The biofloc system is an ecologically sustainable shrimp culture system. The conglomerates of beneficial bacteria, algae and protozoa in pond water serve as a water quality management system and as a feed additive to the shrimps. This study aimed to characterise the microbial communities associated with the biofloc pond water and the surface of Penaeus vannamei Boone, 1931, reared in it using the Illumina Miseq sequencing technology. The multiple alpha diversity measures indicated the shrimp surface samples to be richer in diversity than the pond water samples. Analysis of the bacterial community revealed that Proteobacteria, Bacteroidetes, Planctomycetes and Cyanobacteria formed the principal phyla. There was a shift in the relative abundance of bacterial communities at each time point. The operational taxonomic units (OTU) analyses revealed that 18.38 % OTUs were shared by the pond water samples, the shrimp surface samples shared 29.35 % at the three different time points. PICRUST analysis revealed that the bacterial communities in the biofloc rearing water, and shrimp surface, were likely involved in intensive microbial metabolism and core housekeeping functions. The information generated will help understand the bacterial community composition associated with optimal water quality and shrimp health in a biofloc culture system.

To observe the effectiveness of short time in-pond nursery of post larvae (PL) on the survival rate and production of shrimp (Penaeus monodon) under modified improved culture system, an experiment was conducted in earthen ponds at Brackishwater Station of Bangladesh Fisheries Research Institute, Khulna. Results of the experiment revealed that short time in-pond nursery of PL provided the significantly higher (p<0.05) survival rate (58%) than direct stocking of PL (47.81%) in the rearing pond. In-pond nursery of PL provided 9.95% better survival rate than direct stocking. The production of shrimp was 661 kg/ha under in-pond nursery of PL and it was 534 kg/ha under direct stocking of PL in rearing ponds. The production of shrimp was also significantly higher (p<0.05) under in-pond nursery system than direct stocking of PL in rearing ponds. Final weight gain and Food Conversion Ratio (FCR) values were similar in both the treatments. Water quality parameters in both stocking systems were insignificant and it was within the range of shrimp culture. In this study, the increment in production under in-pond nursery system was mainly due to the increase of survival rate in the respective treatment was ascertained.DOI: http://dx.doi.org/10.3329/pa.v19i2.16958 Progress.
