Farming sturgeons is an economically important practice in a number of Asian and European countries. However, since it is not widely implementedin Turkey, fertilized eggs necessary for research and industrial activities are imported from Germany. Due to the interest of several fish farms in culturing sturgeon in Turkey and the lack of relevant data, this study investigated bacteria related heal...

this study compared the effects of different levels of dietary fat on growth performance, liver enzymes and blood biochemical of juvenile siberian sturgeon (acipenser bearii) was designed for 12 weeks. for this reason 135 fish (15.6 ± 0.33g; mean ± sd) at nine 500 liter fiberglass tanks, each one containing 15 fish. three experimental diets with the same protein (42 %) and 3 fat levels 10, 15 a...

Oxygen consumption rate (MO2) and critical swimming speed (Ucrit) of juvenile Siberian sturgeon Acipenser baerii were measured at 24°C using a step-wise velocity test in a flume-type respirometer. Swimming behavior was video-recorded before and after the swimming experiment in a respirometer and an open tank. The relationship between MO2 and swimming speed (U) can be accurately described by a p...

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)...

Experiments compared intestinal HCO3- secretion in the intestine of marine teleost Gulf toadfish, Opsanus beta, to representatives of early chondrostean and chondrichthyan fishes, the Siberian sturgeon, Acipenser baerii, and white-spotted bamboo shark, Chiloscyllium plagiosum, respectively. As seen in marine teleosts, luminal HCO3- concentrations were 10-fold plasma levels in all species when e...
