Determining the Effects of Bioaugmentation in Yield and Feed Consumption in Freshwater Shrimp - Aquaculture
Based on qualitative studies performed in Taiwan that demonstrated increased yield by weight of Tiger prawns grown in commercial shrimp ponds to which a bioaugmentation product had been added, a quantitative study was undertaken to determine statistically the improved yield, if any, on Macrobrachium rosenbergii. Feed was also monitored to determine biomass conversion efficiencies.
Earlier qualitative studies had assumed that the increase in shrimp yield, mostly due to increased size, was based mostly on improving the water quality of the shrimp ponds. The quantitative study suggests that there may also be other factors associated with the bioaugmentation product since the increased yield was realized with a reduction in feed use. There are two potential explanations for this. First, the bacteria may be acting as a probiotic and helping the shrimp to digest the food more efficiently thus extracting more nutrients from the feed.
