Within 17 September – 31 October 1997, fry of the Russian × Siberian sturgeon hybrid of 31.1 g mean individual weight and sterlet fry of 25.4 g mean individual weight were fed two trout feeds: the Dana–ex 4.85 and the Safir differing, i.a., in their gross energy content (5470 and 5173 Kcalˇg–1, respectively), each feed being offered in triplicate. The fish were kept in cages, stocked at 80 ind./cage, placed in power station cooling water of temperature changing within 12.2–23°C. Water temperature–dependent differences in fish growth were revealed: the hybrid grew better at 19–23°C, while the sterlet growth was better at 12–18°C. In both fish groups, the Dana–ex 4.85 produced better food conversion rate (FCR) and apparent net protein utilisation (aNPU).

Chemical deglycosylation (dg) of sturgeon Acipenser gueldenstaedti Br. (alphaGTH) resulted in the loss of 83% of its initial carbohydrate content. It altered also recombinant dgalphaGTH + betaGTH dimer molecule, reducing its immunoreactivity by 30%, and fully blocking the hormonal function. CD spectroscopy showed that deglycosylation led to changes in the secondary structure of dgalphaGTH and in the alpha-beta recombinant. The sugar moiety of sturgeon alphaGTH is suggested to play an important role in maintaining the biological function of the hormone dimer molecule.

Exotic species of acipenserid fishes have been frequently encountered in the commercial catches of the Baltic Sea, since the early 1990s. Such sightings are rarely reflected as published records. The present paper provides detailed descriptions of two specimens of Russian sturgeons, Acipenser gueldenstaedtii caught in the Exclusive Polish Economic Zone of the Baltic Sea.

Sturgeon frywere obtained through the artificial spawning of Siberian sturgeon (Acipenser baeri Brandt) and the hybrid of Siberian and Russian sturgeon (Acipenser baeri Brandt x Acipenser gueldenstaedti Brandt). Selected biotechnological factors of the fish were compared and biometric measurements were taken during a 60-day long rearing period in a recirculation system. A higher growth rate was confirmed in the hybrid sturgeon. The average body weight of the hybrid at an age of nine months was 1,078 g, while that of the Siberian sturgeon was 872 g. The hybrid also utilized feed more efficiently. The food conversion rate during the study period was 0.64 for the hybrid and 0.66 for the Siberian sturgeon. The greatest differences in the plastic features of the studied fish were found for those related to the head. The Siberian sturgeon had a longer rostrum (R) and a shorter post-orbital space (op) than did the hybrid. Significant differences were also observed in the numbers of lateral bony plates (Sl), the number of rays in the dorsal fins (D) and the number of rays in the anal fins (A).

The aim of the studies was to determine the impact of the feed supplement Vitaton, a preparation containing b-carotene, on the growth rate, feed utilization, and meat quality of reciprocal back cross hybrids of Siberian sturgeon, Acipenser baerii Brandt × green sturgeon, Acipenser medirostris Ayres, (SSZ group) and Siberian sturgeon × Russian sturgeon, Acipenser gueldenstaedti Brandt, (SRS group). It was confirmed that b-carotene results in a statistically significant increase in growth rate of about 20% and a decrease in the value of the feed conversion ratio (FCR) by 9.6% in the fish from the SSZ group. Statistically significant differences between the Vitaton and control subgroups in the SRS group occurred only with regard to the FCR at values of 1.64 ± 0.08 and 1.71 ± 0.09, respectively. The results of meat quality tests indicated that under the influence of Vitaton there was a statistically significant increase in the fat content to 13.21 ± 1.04% in comparison with the control group values of 9.57 ± 2.33% and a decrease in the water content from 72.73 ± 1.57% to 68.82 ± 1.28% in the fish from the SRS group. No significant impact of b-carotene was noted in the studied fish with regard to meat color.
