“…Unlike the findings of Dilauro et al (1998) and Bardi et al (1998), our findings proved that H. huso larvae readily accept co-feeding of live food and FD from first feeding onwards, and are easily weaned to FD as monodiet within 7 days from the onset of exogenous feeding.

“…This has prompted a great deal of interest in the develop-ment of an artificial larval microdiet (MD) as an economic alternative to live food. The successful use of Artemia nauplii alone or co-fed with a commercial diet at the start feeding or during early development of different sturgeon species has been reported by a number of researchers (Bardi et al 1998;Dilauro, Krise & Fynn-Aikins 1998;Mohler, Kim King & Farrell 2000;Volkman, Pangle, Rajchel & Sutton 2004). This may be due to the composition, palatability or physical characteristics of the dry feed (Person Le Ruyet, Alexandre, Thebaud & Mugnier 1993), to the larva's inability to properly digest the feed (Holt 1993;Kolkovski, Tandler, Kissil & Gertler 1993;Walford & Lam 1993;Zambonino Infante & Cahu 1994), or to the low attractiveness of the non-mobile particle for the fish larva.…”

Fine tuning of feeding practices for hatchery produced Persian sturgeon,Acipenser persicusand Beluga sturgeon,Huso huso

In this work, we investigated the effects of various feeding treatments on the survival and growth of Huso huso and Acipenser persicus larvae during a 20day culture period. Three replicate groups (250 fish/replicate) of first-feeding larvae were fed according to four main feeding regimes: (1) live food (live nauplii of brine shrimp Artemia urmiana); (2) indirect transition (5-7 days live food followed by gradual transition to formulated diet); (3) direct transition (using different combinations of live and formulated diet from the start feeding onwards); and (4) formulated feed (FD) from the start of feeding. In H. huso larvae, combining live food and manufactured diets (co-feeding) from the first feeding stage onwards (direct transition) resulted in significantly higher weight gain than the other regimes. Survival was significantly higher in H. huso larvae fed solely live food or the direct transition regimes compared with indirect transition and FD. In A. persicus larvae, growth and survival were higher in the indirect transition feeding regime than in the other regimes. On the basis of the results of this study, we recommend co-feeding of H. huso immediately from the commencement of exogenous feeding, but co-feeding of A. persicus should start 7 days after prior feeding with live food.

“…The positive effects of live food on growth and survival rate of sturgeon juveniles were reported earlier for Atlantic sturgeon Acipenser oxyrinchus desotoi (Bardi & Chapman, ), lake sturgeon Acipenser fulvescens (Di Lauro, Krise, & Fynn‐Alkins, ), beluga Huso huso, and Persian sturgeon Acipenser persicus (Ebrahimi & Zare, ). Several studies showed that larvae of Siberian sturgeon Acipenser baerii (after yolk sac resorption) initially fed a composition starter exhibit lower growth performance and survival (Gilsbert & Willot, ; Hamlin, Michaels, Beaulaton, & Main, ).…”

Effects of feeding rate on the growth performance of gynogenetic albino sterlet,Acipenser ruthenus(Linnaeus, 1758) larvae

et al. 2017

Summary The feeding rate effects were studied on the growth performance of gynogenetic diploid larvae of sterlet Acipenser ruthenus during the first 4 weeks of exogenous feeding. The experimental rearing was conducted from 7 to 38 days post‐hatch (dph) in a circulation system. This was set up in four groups with three replicates (440 individuals/replicate), viz: AC‐control larvae fed Artemia sp., CFC‐control larvae fed compound feed, AG‐gynogenetic larvae fed Artemia sp., and CFG‐gynogenetic larvae fed compound feed. The larvae were reared in glass tanks (44 L volume, 10 individuals/L) with the temperature maintained at 18 ± 0.5°C, photoperiod of 12L:12D and water flow regime of 1‐L/min and fed 50%, 25%, 25%, and 9% of their total biomass/day during feeding. Highest TL and WBW of gynogenetic diploid larvae (AG) were observed with 50.6 ± 1.2 mm and 607.3 ± 36.1 mg (n = 30) at 38 dph. Highest TL and WBW of control larvae (AC) were recorded with 49.5 ± 3.8 mm and 600.8 ± 88.0 mg (n = 30), respectively, with 73.1% ± 11.4% survival; the lowest survival rate was at 46.4% ± 7.1% (n = 30) for the CFG group. The results indicate that the gynogenetic and normal larvae of sterlet fed with live food (Artemia nauplii) from 7 dph can achieve higher growth and survivability compared to the larvae fed with formulated test feed. Results of this study suggest that the effective rearing of sterlet larvae from 7 to 38 dph strongly depends upon the types of feed rather than the genome manipulation performed.

Development of a Growth Model for Lake Sturgeon

This study evaluated the relationship between temperature and growth rate of juvenile Lake Sturgeon Acipenser fulvescens and determined optimal temperature for growth based on weight gain and length increase. Four temperature regimes (12.0 ± 0.5, 17.0 ± 0.3, 21.6 ± 0.4, and 26.8 ± 0.6°C [mean ± SD]) were tested in triplicate to determine specific growth rates and daily length increases. In addition to growth rate, consumption rates were also assessed by recording the grams of feed offered to fish and the amount uneaten to ensure all fish were fed to satiation. Lake Sturgeon consumed 2.76, 9.63, 13.69, and 14.22% body weight/d, respectively, and grew at a specific growth rate of 0.50, 1.42, 2.01, and 1.75 mm/d, respectively. Fish consumed more food with increasing water temperature; however, daily length increase declined at 26.8°C. This study may be used to construct growth models for production programs, project size at stocking, and project feed rates based on water temperature.
