This study was carried out to evaluate the effect of Probiotic (Bacillus spp.) on growth and survival rate and nitrogenous excretion in Rainbow Trout (Oncorhynchus mykiss) larvae. Rainbow Trout larvae were fed on Artemia parthenogenetica nauplii enriched at suspension of five probiotic bacilli at doses of 0, 1×108, 2×108 and 3×108 (CFUl-1).The feeding level was 30 percent of total biomass per day. The daily ration was divided into four feeding portions. The end all the trout larvae were sampled for biometry and growth determination. Feces were collected twice a day by pipetting and ammonia and urea contents in each tank were determined.
