“…The THC of M. rosenbergii juveniles after the experimental period (Table 7) showed a significantly higher THC than that of the T4 and T6 treatment groups ( P <0.05). The increase in the haemocyte count observed among M. rosenbergii juveniles in the present study was comparable to the observations of Cheng and Chen (2001) in M. rosenbergii and Chand and Sahoo (2006) in M. malcomsonii . Rodriguez, Espinosa, Echeverria, Cardenas, Roman and Stern (2007) reported increased THC in P. vannamei larvae and juveniles after treatment with the probiotic, V. alginolyticus .…”

Eight hundred and eighty-¢ve strains of bacterial isolates from various samples associated with the natural habitat of Macrobrachium rosenbergii were screened for their probiotic potential. Two putative probionts namely Bacillus NL110 and Vibrio NE17 isolated from the larvae and egg samples, respectively, were selected for experimental studies and were introduced to the juveniles of M. rosenbergii (0.080 AE 0.001g) through di¡erent modes such as through feed, water and both. The probiotic potential of the above bacteria in terms of improvements in water quality, growth, survival, speci¢c growth rate (SGR), feed conversion ratio and immune parameters was evaluated. The treatment groups showed a signi¢cant improvement in SGR and weight gain (Po0.001). Survival among di¡erent treatment groups was better than that in the control group. There were also signi¢cant improvements in the water quality parameters such as the concentration of nitrate and ammonia in the treatment groups (Po0.05). Improvements in immune parameters such as the total haemocyte count (Po0.05), phenoloxidase activity and respiratory burst were also signi¢cant (Po0.001). It is concluded that screening of the natural micro£ora of cultured ¢sh and shell¢sh for putative probionts might yield probiotic strains of bacteria that could be utilized for an environment-friendly and organic mode of aquaculture.

“…The fusiform cells varied from 57.81 to 73.14%, large ovoid cells from 18.89 to 28.45% and small round cells from 7.97 to 15.7% in different groups of experimental prawns. These types of haemocytes in this species were also described earlier [2,20,45]. Similarly, Vazquez et al [35] also found 70% fusiform or hyaline haemocytes, 20% granular haemocytes and 10% agranular haemocytes in the intermoult M. rosenbergii.…”

“…Other health assessors include cell recognition, phagocytosis, melanization, cytotoxicity and cell‐to‐cell communication (Johansson et al 2000). Other studies found that THCs decreased when western rock lobsters ( Panulirus cygnus ) were exposed to air (Fotedar et al 2001), when prawns ( Macrobrachium malcolmsonii ) were exposed to NO 2 ‐N at 0.063 and 0.314 mg L −1 for 120 h (Chand & Sahoo 2006) and when white prawns ( Litopenaeus vannamei ) were exposed to 488 μg L −1 sulphide (Hsu & Chen 2007). Total haemocyte count in lobsters ( Homarus americanus ) (Stewart, Cornick & Dingle 1967) and in the blue crab ( Callinectes sapidus ) (Johnson 1976) declined in the presence of harmful bacteria and THCs were lower in moribund western rock lobsters than in the healthy ones (Jussila et al 1997), but in the current study the THCs of the prawns were higher following application of the probiotics, indicating that probiotics have a positive effect on the health of prawns.…”

The e¡ects of two selected probiotics (Pseudomonas synxantha and Pseudomonas aeruginosa) on the speci-¢c 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 10 5 colony forming unit (CFU) mL À 1 for each probiotic. The results showed that applications of the probiotics resulted in no signi¢cant di¡erence (P40.05) in the SGR and survival of the prawns, but signi¢cantly decreased the food conversion ratios (Po0.05) compared with the control where no probiotics were applied. The supplement of the probiotics with the formulated feed enhanced the probiotic numbers in the intestines of the prawns and low bacteria numbers in the haemolymph. The prawns were signi¢cantly (Po0.05) healthier, as indicated by the immune response obtained when both probiotics were given in combination compared with when individual probiotics were used. When applied singly, P. aeruginosa resulted in a higher health status of the prawns compared with P. synxantha. Overall, equal combinations (10 5 CFU mL À 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.
