The effect of feeding with Saccharomyces cerevisiae extract(Amax) on ammonia and urea excretion in Persian sturgeon (Acipenser persicus) larvae by bioenrichment of Daphnia magna
Journal Title: Journal of Research in Biology - Year 2011, Vol 1, Issue 2
Abstract
Acipenser percicus larvae (mean weight:80mg) were fed enriched with Daphnia and Saccharomyces cerevisiae product (Amax) to ammonia and urea excretion in two conditions of starvation and satiation. Persian sturgeon larvae were fed by bioencapsulated Daphnia with Amax in three concentrations (50, 100 and 150 mg/l Amax) for four consecutive weeks also control larvae were fed by nonbioencapsulated Daphnia. They were acclimatized to the laboratory conditions for 10 days before starting of the experiment. Moreover, a 12 h dark: 12 h light photoperiod was provided. The amount of postprandial Ammonia and urea excreted by Acipenser percicus larvae within 24 h was related to dose of Amax in broth. also results showed when larvae were fed with 50,100,150mg/l Amax, has decreased ammonia and urea excretion. Lower amount of ammonia(.093) and urea(.030) excretion in satiation condition and urea(.016) excretion in starvation condition were observed in treatment with 150 mg/l Amax (P < 0.05).but there is no significant different about ammonia excretion in starvation between other treatments (P > 0.05). Results indicate that use of probiotics Saccharomyces cerevisiae product (Amax) can reduce the amount of ammonia and urea excretion interestingly
