“…It spawns in running waters with rocks, pebbles and other hard objects on the bed, or in pits and pools under waterfalls (Popov, 2017). Russian sturgeon is widely distributed in the Caspian Sea, the Sea of Azov and the Black Sea, as well as in the rivers flowing into these waters (H. Song et al., 2022). The water temperature requirement for the spawning of Russian sturgeon is 12–14°C (Elhetawy et al., 2020).…”

River damming has brought great benefits to flood mitigation, energy and food production, and will continue to play a significant role in global energy supply, particularly in Asia, Africa, and South America. However, dams have extensively altered global river dynamics, including riverine connectivity, hydrological, thermal, sediment and solute regimes, and the channel morphology. These alterations have detrimental effects on the quality and quantity of fish habitat and associated impacts on aquatic life. Indeed, dams have been implicated in the decline of numerous fishes, emphasizing the need for effective conservation measures. Here, we present a global synthesis of critical issues concerning the impacts of river damming on physical fish habitats, with a particular focus on key fish species across continents. We also consider current fish conservation measures and their applicability in different contexts. Finally, we identify future research needs. The information presented herein will help support sustainable dam operation under the constraints of future climate change and human needs.

“…With advances in the theory of quantitative genetics, breeders have successively proposed best linear unbiased prediction (BLUP), 6 which combines pedigree and phenotype records using all relevant information to estimate the breeding value (EBV) of individuals. Furthermore, with the development of computational technologies, BLUP (selective breeding) has been used to improve various economic traits in many aquaculture species, such as Vibrio alginolyticus resistance in Pacific oyster ( Crassostrea gigas ), 7 carotenoid traits in Chinese mitten crab ( Eriocheir sinensis ), 8 gill‐associated virus resistance in black tiger shrimp ( Penaeus monodon ), 9 tilapia lake virus resistance in Nile tilapia ( Oreochromis niloticus ), 10 growth and survival in rohu carp ( Labeo rohita ) 11 and growth and egg‐related traits in Russian sturgeon ( Acipenser gueldenstaedtii ) 12 . However, conventional BLUP yields low genetic gain for certain traits, such as traits with low heritability (e.g., disease resistance traits), traits that are difficult to measure (e.g., disease resistance and behavioural traits), sex‐restricted traits (e.g., reproductive and oviposition traits) and traits that require slaughter for measurement (e.g., meat quality and carcass composition traits), necessitating breakthroughs using novel breeding methods.…”

Since its introduction in 2001, genomic selection (GS) has progressed rapidly. As a research and application hot topic, GS has led to a revolution in the field of animal and plant breeding. Thanks to its ability to overcome the shortcomings of traditional breeding methods, GS has garnered increasing attention. Both theoretical and practical breeding studies have revealed the higher accuracy of GS than that of traditional breeding, which can accelerate genetic gain. In recent years, many GS studies have been conducted on aquaculture species, which have shown that GS produces higher prediction accuracy than traditional pedigree-based method. The present study reviews the principles and processes, preconditions, advantages, analytical methods and factors influencing GS as well as the progress of research in aquaculture into these aspects. Furthermore, future directions of GS in aquaculture are also discussed, which should expand its application to more aquaculture species.

Sturgeon broodstock management includes unavoidable handling and surgery procedures such as biopsy, endoscopy, laparotomy, oviduct incision inducing stress response. Clove oil and 2‐phenoxyethanol (2‐PE) are anesthetics commonly used in aquaculture to reduce the stress. The present study aimed to determine the anesthetic efficiency, hematological, histopathological and echocardiographic effects of clove oil and 2‐PE in adults Danube sturgeon (Acipenser gueldenstaedtii). Experimental fish were exposed to anesthetic baths to 20, 40 and 80 μl/L clove oil and 250, 500 and 750 μl/L 2‐PE concentrations and the induction‐recovery timed were recorded. The induction and recovery times in Danube sturgeon were significantly affected by clove oil and 2‐PE concentrations. The results showed that 2‐PE at 250–500 μl/L concentration failed to induce anesthesia; however, 750 μl/L concentrations induced anesthesia within 290 s. The optimum concentrations of clove oil showed in the present work were between 40 and 80 μl/L concentrations induced anesthesia within 180–120 s. The anesthetized fish showed alteration in hematological and echocardiographic indices was time dependent. RBC, HCT and LYM values in 40 and 80 μl/L clove oil and 750 μl/L 2‐PE groups were significantly lower than control group in 4th h. The mean heart rates were significantly affected before and after anesthesia treatment at clove oil. Whereas, no significant changes were observed in mean heart rates for 2‐PE. Fish anaesthetized with clove oil or 2‐PE exhibited histopathological deformity symptoms in the gill compared to control groups. In conclusion, the present study demonstrated that minimum effective concentration of clove oil was 40 μl/L for short‐term anesthesia, but 80 μl/L concentration is suitable for deep anesthesia. 2‐PE may not be suitable for adult Danube sturgeon due to long induction time and high concentration. It is also concluded that higher anesthetic concentrations may have detrimental effects on the fish gill tissue.
