Abstract
The effects of two selected probiotics (Pseudomonas synxantha and Pseudomonas aeruginosa) on the specific growth rate (SGR), survival and immune parameters of juvenile western king prawns (Penaeus latisulcatus) were examined for 84 days. Pseudomonas synxantha and P. aeruginosa were either applied into the rearing medium or supplemented in the formulated feed at a concentration of 105 colony forming unit (CFU) mL−1 for each probiotic. The results showed that applications of the probiotics resulted in no significant difference (P>0.05) in the SGR and survival of the prawns, but significantly decreased the food conversion ratios (PPP. aeruginosa resulted in a higher health status of the prawns compared with P. synxantha. Overall, equal combinations (105 CFU mL−1) and volumes of P. synxantha and P. aeruginosa used as a supplement in the formulated feed resulted in an improvement in the health of the juvenile western king prawns.Keywords
