Use of probiotics for improving soil and water quality in aquaculture ponds Academic Article uri icon

abstract

  • A number of biological products including live bacterial inocula, enzyme preparations, and extracts of plant products are being promoted for use as water and soil quality conditioners in aquaculture ponds and particularly in shrimp ponds. Although there is much anecdotal information about these products and considerable promotional material from vendors, little independent research has been conducted. Several studies have shown no benefits of bacterial inocula, but one recent study at Auburn University demonstrated higher survival of fish and thus greater net production in ponds treated frequently with live Bacillus of three species than in control ponds. No improvements in water quality were noted, and the mechanism by which the bacteria improved survival is unknown. Laboratory studies of a bacterial inoculum demonstrated a greater rate of nitrogen loss. Liming of laboratory …
