Abstract
Optimal and stable bloom development and water quality maintenance in the initial stage of low saline Litopenaeus vannamei semi intensive shrimp culture has always been a challenging issue. The research work involves the documentation on field performance of BLOOMAX™, a commercial probiotic in developing optimal phytoplankton bloom, maintaining remarkable water quality, nutrient status, phytoplankton abundance and diversity. Nutrient composition and physico-chemical parameters of water were monitored in test and control ponds and were found to be optimal for the production of shrimps in the treated ponds. However, bloom crash was observed in the control ponds. Phytoplankton diversity and abundance exhibited fourteen species of phytoplankton in BLOOMAX™ treated ponds and twelve species in control ponds. Test ponds demonstrated density of 256- 357×104 cells ml-1 and control ponds with 214-279×104 cells ml-1 with frequent crash which may be due to improper stoichiometric balance and other parameters.
