Changes in growth factors of Beluga, Huso huso larvae fed with bioencapsulated Artemia enriched by a probiotic, protexin
Artemia urmiana nauplii were used as a vector in bioencapsulation processing to carry blends of five probiotic bacilli called Protexin aquatic,including Bacillus circulans, B. subtilis, B. licheniformis, B. laterosporus and B. Polymyxa to digestive system of Beluga Huso huso larvae. Nauplii were bio...

The probiotic bacilli had significant positive effects on the specific growth rate, relative gain ratio, survival rate, average daily growth and thermal growth coefficient in comparison with control (P<0.05).
