Effect of feeding with HSP stimulated in yeast on growth, survival and tolerance against environmental stress on two species of A. franciscana and A. urmiana

Biotechnological enhancing of growth, survival and tolerance of aquatic animals against to environmental stress, especially at larval stage of animals, is one of the important research topics. Stimulation of heat shock proteins is one the alternatives which can be exchanged with antibiotic and vaccines consumption. The present research aimed to study the effect of feeding of Artemia with HSP stimulated in unicellular yeast against environmental stresses. The study was conducted with stimulating of HSP with high salinity and temperature stresses. After ensuring of up-regulation the HSP in the yeast by SDS-Page methods, both species of Artemia were fed by the yeast and unicellular algae Dunaliella tertiolecta. 20 days culture period using this food revealed the positive effect of HSP on growth and stress tolerance of Artemia at environmental sever stresses of 250 g/l and 34°C (p<0.05).
