“…There were 7 different genera identified and 1 unidentified from shrimp digestive system, muscle and body surface and shrimp rearing tank water and sediment. The isolated bacteria from different body parts of juvenile P. monodon and its rearing tanks were predominantly gram negative (72%), which is agreed with previous findings in egg, larvae and post larvae of Penaeus indicus (Hameed, 1993) and microflora of M. rosenbergii in hatcheries (Anderson et al, 1989;Phatarpekar et al, 2002;Kennedy, 2006). Similar finding was cited for wild P. japonicus (Yasuda and Kiato, 1980).…”

Bacteria flora of intestine and hepatopancreas, body surface and muscles of juvenile Penaeus monodon along with its rearing water and sediment was analyzed. Juvenile shrimp were reared in four tanks in the Hatchery complex, Department of Aquaculture, Faculty of Agriculture, University Putra Malaysia. Water quality parameters were measured every day. Samples were collected aseptically and homogenized before being inoculated in Tryptone Soy agar, Thiosulphate Citrate Bile Salt agar, MacConkey agar and Pseudomonas-isolating agar. There was no significant difference between water quality parameters and shrimp body weight of replicate tanks. Total plate count for water and total Vibrio count for rearing water and digestive system were within previous reported ranges. Eight different genera were isolated in which 7 genera were identified. Gram negative bacteria were dominant (72%) Vibrio was the most dominant genera followed by Shewanella and Burkholderia. Clavibacter followed by Staphylococcus were the most dominant gram positive bacteria. No coliform bacteria was detected in the shrimp body parts and rearing environment. Incidence of Shewanella in the digestive system was significantly higher than sediment, rearing water and muscles. This may be implied its ability to colonize in the digestive tract of juvenile P. monodon.

“…Bacterial counts of larvae ranged from 0.37 to 2.79 × 10 6 CFU, similar to the observations of Kennedy et al (2006) (2.35 × 10 5 CFU/10 larvae 1 to 4.35 × 10 7 CFU /10 larvae). TPC of LRT water also falls within the range given in the previous reports (Miyamoto et al 1983;Anderson et al 1989;Phatarpekar et al 2002). Bacterial count of larvae was higher than that of LRT water, similar to previous findings in M. rosenbergii (Anderson et al 1989;Miyamoto et al 1983;Kennedy et al 2006 (Yasuda and Kitao 1980).…”

We sought the source of gram-negative bacteria associated with giant freshwater prawns in a hatchery that was previously observed with severe mortality of prawn larvae during the sixth to seventh zoea stages. After thorough disinfection, the gram-negative bacterial microflora of broodstock, larvae, larval rearing tank (LRT) water, and other intake systems were examined for bacteria. Enterobacteriaceae and Vibrio were the major bacteria isolated from the larvae. The present study suggests that Enterobacteriaceae may be introduced via the broodstock and Vibrio via the LRT water.

“…Whereas, colourless colonies were found in SalmonellaShigella agar. Saha et al (1988) and Anderson et al (1989) also reported the dominance of gram negative bacteria in the gut of the Ma,crobrachiuin rosenbergii. This indicates LAB do not form autochthonous gut microflora of M. rosenbergit.…”
