Abstract:
For establishing nitrification in prawn (non-penaeid, salinity 10–15 ppt) and
shrimp (penaeid, salinity 30–35 ppt) larval production systems, a stringed bed suspended
bioreactor (SBSBR) was designed, fabricated, and validated. It was fabricated with 5 mm
polystyrene and low density polyethylene beads as the substrata for ammonia and nitrite
oxidizing bacterial consortia, respectively, with an overall surface area of 684 cm2. The
reactors were activated in a prototype activator and were transported in polythene bags to
the site of testing. Performance of the reactors activated with the nitrifying bacterial
consortia AMONPCU-1 (ammonia oxidizers for non-penaeid culture) and NIONPCU-1
(nitrite oxidizers for non-penaeid culture) was evaluated in a Macrobrachium rosenbergii
larval rearing system and those activated with AMOPCU-1 (ammonia oxidizers for penaeid
culture) and NIOPCU-1 (nitrite oxidizers for penaeid culture) in a Penaeus monodon
seed production system. Rapid setting up of nitrification could be observed in both the
static systems which resulted in a higher relative per cent survival of larvae
