Preliminary results on siberian sterlet Fry rearing and their comparison with some production performance parameters of European sterlet

Özet

Larvae of the European (ARR) and Siberian (ARM) sterlets were fed initially with Tubifex, and further were gradually weaned to dry diet. Additionally two other feeding strategies were tested in ARM: feeding exclusively with dry diet, and sudden weaning from 10 day post-hatch (dph). Survival and yield at 30 dph of the ARM was significantly higher than that of ARR. Significant differences were found within ARM groups with different weaning strategies. We suppose that ARM has at least same potential for aquaculture than the ARR. Also we suggest that the initial use of live foods for ARM would be preferable
