Biol.Fish. 48:25-71 Comments: During the period of marine life, the adults mainly inhabits the pelagic zone descending at depths of 160-180 m Juveniles occur in shallow riverine habitats during their first summer. |

Developmental trait (?) | Spawning References: Cheung WWL, Pitcher TJ, Pauly D (2005) A fuzzy logic expert system to estimate intrinsic extinction vulnerabilities of marine fishes to fishing. Biol. Conserv. 124:97-111 Comments: Spawns in the main course of large and deep rivers with strong current and on stone or gravel bottom. |
Characteristic feeding method / Life stage (?) |
References (not structured): Rochard E, Castelnaud G, Lepage M (1990) Sturgeons (Pisces:Acipenseridae); threats and prospects. J. Fish Biol. 37 (A): 123-132 Comments: Feeds mostly on sea fishes (Black Sea whiting, anchovies, flatfishes, gobies, fry of bottom-living fishes), also crustaceans, mollusks, mysids and amphipods. The main food of juveniles appears to be insect larvae, especially of Ephemeroptera, crustaceans. |

Known human health impact? | Known References: Hamzeh, A., Moslemi, M., Karaminasab, M., Khanlar, M. A., Faizbakhsh, R., Batebi Navai, M., Tahergorabi, R. 2015. Amino acid composition of roe from wild and farmed beluga sturgeon (Huso huso). Journal of Agricultural Science and Technology, 17(2), pp. 357-364. Comments: Caviar is one of the valuable and most popular fish products all over the world that are obtained from sturgeons. There is some evidence that PCPs and other dangerous chemicals may be retained with the eggs of beluga sturgeon. Small traces of environmental toxins appear in caviar. |
Known economic impact? | Known References: Chakrabarty, P. 2003. "Huso huso" (On-line), Animal Diversity Web. Accessed July 15, 2024 at https://animaldiversity.org/accounts/Huso_huso/ Comments: Female beluga can produce 12 % of their body weight in caviar and beluga caviar can demand $200/kg. This species has become so depleted that its survival is supported entirely or nearly entirely by hatcheries throughout its limited range. |
Known measurable environmental impact? | Known References: Chakrabarty, P. 2003. "Huso huso" (On-line), Animal Diversity Web. Accessed July 15, 2024 at https://animaldiversity.org/accounts/Huso_huso/ Comments: Beluga are the largest piscivores in the Pronto-Caspian region. It difficult to determine their role in the past given their endangered status, but in periods where they were quite abundant (before 1950) they would have been among the top predators in the Ponto-Caspian, playing a similar role as the fish eating seals of the region. |
