“…16.6%) was reported in Siberian sturgeon larvae (22 days posthatch and 13 days after initiation of feeding) (Gisbert and Williot, 1997). Mortalities of Atlantic (Mohler et al, 1996;Bardi et al, 1998) and lake sturgeon (DiLauro et al, 1998) larvae, however, were much higher than those of white, green, and Siberian sturgeon kept under optimum conditions for the first 4 -5 weeks after initiation of feeding. Differences in larval mortality may have resulted from within and among species differences, environmental (feed and water) conditions, and quality of care and maintenance of larvae, etc.…”

“…At present, commercial non-purified semi-moist rainbow trout diets and starter diets for marine fish are commonly used to raise young sturgeons (Hung, 1991a;Gisbert & Williot, 1997;Bardi et al, 1998). In the case of Siberian sturgeon, larvae are fed under both experimental and commercial conditions with a dry commercial diet that contains 50% protein, 15·5% lipid, 20% carbohydrate and 8% ash (Lansy A2 and W3, Artemia Systems, Belgium), while A. transmontanus larvae are feed with a semi-moist diet containing 20·1% moisture, 42·5% protein, 16·8% lipid, 11·6% carbohydrate and 10% ash (Biodiet #2 and #3, Bio-Oregon, Oregon, U.S.A.).…”

Since first large-scale attempts to culture sturgeon from the larval stage were carried out in the former U.S.S.R. at the end of the nineteenth century, rearing technology has advanced considerably during the last 20 years and noticeable improvements in incubation and larval rearing techniques have been implemented in normal hatchery procedures. Siberian sturgeon eggs are incubated in MacDonald jars at 13-14 C to prevent fungal infections. Mass hatching takes place 7 days after fertilization and hatching rate can be predicted as a function of the percentage of eggs fertilized. Survival at the end of the endogenous feeding stage is correlated with hatching rate. Egg size has no direct implications for larval growth and survival of Siberian sturgeon. Experimental studies have demonstrated that behavioural observations are useful criteria to assess the quality of larvae and to synchronize the physiological state of fish with the appropriate rearing procedures. Special attention should be given to the transition to exogenous feeding, where cannibalism, difficulties in adaptation to a new diet, overfeeding and resulting bacterial infections dramatically reduces survival to the fingerling stage. Although a commercial artificial diet specifically formulated for larvae of Siberian sturgeon and other acipenserids is still lacking, commercial non-purified rainbow trout diets and starter marine fish diets are currently used and their results are reasonably acceptable in terms of larval growth and survival. Further research must be focused on the determination of egg quality indicators in order to provide the producer with the tools to estimate the viability and performance of the progeny.

“…Mortality during this period is characteristic of other sturgeon species and stems from problems encountered during the transition to exogenous food once resources of endogenous food are depleted (Bardi et al 1998). Mortality was noted in both groups studied mainly among weaker individuals that did not feed and often exhibited wounds in the caudal section of the body.…”

Abstract. The aim of this experiment was to assess the impact live and formulated diets had on the growth and survival of larval Atlantic sturgeon, Acipenser oxyrinchus Mitchill. In the first experiment, the results of feeding the fish decapsulated (group D) and undecapsulated (group ND) Artemia sp. cysts were compared. Increases in the body weights and lengths of the fish fed decapsulated and undecapsulated Artemia sp. were similar at values that were not statistically significant. Survival in the larval group fed undecapsulated Artemia was higher in comparison to the group fed decapsulated Artemia (95.0 and 82.8%, respectively). In the second experiment, three commercial starter feeds were used: Aller ArtEX (Aller Aqua, Poland; group A), Nutra HP (Skretting, France; group H), and Perla Prolarvae (Spa Hendrix, Italy; group P). Following 35 days of culture, no differences were noted in fish growth with lengths in the different groups ranging from 28 to 30 mm and weights from 119 to 134 mg. Fish survival in group A was 55% and was significantly statistically higher than that in groups H and P at 31.7 and 35.7%, respectively. The results of the experiment suggest that the best feed for the early stages of Atlantic sturgeon culture is undecapsulated Artemia during the beginning of exogenous feeding followed by an Artemia-based feed in the initial period of feeding with formulated diets.
