In this study, the effects of different diets on growth rates of Gammarus Pontogammarous meoticus were determined. A biomass of 1.5 g Gammarus with an average length of 7 ± 0.25 mm was transferred to the glass aquaria with volume 900 cm3 (volume 2.5 l). The Gammarus were fed with diets include baked potato (treatment 1), 30 percent yeast and 70 percent potato, (treatment 2), 50 yeast percent an...
this study was accomplished to investigate the effect of artemia urmiana nauplii enriched with pediococcus acidilactici as probiotic on growth performance and survival rate of great sturgeon, huso huso. artemia nauplii were enriched with p. acidilactici at a final concentration of 1010 cfu ml-1 in three time dependent treatments as 3 h (t3), 6 h (t6), 9 h (t9), and one non-enriched artemia as ...
