Bacterial diversity in organic manured fish ponds

Eleven bacterial species isolated from water and sediment media from organic manured carp cultured ponds with cow manure and biogas slurry comprised diverse bacterial strains of Methylococcus, Pseudomonas, Aquaspirillum, Bacillus, Planococcus, Micrococcus, Streptococcus, Lactobacillus, Listeria, Sporosarcina and Sporolactobacillus. Bacillus sp. (44.1%) along with other gram-positive forms like Planococcus sp. (14.3%) and Micrococcus sp. (10.7%) were the important microbial groups and their occurrence may be attributed to allochthonous organic enrichment and active sediment-water nutrient interactions
