortisol levels were elevated in the fish that were subjected to diazinon. Those subjected to diazinon after receiving HSPi showed a significant decrease in cortisol levels. In conclusion, the study suggests that HSPi-mediated HSP70 induction may have a protective effect. The presence of an HSP inducer offers a potential strategy to mitigate the consequences of diazinon exposure in stellate sturgeon.

“…At present, there are many problems that affect the sustainable management of sturgeon populations from the Iranian coastal waters of the Caspian Sea. Therefore, different models of population dynamics are required to reflect the status of sturgeon populations, the consequences of overexploitation and aspects related to environmental pressure (Karayev 2006;Bakhshalizadeh et al 2020). New approaches have emerged that combine aspects of ecosystem analysis and cognitive theory, such as those developed by Karayev (2006).…”

Demographic data of the great sturgeon, Huso huso, from the Iranian coastal waters of the Caspian Sea were derived from measurements of individuals with a fork length ranging from 84 to 255 cm, obtained from commercial fisheries. The maximum age of fish caught in the south Caspian Sea was 30 years. The estimates of the asymptotic length L∞ and the growth coefficient (K) were 265.255 cm and 0.062 per year for males and 275.78 cm and 0.08 per year for females, respectively. Total mortality rates obtained by Gulland's method were larger for males (0.64) than for females (0.46). Annual mortality rates were calculated as 47% for males and 37% for females. Data obtained in this study and their comparison with data from previous studies indicate that the great sturgeon stock is definitely exploited in an unsustainable manner.
