Approximately 5300 hybrid sturgeons with an average body weight of 600-800 g were farmed in 3 round tankers measuring 3m in diameter each containing 28,000 L of aerated groundwater. According to the owner's description, the diseased fish had anorexia, pale body color, and reddish spots on the abdomen. The morbidity and lethality rates in this outbreak were about 70% (3706/5300) and 100% (3706/3...

The reintroduction of the extinct beluga sturgeon (Huso huso L.), an anadromous species with economic and traditional relevance, is a priority in next conservation strategies Northern Italy. EU-LIFE NATURA project aims to reintroduce Po River basin through captive breeding program.

This experiment wascarried out to explore the effect of use of combinations of permeating cryoprotectant and non permeating cryoprotectant on thequality of frozen-thawed Beluga (Huso huso) spermas compared to the use of permeating cryoprotectant as a control. For this work methanol (MeOH) and dimethyl sulfoxide (DMSO)are used aspermeatingcryoprotectantsand bovine serum albuminas a non permeatin...

Sturgeons are ancient and endangered species whose populations have been greatly reduced over the past few centuries due to habitat destruction overfishing for production of expensive caviar. All sturgeon listed in CITES Appendix II limit their trade; therefore, accurate identification is crucial. In this study, we performed whole-genome resequencing five species, including Kaluga (H. dauricus)...
