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

Popis výsledku v původním jazyce

The feeding rate effects were studied on the growth performance of gynogenetic diploid larvae of sterlet Acipenser ruthenus during the first 4weeks of exogenous feeding. The experimental rearing was conducted from 7 to 38days post-hatch (dph) in a circulation system. This was set up in four groups with three replicates (440individuals/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 (44L volume, 10individuals/L) with the temperature maintained at 18 +/- 0.5 degrees 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 +/- 1.2mm and 607.3 +/- 36.1mg (n=30) at 38dph. Highest TL and WBW of control larvae (AC) were recorded with 49.5 +/- 3.8mm and 600.8 +/- 88.0mg (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 7dph 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 38dph strongly depends upon the types of feed rather than the genome manipulation performed.
